According to WPB, the Red Sea is becoming a more difficult answer to the Strait of Hormuz problem. Attacks reported on August 9 against Saudi Arabia’s Jazan refinery and Yemen’s Mocha port have put new pressure on a corridor that Gulf exporters increasingly depend on when normal shipping through Hormuz becomes unreliable. The immediate physical damage appears contained at Jazan, but the broader message for energy and bitumen markets is harder to ignore: the alternative route itself is now carrying a growing security premium.
Yemen’s Houthis said they used a drone to strike Saudi Aramco’s Jazan refinery on the southwestern Red Sea coast. Saudi Arabia’s energy ministry confirmed that a fire broke out at the refinery and said it was extinguished without injuries, but the ministry did not publicly attribute the fire to a Houthi attack. That distinction matters. The Houthi claim and the confirmed fire occurred at the same facility, but Saudi authorities have not independently confirmed the stated cause.
Jazan is a major refining complex with design capacity of up to 400,000 barrels per day. The facility is built as a full-conversion refinery producing transportation fuels and petrochemical feedstocks, while its integrated configuration can process lower-value heavy refinery streams through gasification.
There is another important detail: the refinery had already been shut since late July following an earlier Houthi attack. Industry information reported on July 28 indicated that the 400,000-bpd facility was shut on July 27 after the previous strike. That means the August 9 incident should not automatically be interpreted as a fresh loss of 400,000 barrels per day of operating refinery capacity. The more immediate significance is the continued ability to threaten a major Saudi energy site on the Red Sea coast and potentially delay its return to normal operation.
At almost the same time, the Houthis launched missile and drone strikes against Mocha, a Yemeni port city near the Bab el-Mandeb Strait. Yemeni government sources said drones were directed toward the commercial quay and storage areas, while the country’s transportation ministry reported severe damage to port infrastructure.
The latest casualty update adds to the scale of the incident. By early August 10, the Yemeni military said seven people — four members of the armed forces and three civilians — had been killed and 30 wounded. It also said air defenses intercepted 11 drones involved in the attack and that residential areas were hit.
For energy markets, Mocha matters less because of the volume of oil handled there and more because of its location.
The port sits close to Bab el-Mandeb, the narrow gateway connecting the Red Sea with the Gulf of Aden and Indian Ocean. A strike on Mocha does not mean Bab el-Mandeb itself has been closed, and the two should not be treated as the same event. But repeated missile and drone activity around the southern Red Sea changes the commercial risk assessment for vessels that must pass nearby. A serious closure of Bab el-Mandeb would undermine one of Saudi Arabia’s main alternatives to Hormuz. That is what makes the August 9 attacks particularly important.
Saudi Arabia possesses one of the strongest physical options in the Gulf for bypassing Hormuz. Its East-West crude pipeline carries oil from the Abqaiq area in the east across the country to Yanbu on the Red Sea. The system has historically had about 5 million barrels per day of normal crude capacity and has been expanded to as much as 7 million barrels per day through conversion of additional pipeline infrastructure.
Since the current Hormuz disruption intensified, that system has become far more strategically valuable. Saudi Arabia can move crude overland instead of sending it by tanker through Hormuz, then load it at Yanbu for international customers. In theory, this solves the first chokepoint problem. But it does not eliminate geography.
A tanker leaving Yanbu for Asia normally still has to sail south through the Red Sea and pass Bab el-Mandeb before entering the Gulf of Aden and Indian Ocean. If Bab el-Mandeb becomes too dangerous, the oil may technically have bypassed Hormuz only to face another high-risk bottleneck farther down the route. That weakness is already visible in actual shipping data.
Saudi crude loadings from Yanbu fell to around 3 million barrels per day after July 20, compared with roughly 3.8 million barrels per day during April through June, as Houthi attacks and threats increased around the southern Red Sea. Some tankers have operated with their Automatic Identification System transponders switched off, while other cargoes have used the Suez Canal and Egypt’s SUMED system to reduce exposure to Bab el-Mandeb.
Shipping traffic has also shown how quickly confidence can disappear. On August 6, only one commodity vessel was recorded transiting Bab el-Mandeb after the Houthis claimed attacks on Saudi-linked oil tankers, compared with 20 vessels the previous day. Such numbers can understate traffic because some vessels may operate without transmitting AIS data, but the collapse still illustrates the sensitivity of shipowners to fresh threats.
For the bitumen market, this is where the story becomes more important than the refinery fire itself. There is currently no evidence that the August 9 Jazan incident has directly reduced Saudi bitumen production, and Jazan should not be presented as if it were primarily a road-bitumen production hub. Aramco describes the refinery as a full-conversion complex focused on products including gasoline, ultra-low-sulfur diesel, benzene and paraxylene, with heavy refinery streams integrated into its gasification system.
The East-West pipeline also transports crude oil, not finished bitumen. Therefore, the direct bitumen impact of attacks on the Saudi bypass system is different from the impact on crude exports. The real issue is shipping.
Bulk bitumen destined for East Africa, the Mediterranean or European markets depends on a specialized logistics chain. The product normally requires heated storage, heated loading systems and vessels capable of maintaining sufficiently high cargo temperatures during the voyage. The pool of suitable ships is much smaller than the global crude or conventional product tanker fleet.
When a region becomes more dangerous, a specialized shipowner has fewer replacement vessels and fewer opportunities to spread the risk across a large fleet.
That can make chartering availability as important as the nominal price of bitumen.
War-risk insurance in the Red Sea had already risen sharply before the August 9 attacks. By July 23, indicative premiums for southern Red Sea voyages had moved above 1% of vessel value, from around 0.3% before the latest Houthi escalation. For some Saudi-linked ships and voyages involving southern Saudi ports such as Jizan, quotes had reached as high as 3% of vessel value. Even a relatively small percentage increase can add hundreds of thousands of dollars to the cost of a voyage.
The insurance market then widened its designated high-risk zone. By July 30, the marine insurance sector had expanded the Red Sea high-risk area northward toward the Saudi coast near Jizan. At the same time, indicative war-risk premiums for ports farther north, including Jeddah and Yanbu, had jumped to about 1% from 0.25%, while southern Red Sea voyages were being quoted at roughly 1%–2% of vessel value.
The August 9 attacks give underwriters and shipowners another reason to keep those premiums elevated.The important question is not only whether a missile physically hits a commercial vessel. Insurance pricing is based on the probability of loss. Repeated strikes on refineries, ports, tankers and military positions can raise the perceived probability of an incident across the entire area.
That changes charter negotiations.A shipowner may demand higher freight before accepting a cargo. The owner may also require additional war-risk compensation, broader cancellation clauses, shorter exposure windows or stronger guarantees regarding the loading and discharge ports.
For bitumen, these costs can become commercially significant very quickly because cargoes are much smaller than crude-oil shipments.
A VLCC can spread a large additional insurance bill across roughly 2 million barrels of crude. A specialized bitumen carrier normally moves a far smaller cargo. That means a security-related cost increase can represent a larger dollar amount per ton of product.
This is especially relevant for East African markets. The Red Sea and Bab el-Mandeb provide an important route for petroleum products moving between the Middle East and ports such as Mombasa and Dar es Salaam. From there, material can move into inland markets including Kenya, Tanzania, Uganda, Rwanda and neighboring countries.
If shipowners become less willing to pass Bab el-Mandeb, suppliers have several choices, but none are cost-free.
They can wait for security conditions to improve. They can pay a higher risk premium. They can search for a different vessel. Or they can consider the much longer route around the Cape of Good Hope.
For Europe and North Africa, the calculation is different but still difficult. Cargoes already inside the Red Sea can move north toward Suez without passing Bab el-Mandeb again, but vessels approaching the Red Sea from the Indian Ocean face the southern chokepoint. Alternative routing can significantly increase sailing distance, fuel use, vessel time and therefore freight.
The result could be another widening gap between FOB bitumen prices and delivered prices.
A supplier may face pressure to lower its price at origin because buyers are reluctant to accept the logistics risk. But the same buyer may still receive a high delivered quotation because freight and insurance have increased.
That is a pattern the bitumen industry has already seen during the Hormuz disruption: weaker economics at the loading point do not necessarily translate into cheaper material at destination.
The Red Sea situation creates another problem for regional diversification.
When Hormuz became unreliable, Saudi Arabia’s East-West pipeline and Yanbu appeared to offer a strong alternative to the Gulf export route. Other producers have also been examining Mediterranean and Red Sea options. The logic was simple: move crude or heavy products overland, then place them on a vessel outside Hormuz.
But the advantage of an alternative route depends on the safety of the route that comes next.
If Bab el-Mandeb becomes highly restricted, Saudi Arabia can still move crude to Yanbu, but Asian-bound tankers face a difficult decision. They can accept the Red Sea risk or sail north through Suez and then take a much longer route to Asia. For some cargoes, either option can substantially increase transportation costs.
That does not make Yanbu useless. It remains a major strategic asset and still allows Saudi Arabia to avoid Hormuz entirely at the pipeline stage. But the attacks reduce the commercial advantage of the Red Sea bypass because the final maritime leg is no longer reliably low-risk.
The latest strikes also show that the threat is no longer limited to ships themselves.
In recent weeks, attacks have involved tankers, energy facilities and port infrastructure. On July 27, the Houthis said they had targeted sensitive Saudi crude-supply and transportation infrastructure connecting the east of the kingdom with Yanbu. Earlier attacks also affected Jazan and other Saudi Red Sea installations.
That broadens the risk from “Will my vessel be attacked?” to several additional questions: Will the loading terminal remain operational? Will storage be available? Will the refinery restart on schedule? Will the vessel be able to enter and leave safely? Will insurers maintain cover throughout the voyage?
Those are exactly the questions that influence bitumen chartering. The August 9 incidents should still be interpreted carefully. Mocha is damaged, but Bab el-Mandeb has not been confirmed closed. Jazan experienced a fire, but the latest incident has not been shown to remove another 400,000 barrels per day of refinery output because the refinery was already offline. And there is no confirmed direct shortage of Saudi bitumen caused by these attacks.
The stronger signal is logistical. Two of the Middle East’s most important maritime routes are now being treated as security risks at the same time. Hormuz remains heavily disrupted, while Houthi attacks have pushed insurance costs higher and reduced confidence around Bab el-Mandeb. Gulf oil exports were still around 40% below prewar levels in July, and Red Sea exports from Yanbu had already slowed before the latest strikes.
For the bitumen industry, the immediate indicators to watch are therefore not only refinery operating rates. War-risk premiums for Jizan, Jeddah and Yanbu will matter. So will the number of vessels actually transiting Bab el-Mandeb, the willingness of specialized tanker owners to accept Red Sea nominations, any further attacks on Saudi energy infrastructure, and whether ships begin choosing the Cape route more frequently.
Yanbu crude loadings will also provide a useful signal. If Saudi exports through the Red Sea recover despite the attacks, it would suggest that the market is learning to operate at a higher security cost. If loadings continue falling, it would indicate that the alternative to Hormuz is losing practical capacity even if the pipeline itself remains operational.
For bitumen buyers in Africa and Europe, the difference could eventually appear in freight quotations before it appears in physical supply.
That is the central implication of the August 9 attacks. The Jazan fire alone is not evidence of a new bitumen shortage, and damage at Mocha does not mean Bab el-Mandeb is closed. But taken together with the previous attacks on Saudi tankers, Yanbu-linked infrastructure and the rising insurance premiums already visible across the Red Sea, the incidents show that the Hormuz bypass is no longer a low-risk solution.
Saudi Arabia can move crude across the peninsula. It cannot move the Red Sea away from Yemen.
For the global bitumen trade, that means the risk increasingly lies not only in where the product is produced, but in whether a specialized vessel can reach it, insure the voyage and deliver it at a freight cost the buyer can still accept.
