Between 1928 and 1948, the Consumer Price Index went from 17.1 to 24.1.
Cumulatively, prices increased 40.9%, which works out to an average of
1.73% per year. Put differently, a dollar in 1928 bought what
$0.71 buys in 1948.
Consumer prices fell 1.7% in 1928, the second straight year of mild decline
even as the stock market climbed sharply, a widening gap between asset
prices and the cost of living that later economists pointed to as an early
warning sign. The Federal Reserve tightened policy repeatedly over the year,
raising its discount rate in an effort to slow the flood of borrowed money
pouring into stock purchases without derailing the broader economy, a
balancing act it ultimately failed to manage. Herbert Hoover won the
presidential election that November, defeating Democrat Al Smith on a
platform built around continuing the prosperity of the Coolidge years; few
voters or policymakers anticipated how quickly that prosperity would end.
First-class postage remained at 2 cents, a price that had now held for nine
straight years.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1928 spending costs in 1948, by category:
Category
Avg. yearly inflation
$100 in 1928 →
All items (CPI-U)
1.73%
$141
Apparel
2.69%
$170
Food
2.38%
$160
Not shown because the BLS began these indexes after 1928: 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.
