Value of $100 in 1915, adjusted to 1924

What happened to prices between 1915 and 1924

Between 1915 and 1924, the Consumer Price Index went from 10.1 to 17.1. Cumulatively, prices increased 69.3%, which works out to an average of 6.03% per year. Put differently, a dollar in 1915 bought what $0.59 buys in 1924.

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: 1924

Consumer prices held flat in 1924, the CPI’s annual average unchanged from 1923 after swinging from a sharp postwar drop to a modest rise the year before. That stability, extending the calm that had settled in after the deflation of 1921 and 1922, became a defining feature of the rest of the decade. Congress tightened immigration policy further with the Immigration Act of 1924, signed May 26, which cut the national-origins quota from 3% of each nationality’s 1910 census population to 2% of its 1890 population, shifting admissions further toward northern and western Europe and effectively excluding most immigration from Asia. Abroad, the U.S.-backed Dawes Plan, adopted that August, reorganized Germany’s war reparations payments and opened the way for American loans into the German economy, helping stabilize European currencies after the hyperinflation that had peaked in 1923. At home, Calvin Coolidge, who had served out the remainder of Warren Harding’s term after his death the previous year, won a full term of his own that November, campaigning on continued prosperity and limited government. First-class postage remained at 2 cents, a price unchanged since mid-1919.
