Between 1920 and 1922, the Consumer Price Index went from 20 to 16.8.
Cumulatively, prices declined 16.0%, which works out to an average of
-8.35% per year. Put differently, a dollar in 1920 bought what
$1.19 buys in 1922.
1920 was the last year of the inflation that had built since the war began:
consumer prices rose 15.6% for the year, leaving the CPI more than double its
1913 starting level after seven straight years of increases.
The boom behind those increases turned to bust before the year was over. The
Federal Reserve, worried about speculation, pushed its discount rate to a
record 7% that spring, and wholesale prices, which had led the wartime
runup, began collapsing within months. The National Bureau of Economic
Research dates the resulting downturn from January 1920 to July 1921, one of
the shortest but steepest contractions in U.S. history, and consumer prices
followed into outright decline, falling 10.5% in 1921. Two constitutional
changes reshaped the country that year, too. The 18th Amendment’s ban on
alcohol took legal effect January 17, enforced under the Volstead Act
Congress had passed the previous October. Then, on August 18, Tennessee’s
ratification of the 19th Amendment secured women’s right to vote nationwide,
and women cast ballots in a presidential election for the first time that
November, when Warren Harding won on a promise to return the country to
“normalcy” after a decade of war, pandemic, and rising prices. First-class
postage held at 2 cents, unchanged since mid-1919.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1920 spending costs in 1922, by category:
Category
Avg. yearly inflation
$100 in 1920 →
All items (CPI-U)
-8.35%
$84.00
Food
-15.77%
$70.95
Apparel
-20.85%
$62.65
Not shown because the BLS began these indexes after 1920: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices fell another 6.1% in 1922, the second straight year of
decline, even as the broader economy climbed out of the Depression of
1920-21 and industrial production rebounded. The CPI had now given back
roughly a third of its wartime runup, though it stayed well above the
1913 baseline. Congress moved to shield that recovery from
foreign competition: the Fordney-McCumber Tariff Act, signed September 21,
raised duties on hundreds of imported goods to some of the highest levels in
U.S. history, a policy meant to protect farmers and manufacturers still
adjusting to postwar prices. Labor tension flared even as prices fell.
Roughly half a million bituminous coal miners struck that April over wage
cuts employers had imposed as prices dropped, and hundreds of thousands of
railroad shop workers walked out in July in a separate dispute over pay and
work rules, together the largest strike wave since 1919. Both disputes
dragged on for months and drew federal mediation before ending without full
concessions for the workers. First-class postage remained at 2 cents.
