What happened to prices between 1966 and 2021

Between 1966 and 2021, the Consumer Price Index went from 32.4 to 270.97. Cumulatively, prices increased 736.3%, which works out to an average of 3.94% per year. Put differently, a dollar in 1966 bought what $0.12 buys in 2021.

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: 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.
