What happened to prices between 1917 and 1946

Between 1917 and 1946, the Consumer Price Index went from 12.8 to 19.5. Cumulatively, prices increased 52.3%, which works out to an average of 1.46% per year. Put differently, a dollar in 1917 bought what $0.66 buys in 1946.

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: 1946

Consumer prices rose 8.3% in 1946, up sharply from 1945’s 2.3% and the sharpest increase since 1942, as wartime price controls finally came apart. Congress let the Office of Price Administration’s authority lapse at the end of June, reinstated a weaker version soon after, then wound the whole system down through the rest of the year, releasing years of pent-up demand into the price level almost at once. Meat was the clearest casualty of the fight over decontrol: farmers withheld livestock rather than sell at capped prices, producing severe shortages that spring and summer until ceilings on meat were lifted that October, after which supplies reappeared almost overnight. Labor cashed in its own wartime restraint the same year. An estimated 4.6 million workers walked out at some point in 1946, hitting steel, coal, automakers, and the railroads in the largest strike wave in U.S. history, as unions pushed for wage gains to offset cost-of-living increases controls could no longer contain. Amid the turmoil, Congress made a less visible but lasting change to economic policy: the Employment Act of 1946, signed that February, committed the federal government to promoting maximum employment and created the Council of Economic Advisers. Consumer prices stood 97.0% above their 1913 level, nearly double where the index had started 33 years earlier. First-class postage held at 3 cents, and the minimum wage stayed at 40 cents an hour.
