War Risk Insurance Stocks Back In Focus As Shipping Costs Rise

With trade rules being ripped up, shipping lanes disrupted and war risk premiums back in the headlines, the usually quiet world of marine and cargo insurance is suddenly on every risk manager’s radar. For investors, that shift can create fresh winners as well as new fault lines. This article walks through three stocks linked to this theme that appear well placed according to our screener and current news catalysts.

The stocks covered below are only a sample cut from this theme. The full screen surfaced 24 more companies with equally detailed war risk and marine cargo narratives that are not shown here. If you want to identify and analyze your own highest conviction ideas in this niche, head straight to the War-Risk and Marine Cargo Insurance Providers screener.

Hannover Rück (XTRA:HNR1)

Hannover Rück is a global reinsurer that sits right inside this war risk and marine cargo theme, with a large property and casualty book that includes marine, upstream energy and specialty covers that can be directly exposed when shipping routes and energy flows are disrupted. The group generated about €16.9b of revenue from Property & Casualty Reinsurance and €7.8b from Life and Health Reinsurance, so the specialty risks that feed off global trade sit within a broad, diversified engine. With a market cap of roughly €30.8b, Hannover Rück is a large, established player in this niche rather than a small specialist.

For investors watching higher war risk premiums and more expensive shipping insurance, Hannover Rück offers something more than a simple trade on headlines. Management highlights premium growth, disciplined underwriting and the use of advanced analytics to keep a tight handle on complex risks, while recent results indicate both profitability and resilience to geopolitical shocks so far. In this context, investors gain exposure to marine and energy reinsurance themes, a sizeable dividend and a large, diversified balance sheet, but with ongoing questions about competition, pricing pressure and how much room is left for earnings to keep improving from here.

Hannover Rück’s broad reinsurance engine can make war risk and marine volatility look like just one moving part, yet that scale can also hide key pressure points. See how the analysis report for Hannover Rück reframes the story around one crucial swing factor.

Clarkson (LSE:CKN)

Clarkson leans into the War Risk and Marine Cargo Insurance Providers theme from the shipping side, acting as a broker and adviser when shipowners and charterers need to rethink routes, cargo flows and financing as tariffs and conflict reshape global trade. Most of its revenue comes from Broking at about £564 million, with meaningful contributions from Support at roughly £75 million, Financial at £79 million and Research at £29 million. This combination gives investors exposure to chartering, port services and shipping data in one package. With a market cap of about £1.5 billion, Clarkson is a mid sized player that connects directly into the same shipping and risk conversations that insurers and reinsurers are pricing every day.

For investors watching how war risk premiums, tariffs and sanctions ripple through shipping, Clarkson offers a way to be paid for the extra complexity rather than only suffer it. The company sits at the centre of ship chartering and advisory work when routes shift, and recent half year 2026 results highlight solid revenue and earnings, helped by demand for chartering, financing and data. At the same time, an unstable dividend record, premium P/E and reliance on external funding mean the story is not without risk. The upcoming CFO and COO changes, with senior hires from BP’s shipping arm, could be an underappreciated twist in how Clarkson balances growth, capital discipline and exposure to marine risk.

Clarkson’s shipping earnings story and premium P/E can look straightforward, yet the real twist sits in how future trade routes and risk pricing reshape its broking and data income. The analyst forecasts for Clarkson lays out what that pivot could mean next.

James Fisher and Sons (LSE:FSJ)

James Fisher and Sons is a specialist marine services and engineering company that plugs into the war risk and marine cargo theme by helping shipowners, energy groups and defence customers manage complex offshore and subsea operations when shipping risk and insurance costs rise. Revenue is relatively balanced across Energy at about £158.9 million, Defence at £88.8 million and Maritime Transport at £147 million. This provides exposure to offshore wind, subsea services, submarine rescue and coastal shipping in one package. With a market cap of roughly £223 million, James Fisher and Sons is a mid sized way to access demand for marine risk management and support rather than insurance cover itself.

James Fisher and Sons provides a route into war risk exposed shipping without buying an insurer, through services that help keep offshore energy projects, subsea assets and military operations running when trade routes and insurance costs are under pressure. Management is working through a turnaround that aims to lift margins and return the business to sustained profitability, while changes in defence and energy security spending may affect its Defence and Energy order books. The company is currently loss making and relies on external borrowing, so any potential upside from a re rating depends heavily on execution and on how much upcoming results on 8 September 2026 show tangible progress rather than just stated plans.

James Fisher and Sons has a turnaround story that could be easy to underestimate, with Energy, Defence and Maritime all in play while the balance sheet still carries scars from past losses. The analyst forecasts for James Fisher and Sons shows how that mix might shift if margins really move, and where the pressure points could surprise you.
