What happened to prices between 1930 and 1933

Between 1930 and 1933, the Consumer Price Index went from 16.7 to 13. Cumulatively, prices declined 22.2%, which works out to an average of -8.01% per year. Put differently, a dollar in 1930 bought what $1.28 buys in 1933.

Consumer prices fell 2.3% in 1930, a mild decline compared with what was coming but the first sign that the summer 1929 downturn was not going to be short. The National Bureau of Economic Research dates that contraction from August 1929, and by the time it finally bottomed out in March 1933 it would run 43 months, the longest of any downturn in the NBER’s chronology back to 1854. Congress made the trade picture worse in June, when President Hoover signed the Smoot-Hawley Tariff Act, raising duties on more than 20,000 imported goods to some of the highest levels in a century. Trading partners retaliated with tariffs of their own, and global trade volumes collapsed over the next several years, deepening a downturn economists still debate how much the tariff itself worsened. The financial system cracked that fall: a regional banking panic culminated in the December 11 failure of the Bank of United States in New York, at the time the largest bank failure in American history, wiping out more than $200 million in deposits. It was the first of four banking panics that would hit the country before 1933 was out. Consumer prices still stood 68.7% above their 1913 starting point, but the direction had clearly turned. First-class postage held at 2 cents, unchanged for eleven straight years.

The destination year: 1933

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.
