Between 1926 and 1930, the Consumer Price Index went from 17.7 to 16.7.
Cumulatively, prices declined 5.6%, which works out to an average of
-1.44% per year. Put differently, a dollar in 1926 bought what
$1.06 buys in 1930.
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 1930, by category:
Category
Avg. yearly inflation
$100 in 1926 →
All items (CPI-U)
-1.44%
$94.35
Apparel
-1.68%
$93.44
Food
-2.13%
$91.76
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 2.3% in 1930, a mild decline compared with what was
coming but the first sign that the summer 1929 downturn was not going to be
short. The National Bureau of Economic Research dates that contraction from
August 1929, and by the time it finally bottomed out in March 1933 it would
run 43 months, the longest of any downturn in the NBER’s chronology back to
1854. Congress made the trade picture worse in June, when President Hoover
signed the Smoot-Hawley Tariff Act, raising duties on more than 20,000
imported goods to some of the highest levels in a century. Trading partners
retaliated with tariffs of their own, and global trade volumes collapsed
over the next several years, deepening a downturn economists still debate
how much the tariff itself worsened. The financial system cracked that fall:
a regional banking panic culminated in the December 11 failure of the Bank
of United States in New York, at the time the largest bank failure in
American history, wiping out more than $200 million in deposits. It was the
first of four banking panics that would hit the country before 1933 was
out. Consumer prices still stood 68.7% above their 1913
starting point, but the direction had clearly turned. First-class postage
held at 2 cents, unchanged for eleven straight years.
