Between 1931 and 1938, the Consumer Price Index went from 15.2 to 14.1.
Cumulatively, prices declined 7.2%, which works out to an average of
-1.07% per year. Put differently, a dollar in 1931 bought what
$1.08 buys in 1938.
Consumer prices fell 9.0% in 1931, a sharp acceleration from the 2.3% decline
in 1930, as falling wages, collapsing farm prices, and a fresh
wave of bank failures fed a downward spiral that the still-contracting
economy could not shake. More than 2,000 banks failed during the year, far
more than in 1930, as depositors who had watched earlier banks go under
pulled their cash out of ones they feared were next. The crisis went
international that September, when Britain suspended the gold standard amid
a run on sterling. The Federal Reserve’s response made the domestic downturn
worse before it made anything better: to defend the dollar’s own gold
backing, the Fed raised its discount rate sharply that October, in two steps
from 1.5% to 3.5%, tightening credit at the exact moment the economy needed
the opposite. Not every headline that year was grim. The Empire State
Building opened its doors on May 1, briefly the tallest building in the
world, though so much of Manhattan’s office space sat vacant amid the
Depression that tenants stayed scarce and New Yorkers took to calling it the
“Empty State Building.” Consumer prices had now fallen for two straight
years and stood 53.5% above their 1913 level, down from the
68.7% margin of just twelve months before. First-class postage remained at 2
cents.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1931 spending costs in 1938, by category:
Category
Avg. yearly inflation

All items (CPI-U)
-1.07%

Consumer prices fell 2.1% in 1938, reversing most of 1937’s
gain and interrupting four straight years of recovery from the Depression’s
trough. The National Bureau of Economic Research dates the bottom of the
downturn, which had begun that May, to June 1938, a sharp 13-month
contraction that briefly pushed unemployment back up near 19%. Even in a
year the economy was shrinking again, Congress passed one of the New Deal’s
most lasting reforms. The Fair Labor Standards Act, signed June 25 and
effective that October, established the first federal minimum wage, 25
cents an hour, capped the standard workweek at 44 hours with time-and-a-half
overtime beyond it, and restricted the employment of children in most
industries. The wage floor and hours limits applied only to workers engaged
in interstate commerce at first, but they set a precedent that would expand
in the decades that followed. Consumer prices stood 42.4% above their
1913 level and 17.5% below their 1929 peak, evidence of how
far the recovery still had to go even eight years after the Depression
began. First-class postage held at 3 cents.
