The Central Bank of Mexico opened a public consultation on draft amendments to its rules governing open market operations, seeking to give banks greater flexibility to obtain central bank funding, support more efficient liquidity management in the money market, and strengthen monetary policy implementation. The proposal would amend the provisions contained in Circular 3/2012 covering credit institutions, regulated multiple purpose financial companies with equity links to credit institutions, and the Financiera Nacional de Desarrollo Agropecuario, Rural, Forestal y Pesquero. The main proposed change is an expansion of eligible collateral for open market operations to include foreign-currency-denominated Federal Government debt (Bonos UMS), debt issued by development banks, and United States Treasury securities. Public comments may be submitted only via the Central Bank of Mexico’s online consultation portal until 18:00 on 28 October 2025.
