Between 1926 and 1939, the Consumer Price Index went from 17.7 to 13.9.
Cumulatively, prices declined 21.5%, which works out to an average of
-1.84% per year. Put differently, a dollar in 1926 bought what
$1.27 buys in 1939.
Consumer prices rose 1.1% in 1926, a third straight year of mild inflation
and part of the price stability that defined the middle of the decade.
Florida’s real estate boom, which had peaked the previous year on
speculative buying of undeveloped land, ended abruptly that September when
the Great Miami Hurricane made landfall near the city, killing hundreds and
wrecking the market for land whose value had rested on continued
speculation rather than anything underneath it. In Detroit, Henry Ford moved
his company to a five-day, 40-hour work week without cutting pay, a break
from the standard six-day schedule that other large employers would
gradually adopt over the following decades; Ford argued publicly that
workers with more leisure time would also become better customers for the
cars his factories built. Consumer prices remained low enough by historical
standards that a first-class stamp still cost just 2 cents, the same price
it had held since mid-1919.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1926 spending costs in 1939, by category:
Category
Avg. yearly inflation
$100 in 1926 →
All items (CPI-U)
-1.84%
$78.53
Apparel
-1.39%
$83.40
Food
-2.77%
$69.41
Not shown because the BLS began these indexes after 1926: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices fell 1.4% in 1939, closing out a decade in which the CPI
fell in six years and rose in four, leaving prices 18.7% below their
1929 level even after the mid-decade recovery. Measured
against the start of the CPI’s modern record, prices still stood 40.4%
above their 1913 level, a reminder that even a decade defined
by deflation left the cost of living well above where it had been a
generation earlier. The decade’s final months reset the economic picture
entirely. Germany invaded Poland on September 1, and Britain and France
declared war two days later; the United States stayed formally neutral
under the Neutrality Acts, but Allied orders for war materiel began flowing
to American factories almost immediately, a demand shock that would do more
to end the Depression over the next few years than any peacetime relief
program had managed. Domestic policy kept building on the New Deal’s
framework, too: the federal minimum wage rose to 30 cents an hour that
October, the second step in the schedule set by the 1938 Fair Labor
Standards Act. Amid it all, the New York World’s Fair opened April 30 in
Queens, themed “The World of Tomorrow” and drawing tens of millions of
visitors with exhibits on television and other technologies promising a
more prosperous decade than the one just ending. First-class postage held
at 3 cents.
