What happened to prices between 1933 and 1940

Between 1933 and 1940, the Consumer Price Index went from 13 to 14. Cumulatively, prices increased 7.7%, which works out to an average of 1.06% per year. Put differently, a dollar in 1933 bought what $0.93 buys in 1940.

Consumer prices fell 5.1% in 1933, a smaller decline than 1932’s but enough to complete a four-year slide of 24.0% from the 1929 peak. The National Bureau of Economic Research dates the trough of that contraction to March 1933, closing out the longest downturn in its chronology, one that had run 43 months since August 1929. The bottom arrived alongside a change in government: Franklin D. Roosevelt was inaugurated March 4 and, within 48 hours, ordered every bank in the country closed to halt a fresh round of runs. Congress passed the Emergency Banking Act on March 9, letting solvent banks reopen under federal supervision, and the panic that had been building for months broke almost immediately. The administration moved on the currency next: Executive Order 6102, issued April 5, required Americans to turn in most gold coin, bullion, and certificates to the Federal Reserve, taking the country off the domestic gold standard (formal devaluation of the dollar followed the next January). Congress capped the year’s banking overhaul in June with the Banking Act of 1933, commonly called Glass-Steagall, which created the Federal Deposit Insurance Corporation and separated commercial banking from investment banking. Even after four straight years of falling prices, the CPI still stood 31.3% above its 1913 level. 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.
