One week after the ceasefire was announced, the maritime system has not returned to open navigation. Instead, the ceasefire has introduced a more complex operating environment, with continued vessel movement but no consistent framework for access or navigation.
According to analysis by Windward, in the immediate aftermath of the announcement, transits through the Strait of Hormuz continued, but under the same IRGC-controlled structure that had been in place since mid-March. Routing remained limited to alternative corridors through or alongside Iranian territorial waters, prior approval was still required, and vessels were explicitly warned that unauthorized passage could be targeted.
As the week progressed, it became clear that this was not a reopening, but a supervised pause. Transit conditions remained undefined, proposals for tolls and inspection requirements began to emerge, and no agreed legal or diplomatic framework was established.
At the same time, insurance constraints, unresolved enforcement conditions and the continued absence of mainstream operators indicated that the market did not view the ceasefire as a return to normal commercial operations.
By the second half of the week, the operating picture shifted further. US mine-clearance operations began inside the Strait, followed by a blockade targeting traffic linked to Iranian ports. The result was a two-layer environment: Iranian control continued to shape routing and access, while US enforcement increasingly influenced vessel behaviour.
The first week of the ceasefire therefore did not produce normalization.
Instead, it created a more complex maritime regime in which access remained controlled, movement continued selectively and trade flows stayed constrained even as enforcement expanded. The central trend remains that the Strait of Hormuz is active, but not open.
Gulf trade has adapted instead of waiting
While transit through Hormuz remained constrained, regional trade flows continued to adapt through alternative networks.
By this point, the diversion architecture built during the conflict is no longer a temporary workaround. It is a functioning logistics system. Direct calls into in-Gulf ports such as Jebel Ali, Dammam, and Hamad have been replaced by a five-node structure centered on Salalah, Sohar, Khor Fakkan, Fujairah, and Jebel Ali.
Salalah has become the primary Gulf land-bridge hub. It recorded 26 port-of-destination changes during the week, below the March peak but still far above pre-war norms, and 91 transshipment-changed cases, indicating large-scale rewiring of onward cargo connections.
Sohar has stabilized as the secondary land-bridge hub. Its 48 destination-change cases, roughly three times the pre-war baseline, suggest that diverted cargo has settled into a higher steady state. The absence of major delay or rollover spikes indicates that Sohar is handling its elevated role within capacity.
Khor Fakkan has become the UAE’s principal east coast intake point. With 85 destination changes in a single week, it is clearly functioning as a preferred discharge point for UAE-bound cargo that would previously have called Jebel Ali directly. But the April 5 projectile incident introduced a new variable. What had been a mainly operational and commercial calculation may now also include security exposure.
Fujairah is functioning as an overflow point under strain. The terminal recorded 6 rollovers and 10 delay cases during the week, while 86 destination changes show that carriers are increasingly terminating voyages there despite the resulting friction.
This reflects a shortage of viable alternatives, compounded by Fujairah’s already weakened bunkering role, following earlier drone strikes and force majeure conditions. The port is now operating under dual strain as both an impaired energy hub and an emergency container gateway, functioning as a safety valve rather than a stable long-term solution.
Jebel Ali remains central, but no longer as an ocean-side gateway. With 18 destination-change events during the week, it is increasingly serving as the inland redistribution endpoint for cargo arriving via upstream diversion nodes.
The U.S. added a second layer of control
The most significant structural change during the ceasefire week came from the U.S. side. What had initially been an Iranian-controlled access regime evolved into a dual-control environment following the start of U.S. mine-clearance operations and a subsequent blockade targeting traffic entering and exiting Iranian ports. This shift effectively transformed the Strait from a controlled chokepoint into a contested maritime space.
On April 11, U.S. guided-missile destroyers entered the Arabian Gulf to begin mine-clearance operations, with leadership later signalling potential interdiction and broader enforcement measures. By April 13, the blockade was formally in effect. It applied regardless of vessel nationality where movements were linked to Iranian ports, while transit through the Strait itself remained available to other vessels.
Rather than immediately halting traffic, these measures introduced a second layer of risk and uncertainty. Vessels were no longer responding solely to Iranian access restrictions but also to the possibility of U.S. interdiction actions.
Early effects emerged quickly. Sanctioned vessels altered course shortly before or around the enforcement deadline, while others resumed transit after delays, switched off tracking systems after passage, or attempted to use Iranian coastal routing to reduce exposure.
Overall, the operating environment shifted from a single controlled access regime to overlapping control systems, where enforcement pressures, evasive behaviour, and selective continuation occurred simultaneously.
