What happened to prices between 1918 and 1988

Between 1918 and 1988, the Consumer Price Index went from 15.1 to 118.3. Cumulatively, prices increased 683.4%, which works out to an average of 2.98% per year. Put differently, a dollar in 1918 bought what $0.13 buys in 1988: the 1918 dollar lost 87.2% of its purchasing power over these 70 years.

1918 brought the steepest annual price increase the CPI had recorded: consumer prices rose 18.0% for the year, edging out 1917’s already sharp 17.4% as the economy stayed at full wartime mobilization for most of the year. A first-class stamp cost 3 cents, up from 2 cents the previous November under the War Revenue Act’s wartime tax increases. The war itself ended on November 11, when Germany signed an armistice with the Allied powers after more than four years of fighting in Europe, but the inflation built up over a year and a half of mobilization did not disappear along with the fighting. The bigger public health story that year was the influenza pandemic that reached the U.S. in a mild spring wave and then returned that fall in a far deadlier form, eventually killing roughly 675,000 Americans, more than the country’s combat losses in the war. It hit factories, docks, and shops alongside households, adding disruption to an economy already strained by wartime demand. Prices would keep climbing even after the armistice, into the postwar surge of 1919.

The destination year: 1988

By 1988, the economic expansion that began in the ashes of the 1981-82 recession was in its sixth year, and the Federal Reserve was watching for signs it had run too long. Inflation rose to 4.1%, up from 3.6% the year before, while unemployment fell to its lowest level since 1974. Alan Greenspan’s Fed responded by raising the federal funds rate through the year, from about 6.5% to 8.5%, trying to cool demand before prices accelerated the way they had in the 1970s. Households still felt the difference between this expansion and the last one: gas held near 90 cents a gallon, almost exactly its 1987 price, and median household income rose to roughly $27,200. The one price that moved was postage, which rose from 22 to 25 cents in April, the fourth increase of the decade but a far gentler pace than the string of increases in the late 1970s and early 1980s. In November, Vice President George H.W. Bush won the presidency on the strength of the expansion, promising in his nomination speech to hold the line on taxes. Both the boom and that pledge would run into trouble within two years, as the Fed’s rate increases helped tip the economy toward the 1990-91 recession.
