Value of $100 in 1920, adjusted to 1941

What happened to prices between 1920 and 1941

Between 1920 and 1941, the Consumer Price Index went from 20 to 14.7. Cumulatively, prices declined 26.5%, which works out to an average of -1.46% per year. Put differently, a dollar in 1920 bought what $1.36 buys in 1941.

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: 1941

Consumer prices rose 5.0% in 1941, up sharply from just 0.7% in 1940 and the fastest annual increase since 1920, as rearmament and Lend-Lease production pushed demand well ahead of peacetime supply even before the United States formally joined the war. Congress had already tilted the country away from neutrality that March, passing the Lend-Lease Act to arm Britain, and later the Soviet Union and other Allies, without requiring immediate payment. That April, the government created the Office of Price Administration to hold down the cost of civilian goods, the start of a price-control system that would keep official inflation numbers well below what wartime demand alone would have produced over the next four years. Then, on December 7, Japan attacked the naval base at Pearl Harbor, destroying much of the Pacific Fleet and killing more than 2,400 Americans. Congress declared war on Japan the next day and on Germany and Italy three days later, ending years of debate over whether the United States should stay out of the conflict spreading across Europe and Asia. Consumer prices, already up 48.5% from their 1913 level, would climb far faster over the next two years as the economy converted fully to war production. First-class postage held at 3 cents, and the minimum wage stayed at 30 cents an hour.
