The war had equally profound effects on patterns of international trade and finance. The united states supplied vast quantities of Allied war material and financed this through Lend Lease. In spite of this largess, Britain liquidated its foreign reserves and large portions of its overseas investments to pay for imports from the United States. By the war's end, the pattern of British trade deficits financed by U.S. capital was firmly established. In addition, the rupture created by military operations made reestablishing prewar trade practices difficult.
