Value of $100 in 1929, adjusted to 1972

What happened to prices between 1929 and 1972

Between 1929 and 1972, the Consumer Price Index went from 17.1 to 41.8. Cumulatively, prices increased 144.4%, which works out to an average of 2.10% per year. Put differently, a dollar in 1929 bought what $0.41 buys in 1972.

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: 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.
