The joint U.S.-Israeli military campaign against Iran, launched on Feb. 28 and targeting the country’s leadership, including the Supreme Leader Ali Khamenei, its nuclear program and its missile infrastructure, has rapidly escalated into a full regional crisis.
Iran has retaliated with missile and drone strikes across the Gulf, and on March 2 the Islamic Revolutionary Guard Corps formally declared the Strait of Hormuz closed, threatening to strike any vessel attempting transit and bringing commercial traffic to a near-standstill in the world’s most critical energy chokepoint.
Compounding the disruption, Houthi-controlled Yemen simultaneously resumed attacks in the Red Sea, closing the Suez corridor – the primary artery for container trade between Asia and Europe – and forcing global rerouting via the Cape of Good Hope.
With Iran threatening to strike ships passing through the strait, U.S. President Donald Trump yesterday, March 3, ordered the U.S. Development Finance Corp. to provide political risk insurance and guarantees for all maritime trade, in particular energy, at a “very reasonable price.” The DFC issued a statement saying it stands ready to support commercial shipping charterers, shipowners and key maritime insurance providers to minimize market disruptions and help ensure the free flow of goods and capital.
Trump, who initiated the war alongside Israel on Feb. 28 to eliminate “imminent threats” from Iran, said the U.S. Navy could escort tankers through the Strait of Hormuz if required.
In the case of a four- to five-week disruption, the impact would likely be confined to spot commodity spikes. However, a prolonged disruption to the Strait of Hormuz, through which approximately 20% of global oil, 25% of global liquefied natural gas, or LNG, and aluminum exports flow, would create cascading supply, cost and demand shocks across global high-yield credit sectors, while simultaneously inflating shipping rates and adding weeks of transit time as containers, tankers and other vessels re-route via the Cape of Good Hope, with the severity and transmission mechanism varying materially by industry and duration of conflict. Some of the key commodities affected are below:
- Oil: About 20 MMbl/d of crude passes through Hormuz, representing approximately 20% of global consumption. Short disruptions typically add a $15bbl to $25bbl risk premium to Brent, with sustained closure potentially pushing prices above $100/bbl, on analyst estimates. European petrochemical refiners such as Ineos would face crude slate disruption, particularly those configured for Gulf medium-sour grades. However, the U.S. is no longer a meaningful direct importer of Gulf crude. The U.S. Energy Information Administration reported that U.S. oil imports through the Strait of Hormuz only accounted for about 7% of total crude oil and condensate imports and 2% of petroleum liquids consumption in 2024.
- LNG/Gas: Roughly 20% of global LNG trade – largely Qatari volumes transits Hormuz. QatarEnergy halted production at Ras Laffan and Mesaieed, sending European Title Transfer Facility, or TTF, prices up over 50%. U.S. LNG exporters Cheniere and Venture Global, in particular, are the primary beneficiaries, with both stocks rallying sharply on the supply gap. However, U.S. export shipping cargoes are already running near capacity, limiting the ability to meaningfully offset lost Qatari volumes. With TTF prices moving higher, energy-intensive sectors such as glass, aluminum and petrochemicals would be most exposed. U.S. energy-intensive industries are less exposed than European peers given domestic gas supply, but logistics, packaging and chemical names with global supply chains face secondary cost inflation.
- Petrochemicals: The Gulf supplies roughly 30% to 40% of Europe’s crude for naphtha production, the key feedstock for steam crackers producing ethylene, propylene, butadiene and aromatics. In the U.S., the structural advantage of ethane-based cracking insulates domestic producers from direct naphtha feedstock disruption. However, global petrochemical pricing is interconnected, Octus estimates European inventories cover about 20 to 25 days of naphtha demand, and any prolonged disruption would therefore tighten supply across the C2 – C4 and aromatics chains, feeding through to downstream chemicals such as polymers, styrene, MMA and nitrile rubber on both sides of the Atlantic. Gulf producers also supply roughly 40% to 50% of Europe’s monoethylene glycol, or MEG, a key polyethylene terephthalate, or PET, input.
- Aluminum: United Arab Emirate and Bahrain smelters produce around 4 to 5 metric tons of aluminum annually, roughly 4% to 6% of global supply, all shipped through Hormuz. Europe sources around 30% of its aluminum imports from the Middle East, dominated by the UAE, leaving European premiums especially sensitive given already tight primary availability. The Qatalum smelter in Qatar, is going through a controlled shutdown with a restart timeline of approximately three to six months. In the United States, the direct import exposure to Gulf aluminum is lower, but a sustained rally of global aluminum prices or the Midwest premium, the excess of U.S. aluminum prices above global aluminum prices, could raise input costs for aluminum processors and packaging issuers that are able to contractually pass through regional aluminum costs to their customers in most cases.
The chart maps the petrochemical value chain from primary hydrocarbon feedstocks through to end-use applications. Crude oil and natural gas are first processed through refining and steam cracking, producing two core chemical families: olefins, such as ethylene, propylene, C4 streams and pygas, and aromatics, including benzene, toluene and xylenes.
These base chemicals then flow into successive tiers of intermediates, including polymers, synthetic rubbers, resins and industrial solvents. Downstream conversion ultimately feeds a broad set of end markets, most notably packaging, automotive components, textiles, construction materials and a range of consumer goods.
We outline the direct sector-level transmission of the disruption below:
- Oil & Gas: Approximately 20% of global oil trade and 25% of global liquefied natural gas trade transits the Strait of Hormuz. Upstream producers with no direct Gulf operations (North Sea, West Africa) benefit from an immediate uplift in Brent. Midstream and downstream operators face margin volatility as crude input costs spike faster than refined product pricing adjusts. European refinery margins could widen on product scarcity. Gas-linked names see knock-on effects through liquefied natural gas pricing and European TTF benchmarks, with industrial and power generation costs rising across the continent.
- Exploration & Production: No physical Hormuz exposure but is an indirect beneficiary through Brent pricing. Revenue uplift is meaningful, though partially capped by hedge books in the short term. The key risk of extended conflict durations is the divergence between strong spot economics and impaired capital market access as broader high-yield risk aversion tightens. In the United States, natural gas E&P likely benefits less than its oil-levered peers, as Henry Hub is a domestically driven benchmark, largely insulated from a global TTF spike and an Asian LNG premium (Japan Korea Marker) spike that a Hormuz LNG disruption triggers.
- Petrochemicals & Chemicals: European naphtha crackers source 30% to 40% of feedstock from Gulf refineries. Naphtha crackers cannot substitute for ethane, and co-products (propylene, butadiene, aromatics) have no alternative production route. A sustained disruption would create structural shortages in propylene, butadiene and the aromatics complex (benzene, toluene, xylene) across the entire European chemical value chain. Conversely, North American natural gas prices have been essentially unchanged, significantly widening the energy cost advantage for North American commodity chemical producers.
- Foundry Chemicals: Exposure runs through the phenol chain (the cumene process requires benzene and propylene, both Gulf-dependent feedstocks). Supply shock and demand shock are self-reinforcing: Feedstock becomes unavailable while automotive and industrial casting volumes decline simultaneously.
- Packaging & Metals: PET producers face direct MEG exposure, with Gulf producers accounting for an estimated 40% to 50% of European supply, a concentration that leaves limited short-term substitution optionality. Primary aluminum producers benefit from higher aluminum prices and largely stable alumina costs, while the aluminum processors are relatively insulated through cost pass-through contracts and expanding scrap spreads. Aluminum can producers are largely able to pass higher metal costs to customers, while higher-energy costs could disproportionately inflate production costs for competing substrates – glass and PET in particular – improving the relative cost position of aluminum packaging.
- Shipping: This conflict would sharply increase tanker insurance costs and potentially force other ships, such as containers, tankers and dry bulk, to reroute around the Cape of Good Hope, adding 10 to 14 days to voyages.
- Travel & Leisure: Jet fuel is 25% to 35% of airline operating costs. A $15 to $25 per barrel Brent spike flows directly to the profit and loss, partially offset by hedging. At longer durations, consumer demand destruction hits discretionary travel spend, compounding the cost shock. Travel gets hit first by fuel and disruption, and only later by demand. Rerouting and airspace closures push up fuel burn and reduce aircraft utilization, while war risk insurance and handling costs reprice fast.
- Automotive: Automotive production is energy-intensive where natural gas and electricity are major input costs. Any sustained disruption to petrochemical feedstock supply chains would flow through to polymer pricing and, by extension, to vehicle production costs. In addition, Europe sources an estimated 20% to 30% of its primary aluminum imports from the Middle East, with the UAE as the dominant supplier. With Russian aluminum simultaneously being phased out under European Union sanctions, disruption to Middle East supply would compound an already tight market. Between Feb. 27 and March 4, aluminum prices climbed about 6% to $3,342.
