Value of $100 in 1917, adjusted to 1922

What happened to prices between 1917 and 1922

Between 1917 and 1922, the Consumer Price Index went from 12.8 to 16.8. Cumulatively, prices increased 31.3%, which works out to an average of 5.59% per year. Put differently, a dollar in 1917 bought what $0.76 buys in 1922.

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.

The destination year: 1922

Consumer prices fell another 6.1% in 1922, the second straight year of decline, even as the broader economy climbed out of the Depression of 1920-21 and industrial production rebounded. The CPI had now given back roughly a third of its wartime runup, though it stayed well above the 1913 baseline. Congress moved to shield that recovery from foreign competition: the Fordney-McCumber Tariff Act, signed September 21, raised duties on hundreds of imported goods to some of the highest levels in U.S. history, a policy meant to protect farmers and manufacturers still adjusting to postwar prices. Labor tension flared even as prices fell. Roughly half a million bituminous coal miners struck that April over wage cuts employers had imposed as prices dropped, and hundreds of thousands of railroad shop workers walked out in July in a separate dispute over pay and work rules, together the largest strike wave since 1919. Both disputes dragged on for months and drew federal mediation before ending without full concessions for the workers. First-class postage remained at 2 cents.
