What happened to prices between 1955 and 2020

Between 1955 and 2020, the Consumer Price Index went from 26.8 to 258.811. Cumulatively, prices increased 865.7%, which works out to an average of 3.55% per year. Put differently, a dollar in 1955 bought what $0.10 buys in 2020.

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: 2020

2020 was the year the pandemic rewired the price data without triggering the inflation spike that followed it. Consumer prices rose just 1.2% for the year, the mildest pace since 2015, as COVID-19 lockdowns emptied roads, closed airports, and crushed energy demand. Oil told the starkest story: on April 20, U.S. crude futures fell to about negative $37 a barrel, the first negative settlement in the market’s history, as storage capacity ran out and no one wanted the physical barrels. Gasoline followed it down, falling to about $1.80 a gallon nationally that month before recovering to average $2.17 for the year. Grocery prices moved the other way: pantry stocking and meatpacking-plant disruptions pushed food-at-home costs up faster than usual, a rare case of food and energy pulling the index in opposite directions. Washington answered with the $2.2 trillion CARES Act, signed March 27, which sent $1,200 payments to most adults and added $600 a week to unemployment benefits as states ordered widespread business closures. The Federal Reserve cut its policy rate to near zero in two emergency moves that same month and pledged to buy Treasury and mortgage bonds “in the amounts needed” to keep credit markets working, an open-ended commitment beyond even its 2008 response. None of it showed up in the CPI yet: the stimulus, the supply shocks, and the reopening whiplash that followed would build into the fastest inflation in four decades over the next two years.
