Value of $100 in 1929, adjusted to 1942

What happened to prices between 1929 and 1942

Between 1929 and 1942, the Consumer Price Index went from 17.1 to 16.3. Cumulatively, prices declined 4.7%, which works out to an average of -0.37% per year. Put differently, a dollar in 1929 bought what $1.05 buys in 1942.

Consumer prices were unchanged in 1929, the CPI’s annual average flat for the second time in six years and a fitting close to a decade that began with wartime inflation and ended in rough price stability. By year’s end the index stood 14.5% below its 1920 peak and roughly 73% above its 1913 starting point, a reminder that even a “stable” decade left prices well above where they had started. The stability in the cost of living masked what was building in financial markets. The National Bureau of Economic Research dates the start of the Great Depression to that August, the month the business cycle peaked, months before most Americans noticed anything was wrong. The break came that October: panic selling hit Wall Street on Black Thursday, October 24, and returned even worse on Black Tuesday, October 29, when the Dow Jones Industrial Average fell about 12% in a single session. Billions of dollars in paper wealth disappeared within days, and the crash marked the start of a downturn that would pull consumer prices into their steepest sustained decline of the 20th century over the next four years. First-class postage was still 2 cents, a price that would hold until 1932.

The destination year: 1942

Consumer prices rose 10.9% in 1942, up from 1941’s already rapid 5.0% and the fastest increase since 1920, as the economy’s crash conversion to war production collided with shrinking supplies of civilian goods. The government tried to contain it: the General Maximum Price Regulation, effective May 18 and known as “General Max,” froze most retail prices at their highest March level, the broadest price control Washington had ever attempted. Rationing followed close behind. Sugar rationing began that May and gasoline rationing went nationwide in December, the leading edge of a system that would eventually cover meat, coffee, shoes, tires, and dozens of other goods before the war ended. The year’s other defining wartime measure had nothing to do with prices. Executive Order 9066, signed February 19, authorized the military to remove more than 110,000 Japanese Americans, most of them U.S. citizens, from the West Coast and hold them in inland internment camps for the war’s duration, one of the era’s starkest violations of civil liberties. Even with price controls in place, consumer prices climbed more than 10% for the first time since 1920, leaving the CPI 64.6% above its 1913 level. First-class postage held at 3 cents, and the minimum wage stayed at 30 cents an hour.
