Most economic ailments come with a clear prescription. Recession? Cut interest rates and let credit flow. Inflation running hot? Raise rates and cool demand. The logic is intuitive because these conditions typically arrive alone, and the medicine for one does not poison the other. Stagflation is the exception that terrifies policymakers precisely because it presents both diseases simultaneously, and the cure for either makes the other worse.
The term itself—a portmanteau of stagnation and inflation—entered the lexicon during the 1970s, when the post-war economic consensus shattered against the reality of oil shocks and wage-price spirals. Before that decade, many economists believed the Phillips Curve described a stable trade-off: you could buy lower unemployment by tolerating higher inflation, or vice versa. Stagflation revealed this as a dangerous oversimplification.
The mechanics of a trap
Standard inflation emerges when demand outstrips supply—too much money chasing too few goods. The central bank raises borrowing costs, spending slows, and prices stabilize. But stagflation typically begins with a supply shock: energy prices spike, supply chains fracture, or productivity collapses. Costs rise not because consumers are flush but because production itself has become more expensive. Businesses pass these costs forward while simultaneously cutting output and headcount.
Now the central bank faces an impossible choice. Raise rates to fight inflation, and you crush an economy already struggling to grow, throwing more people out of work. Cut rates to stimulate growth, and you pour fuel on the inflationary fire, eroding the purchasing power of wages that are already failing to keep pace. There is no clean exit.
Why the 1970s still haunt policy
The United States endured stagflation for much of that decade, with unemployment and inflation both reaching double digits at various points. The eventual solution—the aggressive rate hikes under Federal Reserve Chair Paul Volcker beginning in 1979—deliberately induced a severe recession to break inflationary expectations. It worked, but at enormous human cost: unemployment peaked above ten percent, manufacturing towns hollowed out, and a generation learned that central banks would sacrifice jobs to restore price stability if forced to choose.
That institutional memory shapes policy to this day. When inflation began accelerating in the early 2020s, central bankers moved faster than many expected, haunted by the fear that waiting too long would allow expectations to become entrenched. The Volcker lesson is clear: the longer you delay, the more brutal the eventual correction.
Our take
Stagflation is rare because it requires a specific confluence of bad luck and bad policy. But its rarity is precisely why it deserves understanding. When central bankers raise rates into economic weakness—a move that strikes many observers as perverse—they are often trying to prevent a scenario where they would eventually have to raise them far more, for far longer, with far worse consequences. The cruelty is the point, in a sense: a smaller pain now to avoid a larger one later. Whether they judge correctly in any given moment is debatable. That they are haunted by the alternative is not.
