Value of $100 in 1915, adjusted to 1974

What happened to prices between 1915 and 1974

Between 1915 and 1974, the Consumer Price Index went from 10.1 to 49.3. Cumulatively, prices increased 388.1%, which works out to an average of 2.72% per year. Put differently, a dollar in 1915 bought what $0.20 buys in 1974.

Consumer prices rose 1.0% in 1915, the second straight year of near-flat inflation before the wartime price surges of 1916 through 1918. The year’s defining event had nothing to do with prices directly: a German submarine sank the British liner Lusitania off the Irish coast on May 7, killing 128 Americans and hardening U.S. opinion against Germany two years before the country entered the war. Economically, 1915 was a turning point of a different kind. A recession that had dragged on since 1913 began lifting as Britain and France placed growing orders for steel, munitions, and other war materiel with American manufacturers, and U.S. exports to the Allied powers climbed sharply through the year. That demand would keep building through 1916, eventually pulling prices up with it. On the regulatory side, the Federal Trade Commission opened for business in March, taking on enforcement of the Clayton Antitrust Act that Congress had passed the previous fall. A first-class stamp still cost 2 cents, unchanged since 1885 and still two years from its first wartime increase.

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.
