Evolution of the Modern Peso
The modern Mexican peso was introduced in 1993, replacing the previous peso at a rate of 1,000 to 1 to curb high inflation and restore confidence in the currency.

Monetary policy decisions influence interest rates, inflation expectations, and the strength of the peso over time. A credible central bank framework helps reduce uncertainty for businesses engaged in cross-border trade and investment.
