II. CEO Message

Earnings Release | 3Q.2021

Banco Santander México

Héctor Grisi, Banco Santander México’s Executive President and CEO, commented: “During the quarter we continued advancing on our strategic priorities while maintaining a strong balance sheet and liquidity positions. Loan volumes continue lagging, mostly among commercial loans, in line with market trends and still soft demand conditions. However, we are optimistic, as we have started seeing a slight sequential upturn in certain loan segments. Another bright spot is our individual loans, which continue outpacing the market, supported by sustained market share gains in mortgages and auto loans. In addition, consumer and SME loans are now showing signs of a gradual sequential recovery, as economic activity starts to gather speed and our risk appetite in these segments has grown correspondingly.

For the third consecutive quarter, our deposits remained relatively stable sequentially. The high liquidity has allowed us to focus on improving our deposit mix by favoring demand deposits over term ones. In fact, our current deposit mix stands at 74% demand and 26% term, our best ratio ever. Both our individual and corporate demand deposits continue expanding at low double-digit rates year-over-year, underscoring the success of our loyalty and customer acquisition strategies as well as our focus on lowering funding costs.

Our asset quality also improved during the quarter, as NPLs continued falling, aided by improving economic conditions in Mexico and our sound loan portfolio, which still reflects our prudent risk management. We are also approaching a normalized level of provisions as our operating environment becomes healthier. Accordingly, our cost of risk has declined to its lowest level in the last five quarters, and we expect it to continue converging gradually to pre-pandemic levels.

Although domestic and global economic conditions are improving, they will likely remain uneven and challenging. Nevertheless, our strategy remains focused on further strengthening client loyalty and driving digitalization, with the same ambition to become the bank providing the best customer experience in Mexico.

We continue working on growth initiatives by leveraging a host of new digital tools and methodologies and also by further enhancing our internal operating processes. With a focus on prudent and profitable growth, we continue making new investments in the bank’s transformation, mainly in IT and digitalization, while seeking efficiencies and maintaining tight cost controls across business lines.”

Strategic initiatives and commercial actions

Banco Santander Mexico is one of the leading financial groups in the country, focused on business transformation and innovation. The economy is changing fast. Digital technology is transforming markets as well as business models. In this highly competitive environment, the Bank must work in new ways to keep positioning itself as a market leader in value-added products. Therefore, investing in technology puts Banco Santander Mexico at the cutting edge of the industry and strengthens its value proposition, as well as focusing on customer experience which drives the Bank to improve its services and build loyalty. The Bank's strategic priority is to enhance the breadth of its products, digital offerings, distribution network and the overall customer experience to attract potential customers while building a stronger franchise to effectively address the challenges and seize the growing opportunities ahead.

The most relevant aspects of the third quarter are highlighted below:

The Bank’s strategic priorities are complemented by a new breadth of products and services, which will allow to cater its customers more comprehensively.

This quarter, the Bank launched the “LikeU” credit card, which combines a unique digital experience. The first in Mexico with “on-demand services” a new concept to personalize benefits, with the highest security specifications, and the only one that allows users to support six of the main causes of Social Responsibility in the hands of prestigious organizations in the country. Through this new offer, Banco Santander México strongly believes that will be doubling the acquisition of new accounts, helping to grow steadily and organically the loan portfolio, without living aside prudent risk management. In addition, the internal goal of the Bank is to issue 1 million cards in 12 months; just 7 weeks after being launched, the Bank have already issued 177 thousand Like U cards.

In line with Santander Group’s strategy, Banco Santander Mexico is working on the transformation of the collections and payments industry through “PagoNxt”. As part of this initiative, PagoNxt announced the acquisition of 70% of its technological partner “Mercadotecnia, Ideas y Tecnología” (MIT) to accelerate the development of the global payment franchise in Getnet stores, with a special focus on Mexico. MIT and Getnet have had a close relationship of more than 15 years in

Earnings Release | 3Q.2021

Banco Santander México

Mexico, thus the acquisition of MIT will allow Getnet to establish itself as the payment platform with the largest number of functions in Mexico. Together, they will continue adding value to large corporates, middle-market, and SMEs, accompanying them with technological solutions for their collection needs for both; cards and digital payments. Currently, GetNet Mexico is the second largest merchant in POSs and affiliations in the market, and third in number of transactions processed through the acquirer.

During this quarter, an alliance between the Bank, Mastercard and Getnet was announced, been a disruptive effort in the market where Santander Mexico will play a central role by being the first bank in the country to have 100% of its Mastercard credit and debit cards ready for contactless payments. Meanwhile, Getnet will contribute its more than 250 thousand points of sale terminals, where 80% accept contactless payments; while Mastercard will provide its payment platform that allows contactless transactions to be up to 10 times faster. The use of Contactless Payments technology, in addition to being a much more agile, comfortable, and secure experience compared to cash, will reinforce the safety and hygiene measures of the new normal under the context of the pandemic, in order to maintain a healthy distance and minimize physical contact.

In September, Soriana, a leading Mexican company in the consumer sector, joined the bank's Network of Correspondents. With this alliance, the Bank added more than 760 points of service for its customers and users to make deposits and payments to Santander cards at their nearest store without going to a branch. The incorporation of Soriana as another of the bank’s correspondents will complement the Branch Network, which currently consists of 9 correspondents that provide us +29,500 complementary branches, supporting the Financial Inclusion by taking banking services to unbanked areas and rural areas.

Santander reiterates its commitment to expand its coverage for customers and users. For this reason, the Bank expanded the alliance with OXXO, and now customers will be able to make cash withdrawals from their debit cards at the checkouts of the more than 19,880 OXXO stores, thus expanding the current offer of the 1,039 branches and 9,564 ATMs located throughout the country. The aforementioned is a key strategic alliance for the Bank, according to figures from the National Banking and Securities Commission (CNBV as per its Spanish acronym), OXXO, is considered the country's main bank correspondent.

Autocompara, the Bank's auto insurance comparator, will be the first digital platform to offer multi-annual insurance for vehicles. Now, clients will be able to quote and compare the best option for multi-annual insurance among seven companies, saving up to 20%. Furthermore, Autocompara's agreement with the insurers guarantees the benefit of having a fixed premium during the entire period of the insurance. Multi-annual insurance is an increasingly demanded service, and usually has increases in the renewal premium due to claims, so this option provides clients the freedom to choose more competitive insurance options.

Santander Mexico continues to innovate in the SME segment boosted by the alliances made with fintechs. Now, the Bank offers a unique digital experience to its customers by increasing the number of functionalities on the SME platform. In alliance with Avanttia, the Bank offers a collection manager that improves cash flow, billing, and administration services. In association with LendInc., a smart-financing platform, the Bank provides an entirely digital process for credit applications and a credit conditions simulator. Also, through Numina, the Bank is creating synergies to offer payroll advances to SMEs. Overall, the goal is to offer value added products to attract potential clients.

This quarter, Santander increased its market share in auto loans by 1.4 pp QoQ to 10% (as of August) maintaining the 4th position in the market. All this, thanks to the alliances that the bank has with Honda, Mazda, Tesla, Suzuki and Peugeot, together with Super Auto Santander, platform that integrates the commercial and insurance offering in one place, allowing to offer an online pre-approval in less than 10 minutes, allowing customers to have a brand-new car in less than 24 hours.

The consolidation of the Hipoteca Online digital platform continued, being the only platform in Mexico that connects all processes from end to end. In the quarter, the platform processed 96%

Santander continues to be the only bank in Mexico that offers a tailored interest rate based on the client's profile.

The Bank continues to increase the number of its digital and mobile clients by 10% and 13% YoY, respectively. Besides, the ratio of loyal customers continues to grow, now loyal clients represent 40% of active clients (vs 37% in the third quarter of 2020).

We are committed to integrating into our operation the criteria, policies and internal processes that guarantee the care of the social and environmental aspects that demand of us, both sustainability and the 2030 Agenda for Sustainable Development.

As of September 2021, commercial loans decreased 10.1% YoY, or Ps.46,116 million, due to decreases of 25.8%, or Ps.23,693 million in corporate loans, 17.2%, or Ps.11,802 million in SMES loans, 2.4%, or Ps.4,979 million in middle-market loans, 28.3%, or Ps.3,122 million in financial institutions loans and 3.1%, or Ps.2,521 million in government entities loans. The YoY decrease still reflects the exceptionally high comps of 2020 and still soft demand conditions. Sequentially, commercial loans decreased 0.2% or Ps.661 million.

Mortgage loans continued showing robust growth, increasing 14.3% YoY, or Ps.23,537 million and 3.1%, or Ps.5,622 million sequentially. The “Hipoteca Plus” product remains a main driver behind this strong performance, accounting for 57% of total mortgage origination in the quarter, which also helps the Bank to increase cross-selling of other products, mainly insurance and credit cards and building customer loyalty. In addition, the digital onboarding platform for mortgages, “Hipoteca Online”, has been a game changer, as it helps streamline processes and eliminates the need to visit a branch. During 3Q21, 96% of the mortgages were processed through this digital platform. However, the total mortgage loan portfolio is still affected by the run-off of acquired portfolios, excluding this effect, the mortgage portfolio would have increased 18.7% YoY, almost twice as much as the market growth.

It is worth noting that auto loans continued showing a solid performance, increasing 3.0x in September 2021 with respect to September 2020 and a 12.2%, or Ps.1,656 million, sequentially. This was a result of the Bank alliances with leading automakers, such as Honda, Mazda, Suzuki, Peugeot and Tesla, among others. According to the last information published by CNBV, as of August 2021, market share in this business was 10.0% vs. 2.9% a year ago.

Credit card loans contracted 5.3% YoY, or Ps.2,842 million, and 1.0% QoQ, or Ps.535 million, despite an average usage increase of 20.5% YoY, although a decrease of 3.2% QoQ, while, personal and payroll loans decreased 18.5% YoY, or Ps.3,270 million, and 3.2% YoY, or Ps.1,195 million, respectively, affected by weak demand conditions and the Bank’s cautious approach. In addition, in September 2021 the Bank launched a new and innovative credit card named “LikeU”. This card is 100% digital, one of the safest in the market and designed for any type of customer, allowing each client to tailor it according to their preferences.

Total Deposits

Total deposits in September 2021 stood at Ps.766,336 million, a decrease of 0.9% YoY, or Ps.6,648 million. On a sequential basis, total deposits remained flat. Demand deposits reached Ps.563,372 million, increasing 10.5% YoY, or Ps.53,686 million, while time deposits decreased 22.9% YoY, or Ps.60,334 million, as lower interest rates made customers favor short term liquidity and supported by the Bank’s efforts to improve funding mix. In turn, demand deposits increased 2.3%, or Ps.12,836 million, sequentially, while time deposits decreased 6.1% QoQ, or Ps.13,163 million. Deposits from individuals expanded 3.3% YoY, or Ps.8,869 million,

and from corporates contracted 3.1% YoY, or Ps.15,517 million. The Bank continues working on the strategy focused on prioritizing individual deposits and foregoing certain expensive corporate deposits.

Net interest income in 3Q21 totaled Ps.15,684 million, decreasing 2.5% YoY, or Ps.405 million, and 0.5% QoQ, or Ps.86 million.

The 2.5% YoY decrease in net interest income resulted from the combination of:

A 9.3%, or Ps.2,554 million, decrease in interest income, to Ps.24,949 million, which resulted from the combined effect of a 29 basis points decrease in the average interest rate received and a 5.5%, or Ps.79,383 million, decrease in average interest-earning assets; and

ii)

A 18.8%, or Ps.2,149 million, decrease in interest expense, to Ps.9,265 million, stemming from a 44 basis points decrease in the average interest rate paid and a 7.0%, or Ps.89,759 million, decrease in interest-bearing liabilities.

The net interest margin ratio (NIM), calculated using daily average interest-earning assets for 3Q21, stood at 4.64%, compared to 4.50% in 3Q20 and 4.52% in 2Q21. The YoY increase in NIM was principally driven by a lower average interest-earning assets. On a cumulative basis, NIM for 9M21 reached 4.53%, a decrease of 25 basis points from 9M20.

Interest Income

Total average interest earning assets in 3Q21 amounted to Ps.1,351,207 million, decreasing 5.5% YoY, or Ps.79,383 million, mainly driven by decreases of 16.4% YoY, or Ps.77,036 million, in the average amount of investment in securities, 3.7%, or Ps.27,231 million, in the average loan portfolio, and a 56.2%, or Ps.23,889 million, in margin accounts, partly offset by a 43.7% growth, or Ps.26,717 million, in repurchase agreement and by 18.4% increase, or Ps.22,056 million, in funds available.

Non-performing loans as of September 2021 increased 32.4% YoY, or Ps.4,984 million, to Ps.20,376 million, and remained flat on a sequential basis. The YoY increase in non-performing loans was due to increases of 30.8%, or Ps.2,150 million, in mortgage loans, 54.5%, or Ps.1,437 million, in consumer loans (including credit cards) and 24.2%, or Ps.1,397 million, in commercial loans.

Special accounting criteria

Special Accounting Criteria issued for the health contingency caused by the virus SARS CoV-2

The Association of Banks of Mexico (ABM) determined to support the clients of the country's Credit Institutions by issuing various programs due to the pandemic caused by the virus SARS-CoV-2 (COVID-19). However, in order to implement these programs (support programs), it was necessary to request the Mexican National Banking and Securities Commission (Comisión Nacional Bancaria y de Valores, or “CNBV” by its Spanish acronym) to issue various regulatory facilities in the area of accounting registration, loan portfolio classification, regulatory capital, as well as for the report to the Credit Information Societies (SIC by its Spanish acronym)

As a result, on March 26, 2020, the CNBV in cooperation with the Ministry of Finance and Public Credit (SHCP by its Spanish acronym) issued various special temporary accounting measures (Special Accounting Criteria) regarding loans granted to clients in order to guarantee the stability of the Financial System in Mexico in the face of the COVID-19 pandemic. Subsequently, on April 15, 2020, the CNBV issued a series of details and modifications that complement the Special Accounting Criteria.

Banco Santander México implemented various support programs for its clients, which include the partial or total deferment of principal and/or interest payments for 4 months, without interest charges, with respect to the entire amount demanded from borrowers, including accessories. Banco Santander México applied, in accordance with the established requirements, the Special Accounting Criteria on loans granted to clients who decided to join the support programs.

The Special Accounting Criteria apply to mortgage loans with guarantee, revolving and non-revolving loans directed at individuals, such as: automotive loan, personal loans, payroll loan, credit card and microcredit; as well as for commercial loans directed to legal entities or individuals with business activity in its different modalities, including agricultural loans, as long as the loan was classified as a current loan portfolio as of February 28, 2020. In the case of individual or group microcredits, the Special Accounting Criteria were applied to operations classified as a current loan portfolio as of March 31, 2020.

The Special Accounting Criteria are applicable as long as the benefits were implemented by Banco Santander México no later than 120 days after the aforementioned dates, as follows:

Those loans with one-time payment of principal at maturity and periodic payments of interest, as well as loans with one-time payment of principal and interest at maturity, that are renewed or restructured will not be considered as past due loans. To this end, it is required that the new expiration term, which in its case be granted to the borrower, be no more than six months from the date on which it has expired.

Loans with periodic payments of principal and interest, which are subject to restructuring or renewal, may be considered as a current loan portfolio at the time said act is carried out, without the requirements established in Accounting Criterion B-6 being applicable to them "Loan portfolio” issued by the CNBV applicable to the case of merit. The foregoing, subject, among other things, to the fact that the new expiration period, which in its case is granted to the borrower, is not more than six months from the date on which it has expired.

The loans that from the beginning are stipulated to be revolving, which are restructured or renewed within 120 calendar days following February 28, 2020, will not be considered as past due loans in terms of the aforementioned Accounting Criterion B -6 "Loan portfolio". The aforementioned benefit may not exceed six months from the date on which they have expired.

In the agricultural loans and rural sectors, the new maturity term that, where appropriate, is granted to the borrowers due to the application of the Special Accounting Criteria may not be longer than 18 months, according to agricultural production and marketing cycles.

The aforementioned loans are not considered as restructured nor are they reported as past due loans to the SIC.

In the event that the restructuring or renewals included deductions, waivers, bonuses, or discounts on the loan balance that resulted in lower payments for customers, as a mechanism to strengthen their liquidity, the

Earnings Release | 3Q.2021

Banco Santander México

constitution of the allowance for loan losses was deferred, related to the granting of deductions, waivers, bonuses and discounts to customers.

When documenting the new loan conditions, if applicable, there must have been evidence of the agreement between the parties, which could be accredited by email.

Regarding to the modifications to the mortgage loans with guarantee, which could not be updated before a notary public, they will continue to be considered as real guarantees, for the purposes of calculating the provision for loan losses, provided they have been documented by simple contract and, when possible, ratified the signatures before a notary public, obtaining from the borrower most of the documents necessary for the modification of the mortgage, as well as the payment of taxes and duties that may be applicable. The foregoing, with the understanding that extensions of amounts will not be considered.

Those modifications to the original conditions of the loan, in which the risk profiles of the borrower were adjusted, and do not implied a total or partial deferral of principal and / or interests and that did not imply restructuring that show compliance with payment for the total amount due of principal and interests, did not be considered as restructuring, as long as:

These were loans registered as current portfolio as of February 28, 2020.

The contractual procedures for renewal or restructuring ended no later than 120 calendar days after the date indicated above (June 2020).

It was established in said modifications that they will only be applicable for a period that cannot exceed 6 months, with credit institutions being required to maintain the risk profiles originally established for each loan, in accordance with their policies and procedures.

In applying the Special Accounting Criteria, credit institutions were adhered to the following conditions:

Not to make contractual modifications that explicitly or implicitly consider the capitalization of interests, nor the collection of any type of commission derived from the restructuring.

In the case of revolving loans addressed to natural persons, credit lines previously authorized or agreed to as of February 28, 2020 did not been restricted or decreased by more than fifty percent of the unused portion of said lines, or canceled.

In the case of loans to legal entities, credit lines previously authorized or agreed to as of February 28, 2020 did not been restricted or reduced, including the unused part of said lines, or canceled.

Do not request additional guarantees or their substitution in the case of restructuring.

For the purpose of applying the regulatory facilities described above, credit institutions must deliver to the CNBV, the general conditions of the support programs granted to clients, as well as a detailed report on the loans, where the conditions are disaggregated original loan and benefits granted with the Special Accounting Criteria, within ten business days following the end of each month, beginning in March 2020 with the documentation process of the benefits granted.

Finally, on June 29, 2020, the CNBV issued a document where it decided to extend until July 31, 2020 the period of the Special Accounting Criteria, as well as to incorporate into the aforementioned facilities those credit operations in force as of March 31, 2020.

Banco Santander México implemented, from April 1, 2020, various support programs in accordance with the Special Accounting Criteria in order to assist clients that have had a negative effect on their economy derived from the pandemic by COVID-19, as follows:

Credit card

The support consisted of not demanding the minimum payment for 4 months including principal and interest, this was reflected in the client's account statement, since the minimum payment was zero during this period. Once the support is requested, took effect 24 business hours after the request; applying for and obtaining support did not affect the customer's credit history.

Interest was generated at normal rate and these did not be part of the revolving balance, that is, there was no capitalization of interest. The customer was able to make payments at any time to the credit card.

Earnings Release | 3Q.2021

Banco Santander México

It is necessary that the credit card has been in a current situation as of February 28, 2020 and that it has not been issued (formalized) after February 29, 2020. The credit card was disabled 48 hours after the client requested the support, was only enabled for recurring charges (domiciled) that are already registered. Once the support period has ended, the client was able to re-use the credit card.

Personal loan and payroll loan

The loan payments were suspended for a period of 4 months and the original term of the loan was extended for an additional 4 months, maintaining the composition of the payment according to the contracted plan. It was necessary that the loan has been in a current loan portfolio as of February 28, 2020 and that it has been disposed of before that date. The customer was able to make payments during the suspension period.

Automotive loan

The program consisted of not requiring the required payment of the loan for 4 months, extending the original term of the loan while maintaining the contracted payments. It is necessary that the loan has been valid and contracted as of February 28, 2020, and it must not have been classified as a past due portfolio in the last 3 months.

This benefit was reflected to the client from the next payment, once it was confirmed that the client was eligible for support. The customer was able to make advance payments at any time.

Mortgage loan

The support consisted of suspending the payment of the loan for 4 months. This benefit was reflected to the client from the next payment once it was confirmed that the client was eligible for support. There was no impact on the customer's credit history, nor were collection activities carried out.

SME loan - Simple

The loan payment was postponed for up to 4 months, both interest and principal, which means that it was not necessary to make the monthly payment during this period. There was no affectation for the client in the credit bureau (SIC’s), which allowed him to use this liquidity to solve his immediate needs.

The loan line was extended in the same monthly payments for which payment was postponed.

SME loan - Agile

The support consisted of defer the payment of loans for up to 4 months, both interest and principal, without capitalization of interest. This allowed the client to use this liquidity to solve immediate needs, since the minimum payment was not required. The loan conditions were maintained, the only thing that changed was the term that increased up to 4 months, without any affectation in the credit bureau (SIC’s).

As of September 30, 2021, Banco Santander México has 383,965 loans were registered in its different support programs for an amount of Ps. 106,291 million. These loans are segregated as follows:

Banco Santander México considers the Accounting Criteria B-6 "Loan Portfolio" issued by the CNBV regarding to the definition and accounting treatment of the current loan portfolio, past due loan portfolio, restructuring and renewals.

In the same line, Banco Santander México determined the amounts that would have resulted if the Special Accounting Criteria had not been applied as follows:

•

Established the classification of the loans that would have remained in force, as well as those loans that would have been transferred to the past due portfolio if the Special Accounting Criteria had not been applied when making the change in conditions.

•

For those loans that had been transferred to the past due portfolio, it determined the amount of accrued interest whose accumulation had been suspended, and

•

Using the current and past due portfolio classification mentioned in the first point and reducing the amount of the interest whose accumulation had been suspended as indicated in the previous point, the probability of default was recalculated taking into account the past due loan classification as part of the calculation process of the preventive estimate for credit risks.

Special Accounting Criteria issued for meteorological damage

On November 30, 2020, the CNBV issued on a temporary basis, Special Accounting Criteria, applicable to credit institutions, due to the damage caused by meteorological damage that occurred in the southeast of the country, regarding to consumer loans, mortgage loans and commercial loans, for customers who have their domicile or credits whose source of payment is in the affected areas, declared by the Ministry of the Interior or by “Secretaría de Gobernación” or for “Secretaría de Seguridad y Protección Ciudadana” as natural disaster areas.

In general terms, the support consisted in that credit institutions was able to offer their customers the partial or total deferral of principal and / or interest payments for three months, six months in the case of group microcredits, or up to 18 months in the case of directed loans to the agricultural and rural sectors, with the consequent benefit for customers that their loans will continue to be reported as performing loan portfolio to SIC.

The loans adhered to the benefit of the Special Accounting Criteria allowed the credit institutions not to consider them as restructured in accordance with the Accounting Criteria B-6 “Loan Portfolio” issued by the CNBV, which allowed the borrowers to allocate their resources to face the possible damages that they suffered from natural phenomena.

The foregoing will be applicable as long as the credit was classified in accounting as performing loan portfolio in accordance with the Accounting Criteria B-6 "Loan Portfolio" on the date of the claim established in the declaration, and the support implementation process was carried out within 120 calendar days following the date of the claim.

As of September 30, 2021, Banco Santander México has not applied the Special Accounting Criteria, due to the damage caused by meteorological damage that occurred in the southeast of the country.

MFRS C-2, Investment in financial instruments

In order to allow the option of recognizing investments in certain negotiable capital financial instruments that are not traded in the short term, to be valued through other comprehensive income (ORI), the main difference between these investments and the other permanent investments discussed in MFRS C-7, Investments in associates, joint ventures and other permanent investments, it is that the other permanent investments do not intend to sell, so it would be inappropriate to value them at fair value method.

23. Integral Risk Management (unaudited)

23. Integral Risk Management (unaudited)

Risk management is considered by Banco Santander as a competitive element of strategic nature with the purpose of maximizing the value for the stockholder. This management is defined, from a conceptual and organizational sense, as a comprehensive management of the different risks (market risk, liquidity risk, credit risk, counterparty risk, operative risk, legal risk and technological risk) assumed by Banco Santander for the development of its activities. The management of the risk inherent to transactions is essential for understanding and determining the behavior of the financial condition of Banco Santander and the creation of long-term value.

In order to comply with the provisions regarding the Comprehensive Risk management applicable to credit institutions, issued by the National Banking and Exchange Commission, the Board of Directors agreed to create the Comprehensive Risk Management Committee of Banco Santander, to work pursuant to the rules set by such regulations. This Committee gathers every month and verifies that the transactions are according to the objectives, policies and procedures approved by the Board of Directors for the Comprehensive Risk Management.

The Comprehensive Risk management Committee delegates in the Comprehensive Risk Management Unit the responsibility for the implementation of procedures for the measure, administration and control of risks according to the applicable policies; such Unit has the faculty to authorize amounts greater than the stipulated limits and in such cases, the Board of Directors shall be informed on such deviations.

Market Risk

The Market Risk Management department of the Comprehensive Risk management Unit is responsible for recommending the policies on market risk management of Banco Santander, and to establish the parameters for risk measuring, and to provide reports, analysis and assessments to the senior management, to the Comprehensive Risk management Committee and to the Board of Directors.

The market risk management is to identify measure, monitor and control risks arising from fluctuations in interest rates, exchange rates, prices and other market risk factors in currency, money, capital and derivative markets that are exposed the positions that belong to Banco Santander.

The market risk measurement quantifies the potential variation in the value of the positions as a consequence of changes in the market risk factors.

Earnings Release | 3Q.2021

Banco Santander México

Depending on the nature of the activities of each business unit, debt and capital instruments are registered as securities for trade, securities available for sale and or securities held to maturity. The main characteristic that identifies securities available for sale is their permanent nature and they are managed as an structural part of the balance sheet. Banco Santander has established provisions that all securities available for sale must fulfill, as well as adequate controls for the compliance of such provisions.

Whenever significant risks are identified, they are measured and limits are allocated in order to assure an adequate control. Global measurement of risk is carried out via a combination of the methodology applied to Portfolios for Trade and to the management of Assets and Liabilities.

Trading Books

In order to measure the risk in a global approach, the methodology of Value at Risk (“VaR”) is used. VaR is defined as the statistical estimate of the potential loss of value of a given position, during certain period and at certain confidence level. VaR provides a universal measure of the level of exposure of the different risk portfolios; it allows the comparison of the risk level assumed in different securities and markets and expresses the level of each portfolio through a unique figure in economic units.

VaR is calculated via historical simulation, with a 521 working-days window (520 percentage changes) and a one-day horizon. The calculation is performed from a series of simulated gains and losses with 1% percentile at constant pesos and with pesos decreasing on an exponential basis, with a decrease factor that is reviewed on annual basis, the most conservative measure is the one to be reported. A confidence level of 99% is assumed.

Note that the historical simulation model is limiting to assume that the recent past represent the near future.

The Value at Risk as of the end of third quarter of 2021 (unaudited) amounted to:

Bank
	VaR (Thousands of Mexican pesos)	%
Trading Desks	34,827.68	0.02%
Market Making	28,465.50	0.02%
Proprietary Trading	18,167.06	0.01%

Risk factor
Interest rate	36,442.54	0.02%
Foreign exchange	12,725.48	0.01%
Equity	860.47	0.00%
* % of VaR with respect to Net Capital

The Value at Risk for the average the third quarter of 2021 (unaudited) amounted to:

Bank
	VaR (Thousands of pesos)	%
Trading Desks	48,039.26	0.03%
Market Making	36,635.25	0.02%
Proprietary Trading	17,599.97	0.01%

Risk factor
Interest rate	48,523.29	0.03%
Foreign exchange	9,086.47	0.01%
Equity	2,885.55	0.00%
* % of VaR with respect to Net Capital

Likewise, monthly simulations of gains or losses of portfolios are carried out by revaluating such portfolios under different scenarios (Stress Test). Such estimates are generated using two different methods:

Applying to risk factors the percentage changes observed in certain periods including relevant market turbulences.

Earnings Release | 3Q.2021

Banco Santander México

Applying to risk factors changes that depend on the volatility of each risk factor.

On a monthly basis “back testing” is carried out to compare daily gains and losses that would have been observed is the same positions had been maintained, taking into account only the change in value at risk in order to be able to fine tune the models. Even though these reports are prepared on a monthly basis, they include daily tests.

Assets and Liabilities Management

Commercial banking activities of Banco Santander generate important balance sheet amounts. The Assets and Liabilities Committee (“ALCO”) is responsible for determining the guidelines for the management of financial margin risk, net worth value and liquidity that must be followed by the different commercial portfolios. Pursuant to this approach, the General Direction of Finances has the responsibility to execute the strategies defined by the Assets and Liabilities Committee in order to modify the risk profile of the commercial portfolio by following the corresponding policies. Compliance with information requirements for interest rate, Exchange rate and liquidity risks is fundamental.

As part of the financial management of Banco Santander, sensitivity to Net Interest Income (“NIM”) and Market Value of Equity (“MVE”) of the different balance sheet items is analyzed in comparison to variations in interest rates. This sensitivity is derived from the difference between maturity dates of assets and liabilities and the dates interest rates are modified. The analysis is performed from the classification of each item sensitive to interest rate throughout time, according to their repayment, maturity or contractual modification of the applicable interest rate.

	Sensitivity NIM				Sensitivity MVE
Bank	Jul-21	Aug-21	Sep-21	Average	Jul-21	Aug-21	Sep-21	Average
Balance MXN GAP	36%	38%	41%	38%	14%	14%	26%	18%
Scenario	(100) bp	(100) bp	(100) bp	N/A	+100 bp	+100 bp	+100 bp	N/A
Balance USD GAP	19%	23%	23%	22%	32%	31%	34%	32%
Scenario	(25) bp	(25) bp	(25) bp	N/A	(25) bp	(25) bp	(25) bp	N/A

Using simulation techniques, the predictable change of the net interest income and the market value of equity are measured in different interest rate scenarios, and their sensitivity under extreme movement of such scenarios, as of the end of the third quarter of 2021:

	Sensitivity NIM				Sensitivity MVE
Bank	Scenario	Total	Derivatives	Non Derivatives	Scenario	Total	Derivatives	Non Derivatives
Balance MXN GAP	(100) bp	(614 )	(775)	161	+100 bp	(1,109)	1,011	(2,120)
Balance USD GAP	(25) bp	(236)	7	(243)	(25) bp	(1,045)	(737)	(308)

The Assets and Liabilities Committee adopts investment and hedging strategies in order to maintain such sensitivities within the target range.

Limits

Limits are used to control global risk of the financial group derived from each portfolio and books. The structure of limits is used to control exposures and to establish the total risk authorized to business units. These limits are established for VaR, Loss alert, maximum loss, equivalent volume of interest rate, delta equivalent in equity, open foreign currency positions, sensitivity of net interest income and sensitivity of market value of equity.

Liquidity Risk

Liquidity risk is related to the ability of Banco Santander to finance acquired commitments at reasonable market prices, as well as to fulfill business plans with stable financing sources. Risk factors may be external (liquidity crisis) and internal due to excessive concentration of maturities.

Banco Santander carries out a coordinated management of maturities of assets and liabilities, and oversees the maximum timing difference profiles. This monitoring is based in the analysis of maturities of assets and liabilities, both contractual and managerial. Banco Santander realizes a control for the maintenance of a sufficient quantity of liquid assets to guarantee a horizon of survival during a minimum of days facing a scene of stress of liquidity without resorting to additional financing sources. The risk of Liquidity is limited in terms of a minimal period of days established for local, foreign and consolidated currencies. It is necessary to indicate that in the current quarter incidents have not been had in the metrics.

Credit Risk

Management of credit risk of Grupo Financiero Santander is developed differently for the different segments of clients along the three phases of the credit process: acceptance, follow-up and recovery.

From a global perspective, management of credit risk in Grupo Financiero Santander is responsible for the identification, measurement, integration and assessment of the aggregated risk and the profitability according to such risk; with the purpose of oversee the levels of risk concentration and to adapt them to the limits and objectives previously established.

Risks receiving an individual treatment (risks with companies, Grupo Financiero Santander and financial entities) are identified and taken apart from those other risk that are managed in standardized manner (consumer and mortgages credits to individuals, loans to businesses and small enterprises).

Risks managed on individual basis are subject to a solvency or rating system with a related probability of failure that allows the measuring of the risk for each client and for each transaction from the beginning. The assessment of the client, after analyzing other relevant risk factors in different areas, is adjusted according to the special characteristics of the transaction (guarantee, term, etc,).

Standardized risks require, due to their special characteristics (great number of transactions for relatively low amounts), a different management that allows an efficient process and effective use of resources, so automated decision tools are used (expert and credit scoring systems).

Management of loans to companies is complemented, during the follow-up phase, with the so called “system of special monitoring” that determines the policy to be followed in the management of the risks with companies or groups rated within such category. Different situations of levels of monitoring are identified and generate different actions. A special monitoring grade is given in the case of alert signals, systematic reviews, or specific initiatives promoted by the Risks Department or Internal Audit.

Recovery Units constitute a critical element in the management of irregular risk, in order to minimize the final loss for Grupo Financiero Santander. These units are responsible for a specialized management of the risk from the moment they are classified as irregular risk loans (defaulting payment).

Grupo Financiero Santander has carried out a policy for the selective growth of risk and a strict treatment of late payments and the creation of the corresponding provisions, based in the prudent criteria defined by the Group.

Probability of Default and Expected Losses

Pursuant to the provisions on Comprehensive Risk Management included in the general regulations applicable to credit institutions, as part of the credit risk management, credit institutions must determine the probability of default.

The system allows the calculation of the probability for the different loans portfolios.

The probability of failure is for “No Retail” portfolios. It is determined via the fine tune of the ratings of clients in a given moment, based in the Monthly Default Rates observed during a period of five years. Such Default Rates are adjusted to an economic cycle of ten years. For “Retail” portfolios, the standard default probabilities set by the Basel Convention are used.

Once the probability of default is determined, the parameters of “severity of Loss” (“LGD”) and “Exposure at Default” (“EAD”) stipulated in Basel, are taken into consideration.

Once the abovementioned factors are obtained, the Expected Loss (“PE”) is calculated as follows:

Expected Loss = Probability of Default x Severity of Loss x Exposure at Default

i.e.: PE = PD * LGD * EAD

Counterparty Risk

Within the credit risk, there is a concept that, due to its specific characteristics, it requires a special management: the Counterparty Credit Risk.

Counterparty Credit Risk (CCR) is defined as the risk that may arise from total or partial breach of the financial obligations contracted with the entity. It is a bilateral credit risk, as it may affect both parties of the transaction, and it is uncertain, since it is conditioned by the behaviour of markets, which are volatile.

The financial securities that generates this exposure are the financial derivatives, repurchase agreements (REPOs) and security lending. The management and control of this type of credit risk is carried out by a specific team with an organizational structure independent from the business teams.

For the control of the counterparty credit lines, the Equivalent Credit Risk (REC) is used. The REC is the metric that represents the peak exposure or the highest potential future exposure value at a specific time interval and it can be obtained in the following ways:

Gross REC: it measures the exposure without considering netting and collateral agreements. It´s obtained at a transaction level and at other levels of aggregation.

Net REC: it measures the exposure considering netting and collateral agreements and personal or financial guarantees. It´s calculated at a netting agreement level and at other levels of aggregation.

In addition to the Counterparty Risk, there is the issuing risk, which is generated by the acquisition and / or direct disposal of public and private instruments of authorized securities and the Settlement Risk, also known for Herstatt risk for FX trading, is the risk that is generated in the exchange of securities when one of the parties fails to deliver the securities/currency/cash, committed by contract, having received the amount from the other party.

The control of Counterparty Risk is performed in a daily basis using the Interactive Risk Integrated System (IRIS), which allows to know the credit line availability for all the counterparties, for any of the instruments already mentioned and term.

For the process of control for this risk, Financial Risk Division oversees on a daily basis the compliance with the limits on counterparty credit risks by product, term and other conditions stipulated in the authorization for financial markets. Likewise, it is the responsible for communicating on a daily bases, the limits, consumptions and any incurred deviation or excess.

On a monthly basis, a report is presented to the Risk Management Committee, with respect to the limits to Counterparty Credit Risks, Issuer Risks and current consumptions. In addition, on a monthly basis, a report is presented to the Global Banking Credit Committee and Retail Credit Committee with respect to incurred excesses and transactions with non-authorized customers. Also, in a monthly basis, is presented to the Risk Management Committee the present value of the expected loss for the actual portfolio of derivatives and repos in a base scenario and two other stressed scenarios (LGD and PD).

Currently, Banco Santander has lines of counterparty credit risk with the following segments: Mexican Sovereign Risk and Domestic Development Banking, Foreign Financial Institutions, Mexican Financial Institutions, Corporations, Companies Banking-SGC, Institutional Banking, Large Enterprises Unit and Project Finance.

The segments of Mexican Financial Institutions and Foreign Financial Institutions are very active counterparties with whom Banco Santander has current positions of financial instruments with Counterparty Credit Risk. It is important to mention that Equivalent Credit Risk is mitigated by netting agreements (ISDA-CMOF) and, in some cases, by collateral agreements (CSA-CGAR) or revaluation agreements with counterparties.

Respect to total collateral received for derivatives transactions as of the end of the 3Q of 2021:

Warranty
	Average
Cash	68.20%
Debt issued by the Mexican Government	13.96%
Debt issued by Sovereigns other than the Mexico	17.84%

Note: In the event that the credit rating of Banco Santander is lowered, there would be no impact on the amount of real guarantees that the Institution would have to provide, because the guarantee contracts with a threshold greater than 0 are unilateral in favor of the Institution.

In respect to collateral management in derivatives transactions, counterparty’s positions are valuated according to the frequency established at each collateral agreement. In addition, all credit risk parameters, established at each collateral agreement are considered to obtain the amount of collateral to be delivered or to be received from the counterparty. These

Earnings Release | 3Q.2021

Banco Santander México

amounts, margin calls, will be requested from the counterparty which has the right to receive the collateral, according to the frequency established at the collateral agreement. The counterparty which receives the margin call, has the right to analyze the valuation and it could result on discrepancies to solve. There are two types of margins for derivatives:

Variation Margin: it refers to collateral delivered by a counterparty to another counterparty in order to meet its obligations under one or more transactions between the parties, as a result of a change in the value of such obligations since the last time those collaterals were delivered.

Initial Margin: it refers to the collateral received by a counterparty to cover its current and future exposure in the interval between the last receipt of margin and the settlement of positions or the coverage of market risk after a default by the other counterparty.

The control of wrong-way risk is also performed by the counterparty credit risk team. This risk occurs when the "exposure to a counterparty is adversely correlated with the credit quality of that counterparty", in short it arises when default risk and credit exposure increase together. In Banco Santander (Mexico) the deals with wrong-way risk receive a special treatment, they are not included in the netting set and must have an independent CSA, so the exposure is limited.

Legal Risk

Legal Risk is defined as the potential loss due to the failure to comply with the applicable legal and administrative regulations, the issue of administrative and judicial resolutions against Banco Santander and the application of fines, with respect to the transactions carried out by Banco Santander.

Pursuant to the provisions regarding the Comprehensive Risk Management, the following activities are performed: a) Establishment of policies and procedures for analyzing the legal validity and the proper execution of the legal acts. b) estimates of the amount of potential losses derived from judicial or administrative orders against Banco Santander and the possible application of fines c) Analysis of the legal acts governed by a legal system different to the Mexican laws, d) communication to directors and employees on the legal and administrative regulations applicable to transactions and e) the performance, at least on annual basis, of internal legal audits.

Operational Risk

Operational risk is defined as the risk of loss resulting from inadequate or failed internal processes, people and systems or from external events.

The main objective is to avoid or reduce the impact of Operational Risk, through the identification, monitoring and control of the factors that trigger the events of potential loss. Therefore, it also requires to establish policies and procedures to operate under the risk exposure that the Bank is willing to accept.

The sound management of risk involves mainly the heads of each Business Unit on the management tools and results; as well as a continuous training to the staff. The pillars on which the operational risks are managed are:

a) Strategic planning and budget: Required activities to define the operational risk profile for Banco Santander México; this includes:

Risk appetite, defined as the level of risk that the Bank is willing to accept

Loss annual budget, ensuring the overview of real losses according to the budget and the deviations, challenging the controls and extenuation measures.

b) Identify, measure and evaluation of the Operational risk; identify risks and the factors that trigger them in the Bank, and estimate the qualitative or/and quantitative impact.

c) Monitoring; The Overview and monitoring of operational risk goal for periodic analysis of available information of risk (type and level) during the normal development of the activities.

d) Extenuation (Mitigation); once the Operational Risk has been assessed, it is required to establish actions to avoid the risk or to mitigate the impact for risk that materialize, develop a cost-benefit study and indicators should be implemented to help us evaluate the effectiveness of these actions.

e) Reporting; the Operational Risk profile and performance of the Operational Risk environment is presented on a regular basis in Bank Committees.

Banco Santander México had an average monthly loss of Ps.59 million for operational risk in general to the first quarter of 2021.

Since December 2016, Banco Santander México applies the Alternate Standard Approach (ASA) for operational risk capital requirements.

Technological Risk

Technological risk is defined as the potential loss due to damages, discontinuation, alterations or failures derived from the use or dependence on hardware, software, systems, applications, networks and any other data channel distribution for the provision of banking services to the clients of Banco Santander.

Banco Santander México has adopted a corporate model for the management of technological risk (which includes cyber risks), integrated into the service and support processes of the technological areas, to identify, evaluate, monitor, control, mitigate and report the technological risks to which the operation is exposed. This model allows the establishment of control measures to reduce the probability of risks materializing or, minimize the impact of those risks.

Processes and levels of authorization

Pursuant to internal regulations, all the products and services traded by Banco Santander are approved by the “Comité de Comercialización” and by the “Comité Corporativo de Comercialización”. Those products or services that are modified or extended with respect to their original approval must be approved by the “Comité de Comercialización” and, depending of their relevance, the “Comité Corporaivo de Comercialización” must approve them too.

All areas taking part in the operation of the product or service, depending on the nature of such product or service, as well as the areas responsible for their accounting registration, legal formalization, fiscal treatment, risk assessment, etc. are present in the Committee. All approvals shall be unanimous as there are no authorizations approved by majority of votes. In addition to the Committee’s approval, there are products that require authorizations from local authorities, and therefore, the Committee’s approvals are subject to the authorizations issued by the competent authorities in each case.

General description of the valuation techniques

Derivative financial securities are valued at reasonable value, according to the accounting rules established in the Circular Letter for Credit Institutions issued by the National Banking and Exchange Commission, in Principle B-5 “Derivative Financial Instruments and hedging Transactions” and the provisions in Principle A-2 “Application of specific rules”, and the provisions in the specific rule included in Bulletin C-10 of the Financial Information Rules.

A. Methodology of Valuation

Trading purposes

Organized Markets

Valuation is made at the corresponding closing market price. Prices are provided by the supplier of prices.

Over-the-Counter Markets

Derivative financial instruments with optionality.

In the majority of the cases, a general form of the Black & Scholes model is used. Such model assumes that the underlying product follows a lognormal distribution. For exotic products or when payment depends on the trajectory of any market variable, Monte Carlo simulations are used. In this case, it is assumed that logarithms of the different variables follow a multi-varied normal distribution.

ii)

Derivative financial instruments with no optionality.

The valuation technique is to obtain the present value of the estimated future flows.

In all cases, Banco Santander carries out the valuation of its positions and registers the corresponding value. In some cases, a different calculation agent is designated, and such calculation agent may be the counterparty or a quarter party.

Hedging purposes

In the performance of its commercial banking activities, Banco Santander has tried to cover the evolution of the financial margin of structured portfolios that are exposed to adverse movements in interest rates. The ALCO, the body responsible for the management of long-term assets and liabilities, has constituted the portfolio via which the Banco Santander achieves such hedge.

An accounting hedge is defined as a transaction that complies with the following conditions:

A hedge relationship is designated and documented from the beginning in an individual file, where its objective and strategy is established.

The hedge is effective for the compensation of variations in the reasonable value or in the cash flows attributed to such risk, according to the risk management documented at the beginning.

The Management of Banco Santander performs derivative transactions for hedging purposes with swaps.

Derivatives for hedging purposes are valued at market value, and the effect is recognized depending on the type of accounting hedge, pursuant to the following:

In the case of fair value hedges, they are valued at market value for the risk covered, the primary position and the hedging derivative instrument, and the net effect is registered in the statement of income of the corresponding period.

In the case of cash flow hedges, the hedging derivative instrument is valued at market value. The effective portion of the hedge is registered in the comprehensive income account, within the stockholders’ equity, and the ineffective portion is registered in the statement of income.

Banco Santander ceases the recording of hedges at the maturity date of the derivative, or when such derivative is sold, cancelled or exercised; when the derivative does not reach a high efficiency in compensating the changes in the reasonable value or the cash flows of the covered item, or when Banco Santander decides to cancel the hedge.

It shall be fully evidenced that the hedge fulfills the objective for which derivatives were contracted for. This effectiveness requirement assumes that the hedge must comply with a maximum range of deviation with respect to the initial objective of 80% to 125%.

In order to demonstrate the efficacy of hedges, two tests are to be carried out:

Forward-looking Test: it is demonstrated that, in the future, the hedge will be within the aforementioned range of deviation.

Retrospective Test: This test reviews if, in the past, from its initial date to now, the hedge has been maintained within the allowed range of deviation.

In the cases of Fair Value Hedges and the Cash Flow Hedges, they are retrospective and forward-looking efficient and within the allowed maximum range of deviation.

B. Reference Variables

The most relevant reference variables are:

Exchange Rates

Interest Rates

Equity

Baskets of equities and stock indexes.

C. Frequency of valuation

Derivative financial instruments for trading and hedging purposes are valued on a daily basis.

Management of internal and external sources of liquidity that may be used for the compliance of requirements related to derivative financial instruments.

Resources are obtained via the National and International Treasury departments.

Changes in exposure to identified risks, contingencies and events, known or expected, in derivative financial instruments.

At the end of the quarter of 2016, Banco Santander has no situation or contingency such as changes in the value of the underlying asset or the reference variables, that may cause the use of the derivative financial instruments to be different to their original intended use, a significant change in their scheme or the total or partial loss of the hedge, requiring the Issuer to assume new obligations, commitments or variations in its cash flow or affecting its liquidity (day trade calls), nor contingencies or events known or expected by the Management that may affect future reports.

The sensitivities are detailed below according to each risk factor and associated historical consumption of the trading book.

The management strategy of the organization is integrated with security positions and derivatives. The latter are used largely to mitigate the market risk of the second. In view of the above, the sensitivities or exposures as described below are both types of instruments considered as a whole.

1. Sensitivity to risk factor “Equity (“Delta EQ”)

The EQ Delta shows the change in the portfolio's value in relation to changes in the prices of equities.

The EQ Delta calculated for the case of derivative financial instruments considered the relative change of 1% in the prices of the underlying assets in equities, in the case of equities, this considers the relative variation of 1% of market price title.

2. Sensitivity to risk factor “Foreign Exchange”, (“Delta FX”)

3. Sensitivity to risk factor “Volatility” (“Vega”)

Vega sensitivity is the measure resulting from changes in the volatility of the underlying asset (the reference asset). Vega risk is the risk that a change in the volatility of the underlying asset value, that results in a change in the market value of the derivative.

The calculation of Vega sensitivity, considers the absolute change of 1% in the volatility of the underlying asset value.

4. Sensitivity to risk factors “Interest Rate” (“Rho”)

This sensitivity quantifies the change in value of financial instruments for the trading portfolio in the face of a parallel increase in the interest rate curves of a basis point.

The table below presents the sensitivities described above corresponding to the position of the trading portfolio, as of the end of the third quarter of 2021:

Stress Test for Derivative Financial Instruments

The following are various stress test scenarios considering various scenarios calculated for the trading portfolio of Banco Santander.

Probable scenario

This scenario was defined based in the movements derived from a standard deviation, with respect to risk factors that have an influence over the valuation of financial instruments. Specifically:

Risk factors of Interest Rate (“IR”), volatility (“Vol”) and rate of Exchange (“FX”) were incremented in a standard deviation.

Risk factors with respect to stock market (“EQ”) were decreased in a standard deviation.

Possible scenario

Under this scenario, as requested in the official letter, risk factors were modified in 25%. Specifically:

Risk factors: IR, Vol and FX were multiplied by 1.25 that means, they were incremented in 25%.

Risk factor EQ was multiplied by 0.75 that means, it was decreased in 25%.

Remote scenario

Under this scenario, as requested in the official letter, risk factors were modified in 50%. Specifically:

Risk factors IR, Vol and FX are multiplied by 1.50, that is, they were incremented in 50%.

Risk factor EQ was multiplied by 0.5, that is, it was decreased a 50%.

Effect in the Income Statement

The following table shows the possible income (loss) for the trading portfolio of Banco Santander, in millions of Mexican pesos for each stress scenario, as of the end of the third quarter of 2021:

The Bank has no concentration limits under guarantees received by market operations, as they are mainly composed of government securities and cash.

Exposure to liquidity risk and funding needs of the institution, taking into account the legal, regulatory and operational constraints on liquidity transfers.

· Liquidity risk is associated with our capacity to finance the commitments we undertake at reasonable prices, as well as maintaining our ability to carry out our business plans using stable financing sources. Factors that influence liquidity risk may be external, such as a liquidity crisis, or internal, such as an excessive concentration of maturities.

· The measures used to control liquidity risk in balance sheet management are the liquidity gap, liquidity ratios, stress scenarios and liquidity horizons.

· The liquidity horizons metric has been defined to ensure that the Group has sufficient liquid assets to comply with its requirements during a certain period of time, given different stress scenarios. The Group set a 90-day survival horizon for local currency and consolidated balance and a 30-day survival horizon for foreign currency. During the 2Q21, the balance remained above the established limits, and therefore we maintained a sufficient liquidity buffer.
