Value of $100 in 1938, adjusted to 1940

What happened to prices between 1938 and 1940

Between 1938 and 1940, the Consumer Price Index went from 14.1 to 14. Cumulatively, prices declined 0.7%, which works out to an average of -0.36% per year. Put differently, a dollar in 1938 bought what $1.01 buys in 1940.

Consumer prices fell 2.1% in 1938, reversing most of 1937’s gain and interrupting four straight years of recovery from the Depression’s trough. The National Bureau of Economic Research dates the bottom of the downturn, which had begun that May, to June 1938, a sharp 13-month contraction that briefly pushed unemployment back up near 19%. Even in a year the economy was shrinking again, Congress passed one of the New Deal’s most lasting reforms. The Fair Labor Standards Act, signed June 25 and effective that October, established the first federal minimum wage, 25 cents an hour, capped the standard workweek at 44 hours with time-and-a-half overtime beyond it, and restricted the employment of children in most industries. The wage floor and hours limits applied only to workers engaged in interstate commerce at first, but they set a precedent that would expand in the decades that followed. Consumer prices stood 42.4% above their 1913 level and 17.5% below their 1929 peak, evidence of how far the recovery still had to go even eight years after 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.
