The economy can slow because energy is scarce, or because people believe it will be.
At a moment when the world's economies were already carrying the weight of elevated interest rates and stubborn inflation, a new set of forecasts has arrived to remind us that energy — the lifeblood of modern civilization — remains a fragile and politically entangled resource. Two scenarios now define the horizon: one in which disruptions from escalating tensions around Iran prove brief but still costly, and one in which a prolonged conflict delivers the rare and punishing combination of stagnant growth and rising prices. In either case, economists agree that the growth trajectory of 2026 will not be what it was before, and that the margin for error, for governments and central banks alike, has quietly narrowed.
- Two credible recession paths are now on the table — neither optimistic — and the difference between them hinges on how long the Iran conflict continues to threaten global energy flows.
- The OECD has raised the specter of stagflation: a toxic pairing of weakening growth and rising inflation that strips policymakers of their most reliable tools, forcing central banks to choose between two forms of pain.
- The disruption lands on economies already strained — high interest rates, elevated wages, and large fiscal deficits mean there is far less cushion to absorb a new shock than there was even five years ago.
- Beyond the hard data of oil prices and supply chains, economists are watching something more elusive: whether businesses and consumers begin to act as if the crisis is permanent, triggering slowdowns through fear alone.
- The path forward depends on a combination of geopolitical luck and deliberate policy — how quickly the conflict stabilizes, how aggressively central banks respond, and whether governments choose to cushion the blow or let it land unmediated.
The global economy is entering a period of genuine uncertainty, and the forecasts arriving this week offer little comfort. Two distinct scenarios are circulating among economists and policy institutions — one worse than the other, but neither encouraging for growth or stability in the months ahead.
In the more optimistic case, energy disruptions tied to escalating tensions in Iran remain brief. Even so, global growth will slow noticeably. Inflation, which had been cooling across many developed economies, will prove stickier than hoped, and central banks will face a familiar dilemma: tighten policy and risk deepening the slowdown, or hold steady and risk letting price pressures re-entrench.
The second scenario is grimmer. A protracted conflict would constrain energy supplies for months, not weeks, producing what the OECD calls a severe drag on global growth alongside rising inflation — stagflation, the toxic combination that leaves policymakers with few good options. Supply chains would face new shocks, manufacturing would contract, and consumer confidence would erode alongside purchasing power.
What makes these forecasts particularly sobering is that they represent a genuine fork in the road. But both paths share a common thread: something has shifted. Energy security, long assumed to be a solved problem, has re-emerged as a fundamental constraint on economic life.
The timing compounds the difficulty. Many economies are still adjusting to the higher interest rates of recent years. Wage growth remains elevated, fiscal deficits are substantial, and resilience is already being tested. A shock that might have been absorbed more easily in an earlier era now arrives with less cushion available.
Economists are watching oil prices, but they are also watching something harder to quantify: confidence. If businesses and consumers believe the disruption will be brief, they may weather it. If they begin to fear a prolonged crisis, investment slows, hiring pauses, and the economy contracts not only because energy is scarce, but because people believe it will be — and act accordingly. The forecasts are in. Now comes the harder part: navigating them.
The global economy is entering a period of genuine uncertainty, and the forecasts arriving this week offer little comfort. Two distinct scenarios are now circulating among economists and policy institutions, each painting a picture of economic strain—one worse than the other, but neither particularly encouraging for growth or stability in the months ahead.
The first scenario assumes that energy disruptions stemming from escalating tensions in Iran remain contained and relatively brief. Even in this more optimistic case, the world economy will slow noticeably this year. Oil prices may peak and begin to recede, but the damage to growth momentum will already be done. Inflation, which had been cooling in many developed economies, will prove stickier than hoped. Central banks will face a difficult calculus: tighten policy and risk deepening the slowdown, or hold steady and risk letting price pressures re-entrench themselves in wage-setting and expectations.
The second scenario is grimmer. If the Iran conflict stretches into a prolonged disruption—if energy supplies remain constrained for months rather than weeks—the economic consequences would be severe. The OECD, in its latest assessment, warns that a protracted conflict would drag down global growth substantially while simultaneously pushing inflation higher. This is the worst combination for policymakers: stagflation, the toxic blend of weak growth and rising prices that leaves few good policy options. Supply chains already stressed by years of disruption would face new shocks. Manufacturing would contract. Consumer spending would weaken as purchasing power erodes and confidence falters.
What makes these forecasts particularly sobering is that they represent a genuine fork in the road. The outcome is not predetermined. It depends on how quickly the geopolitical situation stabilizes, on how much oil actually flows out of the region, on how markets respond to uncertainty. But what both scenarios share is a common thread: the global economy will not simply bounce back to the growth trajectory it was on before. Something has shifted. Energy security, which many assumed was a solved problem, has re-emerged as a fundamental constraint on economic activity.
The timing compounds the difficulty. Many economies are still adjusting to higher interest rates implemented over the past two years to combat inflation. Labor markets remain tight in some regions, wage growth is still elevated, and fiscal deficits in major economies remain substantial. There is less room to maneuver, less cushion, than there was before. A shock that might have been absorbed with relative ease five years ago now arrives at a moment when resilience is already being tested.
Economists are watching oil prices closely, but they are also watching something harder to quantify: confidence. If businesses and consumers believe the disruption will be brief and contained, they may weather it. If they begin to fear a prolonged crisis, behavior changes. Investment gets delayed. Hiring slows. Spending becomes more cautious. The economy can slow not just because energy is scarce, but because people believe it will be scarce, and act accordingly.
What happens next depends partly on forces beyond any single government's control—the trajectory of the conflict, the resilience of energy markets, the response of OPEC producers. But it also depends on policy choices: how aggressively central banks respond, whether governments provide targeted support or allow the shock to ripple through unmediated, whether international coordination can help stabilize expectations. The forecasts are in. The paths are laid out. Now comes the harder part: navigating them.

OECD warns that a protracted conflict would drag down global growth substantially while simultaneously pushing inflation higher— OECD economic assessment
A Conversa do Hearth Outra perspectiva sobre a história
So we're looking at two different futures here. What separates them?
Timing, mostly. How long the energy disruption lasts. If it's weeks, the economy slows but absorbs it. If it's months, you get something much uglier—growth stalls while prices keep rising.
And the OECD thinks the longer scenario is plausible?
They're not saying it's likely, but they're saying it's real enough to warn about. That's the point of laying out two scenarios—one is bad, one is worse, and you need to prepare for either.
What makes this moment different from other oil shocks?
Economies are already fragile. Interest rates are high. Inflation hasn't fully cooled. There's less room to absorb a shock without something breaking.
So even the optimistic case isn't actually optimistic?
Right. Even if oil prices peak and start falling, growth still decelerates this year. The damage is already in motion.
What are people actually watching for as a signal?
Oil flows. How much energy actually leaves the region, how quickly markets stabilize, whether confidence holds. But also wages, hiring, business investment—the behavioral stuff. If people think it'll be bad, they act like it will be bad, and that becomes self-fulfilling.
