What happened to prices between 1931 and 1951

Between 1931 and 1951, the Consumer Price Index went from 15.2 to 26. Cumulatively, prices increased 71.1%, which works out to an average of 2.72% per year. Put differently, a dollar in 1931 bought what $0.58 buys in 1951.

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 destination year: 1951

Consumer prices rose 7.9% in 1951, up sharply from 1950’s 1.3% and the fastest increase since 1947, as Korean War buying and a defense spending surge hit an economy still adjusting to peacetime. Much of the jump came early in the year, before the government stepped in: the Office of Price Stabilization imposed a general ceiling on prices January 26, and the Wage Stabilization Board froze wages soon after, the broadest peacetime controls since the war began that June. The year’s more lasting change came in monetary policy. On March 4, the Treasury and the Federal Reserve signed the Accord, ending the Fed’s wartime obligation to hold down interest rates on government bonds and freeing the central bank to fight inflation on its own terms for the first time since 1942, a shift that would shape Fed independence for decades. Congress raised taxes that October to help pay for the war: the Revenue Act of 1951, signed October 20, lifted individual and corporate income taxes along with a range of excise taxes, the third increase in taxes since fighting began in Korea. Consumer prices finished 1951 162.6% above their 1913 level. First-class postage held at 3 cents, and the minimum wage stayed at 75 cents an hour.
