What happened to prices between 1966 and 2020

Between 1966 and 2020, the Consumer Price Index went from 32.4 to 258.811. Cumulatively, prices increased 698.8%, which works out to an average of 3.92% per year. Put differently, a dollar in 1966 bought what $0.13 buys in 2020.

Consumer prices rose 2.9% in 1966, nearly double 1965’s 1.6% as Vietnam War spending kept climbing without an offsetting tax increase, pushing the economy closer to capacity and prices higher along with it. Medicare coverage took effect that July 1, extending federal health insurance to roughly 19 million Americans age 65 and older under the program signed into law the year before. The Federal Reserve had already moved to cool the overheating economy, raising its discount rate the previous December over White House objections; the tightening carried into 1966 as the first postwar credit crunch, freezing parts of the housing and municipal bond markets even as inflation kept climbing. Congress widened the wage floor’s reach that September 23, when the Fair Labor Standards Amendments of 1966 set a $1.40 minimum wage effective the following February and extended coverage to roughly 9 million more workers in retail, hospitals, schools, and other services not previously covered. Consumer prices finished 1966 227.3% above their 1913 level. First-class postage held at 5 cents, and the minimum wage stayed at $1.25 an hour for the rest of the year.

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.
