Value of $100 in 1924, adjusted to 1929

What happened to prices between 1924 and 1929

Between 1924 and 1929, the Consumer Price Index went from 17.1 to 17.1. Cumulatively, prices increased 0.0%, which works out to an average of 0.00% per year. Put differently, a dollar in 1924 bought what $1.00 buys in 1929.

Consumer prices held flat in 1924, the CPI’s annual average unchanged from 1923 after swinging from a sharp postwar drop to a modest rise the year before. That stability, extending the calm that had settled in after the deflation of 1921 and 1922, became a defining feature of the rest of the decade. Congress tightened immigration policy further with the Immigration Act of 1924, signed May 26, which cut the national-origins quota from 3% of each nationality’s 1910 census population to 2% of its 1890 population, shifting admissions further toward northern and western Europe and effectively excluding most immigration from Asia. Abroad, the U.S.-backed Dawes Plan, adopted that August, reorganized Germany’s war reparations payments and opened the way for American loans into the German economy, helping stabilize European currencies after the hyperinflation that had peaked in 1923. At home, Calvin Coolidge, who had served out the remainder of Warren Harding’s term after his death the previous year, won a full term of his own that November, campaigning on continued prosperity and limited government. First-class postage remained at 2 cents, a price unchanged since mid-1919.

The destination year: 1929

Consumer prices were unchanged in 1929, the CPI’s annual average flat for the second time in six years and a fitting close to a decade that began with wartime inflation and ended in rough price stability. By year’s end the index stood 14.5% below its 1920 peak and roughly 73% above its 1913 starting point, a reminder that even a “stable” decade left prices well above where they had started. The stability in the cost of living masked what was building in financial markets. The National Bureau of Economic Research dates the start of the Great Depression to that August, the month the business cycle peaked, months before most Americans noticed anything was wrong. The break came that October: panic selling hit Wall Street on Black Thursday, October 24, and returned even worse on Black Tuesday, October 29, when the Dow Jones Industrial Average fell about 12% in a single session. Billions of dollars in paper wealth disappeared within days, and the crash marked the start of a downturn that would pull consumer prices into their steepest sustained decline of the 20th century over the next four years. First-class postage was still 2 cents, a price that would hold until 1932.
