Value of $100 in 1917, adjusted to 1951

What happened to prices between 1917 and 1951

Between 1917 and 1951, the Consumer Price Index went from 12.8 to 26. Cumulatively, prices increased 103.1%, which works out to an average of 2.11% per year. Put differently, a dollar in 1917 bought what $0.49 buys in 1951.

1917 is when World War I inflation stopped being a background trend and became the dominant fact of American economic life. Consumer prices rose 17.4% for the year, more than double the previous year’s already sharp increase, as the country’s April 6 entry into the war layered federal war spending on top of an economy already strained by military demand and worker shortages. Congress paid for the war with the War Revenue Act that October, which sharply raised income taxes, created a new tax on wartime business profits, and, in a small but very visible change for ordinary households, raised the cost of a first-class stamp from 2 cents to 3 cents that November, the rate’s first move since 1885. Herbert Hoover took over the new Food Administration in August and asked Americans to conserve food voluntarily rather than face formal rationing, a campaign that became famous enough that “Hooverize” entered the language as a verb for cutting back. None of it slowed prices much: the 17.4% increase would be topped again the very next year, in 1918.

The destination year: 1951

Consumer prices rose 7.9% in 1951, up sharply from 1950’s 1.3% and the fastest increase since 1947, as Korean War buying and a defense spending surge hit an economy still adjusting to peacetime. Much of the jump came early in the year, before the government stepped in: the Office of Price Stabilization imposed a general ceiling on prices January 26, and the Wage Stabilization Board froze wages soon after, the broadest peacetime controls since the war began that June. The year’s more lasting change came in monetary policy. On March 4, the Treasury and the Federal Reserve signed the Accord, ending the Fed’s wartime obligation to hold down interest rates on government bonds and freeing the central bank to fight inflation on its own terms for the first time since 1942, a shift that would shape Fed independence for decades. Congress raised taxes that October to help pay for the war: the Revenue Act of 1951, signed October 20, lifted individual and corporate income taxes along with a range of excise taxes, the third increase in taxes since fighting began in Korea. Consumer prices finished 1951 162.6% above their 1913 level. First-class postage held at 3 cents, and the minimum wage stayed at 75 cents an hour.
