What happened to prices between 1978 and 1981

Between 1978 and 1981, the Consumer Price Index went from 65.2 to 90.9. Cumulatively, prices increased 39.4%, which works out to an average of 11.71% per year. Put differently, a dollar in 1978 bought what $0.72 buys in 1981.

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.

The destination year: 1981

1981 was the year the inflation fever finally broke, at an extraordinary price. Consumer prices rose 10.3%, the second year of back-to-back double-digit inflation and the last time the U.S. would see one. To end it, Paul Volcker’s Federal Reserve drove its policy rate above 19% and let borrowing costs go where they may: a 30-year mortgage cost more than 18% by autumn, car loans and business credit froze, and homebuilders mailed the Fed two-by-fours in protest. The squeeze tipped the economy into recession in July, the deep 1981–82 downturn that would push unemployment past 10%. But it worked. Inflation fell by nearly half within a year and to under 4% by 1983, the disinflation that defined the following two decades. Even the price of mailing a letter told the year’s story: postage went up twice in eight months.
