What happened to prices between 1923 and 1990

Between 1923 and 1990, the Consumer Price Index went from 17.1 to 130.7. Cumulatively, prices increased 664.3%, which works out to an average of 3.08% per year. Put differently, a dollar in 1923 bought what $0.13 buys in 1990.

Consumer prices rose 1.8% in 1923, the first increase since 1920 and a sign the postwar deflation had run its course; the economy settled into the steadier growth that defined much of the rest of the decade. The year’s biggest shock was political rather than economic: Warren Harding died August 2 in San Francisco while returning from a trip to Alaska, and Vice President Calvin Coolidge was sworn in the next day at his family’s farmhouse in Plymouth Notch, Vermont, administered the oath of office by his own father, a notary public, by lamplight. Coolidge would go on to preside over the low, stable inflation of the “Roaring Twenties.” The contrast with Germany that year was stark. The Weimar Republic’s currency collapse reached its peak in November 1923, with prices doubling every few days and a loaf of bread costing billions of marks; Germany introduced a new currency, the Rentenmark, that month to halt the spiral. U.S. consumer prices, by comparison, had moved in single digits or held flat every year since 1921, a gap that shaped how American economists would later think about what made the postwar inflation of Europe so different from the mild swings at home. First-class postage stayed at 2 cents.

The destination year: 1990

In 1990, the median U.S. household earned about $29,900, gas averaged $1.15 a gallon, and mailing a letter cost a quarter. Inflation ran hot at 5.4% for the year, its highest rate since 1982, pushed up by an oil shock after Iraq’s invasion of Kuwait, and the economy tipped into recession that summer. It was the last gasp of elevated inflation before the long calm of the 1990s.
