Between 1980 and 2021, the Consumer Price Index went from 82.4 to 270.97.
Cumulatively, prices increased 228.8%, which works out to an average of
2.95% per year. Put differently, a dollar in 1980 bought what
$0.30 buys in 2021.
1980 sat at the very peak of the Great Inflation. Prices rose 13.5% in that
single year, mortgage rates were climbing toward 16%, and the Federal Reserve
under Paul Volcker was administering the painful interest-rate medicine that
would finally break the inflationary spiral, at the cost of the deep 1981–82
recession. No single year looms larger in how Americans think about inflation.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1980 spending costs in 2021, by category:

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.
