Most economic ailments come with a cure, however painful. Recession? Cut rates and spend. Inflation? Raise rates and wait. Stagflation offers no such comfort. It presents policymakers with a paradox: the medicine for one symptom worsens the other, leaving governments to choose which pain their citizens will bear.
The term itself—a portmanteau of stagnation and inflation—was coined in the British Parliament in the 1960s, but the condition achieved infamy in the following decade when oil shocks, wage-price spirals, and misguided monetary policy combined to produce a sustained period of economic misery across the industrialized world. Unemployment climbed while prices rose relentlessly. The Phillips Curve, which had suggested a stable trade-off between the two, appeared to break down entirely.
The mechanism of misery
Stagflation typically begins with a supply shock—an external disruption that raises production costs across the economy. When energy prices spike or critical inputs become scarce, businesses face a choice: absorb the costs and watch margins collapse, or pass them to consumers. Most choose the latter. Prices rise not because demand is strong, but because supply is constrained.
This is where the cruelty begins. Central banks confronting ordinary inflation can raise interest rates, cooling demand until prices stabilize. But in stagflation, demand is already weak. Households are cutting back because their purchasing power is eroding. Businesses are laying off workers because margins are squeezed. Raising rates further deepens the downturn without necessarily taming inflation, because the price pressure originates in supply, not demand.
Conversely, stimulating the economy with lower rates or fiscal spending risks pouring fuel on the inflationary fire. The policy toolkit, so effective in normal times, becomes a collection of bad options.
Why the 1970s still haunt
The scars of that decade run deep in central banking culture. The Federal Reserve, under Arthur Burns, initially tried to accommodate the oil shocks, keeping policy loose to protect employment. Inflation expectations became unmoored. Workers demanded higher wages to keep pace with prices; businesses raised prices to cover higher wages. The spiral fed itself.
It took Paul Volcker's brutal interest rate increases in the early 1980s—pushing the federal funds rate above eighteen percent—to finally break the cycle. The cost was the deepest recession since the Great Depression. Unemployment reached nearly eleven percent. But inflation fell, and stayed down for a generation.
The lesson central bankers absorbed was severe: credibility is everything. Once the public believes inflation will persist, it becomes self-fulfilling. Better to act aggressively early than to let expectations drift.
Our take
Stagflation remains the scenario that keeps monetary policymakers awake at night precisely because it exposes the limits of their power. In a world of increasingly fragile supply chains and geopolitical volatility, the conditions for supply shocks have not disappeared. The best defense is not a clever policy response—it is avoiding the trap altogether, which means maintaining credibility before the storm arrives. Central bankers who appear hesitant or politically captured invite the very expectations that make stagflation possible. The 1970s were not ancient history; they were a warning.
