What happened to prices between 1921 and 1927

Between 1921 and 1927, the Consumer Price Index went from 17.9 to 17.4. Cumulatively, prices declined 2.8%, which works out to an average of -0.47% per year. Put differently, a dollar in 1921 bought what $1.03 buys in 1927.

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.

The destination year: 1927

Consumer prices fell 1.7% in 1927, a mild retreat after three years of gradual increases and part of a shallow up-and-down pattern that ran through the second half of the decade. Aviation delivered the year’s signature moment: Charles Lindbergh departed Roosevelt Field, New York, on May 20 and landed at Le Bourget Field outside Paris roughly 33.5 hours later, the first person to fly the Atlantic solo and nonstop. Detroit closed a chapter of its own that May, when Ford halted the Model T’s production line after nearly 19 years and more than 15 million cars sold, idling tens of thousands of workers while its factories retooled for the Model A. The Federal Reserve, meeting with European central bankers that summer, cut its discount rate to ease pressure on currencies still recovering from the war, a move later cited by economists including Milton Friedman and Anna Schwartz as fuel for the stock market speculation that built through the following two years.
