Overview

The Mexican Peso (MXN) is the official currency of Mexico and the most traded currency in Latin America. It consistently ranks among the top fifteen most traded currencies globally by daily foreign exchange volume. Issued by the Bank of Mexico (Banxico), the peso floats freely and is one of the most liquid emerging market currencies.

Mexico's economy is deeply integrated with that of the United States — its northern neighbour and overwhelmingly dominant trading partner, accounting for roughly 80% of Mexican exports. This relationship, formalised through NAFTA and its successor USMCA, means the MXN is highly sensitive to developments in the US economy, US interest rate policy, and bilateral trade dynamics. Remittances from Mexicans living in the US are also a major source of dollar inflows, exceeding $60 billion per year.

History

The Mexican Peso has one of the longest histories of any currency in the Americas. The Spanish colonial peso de ocho (piece of eight) — minted in Mexico from the 16th century onward — was the world's first global currency, circulating from Asia to Europe and used as legal tender in the United States until 1857. After independence in 1821, Mexico retained the peso as its currency.

The 20th century brought repeated crises. Mexico devalued the peso dramatically in 1976, 1982, and again in 1994 — the so-called Tequila Crisis, triggered by a sudden devaluation that caused a currency collapse and required a $50 billion US-led bailout. In 1993, Mexico introduced the nuevo peso at 1,000 old pesos to one new peso, dropping three zeros to simplify exchange. Today's MXN has floated freely since 1995 and is fully convertible.

Economy & Trade

Mexico is the 15th-largest economy in the world and the second-largest in Latin America. Its economy is highly export-oriented — Mexico is consistently one of the top ten global exporters. Key exports include manufactured goods (automobiles, electronics, machinery), oil, silver, and agricultural products. Mexico is the world's largest producer of silver and a top-five producer of gold.

The peso's value is strongly linked to the US dollar through trade, investment flows, and remittances. USD/MXN is among the most actively traded emerging market currency pairs. Banxico, established as an independent central bank in 1994, operates an inflation-targeting framework and has built credibility through disciplined monetary policy — a factor that, along with high interest rates, attracts carry trade flows into the peso.

Key Facts

• The Spanish colonial peso de ocho minted in Mexico was the world's first truly global currency, circulating on every continent for over 300 years.
• Mexico is the world's largest producer of silver — a key export that has shaped the peso's identity since colonial times.
• The 1994 Tequila Crisis caused the peso to lose about half its value in weeks and triggered a broader contagion across emerging markets.
• Remittances from Mexicans abroad — over $60 billion per year — surpass oil revenues as Mexico's top source of foreign income.
• USD/MXN is one of the most liquid EM currency pairs, with tight bid-ask spreads and deep market depth even during volatile sessions.
• The MXN is sometimes called a proxy for broader Latin American risk sentiment: when global investors shy away from EM risk, the peso often leads the selloff.
