What happened to prices between 1940 and 1951

Between 1940 and 1951, the Consumer Price Index went from 14 to 26. Cumulatively, prices increased 85.7%, which works out to an average of 5.79% per year. Put differently, a dollar in 1940 bought what $0.54 buys in 1951.

Consumer prices rose 0.7% in 1940, snapping 1939’s decline and marking the first increase since 1937. The gain was modest, and the CPI still stood 18.1% below its 1929 peak, a reminder of how far the recovery from the Depression’s trough had left to go even as defense orders from Britain and France began reaching American factories. War was already reshaping domestic policy well before it touched American soil. Congress passed the Selective Training and Service Act that September, the country’s first peacetime draft, requiring men aged 21 to 35 to register and authorizing the induction of up to 900,000 men a year, more than a year before Pearl Harbor. That November, Franklin Roosevelt won an unprecedented third term, defeating Republican Wendell Willkie after campaigning on keeping the United States out of the war then consuming Europe and Asia. The promise would not hold much longer: within two years, wartime demand would push consumer prices up faster than at any point since the aftermath of World War I. First-class postage held at 3 cents, and the federal minimum wage stayed at 30 cents an hour, the level set the previous October under the Fair Labor Standards Act.

The destination year: 1951

Consumer prices rose 7.9% in 1951, up sharply from 1950’s 1.3% and the fastest increase since 1947, as Korean War buying and a defense spending surge hit an economy still adjusting to peacetime. Much of the jump came early in the year, before the government stepped in: the Office of Price Stabilization imposed a general ceiling on prices January 26, and the Wage Stabilization Board froze wages soon after, the broadest peacetime controls since the war began that June. The year’s more lasting change came in monetary policy. On March 4, the Treasury and the Federal Reserve signed the Accord, ending the Fed’s wartime obligation to hold down interest rates on government bonds and freeing the central bank to fight inflation on its own terms for the first time since 1942, a shift that would shape Fed independence for decades. Congress raised taxes that October to help pay for the war: the Revenue Act of 1951, signed October 20, lifted individual and corporate income taxes along with a range of excise taxes, the third increase in taxes since fighting began in Korea. Consumer prices finished 1951 162.6% above their 1913 level. First-class postage held at 3 cents, and the minimum wage stayed at 75 cents an hour.
