Asharp decline in tanker transits through the Strait of Hormuz and rising floating storage in the Gulf signal a shift toward risk-managed energy transport rather than normal market operations. Recent AIS data now indicates that commercial tanker traffic has effectively reached a near-standstill, with most vessels remaining anchored in the Gulf while operators assess security and insurance risks. Current indicators, including waypoint activity and vessel transit patterns, provide the basis for the disruption scenarios examined below.

Scenario Matrix
Scenario 1: De facto restriction of transit with rising floating storage

Probability: very high ( already developing)

The most immediate development appears to be a near-standstill in commercial tanker movements rather than a complete halt in traffic. Shipowners and charterers are assessing operational risks more carefully, and some departures are being delayed until freight economics justify the voyage.

Floating storage is becoming part of this adjustment. Tankers that would normally depart shortly after loading are, in some cases, remaining offshore while operators evaluate routing options and market conditions. Several vessels have already been damaged or threatened by drone and missile activity in the region, reinforcing shipowners’ reluctance to transit the strait.

Navigation through the corridor remains open, but activity may continue at reduced levels as shipping companies adapt to the prevailing security and insurance environment. At this stage, the situation reflects a commercial response to uncertainty rather than any formal restriction on transit.

‍Scenario 2: A two-route export structure

Probability: high

If the disruption persists, producers increasingly rely on a combination of pipeline exports and selective maritime shipments.

Pipeline infrastructure that bypasses the strait gains strategic importance, particularly in Saudi Arabia and the United Arab Emirates, where crude can reach ports outside the narrow passage. These routes provide partial relief but cannot handle the full volume normally exported from the Gulf.

As a result, some tanker movements continνue, although typically under tighter scheduling and higher risk premiums.

Scenario 3: Security-led stabilization of tanker movements

Probability: medium–high

If the slowdown begins to affect supply flows, maritime security operations in the region could expand. The United States Navy already maintains a significant presence in the Gulf and can monitor tanker traffic and support safe navigation if required.

Such measures are typically intended to reinforce confidence in commercial shipping. They may include increased patrol activity, coordination with maritime authorities, and cooperation with industry stakeholders to ensure vessels can transit safely. Policy discussions have already begun around naval escort missions and temporary insurance backstops designed to restore confidence among shipowners.

In practical terms, this could allow tanker movements to resume gradually, although under conditions where maritime security plays a more visible role in supporting the continuity of trade routes.

Scenario 4: Market shock and temporary pricing power

Probability: high

The current disruption to tanker movements in the Gulf is already being reflected in oil market pricing, with AIS tracking showing virtually no commercial tanker transits during several recent observation periods, indicating that shipowners are avoiding the corridor despite the absence of an official closure.

A useful historical comparison can be found in the tanker attacks of the 1980s, when disruptions to Gulf shipping contributed to sharp swings in freight markets. At the time, key Middle East export routes to Asia, including Japan, were closely watched indicators of tanker market conditions, and earnings could spike sharply as shipowners avoided higher-risk voyages and war-risk premiums increased.

Today, AIS data provides near-real-time visibility into tanker movements and can quickly indicate when commercial traffic through critical routes is slowing or changing patterns, although coverage is not always complete.

Scenario 5: Quiet operational coordination

Probability: medium–high

During maritime disruptions, it is common to see quiet coordination among exporters, shipping companies, insurers, and governments. This coordination usually focuses on maintaining trade rather than announcing formal agreements.

Producers such as Saudi Arabia and the United Arab Emirates have a strong incentive to keep exports flowing, while maritime powers like the United States provide security support.

Scenario 6: China’s potential diplomatic involvement

Probability: medium

Another factor increasingly shaping the situation is the role of China. As the largest buyer of Gulf crude, China has a strong interest in preventing prolonged disruption.

Rather than deploying military power in the region, Beijing is more likely to act through diplomacy and economic engagement. That could include discussions with producers, consultations with importers such as India, or mediation efforts aimed at keeping energy flows stable. So far, the evidence points to diplomatic influence rather than a formal coalition.

Scenario 7: Expansion of the maritime crisis

Probability: medium

The most serious escalation scenario would involve sustained disruption in the Gulf combined with instability spreading beyond the region into the Red Sea corridor. Instability linked to attacks by the Houthis has already increased security risks in the Bab el-Mandeb Strait, one of the world’s most critical maritime chokepoints connecting the Red Sea and the Gulf of Aden. While the strait remains open, attacks on commercial vessels and the resulting security operations have already disrupted traffic and caused many ships to reroute away from the Suez Canal corridor.

A further escalation, such as sustained attacks, mining of shipping lanes, or broader regional instability, could significantly affect transit through Bab el-Mandeb. In such a case, the disruption would extend beyond a single corridor and affect multiple maritime routes linking the Middle East, Europe, and Asia. This would force more vessels to divert around the Cape of Good Hope, increasing transit times, costs, and pressure on global supply chains.

Scenario 8: Disruption to Bunker Fuel Supply in the Arabian Gulf

Probability: Low–Medium

Escalating regional tensions could affect marine fuel supply infrastructure in the Arabian Gulf. Recent incidents have already highlighted the vulnerability of key bunkering hubs. A fire at Fujairah disrupted bunker operations after debris from an intercepted drone caused a blaze in the port’s oil industry zone, while a separate drone strike damaged a fuel storage tank at Duqm Port. If tanker traffic through Hormuz remains constrained, bunker demand patterns could shift further toward Asian hubs as vessels reroute or delay departures from Gulf ports.
These disruptions have begun to influence marine fuel markets, prompting some ship operators to seek alternative bunkering locations. Early signals indicate that part of this demand is shifting away from Gulf hubs. In Europe, the Northwest European bunkering region centred on Rotterdam, Antwerp, and Amsterdam has experienced tighter supply conditions and higher fuel premiums, while Mediterranean ports such as Gibraltar have also seen increased activity.

However, the most significant short-term demand shift has occurred in Asia. Major bunkering hubs, including Singapore, Colombo, and ports in India, have seen increased demand as vessels adjust fueling strategies while rerouting around higher-risk areas.

If regional tensions escalate further and disruptions to port infrastructure persist, bunker fuel availability in Gulf ports could become increasingly constrained, accelerating the redistribution of refueling demand toward European and Asian hubs while increasing fuel price volatility and operational costs for global shipping.

Overall Reading of the Situation

The situation remains highly uncertain, and it is difficult to determine which of the above scenarios may unfold next. Several of them remain possible under the current unstable security and geopolitical conditions.

At this stage, the most critical issues are the ability to maintain safe passage for vessels, the exposure of the marine insurance market, and the role that both China and the United States may play in securing shipping routes. Even if insurance coverage remains available and naval protection helps keep routes open, this does not mean that the conflict itself will stabilize quickly.

In the near term, energy transport may increasingly rely on a combination of maritime shipments and pipeline exports. Saudi Arabia’s pipeline network could help maintain exports while naval forces, particularly from the United States, continue to protect key sea lanes.

At the same time, regional diplomacy could influence how the situation develops. If Oman increases pressure and builds support among other regional actors, it could help create conditions for de-escalation and potentially shorten the duration of the current disruption.
