What happened to prices between 1921 and 1955

Between 1921 and 1955, the Consumer Price Index went from 17.9 to 26.8. Cumulatively, prices increased 49.7%, which works out to an average of 1.19% per year. Put differently, a dollar in 1921 bought what $0.67 buys in 1955.

Consumer prices fell 10.5% in 1921, the mirror image of the wartime inflation that had more than doubled the cost of living between 1913 and 1920. The Depression of 1920-21, one of the sharpest contractions in U.S. history, bottomed out that July according to the National Bureau of Economic Research, even though it had lasted barely eighteen months. Unemployment climbed toward one worker in ten as businesses cut production and prices to work through wartime inventories, but the same collapse in prices also meant the recovery, once it started, had room to run without reigniting inflation. Warren Harding took office March 4, promising a return to “normalcy” after a decade of war, pandemic, labor unrest, and rapid price swings; his administration moved quickly to cut top income tax rates and federal spending. Congress also acted on immigration that year: the Emergency Quota Act, signed May 19, capped annual arrivals from each country at 3% of that nationality’s population in the 1910 census, the first time the United States had set a numerical ceiling on immigration. The law favored northern and western Europe and cut total immigration by more than half compared with prewar levels; Congress tightened the formula again in 1924. First-class postage held at 2 cents, unchanged since mid-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.
