What is Stagflation?
Stagflation is the name economists give to a specific kind of economic crisis. It combines three things that normally do not happen together: high inflation, high unemployment, and stagnant or shrinking economic growth. Most recessions look different. In a normal recession, demand falls and people lose jobs. Prices either fall or rise more slowly. The Federal Reserve responds by cutting interest rates to stimulate the economy. The toolkit works because the problem is too little demand.
Stagflation breaks that toolkit. Prices keep rising even as people lose jobs. Cutting rates makes inflation worse. Raising rates makes unemployment worse. There is no clean policy answer. The country has to choose which problem to attack first and accept the cost on the other side. This is why economists treat stagflation as worse than a normal recession. It lasts longer and it is harder to escape. It corrodes confidence in institutions and currencies in ways that ordinary downturns do not.
Why Economists Thought Stagflation Was Impossible
For most of the postwar period, economists believed inflation and unemployment moved in opposite directions. The relationship was named after the New Zealand economist A.W. Phillips, who in 1958 published a study showing an inverse relationship between wage growth and unemployment in British data going back nearly a century.
The Phillips curve, as it became known, gave policymakers a simple choice. Higher inflation came with lower unemployment. Lower inflation came with higher unemployment. A government could pick a point on the curve and aim its policy there. The trade-off was uncomfortable but predictable. This framework dominated economic thinking through the 1960s. The logic seemed intuitive. When demand for workers is high, employers raise wages. Higher wages flow into prices. Inflation rises. When demand for workers falls, wages and prices grow more slowly.
Stagflation was supposed to be impossible under this model. High inflation and high unemployment could not coexist because they came from opposite causes.The 1970s showed the model was incomplete. Inflation and unemployment rose together for nearly a decade. The Phillips curve appeared to break.
Economists eventually understood why. The original curve described what happens when demand changes. It said nothing about what happens when supply is disrupted. An oil shock raises prices and reduces output at the same time. The trade-off vanishes. The two problems compound rather than cancel. This is the key to understanding stagflation. It is not a demand problem but a supply problem dressed up as one.
What Today’s Data Shows
The starting point for any honest analysis is to look at where the economy actually is, not where it was a year ago.
US consumer price inflation in March 2026 reached 3.3 percent, up sharply from 2.4 percent in February. That is the fastest annual pace in nearly two years. The monthly increase of 0.9 percent was the largest since June 2022. Gasoline prices rose 21.2 percent in a single month, the largest monthly jump since 1967.
Core inflation, which excludes food and energy, rose more modestly, from 2.5 percent in February to 2.6 percent in March. The pass-through from energy to other categories takes three to six months to fully appear in the data. The food, transportation, and broader goods readings in April and May reports will reveal how far the shock has traveled. Unemployment in February 2026 was 4.4 percent. That is higher than during 2022 and 2023, when it averaged around 3.6 percent, but still low by historical standards. The post-1948 average is roughly 5.7 percent.
Real GDP continues to grow as of the most recent reading, but forecasts have been cut. The Asian Development Bank reduced its 2026 growth forecast for the Asia-Pacific region from 5.1 percent to 4.7 percent. Goldman Sachs warned that if the Strait of Hormuz remains closed for another month, Brent crude averages above $100 per barrel throughout 2026 and could hit $115 to $120 per barrel in the third and fourth quarters.
The misery index which is the simple sum of inflation and unemployment currently stands at around 7.7. In 1980 it peaked above 21. In 1975 it exceeded 17. Today’s figure does not yet resemble the 1970s crisis. The trajectory matters more than the level.
Federal Reserve Chair Jerome Powell, asked directly in the April 2026 FOMC press conference whether the US was entering stagflation, said: “I would reserve the term stagflation for a much more serious set of circumstances. That is not the situation we’re in.”
That is the official position from the institution most responsible for managing the situation. It is also the right starting point for serious analysis. Today’s data is not stagflation. The honest question is whether the trajectory of the next six to twelve months turns it into something that resembles it.
The Four Preconditions
Looking back at the 1970s, four ingredients combined to produce stagflation. Looking at each one in turn, in the context of May 2026, shows where the risk actually sits.
1. A Major Supply Shock: Active
This is no longer a hypothetical. On February 28, 2026, US and Israeli forces launched coordinated strikes on Iran. On March 4, Iran closed the Strait of Hormuz, the waterway through which roughly 20 percent of global oil consumption and 20 percent of global liquefied natural gas trade passes. The closure was briefly lifted in mid-April and reinstated within twenty-four hours. As of early May, the strait remains effectively shut to commercial traffic.
The International Energy Agency has called this the largest supply disruption in the history of the global oil market. A Dallas Fed working paper estimated the disruption at between two and three times the size of the 1973 and 1979 oil shocks combined. Brent crude rose from approximately $70 per barrel before the conflict to a peak above $120 in March, settling in the $107 to $111 range through April and early May. Oil prices have risen roughly 60 percent since the war began.
The economic transmission has already started. US gasoline prices rose 21.2 percent in March, the largest monthly increase since 1967. Fertilizer prices have surged 30 to 40 percent because the Persian Gulf carries roughly 30 percent of internationally traded fertilizers. Airlines, parcel carriers, and e-commerce platforms have begun adding fuel surcharges. The Asian Development Bank cut regional 2026 growth forecasts by 0.4 percentage points within weeks of the closure.
This precondition is fully present in a way it has not been since 1979. That is the single most important fact for the rest of the analysis.
2. Loose Monetary Policy Beforehand: Mostly Absent
The Federal Reserve under Arthur Burns kept interest rates lower than inflation through much of the early 1970s. Real rates were negative for years. The economy was running hot when the oil shock arrived, with no buffer to absorb the disturbance.
Today’s situation is different. The Fed raised rates aggressively from 2022 to 2024 and has held the federal funds rate in the 3.50 to 3.75 percent range since. Real rates are positive. Markets had been pricing in two rate cuts before the end of 2026. After the March CPI report, that expectation collapsed to one cut, and even that has become uncertain.
This precondition is mostly absent for now. The risk is what happens if the shock persists. A Fed facing a Volcker-style choice between fighting inflation by raising rates further or preventing recession by cutting rates is a Fed under pressure. Powell has signaled he would prioritize inflation control. Whether the next Chair, who takes office in May 2026, takes the same view is not yet known.
3. Wage-Price Spiral Dynamics: Mostly Absent
In the 1970s, strong unions, indexed wage contracts, and ingrained inflation expectations meant rising prices automatically triggered rising wages, which fed back into rising prices. The spiral was self-sustaining.
Today the labor market is less unionized. Most contracts are not formally indexed to inflation. Long-run inflation expectations, as measured by the Federal Reserve Bank of New York’s Survey of Consumer Expectations and the 5-year/5-year forward breakeven rate, have remained close to the 2 percent target through the early stages of the current shock. The shorter 5-year breakeven rate had drifted to 2.67 percent, reflecting expectations of higher near-term inflation from the energy shock, but not a sustained loss of credibility at the longer horizon.
This precondition is mostly absent. It is the strongest argument against a 1970s repeat. The risk is that sustained energy price increases over six or more months begin to shift expectations. The Dallas Fed paper estimated that even in the worst-case duration scenario, 5- to 10-year household inflation expectations would move only modestly. That is reassuring but not definitive as expectations can shift faster than models predict.
4. Loss of Central Bank Credibility: Currently Intact
By the late 1970s, markets and consumers stopped believing the Federal Reserve would defeat inflation. The loss of credibility was itself a cause of further inflation, because workers demanded higher wages preemptively and businesses raised prices preemptively. Volcker’s brutal rate hikes were necessary precisely to rebuild credibility that had been spent.
Today the Fed retains credibility. Markets continue to price in the Fed meeting its 2 percent target over the medium term. Powell’s public statements have emphasized that the Fed will look through energy price volatility but will respond if it begins to feed into core inflation persistently.
This precondition is currently intact. It is also the most fragile of the four. Credibility is built over decades and lost in months. The next two FOMC meetings, and how the Fed handles April and May CPI reports, will matter more for this variable than any speech or projection.
Three Structural Forces That Amplify the Risk
Even with two of four preconditions still mostly absent, the structural environment of 2026 makes a stagflationary scenario more plausible than it was a decade ago. Three forces explain why.
The first is deglobalization. For thirty years after the fall of the Berlin Wall, expanding global trade put downward pressure on the price of goods. China’s integration into the world economy added hundreds of millions of low-wage workers to global supply. That era is ending. Tariffs, supply chain reorganization, and political pressure to source domestically all add cost without adding productivity. Persistent upward pressure on goods prices is a structural feature of the next decade.
The second is demographics. The baby-boomer generation is retiring across developed economies. Labor force participation rates are declining. Fewer workers chasing similar amounts of work pushes wages up regardless of monetary policy.
The third is the energy transition. Building renewable energy, electric vehicle infrastructure, and grid capacity requires enormous amounts of metals, minerals, and capital investment. Most of those costs hit before the productivity benefits materialize. The transition is investment-intensive in its early decades, which means structural pressure on commodity prices and capital costs.
None of these forces individually causes stagflation. Together, they reduce the spare capacity the economy has to absorb a supply shock. The 2026 oil disruption is landing on an economy that is structurally less flexible than the one that absorbed lower-magnitude shocks in 2011 or 2014.
What Investors Should Watch
Today’s framework for thinking about stagflation risk is not “is it happening” but “what determines whether the trajectory turns into something that resembles it.” Five indicators matter most.
The duration of the Strait of Hormuz closure. Goldman Sachs estimates that another month of closure pushes Brent above $100 throughout 2026. A three-month closure pushes it to $115 to $120 in Q3 and Q4. The Dallas Fed estimated that depending on duration, 2026 headline inflation could rise by 0.2 to 1.8 percentage points.
The April and May CPI reports. April’s data was released on May 12 and will reveal whether the energy shock is broadening into core inflation or remaining contained to the energy category. Sustained core inflation acceleration is the early warning that the spiral is starting.
Long-run inflation expectations. The 5-year/5-year forward breakeven rate is the cleanest single indicator. If it begins drifting persistently above 2.5 percent, Fed credibility is under stress. The current level remains close to target.
Wage growth relative to productivity. Wages rising faster than productivity is the mechanism through which inflation becomes self-sustaining. Recent data does not yet show this, but labor market tightness combined with rising costs of living can change the dynamic.
The Fed’s reaction function. Powell’s term as Chair ends in May 2026. Whoever succeeds him will set the tone for whether the institution prioritizes inflation control or growth support. That choice is the variable that most directly determines whether 2027 looks like 1975 or 1995.
How This Article Could Be Wrong
The framework above could fail in two main directions.
It could understate the risk if the closure of the Strait of Hormuz extends through the summer and the inflation pass-through into core categories proves stronger than the Dallas Fed’s models predict. A nine-month closure with rising military tensions in the Gulf would test every assumption about contained energy shocks. The 1973 episode lasted six months and produced inflation that stayed elevated for nearly a decade.
It could overstate the risk if a durable ceasefire holds, oil prices retrace toward $80 by autumn, and AI delivers measurable productivity gains over the next two years. In that scenario, the March 2026 CPI spike becomes a one-quarter event, the Fed cuts rates once or twice in late 2026, and 2027 looks unremarkable. This is the path Powell and the Fed are explicitly hoping for.
Both scenarios are plausible. The honest position in May 2026 is that the next two CPI reports and the next sixty days of Middle East diplomacy will tell us which path we are on. Until then, neither extreme view is supported by the data.
Conclusion
Stagflation is the name economists give to a specific kind of crisis that combines high inflation, high unemployment, and stagnant growth. It is rare because it requires several conditions to coexist. It is feared because it breaks the standard policy toolkit.
Today’s data is not stagflation. Inflation at 3.3 percent and unemployment at 4.4 percent produce a misery index well below the 1970s peaks. The Federal Reserve Chair has explicitly rejected the label. Real GDP continues to grow. What is happening is a major supply shock by the IEA’s estimate, the largest in the history of the global oil market landing on an economy whose other defenses against stagflation are partially intact but no longer untested. Three of the four preconditions are at least partially in place. The fourth, central bank credibility, is currently the line holding everything together.
For investors, the discipline is to hold two ideas simultaneously. Today’s economy is not stagflationary. The risk that it becomes so by late 2026 is higher than at any point since the early 1980s. Both statements are true. Acting on either alone produces worse decisions than acting on both together.
The next FOMC meeting, the April and May CPI reports, and developments in the Strait of Hormuz will tell us more than any forecast will. Investors who watch those signals carefully will be better prepared than those who buy either the “everything is fine” or “stagflation is here” narrative without examination.
