Stagflation
Stagflation is a rare and economically difficult combination of stagnant economic growth (or recession), high unemployment, and high inflation occurring simultaneously, defying the conventional inverse relationship described by the Phillips Curve and presenting policy makers with an acute dilemma.
The term stagflation is a portmanteau of 'stagnation' and 'inflation,' coined in the 1970s to describe what many economists had considered theoretically impossible: an economy experiencing both rising prices and rising unemployment at the same time. Standard Keynesian demand management assumed that inflation and unemployment moved in opposite directions; fighting one meant tolerating more of the other. Stagflation invalidated that assumption.
The canonical episode of US stagflation occurred in the 1970s, driven by a series of supply-side shocks. The 1973 OPEC oil embargo quadrupled crude oil prices almost overnight, raising production costs across virtually every sector of the economy. Firms faced higher input costs and responded by raising prices (inflation) and cutting output and workers (recession and unemployment). The shock was fundamentally different from the demand-pull or cost-push inflation that policymakers were accustomed to managing.
The policy response to stagflation exposed an inherent tension. Raising interest rates could in theory fight inflation but would further depress an already weak economy and raise unemployment. Cutting rates or increasing government spending to fight the recession would risk stoking inflation further. The Fed attempted various middle-ground approaches under Chairs Arthur Burns and G. William Miller, with limited success. Inflation remained elevated and the economy endured multiple recessions.
The definitive resolution came when Paul Volcker took the Fed chairmanship in 1979 and dramatically tightened monetary policy, driving the federal funds rate above 20%. This induced a severe recession (unemployment peaked above 10%) but succeeded in breaking inflation expectations and ending the stagflationary episode. The cure was painful but effective, and the Volcker disinflation marked a turning point in modern central banking.
Stagflation fears resurfaced in 2022-2023, as energy shocks from the Russia-Ukraine conflict combined with pandemic supply chain disruptions raised prices even as growth concerns mounted. The episode ultimately resolved into high-inflation-with-moderate-growth rather than true stagnation, but it reminded investors that stagflationary dynamics can re-emerge during supply shocks and deserve a place in portfolio risk frameworks. Commodities, TIPS, and energy equities historically perform relatively well in stagflationary environments.
