Value of $100 in 1931, adjusted to 1945

What happened to prices between 1931 and 1945

Between 1931 and 1945, the Consumer Price Index went from 15.2 to 18. Cumulatively, prices increased 18.4%, which works out to an average of 1.22% per year. Put differently, a dollar in 1931 bought what $0.84 buys in 1945.

Consumer prices fell 9.0% in 1931, a sharp acceleration from the 2.3% decline in 1930, as falling wages, collapsing farm prices, and a fresh wave of bank failures fed a downward spiral that the still-contracting economy could not shake. More than 2,000 banks failed during the year, far more than in 1930, as depositors who had watched earlier banks go under pulled their cash out of ones they feared were next. The crisis went international that September, when Britain suspended the gold standard amid a run on sterling. The Federal Reserve’s response made the domestic downturn worse before it made anything better: to defend the dollar’s own gold backing, the Fed raised its discount rate sharply that October, in two steps from 1.5% to 3.5%, tightening credit at the exact moment the economy needed the opposite. Not every headline that year was grim. The Empire State Building opened its doors on May 1, briefly the tallest building in the world, though so much of Manhattan’s office space sat vacant amid the Depression that tenants stayed scarce and New Yorkers took to calling it the “Empty State Building.” Consumer prices had now fallen for two straight years and stood 53.5% above their 1913 level, down from the 68.7% margin of just twelve months before. First-class postage remained at 2 cents.

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.
