Value of $100 in 1915, adjusted to 1927

What happened to prices between 1915 and 1927

Between 1915 and 1927, the Consumer Price Index went from 10.1 to 17.4. Cumulatively, prices increased 72.3%, which works out to an average of 4.64% per year. Put differently, a dollar in 1915 bought what $0.58 buys in 1927.

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: 1927

Consumer prices fell 1.7% in 1927, a mild retreat after three years of gradual increases and part of a shallow up-and-down pattern that ran through the second half of the decade. Aviation delivered the year’s signature moment: Charles Lindbergh departed Roosevelt Field, New York, on May 20 and landed at Le Bourget Field outside Paris roughly 33.5 hours later, the first person to fly the Atlantic solo and nonstop. Detroit closed a chapter of its own that May, when Ford halted the Model T’s production line after nearly 19 years and more than 15 million cars sold, idling tens of thousands of workers while its factories retooled for the Model A. The Federal Reserve, meeting with European central bankers that summer, cut its discount rate to ease pressure on currencies still recovering from the war, a move later cited by economists including Milton Friedman and Anna Schwartz as fuel for the stock market speculation that built through the following two years. First-class postage held at 2 cents.
