Value of $100 in 1915, adjusted to 1938

What happened to prices between 1915 and 1938

Between 1915 and 1938, the Consumer Price Index went from 10.1 to 14.1. Cumulatively, prices increased 39.6%, which works out to an average of 1.46% per year. Put differently, a dollar in 1915 bought what $0.72 buys in 1938.

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: 1938

Consumer prices fell 2.1% in 1938, reversing most of 1937’s gain and interrupting four straight years of recovery from the Depression’s trough. The National Bureau of Economic Research dates the bottom of the downturn, which had begun that May, to June 1938, a sharp 13-month contraction that briefly pushed unemployment back up near 19%. Even in a year the economy was shrinking again, Congress passed one of the New Deal’s most lasting reforms. The Fair Labor Standards Act, signed June 25 and effective that October, established the first federal minimum wage, 25 cents an hour, capped the standard workweek at 44 hours with time-and-a-half overtime beyond it, and restricted the employment of children in most industries. The wage floor and hours limits applied only to workers engaged in interstate commerce at first, but they set a precedent that would expand in the decades that followed. Consumer prices stood 42.4% above their 1913 level and 17.5% below their 1929 peak, evidence of how far the recovery still had to go even eight years after the Depression began. First-class postage held at 3 cents.
