What happened to prices between 1941 and 1986
Between 1941 and 1986, the Consumer Price Index went from 14.7 to 109.6. Cumulatively, prices increased 645.6%, which works out to an average of 4.57% per year. Put differently, a dollar in 1941 bought what $0.13 buys in 1986.
Consumer prices rose 5.0% in 1941, up sharply from just 0.7% in 1940 and the fastest annual increase since 1920, as rearmament and Lend-Lease production pushed demand well ahead of peacetime supply even before the United States formally joined the war. Congress had already tilted the country away from neutrality that March, passing the Lend-Lease Act to arm Britain, and later the Soviet Union and other Allies, without requiring immediate payment. That April, the government created the Office of Price Administration to hold down the cost of civilian goods, the start of a price-control system that would keep official inflation numbers well below what wartime demand alone would have produced over the next four years. Then, on December 7, Japan attacked the naval base at Pearl Harbor, destroying much of the Pacific Fleet and killing more than 2,400 Americans. Congress declared war on Japan the next day and on Germany and Italy three days later, ending years of debate over whether the United States should stay out of the conflict spreading across Europe and Asia. Consumer prices, already up 48.5% from their 1913 level, would climb far faster over the next two years as the economy converted fully to war production. First-class postage held at 3 cents, and the minimum wage stayed at 30 cents an hour.
