Most economic ailments come with their own cure. Recession? Cut rates, boost spending. Inflation? Raise rates, cool demand. The textbook assumes these problems arrive separately, like polite guests taking turns. Stagflation is the rude interloper who shows up with both at once, rendering the standard playbook useless.
The term itself—a portmanteau of stagnation and inflation—entered the lexicon in the 1970s, when the global economy served up a real-time demonstration of what happens when prices surge while growth collapses. For a generation of economists raised on the Phillips curve's tidy trade-off between unemployment and inflation, it was heresy made manifest.
The mechanics of misery
Under normal circumstances, inflation and unemployment move in opposite directions. When the economy runs hot, employers compete for workers, wages rise, and prices follow. When it cools, the reverse happens. This relationship, first observed by economist A.W. Phillips in the late 1950s, suggested policymakers could simply choose their preferred point on the curve.
Stagflation breaks this logic. Prices rise not because of excess demand but because of supply shocks—oil embargoes, crop failures, supply chain ruptures. The economy simultaneously weakens because those same shocks raise costs for businesses and consumers, choking off spending and investment. You get the worst of both worlds: the eroded purchasing power of inflation combined with the job losses of recession.
The 1970s delivered this combination with brutal efficiency. Oil prices quadrupled after the 1973 Arab embargo, then doubled again following the 1979 Iranian revolution. American inflation peaked above fifteen percent. Unemployment climbed past nine percent. The misery index—simply the sum of those two figures—became a grim fixture of political discourse.
Why the standard tools fail
Central banks facing ordinary inflation have a straightforward, if painful, remedy: raise interest rates until borrowing becomes expensive enough to slow spending. But when inflation stems from supply constraints rather than overheated demand, this medicine attacks the wrong disease. Higher rates crush an already-weakened economy without addressing the underlying shortage.
Conversely, the standard response to recession—cutting rates and increasing government spending—risks pouring fuel on inflationary fires. Stimulating demand when supply is constrained simply bids up prices further.
This is the stagflation trap. Every conventional policy response makes at least one problem worse. Central bankers must choose which pain to inflict, knowing any choice invites criticism.
The Volcker solution and its costs
The 1970s stagflation eventually broke, but not gently. Federal Reserve Chairman Paul Volcker, appointed in 1979, chose to prioritize inflation even at enormous economic cost. He pushed the federal funds rate above twenty percent, deliberately inducing the worst recession since the Great Depression. Unemployment exceeded ten percent. Factories closed. Farmers faced foreclosure.
It worked. Inflation collapsed from double digits to under four percent within a few years. But the episode left scars—on communities devastated by the recession, and on policymakers who learned that escaping stagflation requires accepting severe short-term damage to restore long-term stability.
Our take
Stagflation's rarity makes it easy to dismiss as a historical curiosity, a disco-era relic alongside leisure suits and gas lines. This is precisely the wrong lesson. The 1970s demonstrated that supply shocks can arrive suddenly and that the policy toolkit shrinks dramatically when they do. Every central banker today operates in Volcker's shadow, knowing that if stagflation returns, there are no good options—only choices between different varieties of pain. The word itself has become a kind of incantation, invoked whenever inflation rises and growth falters, a reminder that economics occasionally delivers problems without solutions.
