Value of $100 in 1917, adjusted to 1956

What happened to prices between 1917 and 1956

Between 1917 and 1956, the Consumer Price Index went from 12.8 to 27.2. Cumulatively, prices increased 112.5%, which works out to an average of 1.95% per year. Put differently, a dollar in 1917 bought what $0.47 buys in 1956.

1917 is when World War I inflation stopped being a background trend and became the dominant fact of American economic life. Consumer prices rose 17.4% for the year, more than double the previous year’s already sharp increase, as the country’s April 6 entry into the war layered federal war spending on top of an economy already strained by military demand and worker shortages. Congress paid for the war with the War Revenue Act that October, which sharply raised income taxes, created a new tax on wartime business profits, and, in a small but very visible change for ordinary households, raised the cost of a first-class stamp from 2 cents to 3 cents that November, the rate’s first move since 1885. Herbert Hoover took over the new Food Administration in August and asked Americans to conserve food voluntarily rather than face formal rationing, a campaign that became famous enough that “Hooverize” entered the language as a verb for cutting back. None of it slowed prices much: the 17.4% increase would be topped again the very next year, in 1918.

The destination year: 1956

Consumer prices rose 1.5% in 1956, a return to mild inflation after they had fallen 0.4% in 1955, the only annual decline of the decade. The two years sat in the calmest stretch of the postwar index, a lull between the Korean War price surge earlier in the 1950s and the acceleration that would return in the 1970s. Congress had already raised the wage floor into that calm: the Fair Labor Standards Amendments of 1955, signed the previous August, took effect March 1 and lifted the federal minimum wage from 75 cents to $1 an hour, the first increase since 1950. Eisenhower signed a longer-lasting commitment on June 29, the Federal-Aid Highway Act, funding 41,000 miles of controlled-access highway at 90% federal cost to build the Interstate System, the largest public-works program the country had undertaken. He won a second term that November, carrying 41 states and about 57% of the popular vote in a rematch against Adlai Stevenson. Abroad, the Suez Crisis broke the calm on the supply side: Egypt nationalized the canal on July 26, and after Israel invaded the Sinai on October 29 with British and French forces following, the canal’s closure and damaged pipelines squeezed oil shipments to Western Europe for months. Consumer prices stood 174.7% above their 1913 level by 1956, up 94% since 1940 alone, even after a decade that had barely moved the index. First-class postage held at 3 cents, unchanged since 1932.
