The global economy is taking its hardest hit since the pandemic, and you can trace the damage directly back to the conflict involving Iran. According to the June 2026 Global Economic Prospects report from the World Bank, global economic growth is projected to slow to a bleak 2.5% this year. That is a sharp drop from the 2.9% expansion we saw in 2025.
If you are wondering why your local gas prices are creeping back up or why everyday goods feel expensive again, this is the root cause. The U.S.-led war in Iran, which kicked off with joint strikes alongside Israel on February 28, has slammed the brakes on international commerce. The real gut punch came when Iran effectively closed off the Strait of Hormuz. It sparked what economists call the biggest supply shock in 50 years.
The Strait of Hormuz Bottleneck
When you choke off a channel that handles roughly a fifth of the world's liquid energy, bad things happen fast. Tankers are stuck. Routes are being redrawn.
The immediate result is a massive spikes in energy and commodity markets. The World Bank expects global benchmark Brent crude to average $94 a barrel this year. That is a massive 36% jump compared to 2025. It is also a staggering 50% higher than what economists predicted back in January before the missiles started flying.
This is not just about the cost to fill up a car. The Persian Gulf is a massive hub for exporting fertilizer inputs. Because of the shipping blockade, global fertilizer prices are on track to skyrocket by up to 38% this year. When fertilizer gets expensive, farmers use less of it. When farmers use less of it, crop yields drop, and grocery prices surge. Global inflation is now expected to hit 4.0% this year, up from 3.3% in 2025.
Why the Pain is Unequal
The slowdown is hitting different regions in wildly asymmetrical ways. The World Bank downgraded its growth forecasts for two-thirds of the world's nations. Yet, a few major players are holding their ground, creating a stark divide.
The Western Cushion
The United States is proving surprisingly resilient, though ordinary citizens are still hurting at the pump. The World Bank held its U.S. growth forecast steady at 2.2% for 2026. Why? The U.S. is a major energy producer itself, which protects it from the worst of the import shocks. Plus, a massive wave of capital investment in artificial intelligence infrastructure has kept the American business engine humming.
The Developing World Slump
Developing and emerging economies do not have that luxury. Their growth forecast has been slashed to a post-pandemic low of 3.6%.
- The Gulf States: Nations right next to the conflict zone like Kuwait, Iraq, and Qatar are facing near-zero growth this year. The United Arab Emirates is expected to grow at 2.4%, less than half of its pre-war pace.
- China: The world's second-largest economy is feeling the chill, with growth downgraded to 4.2% down from 5% last year.
- Europe: Already fragile, the Euro area is expected to crawl along at a miserable 0.8% growth rate.
- India: It remains a bright spot as the fastest-growing major economy at 6.6%, but even that is a big step down from the 7.7% it pulled off last year.
World Bank Chief Economist Indermit Gill did not mince words in the report. He warned that without some sort of miracle, the 2020s are officially tracking to become a lost decade for developing nations. Roughly half of these countries have made zero progress in closing the income gap with wealthy nations since 2019.
High Debt Meets Fraying Safety Nets
During the 2008 financial crash and the 2020 pandemic, governments around the world simply printed and spent trillions of dollars to keep their economies afloat. This time, they cannot.
The timing of this geopolitical shock is brutal. Aggregate government debt in developing nations has ballooned from 40% of GDP in 2010 to 70% today. Wealthier nations are also drowning in red eyes and running massive budget deficits.
Because central banks like the Federal Reserve are forced to keep interest rates elevated to battle this new wave of war-driven inflation, borrowing money has become incredibly expensive. Developing nations are spending a combined $8 trillion annually just to service their existing debts. When more than a third of a government budget goes to paying interest to foreign lenders, there is nothing left to subsidize food, build roads, or protect citizens from economic ruin.
The World Bank is trying to patch the holes, opening up a $50 billion to $60 billion emergency financing facility, which could scale up to $100 billion over the next 15 months. But that is a band-aid on a gaping wound.
How Bad Could It Get
The current 2.5% growth forecast assumes a major "if." It assumes the nominal ceasefire holds and the shipping logjams in the Strait of Hormuz start clearing out by the end of July.
But things on the ground look incredibly fragile. If hostilities escalate or the blockade drags through autumn, the World Bank’s downside scenario kicks in. In that case, crude oil prices will shoot up to an average of $115 a barrel. Global growth would plummet to a miserable 1.3%. That kind of slowdown would trigger widespread corporate bankruptcies, deep financial market stress, and outright recessions across multiple continents.
Navigating the Fallout
If you are managing a business or trying to protect your personal capital right now, waiting around for global leaders to sort out the Middle East is a bad strategy. The macro picture is messy, but the micro choices are still ours to make.
Focus heavily on supply chain insulation. If your business relies on products or components that pass through global maritime chokepoints, start looking into domestic or regional alternatives immediately, even if the upfront cost is slightly higher.
Review your capital structure. With inflation staying sticky at 4%, don't expect central banks to cut interest rates anytime soon. Cash is no longer trash when borrowing costs are high and markets are volatile. Pay down variable-rate debts and keep liquid reserves robust enough to survive a protracted dry spell. The global economy is downshifting sharply, and the groups that survive are the ones built to handle the bumps.
