Dollar Reaches 18.81 Pesos in Mexico, Highest Since August 2025

The dollar in Mexico rose to 18.8148 pesos, according to the FIX exchange rate that Banco de México (Banxico) determined on Thursday, October 29, 2026. This is the highest level since August 4, 2025, when the FIX was 18.8783, and the highest so far in 2026.

Why it matters: when the dollar rises against the peso, the reference rate is equivalent to more pesos for each dollar sent to Mexico. This can be reflected in what a family receives, although the final amount depends on the rate and commissions of each money transfer company.
