Most economic ailments come with their own cure built in. Recessions, however painful, eventually burn themselves out as prices fall and bargain-hunters return. Inflation, however corrosive, can be tamed by raising interest rates until spending cools. But stagflation—the unholy marriage of stagnant growth, high unemployment, and rising prices—offers no such mercy. It is the condition where the standard remedies for one problem make the other worse, leaving policymakers trapped in a hall of mirrors.
The term itself, a portmanteau of "stagnation" and "inflation," entered the economic lexicon in the 1970s, though the British politician Iain Macleod had coined it a few years earlier to describe the United Kingdom's troubles. What made stagflation so intellectually destabilizing was that it shouldn't have existed at all, at least according to the prevailing Keynesian orthodoxy. The Phillips Curve, that elegant inverse relationship between unemployment and inflation, suggested you could have one or the other—never both simultaneously.
Why the textbooks failed
The 1970s proved the textbooks wrong in spectacular fashion. Oil shocks delivered by OPEC sent energy prices skyward, but unlike demand-driven inflation, this was a supply shock that raised costs while simultaneously crushing economic activity. Businesses faced higher input prices and weaker demand. Workers saw their purchasing power erode even as layoffs mounted. The Federal Reserve, led first by Arthur Burns and then by G. William Miller, attempted to thread an impossible needle, easing policy to fight unemployment only to watch inflation accelerate further.
The mechanism is deceptively simple once you abandon the assumption that all inflation is demand-driven. When costs rise because of external shocks—energy, food, supply chain disruptions—businesses must either absorb the hit to margins or pass it along to consumers. If they absorb it, profits fall, investment stalls, and workers get laid off. If they pass it along, real wages decline, consumer spending weakens, and workers still get laid off. Either path leads to the same grim destination: an economy that is simultaneously too hot on prices and too cold on growth.
The Volcker solution and its costs
Paul Volcker's appointment as Federal Reserve Chairman in 1979 marked the beginning of the end for the great stagflation, but the cure was nearly as brutal as the disease. By raising the federal funds rate to double-digit levels, Volcker deliberately induced a severe recession to break the inflationary psychology that had become embedded in wage negotiations and price-setting behavior. Unemployment peaked above ten percent. Entire industries, particularly housing and manufacturing, were devastated. But inflation, which had reached double digits, was finally crushed.
The Volcker precedent established a template that central bankers have followed ever since: when in doubt, prioritize price stability, even at enormous short-term cost. The logic is that inflation expectations, once unanchored, become self-fulfilling prophecies that are far more expensive to reverse than to prevent. Better to endure one sharp recession than a decade of grinding uncertainty.
The modern specter
Stagflation has remained largely dormant in developed economies since the early 1980s, but its ghost haunts every policy discussion about supply shocks. When energy prices spike, when supply chains seize up, when geopolitical disruptions threaten commodity flows, the question inevitably surfaces: could it happen again? The honest answer is that the conditions for stagflation never truly disappear. They merely await the right combination of shocks and policy errors to reassemble.
What makes stagflation so feared is not just its economic toll but its political toxicity. Voters understand unemployment. They understand inflation. What they cannot forgive is a government that appears helpless against both simultaneously. The 1970s destroyed political careers and reshuffled ideological alignments in ways that still echo through economic debates.
Our take
Stagflation is less a disease than a diagnosis of policy failure—the moment when authorities discover that the tools they trusted have stopped working. Its rarity in recent decades owes less to superior wisdom than to favorable circumstances: globalization suppressing goods prices, technology boosting productivity, and central banks enjoying credibility their predecessors had to earn the hard way. That credibility is not a permanent endowment. It must be defended in each generation, usually at considerable cost. The monster sleeps, but it has not been slain.
