Mexican AXI

Mexican AXI establishes the across-the-curve credit spread indices (MXAXI) tailored for the Mexican market and the Financial Condition Credit Spread Index (MXFXI), accounting for specific features of the Mexican corporate bond market.

These indices capture the average funding expenses incurred by major Mexican commercial banks and corporations, respectively, and are to be used as benchmarks for credit pricing, risk management, and assessing the financial system’s health. Following the approach outlined by Berndt, Duffie, and Zhu (2023), we formulate the long-term credit spread indices by amalgamating credit spreads from bonds with varying maturities issued by Mexican commercial banks.

This paper establishes the across-the-curve credit spread indices (MXAXI) tailored for the Mexican market and the Financial Condition Credit Spread Index (MXFXI), accounting for specific features of the Mexican corporate bond market. These indices capture the average funding expenses incurred by major Mexican commercial banks and corporations, respectively, and are to be used as benchmarks for credit pricing, risk management, and assessing the financial system’s health. Following the approach outlined by Berndt, Duffie, and Zhu (2023), we formulate the long-term credit spread indices by amalgamating credit spreads from bonds with varying maturities issued by Mexican commercial banks. The weights assigned to these spreads account for issuance volumes. The short-term MXAXI index is computed from a mix of short-term funding instruments used by the banking sector in Mexico; the result is compared with the spread of government bonds and the alternative TIIE-28 rate published by Banco de Mexico. This comparison is pertinent as clearing houses and dealers have been preparing to transition away from the 28-plus day TIIE, following a directive from the Mexican central bank banning its use in swap trades starting in 2025.

Julio Cacho, co-author of the Mexican AXI paper said, “The introduction of MXAXI and MXFXI alongside the Overnight TIIE rate offers significant advantages for Mexico’s financial system. By providing dynamic spreads that reflect shifts in banks’ funding costs, these indices help reduce mismatches during market volatility. Furthermore, they enhance the alignment of borrowing and lending rates, encouraging greater access to credit. The use of these indices in derivatives also opens new opportunities for market participants to engage with Mexico’s credit conditions, supporting the overall stability and growth of the local credit markets.”

Mexico boasts one of the most developed bond markets in Latin America, with outstanding domestic debt securities amounting to USD $677 billion, trailing only Brazil. The country enjoys macroeconomic stability, attributable to sound public finances, disciplined monetary policy, and the robustness of banks under a modern regulatory and supervisory framework. These factors, along with improved financing conditions, have facilitated a structural transformation of the Mexican economy and its financial markets (Sidaoui and Ramos-Francia, 2008).

Jose Carlos, co-author the Mexican AXI paper said, “The transition away from LIBOR is a critical step for aligning Mexico’s financial markets with global standards. By adopting the Overnight TIIE and innovative benchmarks like the MXAXI and MXFXI indices, Mexico ensures a more transparent, replicable, and stable framework for its money and derivatives markets. This proactive shift underscores the commitment of Mexican authorities, led by the Bank of Mexico, to fostering financial stability and staying ahead in global financial reforms.”

We identify three core benefits of using MXAXI and MXFXI in conjunction with the Overnight TIIE rate, which is endorsed by the Working Group on Alternative Reference Rates in Mexico and promoted by the Mexican Central Bank as a reference rate: (i) Banks could mitigate mismatches between lenders’ assets and liabilities during market stress by using these indices as dynamic spreads reflecting changes in banks’ cost of funds over forward-looking term periods. (ii) In commercial lending applications, such as revolving lines of credit offered by Mexican banks and other financial institutions to non-financial corporations, these indices will enable closer alignment of borrowing and lending rates, increasing the willingness to extend credit throughout the business cycle. (iii) Derivatives referencing MXAXI and MXFXI could be utilized by hedge funds to take positions on credit conditions in Mexico, thereby benefiting local credit markets.
