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.
