What happened to prices between 1939 and 1946

Between 1939 and 1946, the Consumer Price Index went from 13.9 to 19.5. Cumulatively, prices increased 40.3%, which works out to an average of 4.95% per year. Put differently, a dollar in 1939 bought what $0.71 buys in 1946.

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: 1946

Consumer prices rose 8.3% in 1946, up sharply from 1945’s 2.3% and the sharpest increase since 1942, as wartime price controls finally came apart. Congress let the Office of Price Administration’s authority lapse at the end of June, reinstated a weaker version soon after, then wound the whole system down through the rest of the year, releasing years of pent-up demand into the price level almost at once. Meat was the clearest casualty of the fight over decontrol: farmers withheld livestock rather than sell at capped prices, producing severe shortages that spring and summer until ceilings on meat were lifted that October, after which supplies reappeared almost overnight. Labor cashed in its own wartime restraint the same year. An estimated 4.6 million workers walked out at some point in 1946, hitting steel, coal, automakers, and the railroads in the largest strike wave in U.S. history, as unions pushed for wage gains to offset cost-of-living increases controls could no longer contain. Amid the turmoil, Congress made a less visible but lasting change to economic policy: the Employment Act of 1946, signed that February, committed the federal government to promoting maximum employment and created the Council of Economic Advisers. Consumer prices stood 97.0% above their 1913 level, nearly double where the index had started 33 years earlier. First-class postage held at 3 cents, and the minimum wage stayed at 40 cents an hour.
