A short history of the Mexican Peso
The peso is the direct descendant of the Spanish colonial real — the original global trade coin — and Mexico has issued its own since 1823. The 1980s debt and inflation crises ended in 1993 with the Nuevo Peso, which removed three zeros; the Nuevo was dropped from the name in 1996. The 1994 Tequila crisis then forced the peso to float, and it has been freely traded ever since.
Today the Mexican peso is the most traded currency in Latin America and one of the top emerging-market pairs globally, with a new tailwind: nearshoring, as factories relocate closer to the US market.
What moves the MXN exchange rate
The peso trades on its own central bank and on America's economy at the same time — a double exposure no other currency has quite so strongly.
- Banxico policy: an independent, orthodox inflation targeter, often holding rates higher than the Fed for long stretches
- The US economy: about 80% of Mexican exports go north, and US recessions hit the peso first
- Remittances: over $60 billion a year flows in from the US — one of the world's largest corridors and a steady dollar supply
- Risk appetite and carry: high Mexican rates make the peso a favorite carry-trade currency — strong in calm times, sharp drops in panics
The Peso in practice
Travelers find Mexico comfortably card-friendly in cities and resorts, with cash still essential at markets, taxis and small eateries — the OXXO convenience-store cash culture is real. ATMs are widespread; use bank-affiliated ones, decline the machine's conversion offer, and note tips of 10–15% are customary.
For remittances, the US–Mexico corridor is the largest on earth and among the cheapest — competition has pushed fees to a few percent or less. Beyond the Americas, compare providers carefully; the spread differences are significant.

Frequently asked questions
Why is USD/MXN so volatile?
The peso combines emerging-market risk with a huge carry trade: global funds borrow cheap currencies and hold pesos for the rate gap. When fear spikes, those positions unwind fast and the peso falls sharply — the reverse is true in calm markets.
What was the 1993 revaluation?
After the 1980s inflation crises, Mexico replaced 1,000 old pesos with 1 new peso (the Nuevo Peso) in 1993. Today's peso equals one thousand pre-1993 pesos.
Should I use cash or card in Mexico?
Both: cards work in cities, malls and resorts, but carry pesos in cash for markets, street food, taxis and small towns. Pay in pesos, never accept the terminal's offer to charge in dollars.
