Value of $100 in 1915, adjusted to 1936

What happened to prices between 1915 and 1936

Between 1915 and 1936, the Consumer Price Index went from 10.1 to 13.9. Cumulatively, prices increased 37.6%, which works out to an average of 1.53% per year. Put differently, a dollar in 1915 bought what $0.73 buys in 1936.

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: 1936

Consumer prices rose 1.5% in 1936, a third straight annual increase and part of a slow, steady climb back from the 1933 trough, though prices and the broader economy still had not fully recovered to their pre-Depression levels. Voters delivered their verdict on that recovery in November, reelecting Franklin D. Roosevelt over Republican Alf Landon in one of the most lopsided elections in U.S. history: Roosevelt carried 46 of 48 states and won the Electoral College 523 to 8, a broad public endorsement of the New Deal. Public works kept advancing that year, too. Hoover Dam, one of the era’s signature projects, had been dedicated in September 1935, but its first generators did not begin sending electricity over transmission lines to Los Angeles until October 1936, a milestone that showed how long even a celebrated project took to reach full operation. Consumer prices ended the year 40.4% above their 1913 level, still 18.7% below the 1929 peak, a gap that would keep narrowing until a sharp new recession interrupted the recovery the following year. First-class postage held at 3 cents.
