Between 1930 and 1941, the Consumer Price Index went from 16.7 to 14.7.
Cumulatively, prices declined 12.0%, which works out to an average of
-1.15% per year. Put differently, a dollar in 1930 bought what
$1.14 buys in 1941.
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.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1930 spending costs in 1941, by category:
Category
Avg. yearly inflation
$100 in 1930 →
All items (CPI-U)
-1.15%
$88.02
Apparel
-0.54%
$94.21
Food
-1.58%
$83.97
Not shown because the BLS began these indexes after 1930: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices rose 5.0% in 1941, up sharply from just 0.7% in
1940 and the fastest annual increase since 1920, as
rearmament and Lend-Lease production pushed demand well ahead of peacetime
supply even before the United States formally joined the war. Congress had
already tilted the country away from neutrality that March, passing the
Lend-Lease Act to arm Britain, and later the Soviet Union and other Allies,
without requiring immediate payment. That April, the government created the
Office of Price Administration to hold down the cost of civilian goods, the
start of a price-control system that would keep official inflation numbers
well below what wartime demand alone would have produced over the next four
years. Then, on December 7, Japan attacked the naval base at Pearl Harbor,
destroying much of the Pacific Fleet and killing more than 2,400 Americans.
Congress declared war on Japan the next day and on Germany and Italy three
days later, ending years of debate over whether the United States should
stay out of the conflict spreading across Europe and Asia. Consumer prices,
already up 48.5% from their 1913 level, would climb far
faster over the next two years as the economy converted fully to war
production. First-class postage held at 3 cents, and the minimum wage stayed
at 30 cents an hour.
