Banxico sets official peso exchange rate at 17.9218/USD

Banco de México (Banxico) announced the official peso exchange rate (FIX) for March 13, 2026, at 17.9218 MXN/USD, reflecting its ongoing efforts to maintain price stability and support economic confidence. The FIX rate is calculated as the average of wholesale foreign exchange market quotes for operations payable within 48 hours, as outlined in Banxico's regulatory framework. This rate becomes effective following its publication in the Diario Oficial de la Federación, one business day after determination.

The exchange rate serves as a critical benchmark for settling liabilities denominated in U.S. dollars within Mexico, influencing trade, investment, and financial transactions. Banxico's methodology for determining the FIX rate emphasizes transparency and market alignment, ensuring it represents interbank and institutional foreign exchange operations. The central bank's primary mandate—sustaining low and stable inflation— remains central to its monetary policy decisions, including exchange rate management.

Historical context shows the FIX rate has evolved through various regimes since 1960, adapting to economic conditions and market dynamics. As of November 1, 2021, Banxico revised its methodology for calculating the closing exchange rate, further refining its approach to currency management. Investors and financial institutions closely monitor the FIX rate for its implications on cross-border transactions and inflationary pressures.

For the latest updates, stakeholders are directed to Banxico's official publications and the Diario Oficial de la Federación.
