What happened to prices between 1971 and 1979

Between 1971 and 1979, the Consumer Price Index went from 40.5 to 72.6. Cumulatively, prices increased 79.3%, which works out to an average of 7.57% per year. Put differently, a dollar in 1971 bought what $0.56 buys in 1979.

Consumer prices rose 4.4% in 1971, down from 1970’s 5.7% as the recession that started in December 1969 finally cooled demand. The bigger economic story came that August 15, when President Nixon closed the “gold window” that let foreign governments exchange dollars for gold, ending the Bretton Woods system that had anchored the dollar since World War II. The same address announced a 90-day freeze on wages and prices, the first peacetime controls the country had seen, an attempt to break inflationary expectations without the slower grind of tighter money. The “Nixon Shock,” as it came to be known, let the dollar float against other currencies for the first time and set the stage for a wage-and-price-control regime that would run in various forms into 1973. Politically, the country lowered its voting age that year: the 26th Amendment, ratified July 1, extended the vote to 18-year-olds, capping a campaign built on the argument that men old enough to be drafted to Vietnam were old enough to vote for the people who sent them. The Postal Service, independent since 1970’s reorganization, raised first-class postage from 6 to 8 cents that May. A median household earned $9,028 in 1971, up from $8,734 the year before, while gas held near 36 cents a gallon and a new home sold for a median $25,200. Consumer prices stood 309.1% above their 1913 level by year’s end, still years away from the double-digit inflation the controls were meant to prevent.

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.
