What happened to prices between 1921 and 1945

Between 1921 and 1945, the Consumer Price Index went from 17.9 to 18. Cumulatively, prices increased 0.6%, which works out to an average of 0.02% per year. Put differently, a dollar in 1921 bought what $0.99 buys in 1945.

Consumer prices fell 10.5% in 1921, the mirror image of the wartime inflation that had more than doubled the cost of living between 1913 and 1920. The Depression of 1920-21, one of the sharpest contractions in U.S. history, bottomed out that July according to the National Bureau of Economic Research, even though it had lasted barely eighteen months. Unemployment climbed toward one worker in ten as businesses cut production and prices to work through wartime inventories, but the same collapse in prices also meant the recovery, once it started, had room to run without reigniting inflation. Warren Harding took office March 4, promising a return to “normalcy” after a decade of war, pandemic, labor unrest, and rapid price swings; his administration moved quickly to cut top income tax rates and federal spending. Congress also acted on immigration that year: the Emergency Quota Act, signed May 19, capped annual arrivals from each country at 3% of that nationality’s population in the 1910 census, the first time the United States had set a numerical ceiling on immigration. The law favored northern and western Europe and cut total immigration by more than half compared with prewar levels; Congress tightened the formula again in 1924. First-class postage held at 2 cents, unchanged since mid-1919.

The destination year: 1945

Consumer prices rose 2.3% in 1945, up from 1944’s 1.7% but still modest, a rate that understated how much pressure had built up behind wartime price and wage controls, which stayed largely in place even as the conflict that justified them came to a close. The year opened with a shock at home: Franklin Roosevelt died of a cerebral hemorrhage on April 12, less than three months into an unprecedented fourth term, and Vice President Harry Truman was sworn in that same afternoon. The war Roosevelt had led for nearly four years ended without him. Germany surrendered on May 8, and Japan surrendered on August 15, after atomic bombs fell on Hiroshima and Nagasaki that month, with the formal signing aboard the USS Missouri on September 2. Domestic policy kept moving even as the guns fell silent: the federal minimum wage rose to 40 cents an hour that October 24, the final step of the schedule Congress had built into the 1938 Fair Labor Standards Act, up from 30 cents in 1939 and 25 cents at the law’s start. Consumer prices stood 81.8% above their 1913 level, a gain that would look modest next to what followed once wartime controls actually came off. First-class postage held at 3 cents.
