What happened to prices between 1918 and 1943

Between 1918 and 1943, the Consumer Price Index went from 15.1 to 17.3. Cumulatively, prices increased 14.6%, which works out to an average of 0.55% per year. Put differently, a dollar in 1918 bought what $0.87 buys in 1943.

1918 brought the steepest annual price increase the CPI had recorded: consumer prices rose 18.0% for the year, edging out 1917’s already sharp 17.4% as the economy stayed at full wartime mobilization for most of the year. A first-class stamp cost 3 cents, up from 2 cents the previous November under the War Revenue Act’s wartime tax increases. The war itself ended on November 11, when Germany signed an armistice with the Allied powers after more than four years of fighting in Europe, but the inflation built up over a year and a half of mobilization did not disappear along with the fighting. The bigger public health story that year was the influenza pandemic that reached the U.S. in a mild spring wave and then returned that fall in a far deadlier form, eventually killing roughly 675,000 Americans, more than the country’s combat losses in the war. It hit factories, docks, and shops alongside households, adding disruption to an economy already strained by wartime demand. Prices would keep climbing even after the armistice, into the postwar surge of 1919.

The destination year: 1943

Consumer prices rose 6.1% in 1943, a slower pace than 1942’s surge but still well above anything the country had seen before the war. The slowdown owed largely to the “Hold the Line” order, issued that April, which froze most wages, prices, and rents at their current levels after the previous year’s jump showed how far demand had outrun the existing controls. Rationing grew more sophisticated alongside the freeze: starting in February, a points system split scarce goods into red points for meat, butter, and other fats and blue points for canned and processed foods, letting households budget across categories instead of simply going without once a flat quota ran dry. The government also changed how it collected the taxes paying for all of it. The Current Tax Payment Act, signed June 9, required employers to withhold federal income tax directly from paychecks for the first time, smoothing the flow of wartime revenue and creating the pay-as-you-go system still used today. Consumer prices stood 74.7% above their 1913 level and 33.1% above 1933’s Depression-era low. First-class postage held at 3 cents, and the minimum wage stayed at 30 cents an hour.
