What happened to prices between 1946 and 2021

Between 1946 and 2021, the Consumer Price Index went from 19.5 to 270.97. Cumulatively, prices increased 1289.6%, which works out to an average of 3.57% per year. Put differently, a dollar in 1946 bought what $0.07 buys in 2021.

Consumer prices rose 8.3% in 1946, up sharply from 1945’s 2.3% and the sharpest increase since 1942, as wartime price controls finally came apart. Congress let the Office of Price Administration’s authority lapse at the end of June, reinstated a weaker version soon after, then wound the whole system down through the rest of the year, releasing years of pent-up demand into the price level almost at once. Meat was the clearest casualty of the fight over decontrol: farmers withheld livestock rather than sell at capped prices, producing severe shortages that spring and summer until ceilings on meat were lifted that October, after which supplies reappeared almost overnight. Labor cashed in its own wartime restraint the same year. An estimated 4.6 million workers walked out at some point in 1946, hitting steel, coal, automakers, and the railroads in the largest strike wave in U.S. history, as unions pushed for wage gains to offset cost-of-living increases controls could no longer contain. Amid the turmoil, Congress made a less visible but lasting change to economic policy: the Employment Act of 1946, signed that February, committed the federal government to promoting maximum employment and created the Council of Economic Advisers. Consumer prices stood 97.0% above their 1913 level, nearly double where the index had started 33 years earlier. First-class postage held at 3 cents, and the minimum wage stayed at 40 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.
