The Mexican Peso Crisis

The Mexican peso crisis of 1994–1995 introduced global investors to the concept of emerging market currency risk at scale. Mexico in early 1994 appeared to be a success story: NAFTA had just entered into force, foreign investment was flooding in, and the Salinas government had successfully stabilized the economy after the turbulent 1980s. By December, the peso had collapsed, Mexico was days from default, and the contagion—dubbed the Tequila Effect—was destabilizing currencies and stock markets from Argentina to the Philippines.

The structural vulnerabilities

Three weaknesses made Mexico vulnerable to the crisis that followed. First, the peso was overvalued. The government had used a crawling peg against the dollar as an anti-inflation anchor, but with Mexican inflation consistently above U.S. inflation, the real exchange rate appreciated steadily, eroding export competitiveness and widening the current account deficit to approximately 8 percent of GDP.

Second, the government had been financing much of its deficit through tesobonos—short-term dollar-denominated bonds that carried no currency risk for foreign investors but concentrated that risk entirely on Mexico. When confidence wavered, tesobono holders would demand repayment in dollars, requiring Mexico to have large foreign exchange reserves.

Third, the political environment was uniquely destabilizing in 1994. The Zapatista uprising in Chiapas on January 1—the day NAFTA took effect—was followed by the assassination of presidential candidate Luis Donaldo Colosio in March and the murder of the ruling party's secretary-general in September. Each event accelerated capital outflows.

The devaluation and its aftermath

After exhausting its foreign reserves in a futile defense of the peso, the government announced a devaluation on December 20, 1994. The initial 15 percent devaluation immediately proved insufficient, and within two days the peso was in free float. It ultimately fell roughly 50 percent against the dollar. The economic consequences were severe: inflation spiked, real wages collapsed, unemployment rose sharply, and the banking system—loaded with dollar-denominated liabilities—faced a severe solvency crisis.

The U.S. Treasury, concerned about contagion to other emerging markets and the implications for NAFTA, assembled a $50 billion rescue package with IMF support—including $20 billion drawn from the Exchange Stabilization Fund, which required no Congressional approval. Mexico repaid the loans ahead of schedule, but the political and social costs of the crisis were substantial.
