What happened to prices between 1973 and 2021

Between 1973 and 2021, the Consumer Price Index went from 44.4 to 270.97. Cumulatively, prices increased 510.3%, which works out to an average of 3.84% per year. Put differently, a dollar in 1973 bought what $0.16 buys in 2021.

Consumer prices rose 6.2% in 1973, nearly double 1972’s 3.2%, as Nixon’s wage and price controls were phased out through the year and pressure the controls had been holding back broke loose. The bigger shock arrived that October, when Arab oil-producing states embargoed exports to the United States and other supporters of Israel in the Yom Kippur War. Crude oil, which had traded around $3 a barrel, approached $12 by early 1974, and gas lines became a fixture outside filling stations nationwide. Earlier in the year, the Paris Peace Accords, signed that January 27, ended direct American combat in Vietnam and set a 60-day deadline for withdrawing remaining U.S. troops, even as fighting between North and South Vietnam went on. Financial markets read the year correctly as a turning point: the Dow Jones Industrial Average peaked at 1,051.70 on January 11, a level it would not reach again until 1980, before the oil shock and rising interest rates dragged it into a two-year bear market. A median household earned $10,512 in 1973, a new home sold for a median $32,500, and gas averaged 38.5 cents a gallon, still under half of what the embargo’s effects would bring the following year. Consumer prices stood 348.5% above their 1913 level by year’s end, with the decade’s worst inflation still ahead.

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.
