What happened to prices between 1986 and 2021
Between 1986 and 2021, the Consumer Price Index went from 109.6 to 270.97.
Cumulatively, prices increased 147.2%, which works out to an average of
2.62% per year. Put differently, a dollar in 1986 bought what
$0.40 buys in 2021: the 1986 dollar
lost 59.6% of its purchasing power over
these 35 years.
1986 delivered the decade’s biggest one-year drop in inflation, and it came
almost entirely from a single source: oil. Saudi Arabia abandoned its policy
of restraining output to prop up prices, and world crude collapsed from
about $27 a barrel to under $10 by midyear. Gasoline, which had averaged
$1.12 a gallon in 1985, fell to 86 cents. With energy costs plunging,
headline CPI inflation for the year came in at just 1.9%, the lowest annual
rate since 1965 and a striking bookend to 1980’s 13.5% peak. The relief was
uneven: prices for most goods and services outside energy kept rising at a
moderate pace, so households that didn’t drive much or heat with oil felt
less of the difference. In October, Congress passed the Tax Reform Act of
1986, a bipartisan overhaul that cut the top individual income tax rate from
50% to 28% while closing many deductions and shelters, the broadest rewrite
of the federal tax code since World War II. Between cheap gas and falling
interest rates, 1986 read like proof that the inflationary 1970s were a
closed chapter, six years after the U.S. economy had felt anything but
calm.
Every 1986 amount converts to 2021 at the same ratio, 2.47: $1,000 becomes
$2,472, and $10,000 becomes $24,724.

Year by year: CPI and the value of $100 from 1986
$100 from 1986 had already become $172 by
2004, on its way to $247 in 2021; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 5.4% in 1990, and prices fell 0.4% in 2009, the deepest deflation of the period.
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 2021
In 2021, prices rose 4.7% and $100 from 1986 had the buying
power of $247; the year's average CPI of 270.97 is the level
behind every 2021 figure on this page.
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.
