US Inflation from 1928 to 2010

What Drove Inflation from 1928 to 2010

Roaring Twenties: After the 1920–21 deflation shock, the US economy roared back. Mass production techniques, especially in the auto industry, drove productivity gains and kept goods prices surprisingly stable even as wages rose. Consumer credit expanded rapidly, fueling purchases of cars, appliances, and homes. Financial speculation ran rampant, and the stock market tripled before the crash of October 1929 exposed the era's fragile foundations.

Great Depression: The stock market crash of 1929 triggered bank panics, credit contraction, and the worst deflation in modern American history. Consumer prices fell nearly 25% between 1929 and 1933 as unemployment exceeded 25% and output collapsed. Roosevelt's New Deal programs stabilized prices and boosted demand, but a premature fiscal tightening in 1937–38 caused a painful recession-within-depression. Full recovery awaited wartime mobilization.

World War II: The US entry into World War II following Pearl Harbor transformed the economy virtually overnight. Defense spending surged to over 40% of GDP, unemployment vanished, and inflationary pressures built rapidly. The government responded with comprehensive wage and price controls, rationing, and war bond drives that suppressed spending. Officially measured inflation was moderate, but pent-up demand and informal price pressures were immense.

Postwar Boom: The end of wartime controls unleashed a burst of inflation in 1946–48 as pent-up consumer demand met supply shortages. After that adjustment, the postwar boom settled into a long era of moderate inflation and strong real growth. The GI Bill, suburban expansion, a baby boom, and rising consumer spending drove prosperity. Inflation averaged around 2% per year through most of the 1950s and early 1960s.

Great Society & Vietnam: President Johnson's Great Society programs and escalating Vietnam War spending drove federal deficits higher without compensating tax increases. The Federal Reserve, under political pressure to keep rates low, accommodated this fiscal expansion. Inflation, which had been below 2% in the early 1960s, climbed steadily past 5% by 1969. Nixon imposed wage and price controls in 1971, temporarily suppressing inflation while setting the stage for a more severe outbreak.

Stagflation: The 1973 Arab oil embargo sent oil prices quadrupling almost overnight, triggering a global recession and double-digit US inflation simultaneously. A second oil price shock in 1979–80 doubled energy costs again. The toxic combination of high inflation and high unemployment — stagflation — exposed the limits of traditional demand management. Paul Volcker's appointment as Federal Reserve chairman in 1979 marked the turning point, as aggressive rate hikes eventually broke the inflationary spiral.

Disinflation: Volcker's medicine worked, but at a steep price: the 1981–82 recession was the deepest since the Depression, with unemployment exceeding 10%. Inflation fell rapidly from above 13% to below 4% by 1983. The subsequent expansion was long and vigorous, supported by falling oil prices, deregulation, and tax cuts. The Federal Reserve established credibility as an inflation fighter, anchoring expectations and keeping prices relatively stable through the rest of the decade.

Moderate Growth: A mild recession in 1990–91 gave way to the longest US economic expansion on record, running through March 2001. Globalization, technology productivity gains, and Federal Reserve credibility kept inflation low and stable. The 2001 dot-com bust and 9/11 attacks caused a brief, shallow recession. The subsequent expansion was driven by housing and consumer credit, with inflation remaining tame as Chinese goods imports suppressed goods prices globally.

Financial Crisis: The collapse of the US housing bubble triggered a global financial crisis of historic proportions. As mortgage-backed securities lost value and interbank lending froze, the Federal Reserve slashed rates to zero and deployed emergency lending facilities. The economy contracted sharply in 2008–09, and deflationary pressures emerged as credit collapsed and unemployment surged toward 10%. Massive fiscal stimulus and quantitative easing gradually stabilized conditions, but recovery was painfully slow.

Understanding the Numbers

Over these 82 years, prices increased more than fourfold — a total inflation rate of +1175.2%. The annualized rate of +3.15% per year was roughly in line with the historical average of roughly 3.3% per year.
