What happened to prices between 1918 and 1955

Between 1918 and 1955, the Consumer Price Index went from 15.1 to 26.8. Cumulatively, prices increased 77.5%, which works out to an average of 1.56% per year. Put differently, a dollar in 1918 bought what $0.56 buys in 1955.

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: 1955

Consumer prices fell 0.4% in 1955, the first annual decline since 1949, as a strong rebound from the 1953-54 recession delivered growth without much price pressure; automakers and appliance makers competed hard on price for a booming consumer market. Organized labor consolidated that December, when the American Federation of Labor and the Congress of Industrial Organizations merged on the 5th under President George Meany, uniting roughly 15 million workers in the AFL-CIO after two decades as rival federations. That same day, a different kind of organizing began in Montgomery, Alabama: four days after Rosa Parks was arrested for refusing to give up her bus seat to a white passenger, the city’s Black community began a boycott of its buses that would last more than a year and help launch the civil rights movement’s mass phase. Markets got a scare that September: news of Eisenhower’s heart attack on the 24th sent the Dow Jones Industrial Average to its steepest one-day drop since the 1929 crash when trading resumed that Monday, before stocks recovered as the president’s health improved. Consumer prices finished 1955 170.7% above their 1913 level, essentially unchanged from where they stood a year earlier. First-class postage held at 3 cents, and the minimum wage stayed at 75 cents an hour.
