Value of $100 in 1917, adjusted to 1933

What happened to prices between 1917 and 1933

Between 1917 and 1933, the Consumer Price Index went from 12.8 to 13. Cumulatively, prices increased 1.6%, which works out to an average of 0.10% per year. Put differently, a dollar in 1917 bought what $0.98 buys in 1933.

1917 is when World War I inflation stopped being a background trend and became the dominant fact of American economic life. Consumer prices rose 17.4% for the year, more than double the previous year’s already sharp increase, as the country’s April 6 entry into the war layered federal war spending on top of an economy already strained by military demand and worker shortages. Congress paid for the war with the War Revenue Act that October, which sharply raised income taxes, created a new tax on wartime business profits, and, in a small but very visible change for ordinary households, raised the cost of a first-class stamp from 2 cents to 3 cents that November, the rate’s first move since 1885. Herbert Hoover took over the new Food Administration in August and asked Americans to conserve food voluntarily rather than face formal rationing, a campaign that became famous enough that “Hooverize” entered the language as a verb for cutting back. None of it slowed prices much: the 17.4% increase would be topped again the very next year, in 1918.

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.
