Most economic problems come with their own solutions built in. Recession? Cut rates, stimulate demand, watch employment recover. Inflation? Raise rates, cool spending, prices stabilize. The textbooks are full of these tidy cause-and-effect chains. Stagflation is the monster that breaks the machine entirely.
The term itself — a portmanteau of stagnation and inflation — sounds almost playful, like something a journalist coined for a headline. Which is exactly what happened. British politician Iain Macleod used it in a 1965 parliamentary speech, warning of "the worst of both worlds." Within a decade, the worst of both worlds had arrived.
The impossible combination
Classical economics suggested stagflation shouldn't exist. The Phillips Curve, a foundational concept taught to every economics student, posited an inverse relationship between unemployment and inflation. When jobs were plentiful, workers demanded higher wages, pushing prices up. When unemployment rose, wage pressure eased, and inflation fell. You could have one problem or the other, but not both simultaneously.
The 1970s shattered this assumption. The OPEC oil embargo quadrupled petroleum prices almost overnight, sending shockwaves through every economy dependent on cheap energy — which meant essentially all of them. Suddenly, businesses faced soaring input costs. They raised prices to survive. Consumers, squeezed by higher costs for everything from gasoline to groceries, cut back on spending. Companies responded by laying off workers. Unemployment climbed. Prices climbed. Growth collapsed. The impossible had arrived.
Why the standard tools fail
Central bankers facing stagflation confront an agonizing dilemma. Their two primary instruments — interest rate adjustments and money supply management — work by either stimulating or cooling economic activity. But stagflation demands both simultaneously.
Raise rates to fight inflation, and you crush an already stagnant economy, throwing more people out of work. Lower rates to stimulate growth, and you pour fuel on inflationary fires. There is no clean answer, only trade-offs between different varieties of pain.
The Federal Reserve under Arthur Burns tried to thread this needle in the early 1970s, alternating between fighting inflation and supporting growth. The result was neither — just prolonged misery. It took Paul Volcker's brutal rate hikes in the early 1980s, deliberately inducing a severe recession, to finally break the inflationary psychology that had taken hold. Unemployment briefly exceeded ten percent. It worked, but the cure was almost as devastating as the disease.
Supply shocks and structural fragility
Stagflation typically requires a supply shock — some external force that raises production costs independent of demand. Oil embargoes are the classic example, but anything that disrupts the supply side of the economy can trigger the dynamic: trade wars, pandemic-related bottlenecks, agricultural failures, or energy transitions managed poorly.
This is what makes stagflation so difficult to predict and prevent. Demand-driven inflation responds to monetary policy because central banks can influence how much money people have to spend. Supply-driven inflation laughs at interest rates. You cannot drill more oil or grow more wheat by adjusting the federal funds rate.
Economies with high energy dependence, rigid labor markets, or concentrated supply chains are particularly vulnerable. The more an economy relies on imports for essential inputs, the more exposed it becomes to external shocks that monetary policy cannot address.
Our take
Stagflation endures as economics' boogeyman because it reveals the limits of technocratic management. Central bankers are powerful, but they are not omnipotent. When the problem originates outside the financial system — in oil fields, shipping lanes, or geopolitical conflicts — the elegant models break down. The 1970s taught a generation of policymakers humility. Whether that lesson has been adequately transmitted to their successors remains an open question, one that the next supply shock will answer definitively.
