One month into the war in Iran, the global economy is no longer dealing with a temporary geopolitical shock. It is dealing with a widening economic crisis that is spreading through energy markets, food systems, financial conditions, industrial supply chains, and household budgets across the world. What initially looked like a severe but potentially contained conflict has evolved into a deeper and more durable disruption, one that is now raising increasingly serious concerns about how quickly the world economy can recover.
The most immediate damage has come through energy. Oil prices have surged, natural gas infrastructure has been hit, and governments across multiple regions have begun rationing fuel or stepping in with subsidies to soften the blow for vulnerable households. But the damage does not stop there. Fertilizer prices are rising, threatening future food inflation. Helium supply has been disrupted, creating pressure on advanced sectors such as semiconductors, rockets, and medical imaging. Airlines are facing higher costs and operational disruption. Financial markets have become more fragile. And the risk of stagflation — that toxic mix of high inflation and weak growth — has moved much closer to the center of the conversation.
What makes this situation especially troubling is that the economic burden is no longer being driven only by fear or speculation. Infrastructure is being damaged. Trade routes are being disrupted. Supplies are being constrained. As Christopher Knittel, an energy economist at MIT, noted, if the war had ended earlier, the long-term consequences may have been relatively limited. But once energy infrastructure is actually being destroyed, the fallout becomes much more persistent. This is what changes a market shock into an economic shock.
That is why recovery worries are intensifying. The global economy has already survived a pandemic, the war in Ukraine, inflation spikes, and aggressive interest-rate tightening. For a while, there was hope that it might absorb another conflict as well. But as the war in Iran drags on, that optimism is fading. The world is now facing a crisis that touches everything from the cost of filling a gas tank to the price of food, the availability of industrial inputs, and the resilience of consumer demand.
The oil shock has become the core of the crisis
The center of the economic damage remains oil. Iran’s effective closure of the Strait of Hormuz turned an already dangerous conflict into a global supply emergency almost immediately. The strait is one of the most important energy chokepoints in the world, handling roughly one-fifth of global oil supply as well as major flows of liquefied natural gas. When it stopped functioning as a reliable route, the consequences hit markets fast.
Gulf exporters such as Kuwait and Iraq reduced output because they had fewer viable ways to move their oil. The resulting loss of around 20 million barrels a day produced what the International Energy Agency described as the largest supply disruption in the history of the global oil market. That is a staggering assessment, and it explains why oil prices have remained elevated even amid hopes of diplomacy.
Brent crude rose 3.4% on Friday to settle at $105.32 per barrel, up sharply from around $70 just before the war began. U.S. benchmark crude climbed 5.5% to $99.64. Those are not just trader headlines. They feed directly into the everyday economy. Higher crude means more expensive gasoline, diesel, shipping, aviation fuel, plastics, and industrial production. That cost then filters through to consumers and businesses everywhere.
Historically, oil shocks of this scale have often been followed by recessions. That does not make a downturn inevitable, but it raises the stakes considerably. Energy remains one of the fastest ways for a war to spread economic pain far beyond the region where it began. Every country that imports oil, directly or indirectly, ends up feeling the consequences.
A new wave of stagflation anxiety is building
One of the most alarming features of the current crisis is the return of stagflation fears. Stagflation refers to a situation in which inflation stays high while economic growth weakens. It is one of the most difficult environments for policymakers to manage because the usual tools do not work cleanly. Central banks cannot easily cut interest rates to support growth if inflation is still being pushed up by energy and supply shocks. At the same time, keeping rates high can worsen the slowdown.
That is why economists are drawing uncomfortable parallels with the 1970s. Back then, oil shocks triggered a long and painful period of weak growth, high inflation, and rising economic anxiety. The present situation is not identical, but the mechanism feels familiar. Carmen Reinhart of Harvard has warned that the war is raising the risk of higher inflation and lower growth at the same time. That is precisely the condition policymakers most want to avoid.
Former IMF chief economist Gita Gopinath has also underscored how sensitive global growth is to energy prices. Before the war, the global economy was expected to grow by around 3.3% this year. If oil prices average $85 a barrel in 2026, she suggested global growth could be 0.3 to 0.4 percentage points lower. Given that oil is already well above that threshold, the market now has to consider the possibility that the drag on global output could be more severe if disruption continues.
That is why the war in Iran is no longer just a geopolitical issue. It has become a macroeconomic problem. The longer it lasts, the greater the chance that rising prices and weakening demand begin to reinforce one another in a more dangerous way.
Fertilizer shortages could make food inflation the next phase of the crisis
Oil gets most of the attention, but one of the most consequential spillovers from the war may be happening in fertilizer markets. The Persian Gulf is a major source of exports for two key fertilizers: urea and ammonia. Producers in the region benefit from low-cost natural gas, which is essential for making nitrogen fertilizers. Up to 40% of global nitrogen fertilizer exports pass through the Strait of Hormuz.
Now that the route is blocked or heavily disrupted, fertilizer prices have jumped. Urea prices are up 50% since the war began, while ammonia prices are up 20%. This may seem like a specialized commodity story, but it has enormous implications for food.
Higher fertilizer prices generally lead to one of two outcomes. Farmers either pay more and accept lower margins, or they use less fertilizer and accept lower yields. Both paths eventually point toward higher food prices. The pain will not be distributed equally. Families in poorer countries, which already spend a larger share of their income on food, will feel the squeeze most sharply.
Countries like Brazil are particularly vulnerable because they depend heavily on imported fertilizer. Egypt, while itself a major fertilizer producer, relies on natural gas to produce it and becomes more exposed when gas supply tightens. The risk is not just that food becomes more expensive. It is that food becomes less abundant, especially in regions where agriculture is already operating under pressure from climate, import dependency, and weak currencies.
In other words, the war’s economic effects are moving beyond fuel and into the most basic item of all: food security.
Helium shortages show how far the disruption is spreading
Another important but less publicized consequence of the war is the disruption of helium supply. Qatar produces around a third of the world’s helium, and much of it comes from the Ras Laffan facility that was struck during the conflict. Helium is a byproduct of natural gas production, and while it is often overlooked in public debate, it is critical for several high-value industries.
Semiconductor manufacturing depends on helium. So do rockets and advanced medical imaging systems. In a global economy that is increasingly counting on chips, AI infrastructure, and high-tech investment to sustain growth, disruptions to helium are not minor. They are another example of how this war is affecting sectors that extend far beyond oil.
That matters because many investors had been counting on technology and AI-related industries to keep supporting broader economic optimism. If those sectors face added supply stress on top of already elevated costs, the fallout could become more serious than headline oil charts alone suggest.
The war is therefore not simply an energy crisis. It is a broader input crisis, with implications for industrial production, healthcare technology, and the digital economy.
Developing countries are already being forced into emergency measures
No country is immune if the crisis continues, but poorer countries are especially exposed. As International Energy Agency head Fatih Birol put it, the effects will spread widely if the war continues in its current direction. Lutz Kilian of the Dallas Fed made the same point more bluntly: lower-income countries are likely to face the biggest energy shortages because they will simply be outbid in competition for the remaining oil and natural gas.
That dynamic is already visible in Asia. More than 80% of the oil and LNG that normally passes through the Strait of Hormuz heads toward Asian economies, making the region especially vulnerable.
In the Philippines, government offices are now operating only four days a week, and officials are being told to keep air conditioning no cooler than 75°F. In Thailand, public workers have been told to use stairs instead of elevators to conserve energy. In India, the government is prioritizing household access to liquefied petroleum gas and absorbing much of the price increase to protect poor families. Yet even there, shortages are forcing restaurants to shorten hours, close temporarily, or remove dishes that require more fuel to prepare.
South Korea has also reintroduced fuel price caps and restricted public employees’ car use. These are not ordinary responses to market fluctuation. They are emergency-style interventions that reflect how rapidly a war-centered energy shock can spill into domestic policy and daily behavior.
The United States is somewhat cushioned, but not safe
The United States is in a better position than many countries because it exports oil and benefits from abundant domestic gas supplies. LNG prices remain lower in the U.S. than in other parts of the world because export liquefaction facilities are already operating at full capacity, which means additional gas cannot easily be shipped out. That leaves more supply at home.
But this does not mean the American economy is safe. Higher gasoline prices are still hitting households, and consumer psychology in the U.S. remains especially sensitive to pump prices. According to AAA, average gasoline prices have risen to nearly $4 a gallon from $2.98 just a month ago. That kind of jump is immediately visible to drivers and politically potent.
It is also hitting an economy that was already showing signs of weakness. U.S. growth slowed to a 0.7% annual pace from October through December, down sharply from 4.4% in the previous quarter. Employers unexpectedly cut 92,000 jobs in February and added only 9,700 jobs a month on average in 2025, the weakest non-recession pace of hiring since 2002. Gregory Daco of EY-Parthenon has now raised the probability of a U.S. recession over the next year to 40%, compared with a normal risk closer to 15%.
So while the United States is more insulated than many import-dependent economies, it is still vulnerable. Higher energy costs arrive at a time when the labor market and growth picture were already becoming less convincing.
Recovery may take far longer than markets initially hoped
Perhaps the most sobering conclusion is that even if hostilities were to ease, recovery would not be immediate. Some damage is already locked in. Qatar’s Ras Laffan LNG facility, which accounts for 20% of world LNG production, lost 17% of its export capacity after the March 18 strike. QatarEnergy has said repairs could take up to five years.
That time horizon is crucial. Repairing damaged LNG infrastructure, refineries, pipelines, and tanker terminals is not quick. Tankers need to be re-provisioned. Marine fuel systems need to be restored. Logistics chains need to be rebuilt. Insurance conditions need to normalize. Even under the best circumstances, these processes move slowly.
This is why hopes for a quick shrug-off are fading. The world economy has been impressively resilient in recent years, surviving the pandemic, the war in Ukraine, high inflation, and aggressive monetary tightening. But resilience is not the same as immunity. The war in Iran is not just another test of nerves. It is now a source of physical damage with long-term economic implications.
Conclusion
As the war in Iran grinds on, its toll on the global economy is becoming broader, deeper, and harder to dismiss. Oil prices are higher. Inflation risks are intensifying. Fertilizer and helium supplies are under pressure. Poorer countries are rationing energy and rewriting daily routines to cope. Financial markets are uneasy. And even the United States, with all its relative advantages, is feeling the strain through higher fuel prices and a more fragile economic backdrop.
The most troubling part is that this crisis is no longer about temporary shock alone. It is about damaged infrastructure, restricted trade routes, and economic stress that could last well beyond the battlefield phase of the conflict. That is why recovery fears are growing. The longer the war continues, the more it stops looking like a short disruption and starts looking like a structural drag on the global economy.
At this stage, as Moody’s Mark Zandi and his colleagues put it, there is no economic upside to the conflict with Iran. The real questions now are how long the war will continue and how much more economic damage it will inflict before it ends.
