What happened to prices between 1917 and 1924

Between 1917 and 1924, the Consumer Price Index went from 12.8 to 17.1. Cumulatively, prices increased 33.6%, which works out to an average of 4.22% per year. Put differently, a dollar in 1917 bought what $0.75 buys in 1924: the 1917 dollar lost 25.1% of its purchasing power over these 7 years.

1917 is when World War I inflation stopped being a background trend and became the dominant fact of American economic life. Consumer prices rose 17.4% for the year, more than double the previous year’s already sharp increase, as the country’s April 6 entry into the war layered federal war spending on top of an economy already strained by military demand and worker shortages. Congress paid for the war with the War Revenue Act that October, which sharply raised income taxes, created a new tax on wartime business profits, and, in a small but very visible change for ordinary households, raised the cost of a first-class stamp from 2 cents to 3 cents that November, the rate’s first move since 1885. Herbert Hoover took over the new Food Administration in August and asked Americans to conserve food voluntarily rather than face formal rationing, a campaign that became famous enough that “Hooverize” entered the language as a verb for cutting back. None of it slowed prices much: the 17.4% increase would be topped again the very next year, in 1918.

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.
