Value of $100 in 1920, adjusted to 1957

What happened to prices between 1920 and 1957

Between 1920 and 1957, the Consumer Price Index went from 20 to 28.1. Cumulatively, prices increased 40.5%, which works out to an average of 0.92% per year. Put differently, a dollar in 1920 bought what $0.71 buys in 1957.

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: 1957

Consumer prices rose 3.3% in 1957, up from 1956’s 1.5% and the sharpest increase since the Korean War price surge of 1951. The jump fed a growing debate among economists over “cost-push” inflation, prices climbing from rising wages and material costs rather than excess demand, a debate that would recur for the next quarter century. The Federal Reserve tightened policy to fight it, and by August the tighter money combined with falling business investment to tip the economy into a recession, according to the National Bureau of Economic Research’s dating. The Cold War took a technological turn that October, when the Soviet Union launched Sputnik, the first artificial satellite, on the 4th, stunning the American public and setting off both the Space Race and a surge in federal science and defense spending the following year. Civil rights reached a crisis that September in Little Rock, Arkansas: after Governor Orval Faubus used the National Guard to block nine Black students from Central High School, Eisenhower federalized the Guard and sent the 101st Airborne Division to enforce the Supreme Court’s desegregation order. Consumer prices finished 1957 183.8% above their 1913 level. First-class postage held at 3 cents, and the minimum wage stood at $1.00 an hour.
