Value of $100 in 1917, adjusted to 1932

What happened to prices between 1917 and 1932

Between 1917 and 1932, the Consumer Price Index went from 12.8 to 13.7. Cumulatively, prices increased 7.0%, which works out to an average of 0.45% per year. Put differently, a dollar in 1917 bought what $0.93 buys in 1932.

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: 1932

Consumer prices fell 9.9% in 1932, the steepest single-year drop in the CPI’s history to that point and the third straight year of decline following 1930 and 1931. Wages, farm incomes, and industrial output all kept falling, and Congress tried to arrest the credit collapse by creating the Reconstruction Finance Corporation that January, capitalized at $500 million with authority to borrow up to $1.5 billion to lend directly to banks, railroads, and other struggling businesses. Relief did not reach ordinary households as quickly. That summer, tens of thousands of World War I veterans and their families camped in Washington demanding early payment of a service bonus not due until 1945; in July, U.S. Army troops under General Douglas MacArthur forcibly dispersed the encampment, an episode that badly damaged the Hoover administration’s standing months before an election it was already losing. Voters delivered their verdict on November 8, electing Franklin D. Roosevelt in a landslide over the incumbent Hoover on a promise of relief and a “new deal for the American people.” Roosevelt would not take office until the following March, leaving a long and difficult transition during the depths of the crisis. First-class postage rose from 2 cents to 3 cents on July 6, the first change to the rate since 1919.
