Stagflation is the combination of high inflation, stalled economic growth, and rising unemployment happening at the same time, a mix that mainstream economics spent the 1960s insisting couldn’t happen. Inflation was supposed to be the price of a hot economy, more jobs and faster growth bought with a bit more inflation, never the two running high together. The 1970s broke that assumption for a decade, and the word invented to describe the wreckage stuck.
Where the word comes from
British Chancellor of the Exchequer Iain Macleod coined “stagflation” in a November 1965 speech to the House of Commons, welding “stagnation” and “inflation” together to describe an economy stuck with both at once. It was still a novelty then. American policymakers in the 1960s were working from the Phillips curve, economist A.W. Phillips’s 1958 finding that unemployment and wage inflation moved in opposite directions across nearly a century of UK data, and which economists turned into a tool for tuning the economy: accept slightly more inflation, buy slightly lower unemployment. Economists Milton Friedman and Edmund Phelps separately warned in 1967 and 1968 that this tradeoff was a short-run illusion, that workers and businesses would eventually build the expected inflation into wages and prices and the “bought” jobs would evaporate. The 1970s tested that warning in real time, and it held.
How prices and output can rise and fall together
The textbook demand-driven story of inflation, too much money chasing too few goods, doesn’t explain stagflation, because demand-driven inflation usually comes with a booming, not stalling, economy. Stagflation instead traces to a supply shock: something makes producing and transporting goods more expensive across the entire economy at once, most classically a spike in oil prices, which raises costs for a manufacturer, a trucking company, and a farmer simultaneously. Businesses facing higher costs raise prices (inflation) while also cutting production and payrolls because the higher costs squeeze profits (stagnation), and both effects hit before wages or efficiency have any chance to adjust. Oil is the classic trigger precisely because it’s the same volatile, economy-wide cost driver that core inflation exists to filter out of the headline number; the difference in a stagflation episode is that the shock is large enough, and lasts long enough, that it drags the whole economy down with it rather than passing through as noise. A wage-price spiral can then entrench the pattern: workers demand raises to keep up with prices, businesses raise prices again to cover the higher wage bill, and the cycle repeats even after the original shock has passed.
America’s stagflation decade
For the full seventeen-year arc from the first signs of overheating in 1965 to Volcker’s disinflation in 1982, see the Great Inflation; the summary below covers just the stagflation years at its core.
The OPEC oil embargo of October 1973 roughly quadrupled crude prices within months, and the U.S. economy absorbed the shock as a textbook case: the CPI rose about 11% in 1974 while the country sank into what was then the worst recession since the Great Depression, unemployment climbing to nearly 9% by May 1975. Inflation and joblessness, the two numbers that were never supposed to move together, both went up. The pattern repeated after the 1979 Iranian Revolution cut world oil supply again: inflation reached 11.35% in 1979 and peaked at 13.5% in 1980, even as unemployment stayed elevated through a brief recession that same year. Economist Arthur Okun’s misery index, just the unemployment rate plus the inflation rate added together, topped 20 in 1980, a level the U.S. had never reached before and hasn’t touched since.
How the cure differed from the disease
By 1981, the picture had started to shift. Inflation was falling, 10.3% for the year versus 13.5% the year before, but unemployment was still climbing, eventually reaching 10.8% in the deep 1981-82 recession that Federal Reserve chairman Paul Volcker engineered on purpose, pushing the federal funds rate above 19% to strangle inflation expectations out of the economy. That stretch is often lumped in with “the stagflation years,” but it’s really the opposite condition: a recession deliberately traded for lower inflation, not the two rising together. True stagflation had already peaked; what came next was the bill for ending it. It worked, inflation fell to 3.2% by 1983, but at the cost of the worst unemployment since the 1930s.
Why stagflation is rare, and why 2022 wasn’t one
Genuine stagflation needs both halves at once, and that combination has been unusual in U.S. history outside the 1970s. The 2021-2023 inflation surge is a useful contrast: the CPI rose roughly 8% at its 2022 peak, close to the 1970s pace, but unemployment stayed near 50-year lows throughout, since the shock this time was pandemic-era supply chains and stimulus-fueled demand rather than a 1970s-style cost shock landing on an already-weak economy. High inflation with a strong labor market is uncomfortable, but it isn’t stagflation. The term belongs specifically to the rarer, more dangerous case where a central bank’s usual response, raising rates to cool demand, offers no clean fix, because the problem isn’t excess demand to begin with, and cooling the economy further only adds unemployment on top of prices that are already rising for reasons rate hikes can’t touch.
