Nicaraguan Córdoba (NIO)

Established in 1960 during a period of economic modernization, the Banco Central de Nicaragua assumed control from commercial banks that had previously managed the country's monetary operations. The bank operates a distinctive crawling peg system — the córdoba depreciates against the U.S. dollar at a pre-announced annual rate, gradually adjusted downward from the original 12% pace set in 1991. This mechanism gives businesses exchange rate predictability while allowing gradual adjustments for inflation differentials between Nicaragua and its main trading partners.

The currency bears the name of Francisco Hernández de Córdoba, the Spanish conquistador who founded León and Granada — Nicaragua's earliest colonial cities — in 1524. When the córdoba debuted in 1912, it replaced a chaotic mix of currencies that had circulated since independence. The government pegged it at par with the U.S. dollar, a rate that held for decades of relative calm.
