In Cuba, until 1 January 2021, there are two currencies, both called peso. One is the "Cuban peso" (in Spanish , ISO 4217 code: CUP) and the other is the Cuban convertible peso (ISO 4217 code: CUC, often called "dollar" in the spoken language). Both currencies are subdivided into 100 "centavos". The CUC was pegged to the US dollar at par, while the CUP is currently 25 CUP = 1 CUC = US$1, for cash exchanges. Both currencies are not traded internationally, and they cannot be bought in advance outside Cuba. Importation/exportation of CUCs is prohibited.
