What happened to prices between 1921 and 1951

Between 1921 and 1951, the Consumer Price Index went from 17.9 to 26. Cumulatively, prices increased 45.3%, which works out to an average of 1.25% per year. Put differently, a dollar in 1921 bought what $0.69 buys in 1951.

Consumer prices fell 10.5% in 1921, the mirror image of the wartime inflation that had more than doubled the cost of living between 1913 and 1920. The Depression of 1920-21, one of the sharpest contractions in U.S. history, bottomed out that July according to the National Bureau of Economic Research, even though it had lasted barely eighteen months. Unemployment climbed toward one worker in ten as businesses cut production and prices to work through wartime inventories, but the same collapse in prices also meant the recovery, once it started, had room to run without reigniting inflation. Warren Harding took office March 4, promising a return to “normalcy” after a decade of war, pandemic, labor unrest, and rapid price swings; his administration moved quickly to cut top income tax rates and federal spending. Congress also acted on immigration that year: the Emergency Quota Act, signed May 19, capped annual arrivals from each country at 3% of that nationality’s population in the 1910 census, the first time the United States had set a numerical ceiling on immigration. The law favored northern and western Europe and cut total immigration by more than half compared with prewar levels; Congress tightened the formula again in 1924. 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.
