The peso has a long history, dating back to the Spanish colonial period, and has undergone various changes in value and design over the years. As a major currency in Latin America, the peso is widely used in trade and tourism. Its value can fluctuate based on economic conditions, inflation, and political stability in Mexico. The Bank of Mexico is responsible for issuing and regulating the currency to maintain its stability.
