Value of $100 in 1934, adjusted to 1940

What happened to prices between 1934 and 1940

Between 1934 and 1940, the Consumer Price Index went from 13.4 to 14. Cumulatively, prices increased 4.5%, which works out to an average of 0.73% per year. Put differently, a dollar in 1934 bought what $0.96 buys in 1940.

Consumer prices rose 3.1% in 1934, the first annual increase since 1926; every year from 1927 through 1933 had been flat or falling, so the turn marked a real break after eight years without a single gain. Currency policy did some of the work. The Gold Reserve Act, signed January 30, formally devalued the dollar by raising the official price of gold from $20.67 to $35 an ounce, part of the administration’s deliberate effort to reflate prices after four straight years of deflation. Financial regulation tightened at the same time: the Securities Exchange Act of June 6 created the Securities and Exchange Commission to police stock exchanges and enforce disclosure rules, a direct response to the speculation blamed for the 1929 crash. The recovery was fragile and unevenly felt, especially on the Great Plains, where drought had turned overplowed farmland to dust. Over May 9-11, high winds lifted an estimated 350 million tons of topsoil into the air, darkening skies as far away as Washington and New York and giving city readers who had never seen a wheat field a first glimpse of the disaster building in Kansas, Oklahoma, and Texas. Consumer prices stood 35.4% above their 1913 level, still well below the 1929 peak but rising for the first time since the Depression began. First-class postage held at 3 cents.

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.
