What happened to prices between 1939 and 1974

Between 1939 and 1974, the Consumer Price Index went from 13.9 to 49.3. Cumulatively, prices increased 254.7%, which works out to an average of 3.68% per year. Put differently, a dollar in 1939 bought what $0.28 buys in 1974.

Consumer prices fell 1.4% in 1939, closing out a decade in which the CPI fell in six years and rose in four, leaving prices 18.7% below their 1929 level even after the mid-decade recovery. Measured against the start of the CPI’s modern record, prices still stood 40.4% above their 1913 level, a reminder that even a decade defined by deflation left the cost of living well above where it had been a generation earlier. The decade’s final months reset the economic picture entirely. Germany invaded Poland on September 1, and Britain and France declared war two days later; the United States stayed formally neutral under the Neutrality Acts, but Allied orders for war materiel began flowing to American factories almost immediately, a demand shock that would do more to end the Depression over the next few years than any peacetime relief program had managed. Domestic policy kept building on the New Deal’s framework, too: the federal minimum wage rose to 30 cents an hour that October, the second step in the schedule set by the 1938 Fair Labor Standards Act. Amid it all, the New York World’s Fair opened April 30 in Queens, themed “The World of Tomorrow” and drawing tens of millions of visitors with exhibits on television and other technologies promising a more prosperous decade than the one just ending.

The destination year: 1974

1974 was the year the postwar economy broke its old rules. Consumer prices rose 11.0%, the fastest annual increase since 1947, as the Arab oil embargo that ran from October 1973 to March 1974 roughly quadrupled the price of crude oil worldwide. Gasoline, which had averaged 38.5 cents a gallon in 1973, jumped to 53.2 cents, and shortages forced many states into odd-even rationing at the pump. Nixon’s wage and price controls, in place in some form since 1971, expired at the end of April, removing the last brake on prices just as the oil shock hit. Nixon himself resigned in August over Watergate, and Gerald Ford’s response to inflation, a voluntary “Whip Inflation Now” campaign built around lapel buttons, became a symbol of how little conventional politics could do against the problem. Prices kept climbing even as the economy weakened: a recession that started in November 1973 dragged on, the Dow fell to a bear-market bottom of 577.60 in December, and unemployment was already rising toward the 9% it would reach in 1975. The combination of rising prices and a shrinking economy gave the decade its name: stagflation.
