Value of $100 in 1913, adjusted to 1930

What happened to prices between 1913 and 1930

Between 1913 and 1930, the Consumer Price Index went from 9.9 to 16.7. Cumulatively, prices increased 68.7%, which works out to an average of 3.12% per year. Put differently, a dollar in 1913 bought what $0.59 buys in 1930.

1913 is where this site’s price history begins, because it’s where the Bureau of Labor Statistics’ own consumer price data begins. The CPI wasn’t published in real time back then; the BLS built the earliest index retroactively from retail price records collected starting in 1913, which makes every dollar figure on this site ultimately anchored to that year’s prices. It was also the year the machinery of modern federal economic policy was built. The 16th Amendment, ratified in February, cleared the constitutional path for a federal income tax, and the Revenue Act that followed in October imposed a top rate of just 7% on income above $500,000, a narrow tax that would later be reshaped into the broad-based system that funds the government today. In December, Congress passed the Federal Reserve Act, creating the central bank that would eventually take on fighting inflation as one of its core jobs, including the 19%-plus interest rates it deployed against the 1970s and early 1980s price surge. Consumer life in 1913 was correspondingly simple by later standards: a first-class stamp cost 2 cents, a price that held from 1885 all the way to 1917, and the Ford Motor Company introduced the moving assembly line at its Highland Park plant that year, a manufacturing breakthrough that would spend the next decade driving down the cost of a car faster than prices elsewhere were rising.

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.
