Most economic problems come with their own solutions. Unemployment too high? Stimulate demand. Inflation running hot? Cool things down with higher rates. The elegance of modern monetary policy rests on this seesaw logic: push one problem down, and you can tolerate the other rising a bit. Stagflation breaks the seesaw.
The term itself—a portmanteau of stagnation and inflation—was coined by a British politician in the 1960s, but it became a household word during the following decade, when the United States experienced something economists had considered nearly impossible: prices climbing relentlessly while unemployment soared and growth collapsed. The Phillips Curve, that reassuring inverse relationship between inflation and joblessness, simply stopped working.
How the impossible became real
The 1970s stagflation had multiple fathers. The oil embargo following the 1973 Arab-Israeli war quadrupled petroleum prices almost overnight, injecting a supply shock into an economy already running warm from Vietnam War spending and loose monetary policy. But the deeper cause was a loss of anchoring. Workers, expecting prices to keep rising, demanded higher wages. Businesses, expecting costs to keep climbing, raised prices preemptively. Expectations became self-fulfilling.
The Federal Reserve, under Arthur Burns, made things worse by refusing to accept the painful medicine. Every time unemployment ticked up, the Fed eased. Every easing fed inflation. By the time Paul Volcker took the chair in 1979, inflation had reached double digits and the only cure was deliberate recession—interest rates pushed above 20 percent, unemployment allowed to climb past 10 percent, and two brutal years of economic contraction.
Why the playbook fails
Stagflation is uniquely cruel because it closes off the exits. Raise rates to fight inflation, and you deepen the unemployment crisis. Cut rates to stimulate growth, and you pour gasoline on prices. Fiscal stimulus faces the same trap: government spending might create jobs, but it also adds to demand and pushes prices higher. Austerity might cool inflation, but it throws more people out of work.
The only real solutions are slow and politically toxic. Volcker's approach—crushing inflation through sustained monetary tightening regardless of the employment cost—worked, but it required a Fed chairman willing to be the most hated man in America. Supply-side reforms that increase productivity can help, but they take years to materialize. There is no quick fix, which is why policymakers pray they never have to face it.
The conditions that summon it
Stagflation typically requires a supply shock combined with already-loose policy and unanchored expectations. The 1970s had oil embargoes. Future episodes might come from different sources: prolonged supply chain disruptions, energy transitions that raise costs before lowering them, or geopolitical fragmentation that makes global trade more expensive. Climate-related agricultural failures could spike food prices while damaging economic output. The mechanisms vary; the trap is the same.
Our take
Stagflation is the economic equivalent of a two-front war, and history suggests there is no clever maneuver that avoids casualties. The Volcker lesson is uncomfortable but clear: the longer you delay confronting it, the worse the eventual reckoning. Central bankers today speak constantly about keeping inflation expectations anchored precisely because they understand what happens when those expectations slip loose. The 1970s were not ancient history; they were a warning that the fundamental constraints of economics do not bend to wishful thinking.
