Between 1945 and 2020, the Consumer Price Index went from 18 to 258.811.
Cumulatively, prices increased 1337.8%, which works out to an average of
3.62% per year. Put differently, a dollar in 1945 bought what
$0.07 buys in 2020.
Consumer prices rose 2.3% in 1945, up from 1944’s 1.7% but
still modest, a rate that understated how much pressure had built up behind
wartime price and wage controls, which stayed largely in place even as the
conflict that justified them came to a close. The year opened with a shock
at home: Franklin Roosevelt died of a cerebral hemorrhage on April 12, less
than three months into an unprecedented fourth term, and Vice President
Harry Truman was sworn in that same afternoon. The war Roosevelt had led for
nearly four years ended without him. Germany surrendered on May 8, and
Japan surrendered on August 15, after atomic bombs fell on Hiroshima and
Nagasaki that month, with the formal signing aboard the USS Missouri on
September 2. Domestic policy kept moving even as the guns fell silent: the
federal minimum wage rose to 40 cents an hour that October 24, the final
step of the schedule Congress had built into the 1938 Fair Labor Standards
Act, up from 30 cents in 1939 and 25 cents at the law’s start. Consumer
prices stood 81.8% above their 1913 level, a gain that would
look modest next to what followed once wartime controls actually came off.
First-class postage held at 3 cents.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1945 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.
