The boarding of the tanker SUN shows why following maritime movement is no longer enough. Increasingly, analysts also need to establish whether the legal identity moving across the map is real.
Commercial shipping through the Strait of Hormuz remains suppressed as
operators adapt routing, loading and risk-management decisions.

Monitoring Focus:
Commercial transits, tanker availability, AIS behaviour, war-risk exposure,
alternative loading arrangements and operator decisions.
Current Picture
Commercial shipping through the Strait of Hormuz remains materially below
normal operating levels. Visible commodity-vessel movements have declined
significantly during the current security crisis, while some vessels have
reduced or interrupted AIS transmissions, complicating assessment of the
true volume of traffic.
The operating environment has also become increasingly adaptive. Regional
producers and shipping companies are using alternative loading,
transhipment and ship-to-ship arrangements outside the Strait where
possible, particularly around Fujairah and Sohar.
P&C assesses that the key question is no longer simply whether Hormuz
is physically open, but whether commercial operators consider routine
transit sufficiently safe, insurable and economically viable.

Why We Are Monitoring
Repeated vessel attacks and persistent uncertainty around Hormuz can
influence commercial behaviour even without a formal closure of the
Strait.
A sustained reduction in inbound tanker movements could become
particularly important. Gulf export capacity depends not only on outbound
loaded vessels, but on sufficient tanker tonnage entering the region,
calling at terminals and subsequently returning through Hormuz.
The monitoring requirement therefore extends beyond incident reporting.
P&C is watching for evidence that a short-term security shock is
becoming a more persistent commercial-access problem.
Indicators
01
Visible Commercial Transits
Track daily visible commodity-vessel movements against recent and
pre-crisis averages.
02
Inbound vs Outbound Tankers
Monitor whether inbound tanker activity is declining faster than
outbound movements.
03
AIS Suppression
Watch for increased use of intermittent, degraded or absent AIS
transmissions around Hormuz.
04
Fujairah & Sohar Activity
Track alternative loading, ship-to-ship transfers and cargo
movements outside the Strait.
05
War-Risk Insurance
Monitor changes in premiums, exclusions and insurer requirements
affecting Gulf voyages.
06
Operator Decisions
Watch for shipping-company suspensions, voyage delays or restrictions
on Gulf entry.
07
Further Vessel Attacks
Monitor additional kinetic incidents, particularly around Musandam
and inbound traffic lanes.
08
Alternative Export Patterns
Track greater use of pipelines, offshore transfers and non-Hormuz
loading arrangements.
ESCALATION TRIGGERS
P&C would consider the monitoring picture materially deteriorated if
one or more of the following occurs:
Visible commercial transits fall materially below current levels.
A major tanker, container or energy operator suspends Gulf entry.
War-risk insurance conditions tighten sharply or cover becomes unavailable.
A sustained fall in inbound tanker movements becomes visible.
Another merchant vessel is struck, seized or materially damaged.
Alternative loading outside Hormuz becomes a sustained operational pattern.
P&C ASSESSMENT
The Strait of Hormuz remains physically navigable, but commercial
operability is materially degraded.
The most important indicator is not simply the number of vessels crossing
the Strait on any given day. The more consequential question is whether
operators are changing behaviour in ways that become persistent.
Rising use of alternative loading arrangements, suppressed inbound tanker
traffic, increased AIS discretion and sustained war-risk pressure would
indicate that the disruption is evolving from a temporary security event
into a structural operational constraint.
If those indicators continue to deteriorate together, the impact could
extend beyond shipping security into tanker availability, regional
terminal operations, freight pricing and Gulf energy-export resilience.
What Would Change Our Assessment
IMPROVEMENT
Sustained recovery in vessel traffic, reduced attack activity and
stabilisation in insurance and operator behaviour.
DETERIORATION
Further attacks, sharp reductions in inbound tanker movements or
major operator suspensions.
STRUCTURAL SHIFT
Alternative export and loading arrangements becoming routine rather
than temporary crisis measures.
Assessment Confidence
HIGH confidence that commercial traffic remains
materially disrupted.
MODERATE confidence in precise transit-volume estimates
because AIS suppression and inconsistent vessel transmissions reduce
visibility.
MODERATE confidence that alternative loading and routing
arrangements will continue while security risk remains elevated.
