Concept
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. In response, the Mexican central bank intervened in the foreign exchange markets to maintain the Mexican peso's peg to the U.S. dollar by issuing dollar-denominated public debt to buy pesos. The peso's strength caused demand for imports to increase in Mexico, resulting in a trade deficit. Speculators recognized an overvalued peso and capital began flowing out of Mexico to the United States, increasing downward market pressure on the peso. Under election pressures, Mexico purchased its own treasury securities to maintain its money supply and avert rising interest rates, drawing down the bank's dollar reserves. Supporting the money supply by buying more dollar-denominated debt while simultaneously honoring such debt depleted the bank's reserves by the end of 1994. The central bank devalued the peso on December 20, 1994, and foreign investors' fear led to an even higher risk premium. To discourage the resulting capital flight, the bank raised interest rates, but higher costs of borrowing merely hurt economic growth. Unable to sell new issues of public debt or efficiently purchase dollars with devalued pesos, Mexico faced a default.
