Value of $100 in 1920, adjusted to 1942

What happened to prices between 1920 and 1942

Between 1920 and 1942, the Consumer Price Index went from 20 to 16.3. Cumulatively, prices declined 18.5%, which works out to an average of -0.93% per year. Put differently, a dollar in 1920 bought what $1.23 buys in 1942.

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: 1942

Consumer prices rose 10.9% in 1942, up from 1941’s already rapid 5.0% and the fastest increase since 1920, as the economy’s crash conversion to war production collided with shrinking supplies of civilian goods. The government tried to contain it: the General Maximum Price Regulation, effective May 18 and known as “General Max,” froze most retail prices at their highest March level, the broadest price control Washington had ever attempted. Rationing followed close behind. Sugar rationing began that May and gasoline rationing went nationwide in December, the leading edge of a system that would eventually cover meat, coffee, shoes, tires, and dozens of other goods before the war ended. The year’s other defining wartime measure had nothing to do with prices. Executive Order 9066, signed February 19, authorized the military to remove more than 110,000 Japanese Americans, most of them U.S. citizens, from the West Coast and hold them in inland internment camps for the war’s duration, one of the era’s starkest violations of civil liberties. Even with price controls in place, consumer prices climbed more than 10% for the first time since 1920, leaving the CPI 64.6% above its 1913 level. First-class postage held at 3 cents, and the minimum wage stayed at 30 cents an hour.
