Value of $100 in 1920, adjusted to 1968

What happened to prices between 1920 and 1968

Between 1920 and 1968, the Consumer Price Index went from 20 to 34.8. Cumulatively, prices increased 74.0%, which works out to an average of 1.16% per year. Put differently, a dollar in 1920 bought what $0.57 buys in 1968.

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: 1968

Consumer prices rose 4.2% in 1968, up sharply from 1967’s 3.1% and the fastest pace in 17 years, as Vietnam War spending and a tight labor market pushed inflation higher despite the Federal Reserve’s earlier tightening. The year was marked by political violence: Martin Luther King Jr. was assassinated on a motel balcony in Memphis on April 4, touching off rioting in more than 100 cities, and Robert F. Kennedy was shot in Los Angeles on June 5, moments after winning California’s Democratic presidential primary, and died the next day. Washington tried to answer the inflation problem directly that June 28, when Congress passed a 10% income tax surcharge, the Revenue and Expenditure Control Act, temporarily raising taxes and cutting spending to cool an economy overheated by war and Great Society outlays; prices kept accelerating anyway. The cost of living rose in smaller, more visible ways too: first-class postage climbed to 6 cents that January 7, and the minimum wage rose to $1.60 an hour that February 1, the final step of the increase Congress had set two years earlier. Consumer prices finished 1968 251.5% above their 1913 level.
