Truman let Lend-Lease expire in 1945

Did Truman's decision not to renew Lend-Lease alone cause Britain's postwar financial crisis?

No. Non-renewal ended wartime aid, and Attlee's government also chose a different balance between military commitments and domestic reform.

Truman's administration allowed Lend-Lease to expire after the war, ending direct financial and equipment aid. Britain's postwar position also reflected the priorities of the Labour government elected in 1945. Attlee accepted the need for social reform and put less weight on maintaining wartime-scale military commitments than Churchill. The correction separates the expiry of a wartime programme from the spending choices that followed.
