Value of $100 in 1930, adjusted to 1972

What happened to prices between 1930 and 1972

Between 1930 and 1972, the Consumer Price Index went from 16.7 to 41.8. Cumulatively, prices increased 150.3%, which works out to an average of 2.21% per year. Put differently, a dollar in 1930 bought what $0.40 buys in 1972.

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: 1972

Consumer prices rose just 3.2% in 1972, the calmest year of the decade and a sharp break from the previous two years. The relief was largely engineered: Nixon’s wage and price controls, imposed as a 90-day freeze in August 1971, had settled into a series of “phases” that capped how much businesses could raise prices through the election year. Economists would later argue the controls mostly deferred inflation rather than curing it, storing up pressure that broke loose once they were lifted. Nixon spent political capital on foreign policy that year, traveling to Beijing that February in the first visit by a sitting U.S. president to the People’s Republic of China, a trip that began normalizing relations Washington had frozen since 1949. Closer to home, five men were arrested breaking into the Democratic National Committee’s offices at the Watergate complex that June 17, an event that drew little attention at the time but would eventually force Nixon from office. None of it dented his re-election bid: Nixon carried 49 states against Democrat George McGovern that November, helped by an economy that, on paper, looked more stable than it had in years. A median household earned $9,697 in 1972, a new home sold for a median $27,600, and gas held near 36 cents a gallon for a third straight year. Consumer prices stood 322.2% above their 1913 level, a lull that would not survive contact with the controls’ expiration and the oil shock still to come.
