Which Countries Could Benefit Most from a Prolonged U.S.-Israel-Iran Conflict?

Wars do not create winners in any moral sense. But markets do create relative beneficiaries. As of March 7, 2026, that question is no longer abstract: the latest U.S.-Israel-Iran escalation has already disrupted shipping around the Strait of Hormuz, pushed Brent above $90 at points this week, and prompted Barclays to warn that a prolonged crisis could test $120 a barrel, with more extreme outcomes possible if disruption spreads. That matters because the Strait handled nearly 20 million barrels a day of oil exports in 2025 and about one-fifth of global LNG trade.

The first mistake is assuming the biggest beneficiaries would be the Gulf producers closest to the conflict. In a short, contained flare-up, maybe. In a prolonged war, probably not. The IEA estimates that only about 3.5 to 5.5 million barrels a day can bypass Hormuz through Saudi and UAE pipelines, and Reuters reports Saudi rerouting through the Red Sea still does not fully replace lost flows. LNG is even more vulnerable: the IEA says 93% of Qatar’s and 96% of the UAE’s LNG exports normally pass through Hormuz, with no alternative route to market.

That is why the likely winners sit farther from the battlefield, in countries that can sell energy or strategic insurance while keeping their own export routes open.

If the conflict drags on, Russia is still the most obvious relative beneficiary. AP and Reuters both note that Russian crude is now above the $59-per-barrel assumption used in Moscow’s 2026 budget, and oil and gas tax revenues account for as much as 30% of the federal budget. Carnegie has also argued that a Middle East war can help Moscow narrow its fiscal gap by lifting oil prices, even if it simultaneously weakens one of Russia’s regional partners. In plain English, every barrel that cannot leave the Gulf makes Russian barrels more valuable.

It also complicates sanctions politics. Washington’s recent 30-day waiver allowing India to buy stranded Russian oil was explicitly aimed at easing pressure on global prices, which shows how quickly anti-Russia discipline can soften when crude spikes.

Norway may be the cleanest safe-haven exporter in this scenario. Reuters reports that Norway produces about 2% of global oil, supplies roughly 30% of Europe’s gas demand, and about 20% of Europe’s oil. If Europe is trying to reduce reliance on both Russian supply and unstable Gulf flows, Norwegian barrels and molecules become even more strategically important.

That is what makes Norway different from the Gulf states. It benefits from the same higher-price backdrop, but without sitting under the same missile umbrella or depending on Hormuz. For markets, that mix of security and scale is rare.

Canada is not usually the first country mentioned in Middle East crisis discussions, but it should be. Reuters reported this week that the Iran conflict pushed U.S. Gulf Coast heavy crude prices to their highest premiums since 2020 as refiners scrambled to replace tighter Persian Gulf medium and heavy grades. The same squeeze has helped Canadian oil sands crude, while energy stocks helped lift Toronto’s TSX to record highs as oil and gas prices surged.

The logic is straightforward. When Gulf barrels disappear or become politically risky, refiners look for similar quality elsewhere. Canada cannot replace the Gulf at full scale, but it does not need to. It only needs to be one credible alternative, and in a prolonged disruption that is enough to improve pricing, cash flow, and export income.

Brazil is well positioned because its crude can reach Europe and Asia without touching Hormuz. Petrobras said this week that higher oil prices could improve cash flow, even if management is cautious about calling that an unqualified upside. In a long conflict, Brazil’s appeal rises because buyers want large non-Middle East barrels from safer shipping lanes.

Brazil’s advantage is not just geography. It is timing. In a tighter market, refiners pay up for reliable supply with fewer geopolitical strings attached, and Brazil fits that profile far better than most producers inside the Gulf.

Guyana is smaller than Brazil, but in market terms it may be the highest-beta beneficiary. The government expects the economy to grow 16.2% in 2026, with oil output averaging about 840,000 barrels a day, and Reuters data show Europe already took 66% of Guyana’s crude exports in 2024. That means Guyana is no longer just a future story. It is already a real Atlantic supply source for buyers looking to reduce exposure to the Gulf.

For a small economy, even modest shifts in price and demand can have an outsized macro effect. That is why Guyana may not be the biggest winner in absolute dollars, but it could be one of the biggest winners relative to its size.

It would be misleading to call the United States a net national winner from a long war with Iran. The military cost, inflation risk, and political burden are real. But sectorally, the U.S. still gains. The EIA says the country is now the world’s largest LNG exporter, with exports rising to 15.0 Bcf/d in 2025, and Reuters reports U.S. crude output is hovering around record levels while U.S. Gulf heavy crude prices have surged as global refiners hunt non-Gulf supply.

So the better way to frame it is this: America would not “benefit” as a whole, but the U.S. energy complex could. For investors, that distinction matters. National pain and sectoral upside can exist at the same time.

China, India, Japan, and South Korea are more likely to suffer than gain. The IEA says China and India together received 44% of crude moving through Hormuz in 2025, and Reuters reports that Asia and Europe are the regions most exposed to LNG disruption if the strait stays shut. That is why the lazy argument that “Asia benefits because Washington is distracted” misses the energy math. For the big Asian importers, a prolonged conflict means higher import bills, tighter LNG markets, and slower growth.

The same caution applies to Saudi Arabia, the UAE, Qatar, and Kuwait. They may enjoy a brief price spike, but they are too exposed to infrastructure attacks and shipping bottlenecks to count as durable winners in a genuinely prolonged war. High prices do not help much if the export route itself is broken.

The countries most likely to benefit from a prolonged U.S.-Israel-Iran conflict are not the ones on the front line. They are the exporters with secure shipping lanes and the ability to sell substitute energy into a nervous market. Russia remains the clearest relative winner. After that, Norway, Canada, Brazil, and Guyana look better positioned than the Gulf itself. The longer the conflict lasts, the more the advantage shifts away from proximity and toward distance, logistics, and pricing power.
