Most economic problems come with a textbook solution. Recession? Cut rates, boost spending. Inflation? Raise rates, cool demand. Stagflation offers no such clarity. It is the macroeconomic equivalent of a patient presenting with both fever and hypothermia — the standard treatments for one condition make the other worse.

The term itself, a portmanteau of stagnation and inflation, emerged in British political discourse during the late 1960s, but the phenomenon seared itself into collective memory during the following decade. What made the 1970s so traumatic was not merely that prices rose or that unemployment climbed, but that both happened simultaneously and persistently, violating what economists had long believed was a stable trade-off between the two.

Why the standard playbook fails

Central banks typically fight inflation by raising interest rates, which slows borrowing, reduces spending, and eventually brings prices down. The cost is usually some increase in unemployment as economic activity cools. In a normal recession, they do the opposite: cut rates to stimulate borrowing and spending, accepting some inflationary pressure as the price of restored growth.

Stagflation traps policymakers between these responses. Raise rates to fight inflation, and you deepen the stagnation, throwing more people out of work. Cut rates to fight unemployment, and you pour fuel on the inflationary fire. Neither lever works without making the other problem worse. This is why former Federal Reserve Chairman Paul Volcker's aggressive rate hikes in the early 1980s were so politically painful — he chose to crush inflation even at the cost of a severe recession, betting that short-term agony would end the stagflationary cycle.

The supply-side trigger

Stagflation typically requires a supply shock — something that simultaneously raises costs and reduces productive capacity. The oil embargo of 1973 and the subsequent price spikes fit this pattern precisely. When energy costs quadruple, everything that depends on energy becomes more expensive, pushing up prices. But those same higher costs squeeze profit margins, force layoffs, and reduce output. The economy contracts even as prices rise.

This is fundamentally different from demand-driven inflation, where too much money chases too few goods. In demand-pull scenarios, the economy is running hot, unemployment is low, and prices rise because people are spending freely. Supply-shock stagflation hits when the economy is already weakening, making the price increases feel particularly cruel — you lose your job and your purchasing power simultaneously.

The psychological dimension

Perhaps the most insidious aspect of stagflation is what economists call unanchored inflation expectations. When people experience persistent inflation during hard times, they begin to expect prices to keep rising regardless of economic conditions. Workers demand higher wages to keep pace, businesses raise prices to cover those wages, and a self-reinforcing spiral takes hold. Breaking this psychology, as Volcker demonstrated, often requires deliberately inducing enough economic pain that people believe the central bank is serious about price stability.

This is why central bankers speak so obsessively about credibility. Once inflation expectations become unmoored, restoring them is extraordinarily costly. The 1970s taught that lesson in unemployment lines and mortgage defaults.

Our take

Stagflation remains rare precisely because it requires a specific and unfortunate confluence of factors. But its rarity does not diminish its importance. It represents the limiting case of monetary policy, the scenario where the tools that work in normal times become instruments of self-harm. Every time oil prices spike, every time supply chains fracture, every time inflation rises during a slowdown, the spectre returns. Understanding stagflation is not academic exercise — it is preparation for the moment when the easy answers run out.
