Global Economic Outlook Darkens as Iran War Escalates, Fueling Inflation Fears
Worries about global economic pain are intensifying as the conflict in Iran persists, with U.S. and Israeli military actions significantly darkening the outlook for the world economy. Ongoing strikes and counterstrikes on Persian Gulf refineries, pipelines, gas fields, and tanker terminals threaten to prolong economic distress for months, if not years, according to energy economists.
Infrastructure Destruction Compounds Long-Term Ramifications
"A week ago or certainly two weeks ago, I would have said: If the war stopped that day, the long-term implications would be pretty small," noted Christopher Knittel, an energy economist at the Massachusetts Institute of Technology. "But what we're seeing is infrastructure actually being destroyed, which means the ramifications of this war are going to be long-lived."
Iran's attack on Qatar's Ras Laffan natural gas terminal, which produces 20% of the world's liquefied natural gas, exemplifies this damage. The March 18 strike wiped out 17% of Qatar's LNG export capacity, with repairs expected to take up to five years, as reported by state-owned QatarEnergy.
Oil Shock and Stagflation Risks Emerge
The war triggered an immediate oil shock when Iran responded to U.S. and Israeli attacks on February 28 by effectively closing the Strait of Hormuz, a transit point for a fifth of the world's oil, through threats to tankers. Gulf oil exporters like Kuwait and Iraq cut production due to lack of access, resulting in the loss of 20 million barrels of oil daily—the "largest supply disruption in the history of the global oil market," per the International Energy Agency.
Brent crude oil prices climbed 3.4% on Friday to settle at $105.32 per barrel, up from roughly $70 pre-war, while benchmark U.S. crude rose 5.5% to $99.64. "Historically, oil price shocks like this have led to global recessions," warned Knittel.
The conflict has also revived fears of stagflation, a toxic mix of high inflation and low growth reminiscent of the 1970s oil shocks. "You're raising the risk of higher inflation and lower growth," said Carmen Reinhart, a former World Bank chief economist at the Harvard Kennedy School. Gita Gopinath, former IMF chief economist, projected that global economic growth, initially expected at 3.3% this year, could be 0.3 to 0.4 percentage points lower if oil averages $85 a barrel in 2026.
Fertilizer Shortages Threaten Global Food Security
The Persian Gulf accounts for a significant share of global fertilizer exports, including a third of urea and a quarter of ammonia. With up to 40% of world nitrogen fertilizer exports passing through the now-blocked Strait of Hormuz, prices have surged—urea up 50% and ammonia up 20% since the war began.
Big agricultural producers like Brazil, which imports 85% of its fertilizer, are especially vulnerable, according to Alpine Macro commodity strategist Kelly Xu. Egypt, a major fertilizer producer, faces production faltering due to natural gas shortages. Higher fertilizer prices are likely to make food more expensive and less abundant as farmers reduce usage, leading to lower yields and disproportionately impacting poorer nations.
Additionally, the war has disrupted world helium supplies, a byproduct of natural gas critical for chipmaking, rockets, and medical imaging, with Qatar supplying a third of global helium from the damaged Ras Laffan facility.
Developing Nations Bear the Brunt of Energy Rationing
"No country will be immune to the effects of this crisis if it continues to go in this direction," stated International Energy Agency head Fatih Birol on March 23. Poorer countries will be hit hardest, facing the biggest energy shortages "because they will be outbid when competing for the remaining oil and natural gas," explained Lutz Kilian, director of the Center for Energy and the Economy at the Federal Reserve Bank of Dallas.
Asia is particularly exposed, as over 80% of oil and LNG passing through the Strait of Hormuz is destined there. In response:
- Philippines government offices now operate four days a week with air conditioning limited to 75°F (24°C).
- Thailand has instructed public workers to use stairs instead of elevators.
- India, the world's second-largest importer of liquefied petroleum gas for cooking, is prioritizing households over businesses, with shortages forcing some eateries to shorten hours or drop energy-intensive dishes.
- South Korea has restricted car use by public employees and reinstated fuel price caps abandoned in the 1990s.
Vulnerable U.S. Economy Faces Mounting Pressures
The United States, while somewhat insulated as an oil exporter benefiting from higher prices, still grapples with economic vulnerabilities. Higher gasoline prices are weighing on consumers, with AAA reporting average prices rising to nearly $4 per gallon from $2.98 a month ago. "Nothing weighs more heavily on consumers' collective psyche than having to pay more at the pump," noted Mark Zandi, chief economist at Moody's Analytics.
The U.S. economy showed signs of weakness pre-war, expanding at an annual pace of just 0.7% from October through December, down from 4.4% in the previous quarter. Employers unexpectedly cut 92,000 jobs in February and added just 9,700 monthly in 2025, the weakest hiring outside a recession since 2002. Gregory Daco, chief economist at EY-Parthenon, has raised the odds of a U.S. recession over the next year to 40%, up from a normal risk of 15%.
Recovery Expected to Be Slow and Painful
Despite the world economy's resilience to past shocks like the pandemic and Russia's invasion of Ukraine, optimism about shrugging off the Iran war damage is fading as threats to Gulf energy infrastructure persist. "Some of the damage to LNG facilities in Qatar will likely take years to repair," said Kilian, highlighting additional repairs needed for refineries in Kuwait and tankers in the Gulf. "The process of recovery will be slow even under the best circumstances."
"There is no economic upside to the conflict with Iran," concluded Zandi and his colleagues. "At this point, the questions are how much longer the hostilities will continue and how much economic damage they will cause."
