Oil Shocks, Double-Digit Inflation, and the End of Bretton Woods
The 1970s delivered the most severe peacetime inflation in US history. Two oil shocks (1973 and 1979) sent energy prices soaring and triggered double-digit inflation. By 1979, CPI inflation reached 13.3%. The purchasing power of a 1970 dollar had fallen by nearly 50% by 1980. Workers demanded — and received — dramatic wage increases, but wages consistently lagged prices. The Federal Reserve's decision to raise interest rates to 20% under Chairman Volcker in 1980 finally broke the inflation cycle, but at the cost of the worst recession since the Great Depression.
Between 1973 and 1975, the price of gasoline in the US tripled from 38 cents to over $1 per gallon. Adjusted for inflation, this remains one of the largest real-terms energy price shocks in history.

For years before 1913 (USA) or equivalent periods for other countries, the calculation uses reconstructed price indices from academic sources including MeasuringWorth.com and the Bank of England's Millennium Dataset. Pre-industrial calculations carry a wider margin of uncertainty.
Why does purchasing power matter more than just inflation percentage?+
A simple inflation percentage tells you how prices changed, but purchasing power shows you what money could actually buy in human terms. ¥10000 in 1979 bought a specific number of loaves of bread, weeks of rent, or months of wages — context that makes the number real and tangible, not just an abstract percentage.
