Between 1919 and 1948, the Consumer Price Index went from 17.3 to 24.1.
Cumulatively, prices increased 39.3%, which works out to an average of
1.15% per year. Put differently, a dollar in 1919 bought what
$0.72 buys in 1948.
The fighting in Europe ended in November 1918, but American prices kept
climbing through 1919 almost as fast as they had during the war itself,
rising 14.6% for the year. Wartime price and production controls were being
dismantled, millions of soldiers were returning to the civilian labor
market, and demand that had been held back for years ran into supply that
had not caught up, a combination that kept the cost of living rising even
with the guns silent. Workers, whose pay had fallen behind three straight
years of double-digit inflation, pushed back: a general strike shut down
Seattle in February, Boston’s police force walked out in September, and a
nationwide steel strike that same month drew in roughly 350,000 workers and
ran into the following January. One price did fall that year: first-class
postage reverted to 2 cents on July 1, ending the wartime 3-cent rate that
had funded part of the war effort since late 1917. By year’s end, prices had
risen close to 75% since the CPI’s 1913 starting point,
compressing more than a decade of typical peacetime inflation into six years
of war and its aftermath.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1919 spending costs in 1948, by category:
Category
Avg. yearly inflation
$100 in 1919 →
All items (CPI-U)
1.15%
$139
Food
1.18%
$140
Apparel
0.55%
$117
Not shown because the BLS began these indexes after 1919: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices rose 8.1% in 1948, down slightly from 1947’s
14.4% but still the second straight year of sharp postwar inflation now
that wartime price controls were fully gone. Congress moved to stabilize a
different economy that April, passing the Economic Cooperation Act to fund
the plan Secretary of State George Marshall had proposed the year before:
more than $13 billion over four years to rebuild Western Europe and counter
Soviet influence. The Cold War turned tense closer to the plan’s target
that June, when Soviet forces cut off road and rail access to the
Western-controlled sectors of Berlin. American and British aircraft
responded almost immediately with an airlift of food, fuel, and supplies
that would keep the city running for nearly a year. Domestic politics
produced its own upset that November: nearly every poll and pundit had
predicted a Republican win, but Harry Truman defeated New York Governor
Thomas Dewey, handing the Chicago Tribune its famously wrong “Dewey Defeats
Truman” headline. Consumer prices finished the year 143.4% above their
1913 level and 40.9% above 1929’s
pre-Depression peak. First-class postage held at 3 cents, and the minimum
wage stayed at 40 cents an hour.
