What happened to prices between 1930 and 1978

Between 1930 and 1978, the Consumer Price Index went from 16.7 to 65.2. Cumulatively, prices increased 290.4%, which works out to an average of 2.88% per year. Put differently, a dollar in 1930 bought what $0.26 buys in 1978.

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: 1978

Consumer prices rose 7.6% in 1978, accelerating for a second straight year as rising wages, a weakening dollar, and climbing energy costs outpaced the Federal Reserve’s response. Fed chairman G. William Miller, appointed by Carter that March, kept interest rates too low to slow the trend, a policy later cited as one reason inflation kept building toward the following year’s crisis. California voters responded to their own version of the problem that June, passing Proposition 13 by nearly two to one to cap property tax rates after years of rising home values had pushed tax bills up alongside them. Foreign policy delivered one of the decade’s genuine breakthroughs: President Carter brought Egyptian President Anwar Sadat and Israeli Prime Minister Menachem Begin together for thirteen days of negotiations at Camp David that September, producing a framework for peace between the two countries that was signed as a treaty the following March. First-class postage rose to 15 cents that May 29, a rate that would hold longer than any other in the decade. The year ended in tragedy: cult leader Jim Jones directed the mass murder-suicide of more than 900 followers at a remote settlement in Guyana that November 18. A median household earned $15,064 in 1978, a new home sold for a median $55,700, and gas averaged 63 cents a gallon. Consumer prices stood 558.6% above their 1913 level, with the decade’s worst inflation still to come.
