Value of $100 in 1914, adjusted to 1940

What happened to prices between 1914 and 1940

Between 1914 and 1940, the Consumer Price Index went from 10 to 14. Cumulatively, prices increased 40.0%, which works out to an average of 1.30% per year. Put differently, a dollar in 1914 bought what $0.71 buys in 1940.

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: 1940

Consumer prices rose 0.7% in 1940, snapping 1939’s decline and marking the first increase since 1937. The gain was modest, and the CPI still stood 18.1% below its 1929 peak, a reminder of how far the recovery from the Depression’s trough had left to go even as defense orders from Britain and France began reaching American factories. War was already reshaping domestic policy well before it touched American soil. Congress passed the Selective Training and Service Act that September, the country’s first peacetime draft, requiring men aged 21 to 35 to register and authorizing the induction of up to 900,000 men a year, more than a year before Pearl Harbor. That November, Franklin Roosevelt won an unprecedented third term, defeating Republican Wendell Willkie after campaigning on keeping the United States out of the war then consuming Europe and Asia. The promise would not hold much longer: within two years, wartime demand would push consumer prices up faster than at any point since the aftermath of World War I. First-class postage held at 3 cents, and the federal minimum wage stayed at 30 cents an hour, the level set the previous October under the Fair Labor Standards Act.
