The Mexican peso crisis was a currency crisis sparked by the Mexican government's sudden devaluation of the peso against the U.S. dollar in December 1994, which became one of the first international financial crises ignited by capital flight.
During the 1994 presidential election, the incumbent administration embarked on an expansionary fiscal and monetary policy. The Mexican treasury began issuing short-term debt instruments denominated in domestic currency with a guaranteed repayment in U.S. dollars, attracting foreign investors. Mexico enjoyed investor confidence and new access to international capital following its signing of the North American Free Trade Agreement (NAFTA). However, a violent uprising in the state of Chiapas, as well as the assassination of the presidential candidate Luis Donaldo Colosio, resulted in political instability, causing investors to place an increased risk premium on Mexican assets.
