All payments at facilities operating in foreign currencies in Cuba must be made with convertible pesos. Convertible pesos will remain at par with the US dollar at an exchange rate of one for one. You may exchange US dollars, Euros, Canadian dollars, Pounds Sterling or Swiss francs for convertible pesos (CUC). The exchange rates for those currencies are set in accord with the exchange rates on the international market plus 8 percent as a result of the reevaluation of convertible peso (CUC) since April 9th, 2005. Furthermore, when exchanging US dollars for convertible pesos a service charge of 10 percent will be levied, to protect Cuba's economic interests. You may exchange convertible pesos (CUC) for US dollars or for other convertible currencies in any of the money-exchange offices in Cuba (at the current international exchange rate).
Credit cards are accepted only when issued by non-US banks. Visa and American Express Traveler's checks are exchangeable at most Cuban banks.
