Red Sea and Hormuz Chokepoints Tighten: Shipping Disruptions Reshape Energy and Agri-Bulk Trade

Escalating security risks around the Bab el-Mandeb Strait and the Strait of Hormuz are forcing tankers and bulk carriers to reroute, tightening vessel supply, extending voyage times and raising freight and insurance costs across key energy and agricultural trade lanes. While some crude flows are being maintained through targeted diplomatic efforts and alternative routes, overall capacity through these chokepoints has shrunk, with implications for import costs and delivery reliability into Asia, Europe and the Middle East.

Commodity and container market participants now face a rapidly evolving logistics landscape, as Houthi attacks and threats of a Saudi shipping embargo in the southern Red Sea coincide with a broader crisis over safe passage in Hormuz. Short-term disruptions are already visible in vessel counts through Bab el-Mandeb and in reconfiguration of Saudi export routes, with wider knock-on effects expected for grain, oilseed and feed markets that depend on the same ship pools and corridors as crude and refined products.

Introduction

Maritime traffic through the Bab el-Mandeb Strait has fallen sharply since Yemen’s Iran-aligned Houthi movement announced a blockade of Saudi-linked shipping on July 20, targeting tankers and other vessels in the southern Red Sea. Kpler data cited by multiple outlets show commodity vessel transits at this chokepoint dropping by more than half in the week after the embargo, to the lowest levels in months.

The disruption comes on top of an ongoing security crisis in the Strait of Hormuz, where pre-war daily traffic of more than 100 ships, including tankers carrying roughly 20 million bpd of crude, has been severely curtailed. As both ends of the Red Sea–Gulf corridor face heightened risk, exporters and importers of energy and agri-bulk commodities are scrambling to secure alternative routes, manage demurrage and reassess contract exposure.

Immediate Market Impact

Reduced tanker and bulk-carrier throughput at Bab el-Mandeb has slowed shipments between the Indian Ocean and the Mediterranean via Suez, prompting many shipowners to reroute vessels around the Cape of Good Hope. Analysts note that this significantly lengthens voyages and raises fuel consumption, squeezing effective fleet capacity and pushing up spot freight rates.

For now, some Saudi crude exports continue via the Red Sea using Yanbu and the SUMED pipeline to Sidi Kerir, and via the Suez Canal, partially offsetting the effective closure of Hormuz for some flows. However, the combination of Red Sea insecurity and Hormuz risk is fragmenting trade routes and raising risk premia on cargoes, with insurers increasing war-risk premiums and charterers facing higher freight, especially on Middle East–Asia and Black Sea–Asia corridors that also carry grain and oilseeds.

Supply Chain Disruptions

Attacks and attempted attacks on Saudi-linked vessels, including tankers such as NCC Masa, have reduced shipowners’ willingness to transit Bab el-Mandeb, driving a 50–60% slump in commodity vessel crossings at the strait in late July. This is already contributing to longer queues and congestion around alternative loading and discharge hubs, particularly in the eastern Mediterranean and at ports favoured by diversions around Africa.

Saudi Arabia and other Gulf exporters are increasingly utilising Red Sea terminals and pipelines to bypass Hormuz, while simultaneously seeing Bab el-Mandeb itself become riskier. The International Maritime Organization has previously coordinated partial evacuations from parts of Hormuz after attacks, underscoring the potential for further reductions in scheduled sailings and ad hoc port closures if security deteriorates.

China’s reported direct talks with the Houthis to secure safe passage for its tankers through the southern Red Sea highlight how some cargoes may gain preferential transit, while others face greater delays and risk. This differentiated access could distort voyage charter availability and freight pricing for third-country shippers, complicating logistics planning for agricultural importers in North Africa, the Middle East and South Asia.

Commodities Potentially Affected

• Crude oil and condensate – Core flows from Saudi Arabia and other Gulf producers rely on Hormuz and Red Sea routes; disruptions raise freight, insurance and prompt premiums, especially into Asia.
• Refined products and petrochemicals – Gasoline, diesel and petrochemical cargoes from Middle East hubs to Europe and Africa face longer, costlier routes as Bab el-Mandeb risk escalates.
• Wheat and coarse grains – Black Sea, EU and Russian grain shipments to East Africa and Asia, and Australian/Indian shipments to North Africa via Suez, are exposed to Red Sea disruptions and Cape of Good Hope diversions, lifting CIF costs.
• Oilseeds and vegetable oils – Flows of sunflower oil, rapeseed, soybeans and palm oil between the Black Sea, Europe and Asia often transit Suez; higher tanker and bulker rates can widen import parity levels and pressure downstream margins.
• Sugar and rice – Indian, Thai and Brazilian exports to the Middle East and North Africa face higher freight and longer transit times, affecting tender schedules and stock-cover strategies.

Regional Trade Implications

Asian buyers remain heavily exposed, as they import large volumes of crude and grains via Red Sea and Hormuz routes. While China may secure partial exemptions through direct engagement with the Houthis, other Asian importers could face relatively higher costs and longer lead times.

European and North African importers relying on Black Sea and EU grain arriving via Suez could see increased competition for alternative origins such as South America and the U.S. Gulf, particularly if sustained diversions tighten vessel availability. Gulf exporters with flexible pipeline access to the Mediterranean, like Saudi Arabia via SUMED, may retain a relative advantage, while Red Sea littoral states and trans-shipment hubs risk throughput losses.

Market Outlook

In the short term, freight and war-risk insurance premia are likely to remain elevated as long as missile and drone threats persist in both Bab el-Mandeb and Hormuz. Traders should expect increased basis volatility between FOB and CIF values, with particular sensitivity in East Africa, the Levant and South Asia where inventories are typically limited.

Key indicators to monitor include daily vessel counts through Bab el-Mandeb and Hormuz, any expansion or relaxation of the Houthi embargo on Saudi shipping, mediation efforts over navigation safety, and further evidence of large-scale rerouting around the Cape. Clearer security guarantees could normalise flows relatively quickly, but a prolonged standoff would further tighten effective shipping capacity and embed higher logistics costs into forward price structures.

CMB Market Insight

The concurrent stress on both the Red Sea corridor and the Strait of Hormuz represents a structural shock to global commodity logistics rather than a short-lived weather-style disruption. For agricultural and food-industry players, the immediate transmission channel is higher and more volatile freight, feeding into landed prices and occasionally into availability in import-dependent regions.

Strategically, traders and procurement teams should reassess exposure to Red Sea and Hormuz routes in their forward books, diversify origins where possible, and build greater flexibility into contract delivery options. In an environment where geopolitical risk is directly constraining sea-lane capacity, competitive advantage will increasingly depend on agile routing, diversified shipping counterparts and proactive inventory management.
