Value of $100 in 1914, adjusted to 1917

What happened to prices between 1914 and 1917

Between 1914 and 1917, the Consumer Price Index went from 10 to 12.8. Cumulatively, prices increased 28.0%, which works out to an average of 8.58% per year. Put differently, a dollar in 1914 bought what $0.78 buys in 1917.

Consumer prices barely moved in 1914, rising just 1.0% for the year, even as the country’s financial plumbing was rebuilt from the ground up. The Federal Reserve Banks, created by the Federal Reserve Act signed the previous December, opened their doors on November 16, giving the U.S. a central bank for the first time since the 1830s. Weeks earlier, the outbreak of war in Europe had spooked the New York Stock Exchange into closing for more than four months, the longest shutdown in its history, as officials worried European investors would dump American securities for gold. Domestically, the bigger story was labor: Henry Ford’s decision to pay factory workers $5 a day, announced in January, roughly doubled wages on his assembly lines and pushed other manufacturers to raise pay just to keep workers from leaving. A first-class stamp still cost 2 cents, a price that had held since 1885 and would keep holding for three more years, even as the war reshaping Europe began pulling the American economy toward the sustained wartime inflation of 1917.

The destination year: 1917

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.
