Operational Overview 

Maritime activity in and around the Strait of Hormuz has entered a new phase. The system is no longer defined by suppression of traffic, but by its selective reintroduction under an increasingly formalized Iranian control regime.

On March 26, seven non-Iranian vessels completed confirmed transits through the Strait, marking a further step in the scaling of the controlled passage system that has emerged over the past two weeks. These movements are not occurring through standard commercial lanes, but through a managed corridor along Iranian territorial waters, primarily north of Larak Island.

This reflects a clear shift in operational logic. Iran is no longer limiting movement outright, but actively shaping it. Approved vessels are allowed to transit based on cargo type and alignment, with Iranian energy exports prioritized outbound and essential goods such as food and agricultural cargo prioritized inbound.

At the same time, the broader maritime system is adapting structurally. Logistics networks, port operations, and freight markets are reorganizing around constrained access, rerouted flows, and elevated risk.

Strait of Hormuz Traffic and Controlled Transit

Transit through the Strait continued to scale on March 26, with seven confirmed crossings recorded, excluding Iranian vessels and incomplete passages.

This reinforces the pattern observed in recent days. Movement through Hormuz is no longer halted, but remains selective, controlled, and only partially visible. Transits are occurring outside standard international navigation routes, with vessels increasingly routed through Iranian-controlled waters and often operating under semi-dark conditions.

The growing number of crossings indicates that Iran’s managed transit system is now operational at scale. Approved cargoes are moving through the corridor, while standard commercial lanes remain effectively closed.

This system prioritizes outbound energy exports and inbound essential goods, reflecting a controlled throughput model rather than open maritime access.

Oman as the Primary Alternative Hub

Oman has emerged as the central workaround for regional maritime trade.

Its strategic position is unique. Salalah, Sohar, and Duqm are the only major ports in the region located outside both the Strait of Hormuz and the Bab el-Mandeb threat zones. As a result, they offer the only viable discharge points for Gulf-bound cargo that allow mainline vessels to avoid entering high-risk areas.

With Gulf ports effectively trapped and Red Sea routes exposed, Oman has become the default pivot point for cargo flows. This shift has been reinforced by the collapse of Fujairah as a bunkering hub, redirecting both cargo and fuel demand toward the Omani coast.

Iranian Strikes on Omani Ports

Despite Oman’s role as a neutral mediator, its infrastructure has been directly targeted.

Duqm was struck between March 1 and 3, followed by a strike on Salalah on March 11. The Salalah attack forced a full suspension of terminal operations for five days, while Duqm’s fuel storage was also hit and temporarily taken offline.

Following these incidents, the Joint War Committee reclassified all Omani waters as war-risk zones, extending insurance repricing across the entire coastline.

The targeting logic appears operational. As Salalah emerged as the primary exit point for rerouted cargo, Iranian strikes were directed at degrading that workaround.

Salalah Port Rerouting Signal

Salalah has become the clearest indicator of structural rerouting in the region.

It is the only major container hub in the western Indian Ocean located outside both primary threat zones, with established overland connections into Gulf markets. This allows cargo to be discharged safely and then transported inland to destinations such as the UAE, Saudi Arabia, Qatar, Kuwait, and Bahrain.

Destination-change data reflects the scale of this shift. Observations rose sharply from 55 the week of March 5 to 71 by the week of March 19, indicating sustained and growing rerouting activity.

Although the March 11 drone strike temporarily halted operations, the port resumed activity within five days and remains central to Gulf cargo diversion.

The cost impact is significant. Shanghai-to-Gulf freight rates rose 72% in a single week, while China-to-Salalah rates increased by 28% independently, confirming that demand is driven by rerouting rather than local consumption. 

Salalah is no longer functioning as a contingency option. It has become the primary transshipment hub for Gulf cargo under sustained disruption.

The Rerouting Mechanism

Rerouting has become a formalized logistics system.

Mainline vessels are now discharging cargo at alternative ports, including Salalah, Sohar, Duqm, Khor Fakkan, and Colombo. From there, cargo is transferred via feeder vessels or transported overland into the Gulf.

This model allows large vessels to avoid high-risk zones while shifting exposure to smaller vessels and trucking networks.

On March 12, this system was formalized through Dubai Customs Notice No. 04/2026, establishing a Green Corridor between Oman and the UAE. Cargo cleared in Oman is transported overland via Al Wajajah and enters the UAE through Hatta, with the system operating in both directions.

Qatar has also formalized its reliance on Oman, designating Sohar, Salalah, and Duqm as primary alternatives to Hamad Port.

What began as an improvised response is now a codified logistics framework.

Bunkering Vacuum and Oman’s Replacement Role

The collapse of Fujairah has created a structural gap in global bunkering.

As the world’s second-largest bunkering hub, Fujairah’s shutdown due to repeated drone strikes has forced vessels to seek alternative refueling points. Oman is the only viable option along the Asia–Europe routing corridor.

Salalah, Sohar, and Duqm are now absorbing displaced fuel demand across multiple facilities, reducing reliance on a single concentrated hub.

Windward data shows a significant increase in ship-to-ship bunkering activity in Omani waters. Between February 26 and March 5, nine bunkering tankers operating below three knots were observed, approximately 68% above predicted levels and marking an all-time high.

This reflects a rapid shift in fuel supply dynamics following Fujairah’s disruption.

Wet Cargo Market in Oman

Oman is also absorbing shifts in energy trade flows.

Over the past 12 months, wet cargo exports totaled approximately 597 million barrels, averaging 1.5 million barrels per day. Since the start of the conflict, volumes have remained relatively stable, but destination patterns are shifting.

China remains the largest importer, followed by South Africa. However, March data shows increased exports to Pakistan, the UAE, Taiwan, and China, with approximately 20% of volumes redirected away from previous destinations such as South Korea, South Africa, and Singapore.

This indicates that Oman is not only facilitating logistics rerouting but also absorbing changes in global energy distribution.

Container Pressure and Anchored Vessels in Omani Waters

Container activity in Omani waters has reached record levels.

Between March 5 and 12, 20 container vessels were anchored in Omani waters, approximately 62% above predicted levels and marking an all-time high.

This reflects growing pressure on port capacity, with congestion driven by rapid discharge cycles, sequencing delays, and accelerated cargo movement inland. Cargo is often being cleared and moved within one to two days, indicating high operational intensity.

This pressure is likely to extend downstream, with potential impacts on broader supply chains, including automotive logistics.

Military and Security Environment

Security conditions along the Omani coast are becoming more complex.

An Indian warship deployed to Omani waters on March 12 represents the only visible international patrol presence, alongside Omani and UAE maritime security vessels operating near the coastline.

At the same time, two key political signals emerged on March 26. Oman formalized its strategic partnership with the European Union, while a senior Houthi official signaled readiness to resume attacks in the Red Sea.

This combination increases Oman’s strategic importance while also raising its exposure. As the primary east–west logistics pivot, any escalation in Bab el-Mandeb would further concentrate pressure on Omani ports, freight systems, and regional energy flows.

Outlook

Transit through Hormuz is increasing, but only within a controlled Iranian system defined by selective access and managed routing. Standard commercial lanes remain effectively closed, while approved cargo moves through a northern corridor.

Oman has become the central logistics workaround, with its ports absorbing cargo, fuel demand, and rerouted flows at scale. This shift is now embedded in carrier operations, customs frameworks, and freight pricing.

At the same time, Iran has demonstrated a willingness to target Omani infrastructure despite its neutral status, reinforcing the fragility of this workaround.

Energy and trade flows continue, but under increasing constraint. Freight costs remain elevated, insurance conditions have tightened, and port systems are operating under sustained pressure.

The system is not stabilizing. It is reorganizing around controlled access, rerouted logistics, and persistent multi-theater risk.
