(13)A contract for the exchange of one currency against another currency should be understood as relating to a direct and unconditional exchange of those currencies. In the case of a contract with multiple exchanges, each exchange should be considered separately. However an option or a swap on a currency should not be considered a contract for the sale or exchange of a currency and therefore could not constitute either a spot contract or means of payment regardless of the duration of the swap or option and regardless of whether it is traded on a trading venue or not.
