What happened to prices between 1975 and 1979

Between 1975 and 1979, the Consumer Price Index went from 53.8 to 72.6. Cumulatively, prices increased 34.9%, which works out to an average of 7.78% per year. Put differently, a dollar in 1975 bought what $0.74 buys in 1979.

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: 1979

Consumer prices rose 11.3% in 1979, the fastest pace since 1947 and the decade’s second bout of double-digit inflation after 1974’s 11.0%. The trigger was familiar: the Iranian Revolution that January halted Iran’s oil exports, and panic buying amplified the shortage, sending crude prices sharply higher over the year and motorists back into gas lines, with some states reviving the odd-even rationing last seen in 1974. Paul Volcker, appointed Federal Reserve chairman that August, responded with a strategy shift announced that October: the Fed would target the money supply directly and let interest rates rise as high as necessary to break inflation, whatever the short-term cost. That cost would arrive as a deep recession in 1981-82, but by year’s end 1979 had already delivered enough turmoil on its own. A reactor at the Three Mile Island plant near Harrisburg, Pennsylvania, suffered a partial core meltdown that March 28, the worst commercial nuclear accident in U.S. history, and on November 4, militants in Tehran stormed the U.S. embassy and took 52 Americans hostage, beginning a 444-day crisis that consumed the rest of Carter’s presidency. A median household earned $16,461 in 1979, a new home sold for a median $62,900, and gas jumped to 86 cents a gallon. Consumer prices finished the decade 97.8% above where they stood in 1969, very nearly doubling in ten years, and stood 633.3% above their 1913 level. The 1970s had opened with inflation cooling from the 1969 spike and closed with prices rising faster than at any point since 1947, setting up the Great Inflation’s final act in 1980.
