Code of Federal Regulations Title 31. Money and Finance–Treasury § 31.281.6 Withdrawals from Treasury accounts

(a) Sales. With respect to the sale of foreign exchange held in accounts of the Secretary, the payment in dollars shall be calculated at the rate of exchange that would otherwise be available to the United States for the acquisition of the foreign exchange for its official disbursements unless otherwise determined by the Treasury Department in consultation with the agencies concerned. When the rate that would otherwise be available to the United States is not readily ascertainable, the Treasury Department shall be consulted. The dollar proceeds realized from the sale of exchange shall be credited to the appropriate receipt, appropriation or refund account on the books of the Treasury. The dollar payment for foreign exchange purchased shall not be charged as an appropriation expenditure until the foreign exchange is disbursed.

(b) Transfers without reimbursement. When foreign exchange is to be obtained from the Treasury Department without payment of dollars, the agency concerned shall furnish written certification that the exchange may be used without reimbursement to the Treasury, citing the relevant legal authority. In cases where international agreements or Bureau of the Budget allocations specify the programs for which foreign exchange may be used, the Secretary may transfer exchange to agencies without requiring a certification.
