The ongoing US-Israel war against Iran has sent shockwaves through global financial markets, pushing oil prices above $103 per barrel, triggering sharp selloffs in stock markets across Asia, Europe and the United States, and forcing dozens of international airlines to suspend or reroute flights. As the conflict enters its eleventh day on March 11, 2026, economists and analysts warn that the world may be on the brink of a major economic disruption not seen since the COVID-19 pandemic.

When the US and Israel launched coordinated strikes on Iran on February 28, 2026, oil markets reacted with immediate ferocity. Brent crude futures surged by as much as 29 percent in early trading on March 2, reaching a peak of $119.50 per barrel — their highest level since mid-2022. Though prices pulled back somewhat after initial panic, Brent has continued to trade above $103 per barrel as of March 11, with WTI crude holding at $101.97.

The scale of the price movement reflects deep anxiety in energy markets. The Strait of Hormuz, through which approximately 20 percent of the world’s oil supply passes daily, remains under severe threat. The United States Navy has already engaged and destroyed 16 Iranian naval vessels in the strait, and Iran has threatened to mine the waterway if the conflict continues to escalate. Qatar’s energy minister has warned that if hostilities persist without resolution, all Gulf energy exporters may halt production entirely, potentially sending oil prices to $150 a barrel.

Saudi Arabia and other OPEC nations have also cut output, citing a lack of storage capacity. Kpler consultants have estimated that storage facilities in Saudi Arabia and the UAE could reach maximum capacity within 20 days, which could force yet more painful production cuts. Analysts at CNBC quoted energy experts saying the “sky is the limit” for oil prices if the conflict is not contained.

Global equity markets have been thrown into turmoil. The sharpest single-day plunge came on March 2, when the Dow Jones Industrial Average briefly fell more than 1,200 points in intraday trading before recovering to close down 404 points. The S&P 500 fell 0.94 percent and the Nasdaq dropped 1.02 percent on that day alone. Collectively, more than $3.2 trillion in global market capitalization was wiped out within 48 hours of the initial strikes on Iran.

In India, the Sensex and Nifty experienced sharp declines. Investor sentiment was hit by multiple factors simultaneously — rising crude oil import costs, currency depreciation, and fears of prolonged supply disruptions. India imports more than 85 percent of its crude oil requirements and is acutely sensitive to any major upward movement in global oil prices. The Reserve Bank of India has been monitoring the situation closely, with experts warning that sustained high oil prices could widen India’s current account deficit significantly and put renewed pressure on the Indian rupee.

In Asia, markets in Japan, South Korea, Hong Kong and China also fell sharply in early March, though they have since partially recovered as investors attempt to assess whether the conflict will be short-lived or prolonged. In Europe, the FTSE 100, CAC 40 and DAX all saw week-on-week losses of between 3 and 5 percent. Investors have rushed into safe-haven assets such as gold, US Treasury bonds, and the Swiss franc, while dumping equities and currencies from emerging markets.

The aviation sector has been among the hardest hit. The closure of Iranian airspace and broad restrictions across Middle Eastern airspace triggered a cascade of cancellations and suspensions from airlines across the world. Air India was among the first to announce the suspension of international flights transiting through Middle Eastern airspace, with cancellations beginning on March 1. IndiGo followed suit, suspending 158 flights on March 3 alone and extending the suspension through multiple rounds.

Major international carriers also pulled back. Air France, Emirates, Etihad, and Turkish Airlines all announced suspensions of routes over or near Iran, Iraq, Lebanon, Syria and Jordan. Turkish Airlines cancelled services to multiple Middle Eastern destinations through early March. Passengers across the globe were left stranded or facing massive itinerary disruptions as airlines scrambled to reroute flights over longer, more expensive paths that avoided the affected airspace.

The cost of rerouting is significant. Flights from India to Europe that would normally transit over the Gulf and the Arabian Peninsula are now being redirected northward over Central Asia, adding hours to journey times and thousands of litres to fuel consumption. Analysts have warned this will translate into higher airfares for passengers in coming weeks and months, just as the summer travel season approaches.

Low-cost carriers operating in the South Asian and Southeast Asian markets that depend on affordable Middle East route access are particularly exposed. SpiceJet, IndiGo and AirAsia have all faced elevated operational costs and reduced revenues due to route cancellations. Aviation industry body IATA has called for an urgent international diplomatic resolution to restore safe airspace access.

Global Inflation Fears Intensify

The economic consequences of the Iran war extend far beyond oil and aviation. Analysts and central banks worldwide are now grappling with the prospect of a significant inflation spike driven by energy prices. The Guardian reported that Brent crude at $91 per barrel — the level reached by early March — already represented the largest weekly gain for oil since the early weeks of the COVID-19 pandemic. With prices now above $100, pressure on consumer prices is intensifying.

Food inflation is a particular concern. Fuel costs are embedded throughout modern food supply chains — from fertiliser production and farm mechanisation to transport, cold storage and retail distribution. Any sustained period of high fuel prices is expected to push grocery costs higher, especially in developing economies that are also vulnerable to currency depreciation as their import bills rise.

Many economists are now raising the probability of a global recession in 2026. The trigger of the US-Israel-Iran war has upended what had been a relatively stable post-pandemic recovery. Central banks in the US, Europe and India face a particularly difficult policy environment — they may need to raise interest rates to fight inflation even as growth is threatened by energy price shocks, creating a classic stagflation scenario.

India’s Economic Vulnerability

For India, the implications of sustained high oil prices are severe. India’s oil import bill for 2025-26 was already budgeted at over $130 billion. If Brent crude remains above $100 for an extended period, India’s import bill could surge by an additional $30-40 billion, putting enormous pressure on foreign exchange reserves, the trade deficit, and ultimately the rupee.

The government has already been forced to manage an LPG supply crisis, with commercial cylinder allocations being halted to prioritise domestic household consumers. Petrol and diesel prices at the pump have not been revised upward yet, with the government absorbing the cost differential through oil marketing companies. Analysts, however, warn that this strategy cannot continue indefinitely if crude prices remain elevated, and that a revision in retail fuel prices may become unavoidable.

The Federation of Indian Chambers of Commerce & Industry (FICCI) and the Confederation of Indian Industry (CII) have both issued statements calling on the government to expedite India’s transition to domestic renewable energy to insulate the economy from future oil shocks. In the meantime, sectors such as transport, logistics, aviation, manufacturing and agriculture are all bracing for higher input costs.

Conclusion

The Iran war has rapidly transformed from a geopolitical crisis into a full-blown economic emergency. With oil above $100 a barrel, stock markets in turmoil, airlines grounding flights, and inflation fears mounting globally, the ripple effects of the US-Israel-Iran conflict are touching every corner of the world economy. For countries like India that are heavily dependent on imported energy, the coming weeks will be a critical test of economic resilience. The world watches anxiously as diplomats and military commanders alike seek a path out of a conflict that threatens not just lives in the Middle East, but livelihoods everywhere.
