Middle East Conflict Deepens Energy Shipping Crisis as Hormuz and Red Sea Chokepoints Disrupted

Escalating conflict involving the United States, Israel, Iran and Iran‑aligned groups has pushed Middle Eastern energy logistics into an acute crisis, with simultaneous disruptions around the Strait of Hormuz and the Red Sea/Bab el‑Mandeb corridor. Attacks, blockades and military blockades are constraining Gulf crude and product flows, rerouting tankers, and lifting risk premiums across oil and LNG trade.

The Strait of Hormuz, normally carrying about 20% of globally traded oil, has been effectively closed to most Gulf exporters since late February, while Yemen’s Houthi movement has declared a maritime blockade on Saudi shipping through the Red Sea and Bab el‑Mandeb. Combined, these twin chokepoint disruptions are reshaping seaborne flows, lengthening voyage times and amplifying volatility in crude, product and related commodity markets.

Introduction

The US‑Israel war with Iran has triggered repeated missile and drone exchanges across the region and direct strikes on energy and port infrastructure, including around the Strait of Hormuz and Saudi Arabia’s Red Sea coast. Iran has used its geographic position to restrict traffic through Hormuz, while also supporting proxy groups such as Yemen’s Houthis, who are targeting Saudi oil facilities and shipping lanes in the Red Sea.

In recent days, Houthi forces have claimed attacks on Saudi oil tankers and Red Sea export terminals and announced a blockade on Saudi shipping, while missile incidents and explosions have been reported along key transit routes. For commodity markets, this is not a localized security issue but a systemic supply‑chain shock affecting core crude, products and potentially petrochemical and fertilizer flows out of the Gulf.

Immediate Market Impact

Oil prices have swung sharply as traders reassess the scale and duration of supply risk. Brent surged above $100 per barrel last week as Red Sea attacks intensified, before easing below $90 after a short‑lived pause in US‑Iran strikes, underscoring extreme headline‑driven volatility. Refining margins have widened as product buyers price in higher freight and insurance costs on Middle East‑linked routes.

With Hormuz traffic largely halted for non‑Iranian exporters, Gulf producers are diverting barrels through alternative pipelines and west‑coast ports where possible, notably Saudi Arabia’s Yanbu and other Red Sea terminals. However, Houthi attacks and the declared blockade on Saudi shipping now directly threaten these work‑around corridors, reducing effective spare export capacity and pushing more trade onto longer Atlantic Basin or overland routes.

War‑risk insurance premia for tankers transiting Hormuz, the Gulf of Oman and the southern Red Sea have risen multiple‑fold since the onset of hostilities, while ship‑to‑ship transfer activity in safer waters has slowed amid heightened naval confrontation and operational complexity. The net effect is a higher delivered cost of crude and products into Europe, Asia and emerging markets, even where underlying FOB prices are temporarily capped by demand concerns.

Supply Chain Disruptions

Port and transit disruptions span both ends of the Arabian Peninsula. In the Gulf, Iranian attacks on commercial vessels and the US blockade of Iranian ports have left hundreds of ships and thousands of mariners stranded or rerouting away from Hormuz and the Gulf of Oman. In the Red Sea, strikes on Saudi oil terminals and tanker traffic near Bab el‑Mandeb are creating localized congestion and forcing operators to suspend or reprogram sailings.

Saudi Arabia, which had been using its East‑West pipeline to move crude from Gulf fields to Red Sea ports, is reported to have halted crude loadings through Bab el‑Mandeb since the Houthi maritime embargo took effect, curtailing one of the principal bypass routes for Hormuz. Maritime advisories now classify Saudi Red Sea calls as high risk, with some vessels executing mid‑voyage U‑turns rather than proceed through threatened waters.

These constraints are lengthening voyage distances as some Atlantic Basin and Asian buyers shift to cargoes from the Americas, West Africa or North Sea, while others attempt circuitous routings to avoid the Red Sea or Gulf chokepoints. The additional days on the water tie up tanker capacity, tighten the freight market, and reduce effective seaborne availability of both crude and refined products.

Commodities Potentially Affected

• Crude oil: Core impact as Hormuz and Red Sea flows are curtailed or rerouted, reducing prompt availability from Saudi Arabia and other Gulf producers and widening regional price differentials.
• Refined products (diesel, gasoline, jet fuel): Disrupted product exports from Middle East refineries into Europe, Africa and Asia, plus higher freight and war‑risk costs, support stronger cracks and regional shortages.
• LNG: Although less visible in spot pricing, LNG cargoes using Hormuz and Red Sea routes face similar security and insurance constraints, potentially tightening supply into South and East Asia and the Mediterranean.
• Fuel oil and bunker markets: Longer voyages and re‑routing increase bunker demand at alternative hubs, while disrupted residual fuel exports from the region may tighten supply for shipping and power generation in import‑dependent states.
• Agricultural commodities: While not directly targeted, Black Sea and Middle East‑bound grain and fertilizer shipments may experience congestion and higher freight rates as they compete for limited safe transit capacity and insurance coverage.

Regional Trade Implications

Traditional Gulf suppliers to Europe and Asia risk losing market share in the near term to producers whose exports are less exposed to these chokepoints. North Sea, US Gulf Coast, West African and Brazilian crude streams are well placed to backfill lost Middle East barrels, particularly into Europe and the Atlantic Basin.

Conversely, major importers heavily reliant on Gulf supplies via Hormuz and Bab el‑Mandeb – including India, some ASEAN economies, and Red Sea littoral states – face sharper price and supply‑security pressures. Refiners in these regions may be forced into more distant sourcing, term renegotiations, and increased use of storage to buffer against shipment delays.

Within the Middle East, Iran’s continued ability to sell some crude, notably to China, even as it restricts Gulf neighbors’ exports, is reshaping intra‑regional trade dynamics and bargaining power. Egypt and other Suez‑adjacent economies could see reduced canal tolls and higher import costs if Red Sea transits fall materially, adding macroeconomic strain in already fragile contexts.

Market Outlook

In the short term, traders should expect episodic price spikes, sharp intraday reversals and elevated time‑spreads as newsflow around missile exchanges, blockades and naval escorts drives sentiment. The market is primed for risk‑on moves whenever there are fresh disruptions at Hormuz or Bab el‑Mandeb, but also for rapid corrections on any sign of de‑escalation or new escort arrangements.

Structurally, sustained closure or partial impairment of one or both chokepoints would entrench higher baseline freight and war‑risk costs, encourage a more diversified sourcing mix for refiners, and elevate the strategic premium on inventories and optionality in term contracts. Traders are closely monitoring tanker traffic data, war‑risk pricing, Saudi export patterns via Red Sea ports, and any diplomatic moves toward securing dedicated maritime corridors.

CMB Market Insight

The overlapping disruptions at the Strait of Hormuz and the Red Sea mark a profound stress test for global energy logistics, with direct spillovers into broader commodity supply chains. For now, volumes continue to flow via costlier, longer and less efficient routes, but with reduced redundancy and thinner margins for error.

Commodity participants should assume a prolonged period of elevated geopolitical risk premia and structurally higher delivered costs on Middle East‑linked barrels. Strategic priorities will include diversifying origin portfolios, strengthening shipping and insurance arrangements, and building greater flexibility into supply contracts and inventory management to navigate a new, more fragmented geography of risk.
