Between 1920 and 1932, the Consumer Price Index went from 20 to 13.7.
Cumulatively, prices declined 31.5%, which works out to an average of
-3.10% per year. Put differently, a dollar in 1920 bought what
$1.46 buys in 1932.
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 1932, by category:
Category
Avg. yearly inflation
$100 in 1920 →
All items (CPI-U)
-3.10%
$68.50
Food
-5.46%
$50.95
Apparel
-6.40%
$45.24
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 9.9% in 1932, the steepest single-year drop in the
CPI’s history to that point and the third straight year of decline following
1930 and 1931. Wages, farm incomes, and
industrial output all kept falling, and Congress tried to arrest the credit
collapse by creating the Reconstruction Finance Corporation that January,
capitalized at $500 million with authority to borrow up to $1.5 billion to
lend directly to banks, railroads, and other struggling businesses. Relief
did not reach ordinary households as quickly. That summer, tens of thousands
of World War I veterans and their families camped in Washington demanding
early payment of a service bonus not due until 1945; in July, U.S. Army
troops under General Douglas MacArthur forcibly dispersed the encampment, an
episode that badly damaged the Hoover administration’s standing months
before an election it was already losing. Voters delivered their verdict on
November 8, electing Franklin D. Roosevelt in a landslide over the
incumbent Hoover on a promise of relief and a “new deal for the American
people.” Roosevelt would not take office until the following March, leaving
a long and difficult transition during the depths of the crisis. First-class
postage rose from 2 cents to 3 cents on July 6, the first change to the rate
since 1919.
