Between 1931 and 1977, the Consumer Price Index went from 15.2 to 60.6.
Cumulatively, prices increased 298.7%, which works out to an average of
3.05% per year. Put differently, a dollar in 1931 bought what
$0.25 buys in 1977.
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 1977, by category:

The destination year: 1977
Consumer prices rose 6.5% in 1977, ticking back up from 1976’s
5.8% as the economic recovery strengthened, wages climbed, and energy costs
pushed higher again. The year opened with a warning about that energy
dependence: record cold across the Midwest and Northeast in January and
February strained natural gas supplies so badly that schools and factories in
several states shut down for days to conserve fuel. Jimmy Carter, inaugurated
that January, made energy policy a centerpiece of his presidency, and
Congress created the cabinet-level Department of Energy that August to
consolidate programs built up piecemeal since the 1973 oil embargo. Culture
offered some relief from the anxiety: released that May, Star Wars became the
highest-grossing film in history to that point, drawing lines around theater
blocks for months. The year also closed an era in a different way. Elvis
Presley was found dead at his Graceland home on August 16 at age 42, drawing
tens of thousands of mourners to Memphis. A median household earned $13,572
in 1977, a new home sold for a median $48,800, and gas averaged 62 cents a
gallon. Consumer prices stood 512.1% above their 1913 level,
with the energy anxieties of the year setting up the harder shocks of 1978
and 1979.
