The peso (sign: $; code: MXN) is the currency of Mexico. The peso was the first currency in the world to use the "$" sign, which the United States dollar later adopted for its own use. The peso is the 12th most traded currency in the world and by far the most traded currency in Latin America and third most traded in all the Americas. The current ISO 4217 code for the peso is MXN; prior to the 1993 revaluation (see below), the code MXP was used. The peso is subdivided into 100 centavos, represented by "¢". The name was originally used in reference to pesos oro (gold weights) or pesos plata (silver weights). The translation of peso from Spanish to English is weight. As of September 28, 2009 its exchange rate was 13.5243 Mexican pesos against one U.S. dollar.

Economy of Mexico
The economy of Mexico is 11th to 13th largest in the world. Since the 1994 crisis, administrations have improved the country's macroeconomic fundamentals. Mexico was not significantly influenced by the recent 2002 South American crisis, and has maintained positive, although low, rates of growth after a brief period of stagnation in 2001.
Moody's (in March 2000) and Fitch IBCA (in January 2002) issued investment-grade ratings for Mexico's sovereign debt. In spite of its unprecedented macroeconomic stability, which has reduced inflation and interest rates to record lows and has increased per capita income, enormous gaps remain between the urban and the rural population, the northern and southern states, and the rich and the poor. Some of the government's challenges include the upgrade of infrastructure, the modernization of the tax system and labor laws, and the reduction of income inequality.
