Value of $100 in 1916, adjusted to 1930

What happened to prices between 1916 and 1930

Between 1916 and 1930, the Consumer Price Index went from 10.9 to 16.7. Cumulatively, prices increased 53.2%, which works out to an average of 3.09% per year. Put differently, a dollar in 1916 bought what $0.65 buys in 1930.

1916 was when World War I first showed up clearly in American price tags. Consumer prices rose 7.9% for the year, easily the sharpest increase since the Bureau of Labor Statistics’ CPI history begins in 1913, as factories ran flat out to fill steel, munitions, and food orders from Britain and France. Railroad workers felt the squeeze from rising living costs enough to threaten a nationwide strike; Congress headed it off in September with the Adamson Act, which set an eight-hour standard workday for interstate rail employees, the first federal law of its kind covering private-sector hours. Washington was also preparing more directly for war: the National Defense Act, signed in June, expanded the Army and National Guard and funded new government-owned munitions plants, adding another source of demand to an economy already running hot. Woodrow Wilson won re-election in November largely on having kept the country out of the fighting so far, a promise that would not survive the following spring. A first-class stamp still cost 2 cents, one of the few prices that had not yet moved.

The destination year: 1930

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.
