Between 1928 and 1947, the Consumer Price Index went from 17.1 to 22.3.
Cumulatively, prices increased 30.4%, which works out to an average of
1.41% per year. Put differently, a dollar in 1928 bought what
$0.77 buys in 1947.
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 1947, by category:
Category

All items (CPI-U)
1.41%

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 14.4% in 1947, up from 1946’s 8.3% and
the fastest annual increase since 1920, as the last of the wartime price
controls disappeared and a year of strikes, wage catch-up, and lingering
shortages hit consumers all at once. Congress answered the previous year’s
strike wave that June, overriding President Truman’s veto to pass the
Taft-Hartley Act, which banned secondary boycotts and the closed shop and
let states adopt “right-to-work” laws curbing union power. American
attention was also turning outward. In a June 5 speech at Harvard,
Secretary of State George Marshall outlined a U.S.-funded plan to rebuild
Western Europe’s economies, an effort that would become known as the
Marshall Plan once Congress funded it the following year. The government
reorganized itself for the confrontation with the Soviet Union that plan was
partly designed to prevent: the National Security Act, signed July 26,
created the Department of Defense, the Air Force as a separate service, the
Central Intelligence Agency, and the National Security Council. Consumer
prices stood 125.3% above their 1913 level and 30.4% above
1929’s pre-Depression peak, up from just 1.2% above it four
years earlier. First-class postage held at 3 cents, and the minimum wage
stayed at 40 cents an hour.
