The National Banking and Securities Commission of Mexico has identified some banks considered to be systemically important, whose potential failure could affect the stability of the financial system or the economy of the country. These institutions are required to establish a capital conservation buffer in addition to the minimum capital adequacy ratio required.
As of December 2024, it was determined that Banco Inbursa, HSBC Mexico, Banco Citi Mexico, and Scotiabank are part of the first level of systemic importance. These banks must comply with the obligation to establish a capital conservation buffer of 0.60 percentage points. In the second level are Banamex and Banorte, with an additional buffer of 0.90 percentage points and an additional capital of 1.20 and 1.50 percentage points, respectively.
The CNBV revealed that as of February 2025, the Multiple Banking Capitalization Index was at 19.93%, with a Basic Capital Ratio of 17.87% and a Core Capital Ratio of 16.42%. All banks in the country were placed in Category I of early warnings, demonstrating that they are sufficiently capitalized to face unexpected loss scenarios.
A total of eight banks make up the group of institutions considered to be of local systemic importance, including Citi Mexico after its separation from Banamex last year. The Governing Board of the regulator assessed the degree of systemic importance of all multiple banking institutions, placing Banco Santander in category three and BBVA Mexico in category four.
