Value of $100 in 1956, adjusted to 1978

What happened to prices between 1956 and 1978

Between 1956 and 1978, the Consumer Price Index went from 27.2 to 65.2. Cumulatively, prices increased 139.7%, which works out to an average of 4.05% per year. Put differently, a dollar in 1956 bought what $0.42 buys in 1978.

Consumer prices rose 1.5% in 1956, a return to mild inflation after they had fallen 0.4% in 1955, the only annual decline of the decade. The two years sat in the calmest stretch of the postwar index, a lull between the Korean War price surge earlier in the 1950s and the acceleration that would return in the 1970s. Congress had already raised the wage floor into that calm: the Fair Labor Standards Amendments of 1955, signed the previous August, took effect March 1 and lifted the federal minimum wage from 75 cents to $1 an hour, the first increase since 1950. Eisenhower signed a longer-lasting commitment on June 29, the Federal-Aid Highway Act, funding 41,000 miles of controlled-access highway at 90% federal cost to build the Interstate System, the largest public-works program the country had undertaken. He won a second term that November, carrying 41 states and about 57% of the popular vote in a rematch against Adlai Stevenson. Abroad, the Suez Crisis broke the calm on the supply side: Egypt nationalized the canal on July 26, and after Israel invaded the Sinai on October 29 with British and French forces following, the canal’s closure and damaged pipelines squeezed oil shipments to Western Europe for months. Consumer prices stood 174.7% above their 1913 level by 1956, up 94% since 1940 alone, even after a decade that had barely moved the index. First-class postage held at 3 cents, unchanged since 1932.

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.
