What happened to prices between 1931 and 1949

Between 1931 and 1949, the Consumer Price Index went from 15.2 to 23.8. Cumulatively, prices increased 56.6%, which works out to an average of 2.52% per year. Put differently, a dollar in 1931 bought what $0.64 buys in 1949.

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: 1949

Consumer prices fell 1.2% in 1949, down from 1948’s 8.1% gain and the first annual decline since 1939, the first real break in a decade otherwise defined by wartime and postwar inflation. A mild recession drove the drop: the National Bureau of Economic Research dates a downturn from November 1948 to October 1949, as businesses worked off inventories built up during the postwar buying boom and price pressure finally eased. The Cold War hardened around the same time. On April 4, the United States, Canada, and ten Western European nations signed the North Atlantic Treaty, committing to treat an attack on one member as an attack on all and formalizing the Western alliance against Soviet expansion. That August 29, the Soviet Union tested its first atomic bomb, ending the American nuclear monopoly just four years after Hiroshima and Nagasaki and setting off an arms race that would run for decades. Congress closed out the decade’s wage policy that October, passing the Fair Labor Standards Amendments of 1949 to raise the federal minimum wage to 75 cents an hour effective the following January, nearly double the 40 cents that had held since 1945. The decade closed with consumer prices 140.4% above their 1913 level, up 70% since 1940 alone even after 1949’s decline. First-class postage held at 3 cents.
