As continuing international conflicts create fast-changing risks for vessels, cargo and crews worldwide, discover why responsive marine war insurance and an agile Lloyd’s broker matter more than ever.
For vessel owners and operators – and for brokers and insurers arranging marine cover – geopolitical risk is no longer confined to one region or one shipping route. Conflict and heightened tensions are affecting maritime activity around the Strait of Hormuz, Red Sea, Black Sea and elsewhere – sometimes simultaneously. When conditions can change within hours, you need more than insurance capacity. You need a marine insurance partner that can respond just as quickly. As an independent Lloyd’s broker, Costero Brokers combines specialist market access with agile marine broking, hands-on support and dedicated claims expertise.
A fast-changing risk map for global shipping
Recent events illustrate just how quickly the operating environment can shift, leading to rapid changes in war-risk pricing and underwriting appetite:

- War-risk premiums for southern Red Sea voyages rose sharply following renewed attacks. (Source: Reuters)
- Meanwhile in the Black Sea, further attacks subsequently pushed war insurance costs for some port calls significantly higher. (Source: Reuters)
Individual rates will continue to change, but the broader lesson is more enduring: yesterday’s assessment of a voyage may not reflect tomorrow’s risk.
This creates a difficult environment for vessel owners and operators – and the brokers and insurers that serve them. A ship may be waiting for conditions to improve before leaving a region. Another may need to enter a higher-risk area at short notice to fulfil a commercial commitment. A route that appears viable in the morning can look very different by evening.
Marine insurance therefore has to keep pace with operational reality.
Why hull war cover is increasingly in focus
Cargo war insurance remains important, but recent events have put the physical vessel itself – and the people aboard it – firmly at the centre of the risk.
Marine war insurance can provide protection against specified war, terrorism, piracy and related perils affecting vessels and cargo, subject always to the wording, exclusions and conditions of the relevant policy. The London market’s Joint War Committee also issues its Listed Areas, identifying regions deemed to present heightened risks, where vessels may require additional war-risk cover.

Depending on the circumstances, your wider marine insurance response may need to consider not only cargo but also:
- Hull & Machinery and Hull War exposures.
- Protection and indemnity (P&I) considerations.
- Loss of hire.
- Liabilities and additional operating costs.
- Crew safety, repatriation and welfare.
- Claims coordination following an incident.
The key is not simply having a policy in place. It is having the right protection for the voyage, vessel and circumstances – and being able to adapt that protection when circumstances change.
When circumstances change, your Lloyd’s broker needs to move quickly
In a relatively stable market, it may be possible to approach marine insurance as a conventional placement and renewal process. War risk can be very different.
Market appetite can change quickly after an incident. Underwriters may reassess particular routes, ports, vessel characteristics or trading patterns. Capacity that was available yesterday may become more restricted, while another market may offer an alternative approach.
That means your Lloyd’s broker needs to be close to both you and the underwriting market.
For Costero, agility means being able to:
- Understand what you need and why you need it.
- Engage quickly with specialist marine war underwriters.
- Navigate changing underwriting appetite and capacity.
- Seek practical solutions for unusual or urgent voyages.
- Keep you informed as conditions and options evolve.
- Remain closely involved if an incident turns into a claim.
As an independent Lloyd’s broker, Costero has close relationships with underwriters across the London market, and a nimble decision-making structure. There are fewer layers between your problem and the people working to solve it.
Claims support is not an afterthought
The real value of marine insurance becomes particularly clear when something has gone wrong.
A serious marine war incident can involve far more than damage to the vessel. There may be surveyors, correspondents, underwriters, P&I interests, local authorities and other parties to coordinate. Crew may need medical assistance or repatriation. Owners and operators need clear information while simultaneously dealing with the operational consequences of the incident.
Costero’s Marine & Cargo division brings together comprehensive marine broking, strong relationships with marine underwriters, and specialist marine claims expertise. Our dedicated claims team has experience across Hull & Machinery, Loss of Hire, Cargo and P&I claims, including areas such as crew repatriation and personal accident.
That joined-up approach means claims considerations are part of the service rather than something handed off after placement.
Never losing sight of the people on board
War risk can easily be discussed in terms of premiums, vessel values, capacity and freight rates. But behind every maritime voyage is a crew.
The International Maritime Organization (IMO) has repeatedly highlighted the humanitarian impact of conflict on seafarers. During recent disruption around the Strait of Hormuz, it reported that around 20,000 seafarers, as well as port workers and offshore crews, were affected in the region, while an international evacuation framework was established to help vessels and crews leave safely.

That human dimension is always a priority. At Costero, we take a holistic view of marine risk. Protecting the hull and cargo is fundamental, but a broker’s role does not suddenly become purely transactional when an incident occurs. It means being there for owners and operators, helping coordinate the insurance response and remembering that the consequences may also be life-changing for crew members and their families.
Marine war risk requires a fast-responding Lloyd’s broker
Nobody can predict precisely where the next maritime flashpoint will emerge or how quickly an existing situation will change.
You can, however, make sure your insurance arrangements – and the people supporting them – are capable of responding quickly.
With specialist marine expertise, access to Lloyd’s and international markets, an independent and agile approach and dedicated marine claims support, Costero Brokers can help you navigate increasingly complex marine war risks from placement through to claims.
