Value of $100 in 1915, adjusted to 1968

What happened to prices between 1915 and 1968

Between 1915 and 1968, the Consumer Price Index went from 10.1 to 34.8. Cumulatively, prices increased 244.6%, which works out to an average of 2.36% per year. Put differently, a dollar in 1915 bought what $0.29 buys in 1968.

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: 1968

Consumer prices rose 4.2% in 1968, up sharply from 1967’s 3.1% and the fastest pace in 17 years, as Vietnam War spending and a tight labor market pushed inflation higher despite the Federal Reserve’s earlier tightening. The year was marked by political violence: Martin Luther King Jr. was assassinated on a motel balcony in Memphis on April 4, touching off rioting in more than 100 cities, and Robert F. Kennedy was shot in Los Angeles on June 5, moments after winning California’s Democratic presidential primary, and died the next day. Washington tried to answer the inflation problem directly that June 28, when Congress passed a 10% income tax surcharge, the Revenue and Expenditure Control Act, temporarily raising taxes and cutting spending to cool an economy overheated by war and Great Society outlays; prices kept accelerating anyway. The cost of living rose in smaller, more visible ways too: first-class postage climbed to 6 cents that January 7, and the minimum wage rose to $1.60 an hour that February 1, the final step of the increase Congress had set two years earlier. Consumer prices finished 1968 251.5% above their 1913 level.
