Value of $100 in 1914, adjusted to 1939

What happened to prices between 1914 and 1939

Between 1914 and 1939, the Consumer Price Index went from 10 to 13.9. Cumulatively, prices increased 39.0%, which works out to an average of 1.33% per year. Put differently, a dollar in 1914 bought what $0.72 buys in 1939.

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: 1939

Consumer prices fell 1.4% in 1939, closing out a decade in which the CPI fell in six years and rose in four, leaving prices 18.7% below their 1929 level even after the mid-decade recovery. Measured against the start of the CPI’s modern record, prices still stood 40.4% above their 1913 level, a reminder that even a decade defined by deflation left the cost of living well above where it had been a generation earlier. The decade’s final months reset the economic picture entirely. Germany invaded Poland on September 1, and Britain and France declared war two days later; the United States stayed formally neutral under the Neutrality Acts, but Allied orders for war materiel began flowing to American factories almost immediately, a demand shock that would do more to end the Depression over the next few years than any peacetime relief program had managed. Domestic policy kept building on the New Deal’s framework, too: the federal minimum wage rose to 30 cents an hour that October, the second step in the schedule set by the 1938 Fair Labor Standards Act. Amid it all, the New York World’s Fair opened April 30 in Queens, themed “The World of Tomorrow” and drawing tens of millions of visitors with exhibits on television and other technologies promising a more prosperous decade than the one just ending. First-class postage held at 3 cents.
