What happened to prices between 1955 and 2021

Between 1955 and 2021, the Consumer Price Index went from 26.8 to 270.97. Cumulatively, prices increased 911.1%, which works out to an average of 3.57% per year. Put differently, a dollar in 1955 bought what $0.10 buys in 2021.

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.

The destination year: 2021

2021 was the year inflation stopped being background noise. Consumer prices rose 4.7% on average for the year, and the pace kept building as the months went on: by December, the 12-month rate had reached 7.0%, the highest since 1982. The proximate cause was a supply chain that could not keep up with a fast-reopening economy. A global semiconductor shortage choked new car production and pushed used vehicle prices up by more than a third, the single largest line item in the year’s inflation math. Lumber, appliances, and shipping capacity told versions of the same story: demand snapped back faster than factories, ports, and truckers could handle it. Washington added fuel in March with the $1.9 trillion American Rescue Plan, on top of the relief already in the pipeline since 2020. For most of the year, the Federal Reserve called the price surge “transitory,” a temporary reopening effect expected to fade on its own, and held its policy rate near zero. By November, with inflation still climbing, the Fed reversed course and began winding down its bond purchases, the first step toward the rate hikes that would follow in 2022. Gas averaged $3.01 a gallon for the year, up from about $2.17 in 2020, while the federal minimum wage held at $7.25, unchanged since 2009. In hindsight, 2021 reads as the hinge year: the point where “transitory” inflation became the multi-year fight the Fed spent the next two years trying to win.
