The Central Bank of Mexico announced an extraordinary auction on Oct. 29, 2026, to purchase up to MXN 50 billion in nominal value of Federal Government Development Bonds paying variable interest rates (Bondes F). The operation aims solely to provide short-term liquidity to the financial system and keep the overnight interbank funding rate close to the target set by the bank’s Governing Board. The auction will cover 10 bond issues with remaining maturities ranging from 699 to 2,183 days, using a single price format. The MXN 50 billion ceiling applies across all eligible issues. Bondes F pay interest linked to the overnight funding rate (TIIE de Fondeo), which reduces their price sensitivity to interest rate movements. Settlement is scheduled for Oct. 30, 2026.
