What happened to prices between 1920 and 1951

Between 1920 and 1951, the Consumer Price Index went from 20 to 26. Cumulatively, prices increased 30.0%, which works out to an average of 0.85% per year. Put differently, a dollar in 1920 bought what $0.77 buys in 1951.

1920 was the last year of the inflation that had built since the war began: consumer prices rose 15.6% for the year, leaving the CPI more than double its 1913 starting level after seven straight years of increases. The boom behind those increases turned to bust before the year was over. The Federal Reserve, worried about speculation, pushed its discount rate to a record 7% that spring, and wholesale prices, which had led the wartime runup, began collapsing within months. The National Bureau of Economic Research dates the resulting downturn from January 1920 to July 1921, one of the shortest but steepest contractions in U.S. history, and consumer prices followed into outright decline, falling 10.5% in 1921. Two constitutional changes reshaped the country that year, too. The 18th Amendment’s ban on alcohol took legal effect January 17, enforced under the Volstead Act Congress had passed the previous October. Then, on August 18, Tennessee’s ratification of the 19th Amendment secured women’s right to vote nationwide, and women cast ballots in a presidential election for the first time that November, when Warren Harding won on a promise to return the country to “normalcy” after a decade of war, pandemic, and rising prices. First-class postage held at 2 cents, unchanged since mid-1919.

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.
