Costa Rican colón
Since October 17, 2006 the colón is no longer bound to controlled devaluations (known in Costa Rica as minidevaluaciones) by the Central Bank of Costa Rica. With the new system, sistema cambiario de bandas, the exchange rates posted by the Central Bank are a "reference" and each authorized financial institution can determine their value independently in hopes that the free market will provide a mechanism to keep them reasonable.
