A voyage across the Indian Ocean can pass through several different risk environments, from piracy exposure in the Somali Basin to missile threats near Bab-el-Mandeb, heightened state activity around Hormuz and congestion approaching Malacca.
Describing the whole region as high risk may be directionally correct, but it does little to support a real decision. An operator needs to know where the threat changes along the route; an insurer needs to understand where exposure concentrates; and a trader or supply-chain team needs to see which part of the passage is most vulnerable to delay.
The Indian Ocean is connected by trade, but it is not defined by one threat. The assessment needs to follow the waters, vessel and transit window in question.
One Voyage Can Cross Several Threats
The Indian Ocean connects energy producers in the Gulf, manufacturing centres in Asia and markets in Europe, with much of that trade passing through a small number of chokepoints. Hormuz carries energy exports out of the Gulf, Bab-el-Mandeb connects the ocean with the Red Sea and Suez, and Malacca links the Indian and Pacific Oceans.
The US Energy Information Administration identifies Hormuz and Malacca as the world's two most important oil-transit chokepoints by volume. Disruption around Bab-el-Mandeb has also repeatedly diverted vessels around the Cape of Good Hope. US Energy Information Administration
These passages concentrate trade without concentrating the same threat. Hormuz may be shaped by state activity, electronic interference and regional conflict; Bab-el-Mandeb can bring missile, drone and piracy exposure; the Somali Basin presents danger far beyond the coast; and Malacca combines congestion with a different pattern of robbery and regional security activity.
A single regional label conceals those differences and can leave the people making the decision unclear about which part of the route requires attention.
Piracy Has Moved Back Offshore
International patrols, vessel protection and industry measures sharply reduced Somali piracy after the crisis of the early 2010s, but they did not remove the underlying capability. Incidents reported during 2025 showed that Somali pirate groups could still operate far from shore, while the International Maritime Bureau warned that sustained naval presence remained important to preventing a wider resurgence.

This matters because older passage plans can still treat piracy as a predominantly coastal threat. Pirate groups can use larger vessels to extend their reach, while weather and sea conditions change where small craft can operate. The assessment therefore needs to compare current capability and recent activity with the intended route rather than relying on distance from the Somali coast or a fixed boundary alone.
Naval Coverage Is Not a Shield
The Indian Ocean has significant naval and information-sharing coverage. The Indian Navy has taken a prominent role in responding to piracy and assisting merchant shipping, while other national and multinational forces operate across the Gulf of Aden, western Indian Ocean and adjoining waters.

That presence can improve awareness, coordination and response, but it does not create continuous protection across the ocean. A warship may still be hours away when an approach begins, surveillance is stronger in some corridors than others and different reporting centres cover different parts of a voyage.
Naval presence should therefore inform the assessment rather than replace it. Customers still need to understand where coverage is strongest, where it thins and what that means for the planned leg.
More Warships Can Bring More Complexity
Naval activity in the Indian Ocean is not limited to counter-piracy. India, China, the United States, France and other states maintain military interests and partnerships across the region, supported by ports, logistics arrangements, facilities and maritime surveillance.
For most commercial voyages, that competition remains in the background. It becomes relevant when exercises, military movements or political tension overlap with a chokepoint, port approach or intended route. More surveillance may improve awareness, while greater military activity can also create reporting, navigation and misidentification concerns.
The commercial question is not which state holds the stronger regional position, but where state activity changes the conditions around the voyage.
Know Where the Risk Changes Along the Route
A vessel travelling between the Gulf and East Asia may cross several distinct threat areas before reaching its destination. Operators may need to understand whether conditions change between individual legs, while insurers need to see where exposure is greatest and whether it falls inside a listed or specially rated area.
Charterers and traders may be concerned with delay, deviation and route reliability. Supply-chain teams may need to know where disruption could affect arrival times, inventory or production. Those decisions cannot be supported by treating the Indian Ocean as one undifferentiated region.
Depending on the voyage, the assessment may need to consider recent incidents along the track, offshore pirate capability, missile or state activity near chokepoints, electronic interference, naval presence, weather and applicable insurance or reporting requirements. What matters is the combination that applies to the vessel and route under consideration.
Follow the Route, Not the Regional Label
Verihelm examines a voyage leg by leg, bringing the route together with relevant incidents, changing threat areas and known requirements. This allows customers to see where risk changes instead of receiving one label for the whole Indian Ocean.
Dryad Global's intelligence team applies judgement where threats overlap, reporting is unclear or conditions have changed since an earlier assessment. The completed assessment passes through internal quality control and carries a visible approval status.
The result is not a declaration that the Indian Ocean is safe or unsafe. It is a clearer view of what the planned route may involve, where exposure changes and which parts of the passage need closer attention before the available choices narrow.
