What happened to prices between 1921 and 1936

Between 1921 and 1936, the Consumer Price Index went from 17.9 to 13.9. Cumulatively, prices declined 22.3%, which works out to an average of -1.67% per year. Put differently, a dollar in 1921 bought what $1.29 buys in 1936.

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: 1936

Consumer prices rose 1.5% in 1936, a third straight annual increase and part of a slow, steady climb back from the 1933 trough, though prices and the broader economy still had not fully recovered to their pre-Depression levels. Voters delivered their verdict on that recovery in November, reelecting Franklin D. Roosevelt over Republican Alf Landon in one of the most lopsided elections in U.S. history: Roosevelt carried 46 of 48 states and won the Electoral College 523 to 8, a broad public endorsement of the New Deal. Public works kept advancing that year, too. Hoover Dam, one of the era’s signature projects, had been dedicated in September 1935, but its first generators did not begin sending electricity over transmission lines to Los Angeles until October 1936, a milestone that showed how long even a celebrated project took to reach full operation. Consumer prices ended the year 40.4% above their 1913 level, still 18.7% below the 1929 peak, a gap that would keep narrowing until a sharp new recession interrupted the recovery the following year.
