What happened to prices between 1975 and 1978

Between 1975 and 1978, the Consumer Price Index went from 53.8 to 65.2. Cumulatively, prices increased 21.2%, which works out to an average of 6.62% per year. Put differently, a dollar in 1975 bought what $0.83 buys in 1978.

Consumer prices rose 9.1% in 1975, easing slightly from 1974’s 11.0% but still running far above anything the country had experienced before the decade began. The recession that started in November 1973, the deepest since the Great Depression, bottomed out that March, yet unemployment kept climbing through the year and touched 9%, a combination of high inflation and high joblessness that had no precedent in the postwar data. Vietnam ended that April 30, when North Vietnamese forces captured Saigon and the last Americans were evacuated by helicopter from the U.S. embassy roof. Fiscal strain hit closer to home too: New York City, facing bankruptcy after years of borrowing to paper over budget gaps, asked Washington for help that October. President Ford’s initial refusal produced the Daily News headline “Ford to City: Drop Dead,” though he ultimately signed a federal loan package that December. Amid the gloom, Bill Gates and Paul Allen founded Microsoft that April in Albuquerque, New Mexico, to sell a version of the BASIC programming language for the Altair 8800, one of the first personal computers sold to hobbyists. A median household earned $11,800 in 1975, a new home sold for a median $39,300, and first-class postage held at 10 cents, unchanged since 1974’s increase. Consumer prices stood 443.4% above their 1913 level, with the decade barely past its midpoint.

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.
