Between 1947 and 2020, the Consumer Price Index went from 22.3 to 258.811.
Cumulatively, prices increased 1060.6%, which works out to an average of
3.42% per year. Put differently, a dollar in 1947 bought what
$0.09 buys in 2020.
Consumer prices rose 14.4% in 1947, up from 1946’s 8.3% and
the fastest annual increase since 1920, as the last of the wartime price
controls disappeared and a year of strikes, wage catch-up, and lingering
shortages hit consumers all at once. Congress answered the previous year’s
strike wave that June, overriding President Truman’s veto to pass the
Taft-Hartley Act, which banned secondary boycotts and the closed shop and
let states adopt “right-to-work” laws curbing union power. American
attention was also turning outward. In a June 5 speech at Harvard,
Secretary of State George Marshall outlined a U.S.-funded plan to rebuild
Western Europe’s economies, an effort that would become known as the
Marshall Plan once Congress funded it the following year. The government
reorganized itself for the confrontation with the Soviet Union that plan was
partly designed to prevent: the National Security Act, signed July 26,
created the Department of Defense, the Air Force as a separate service, the
Central Intelligence Agency, and the National Security Council. Consumer
prices stood 125.3% above their 1913 level and 30.4% above
1929’s pre-Depression peak, up from just 1.2% above it four
years earlier. First-class postage held at 3 cents, and the minimum wage
stayed at 40 cents an hour.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1947 spending costs in 2020, by category:

The destination year: 2020
2020 was the year the pandemic rewired the price data without triggering the
inflation spike that followed it. Consumer prices rose just 1.2% for the
year, the mildest pace since 2015, as COVID-19 lockdowns emptied roads,
closed airports, and crushed energy demand. Oil told the starkest story: on
April 20, U.S. crude futures fell to about negative $37 a barrel, the first
negative settlement in the market’s history, as storage capacity ran out and no one
wanted the physical barrels. Gasoline followed it down, falling to about
$1.80 a gallon nationally that month before recovering to average $2.17 for
the year. Grocery prices moved the other way: pantry stocking and
meatpacking-plant disruptions pushed food-at-home costs up faster than
usual, a rare case of food and energy pulling the index in opposite
directions. Washington answered with the $2.2 trillion CARES Act, signed
March 27, which sent $1,200 payments to most adults and added $600 a week
to unemployment benefits as states ordered widespread business closures.
The Federal Reserve cut its policy rate to near zero in two emergency moves
that same month and pledged to buy Treasury and mortgage bonds “in the
amounts needed” to keep credit markets working, an open-ended commitment
beyond even its 2008 response. None of it showed up in the CPI yet: the
stimulus, the supply shocks, and the reopening whiplash that followed would
build into the fastest inflation in four decades over the next two years.
