The Central Bank of Nicaragua has published a Standard for the Exchange of Banknotes and Coins, setting out the criteria and obligations for the central bank and banks supervised by the Superintendency of Banks and Other Financial Institutions to provide exchange services for legal tender córdobas through their branch networks. The standard covers exchanging notes and coins in current circulation for other denominations, replacing deteriorated or mutilated notes and coins with currency fit for circulation, and exchanging notes and coins that are in the process of being withdrawn. Exchanges of damaged or mutilated currency and exchanges linked to withdrawal processes must be provided free of charge and without amount limits for all requesters. For simple change, the Central Bank of Nicaragua must provide the service free of charge and without limits, and banks must do the same for their customers, while being allowed to charge fees to non-customers. All exchanges must be settled with notes and coins suitable for circulation.
