Value of $100 in 1931, adjusted to 1974

What happened to prices between 1931 and 1974

Between 1931 and 1974, the Consumer Price Index went from 15.2 to 49.3. Cumulatively, prices increased 224.3%, which works out to an average of 2.77% per year. Put differently, a dollar in 1931 bought what $0.31 buys in 1974.

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: 1974

1974 was the year the postwar economy broke its old rules. Consumer prices rose 11.0%, the fastest annual increase since 1947, as the Arab oil embargo that ran from October 1973 to March 1974 roughly quadrupled the price of crude oil worldwide. Gasoline, which had averaged 38.5 cents a gallon in 1973, jumped to 53.2 cents, and shortages forced many states into odd-even rationing at the pump. Nixon’s wage and price controls, in place in some form since 1971, expired at the end of April, removing the last brake on prices just as the oil shock hit. Nixon himself resigned in August over Watergate, and Gerald Ford’s response to inflation, a voluntary “Whip Inflation Now” campaign built around lapel buttons, became a symbol of how little conventional politics could do against the problem. Prices kept climbing even as the economy weakened: a recession that started in November 1973 dragged on, the Dow fell to a bear-market bottom of 577.60 in December, and unemployment was already rising toward the 9% it would reach in 1975. The combination of rising prices and a shrinking economy gave the decade its name: stagflation.
