The vast majority of the $2.8 billion will be absorbed by the reinsurance and retrocession markets. While some market participants initially anticipated the full $3 billion limit of the International Group’s reinsurance tower could be called upon, statutory limitations on shipowner liability did not ultimately constrain the settlement. Most original carriers will have reinsurance in place, and deterioration flows to further layers, says Howden Re.
When the container vessel Dali struck the Francis Scott Key Bridge in Baltimore in March 2024, early market reserves were placed at $1.5 billion. This figure became the working assumption for much of the marine and reinsurance market through 2024 and into 2025, shaping expectations at the 1.1.26 renewals.
Since then, legal, salvage and reconstruction costs have continued to evolve however the ultimate scale of the loss has now become clearer. Recent market disclosures now point to a total insured loss exceeding $2.8bn, reflecting a broader range of liabilities than initially anticipated, said Howden Re.
At this level, the Baltimore Bridge would rank as the largest single marine insurance loss ever recorded surpassing the circa $1.6bn insured loss from the Costa Concordia grounding in 2012. That previous incident had always been regarded as the sector’s previous benchmark event.
From $1.5 billion to $2.8 billion
The increase in the Baltimore bridge loss surprised much of the market. As Hugo Chelton, Managing Director at Howden Re, explains, the scale and speed of the reassessment caught many off guard.
“The announcement came late on a Friday,” Chelton notes. “By Monday morning it had gained real momentum. A $1.3 billion deterioration would be a major loss event in its own right – let alone when layered on top of what was already one of the largest marine losses the market.”
The principal driver of the increase is the cost of replacing the Francis Scott Key Bridge. The settlement framework between the State of Maryland and Chubb, who insured the bridge, accounts for approximately $2.5 billion of the overall loss, with pollution liabilities, wreck removal, and lost toll revenues contributing to the balance.
Central to the settlement is the role of the International Group of P&I Clubs, the collective body representing the 13 mutual clubs that collectively insure these types of marine liability risks. Individual clubs mutualise large claims through the Group’s pooling mechanism and a significant excess‑of‑loss reinsurance programme, enabling them to respond to catastrophic losses of this scale. The size and importance of the International Group’s reinsurance placements mean that outcomes such as Baltimore inevitably have implications well beyond the primary market.
Where does the loss land?
The vast majority of the $2.8 billion will be absorbed by the reinsurance and retrocession markets. While some market participants initially anticipated the full $3 billion limit of the International Group’s reinsurance tower could be called upon, statutory limitations on shipowner liability did not ultimately constrain the settlement. Most original carriers will have reinsurance in place, and deterioration flows to further layers.
“As the loss grows, it becomes increasingly concentrated,” Chelton says. “The deepest exposure lies with the large reinsurers and the retro market. For some participants, relative to their own capital base, this will represent a very significant single loss.”
This concentration effect mirrors market expectations expressed since 2024, which consistently identified the Baltimore incident as a potential record P&I and marine reinsurance loss, notwithstanding ongoing legal and liability uncertainties.
The market impact
Despite its scale, the Baltimore loss lands in a market that is already managing much larger aggregate risk. Marine, energy and terrorism portfolios sit alongside peak natural catastrophe exposures, particularly U.S. windstorm.
“The same carriers writing marine liability are also exposed to hurricanes,” Chelton notes. “In that context, a truly severe event is a $100 billion nat cat. A $2.8 billion marine loss is material for the class, but it has to be viewed within the wider portfolio decisions these carriers are making.”
Marine liability insurance and reinsurance will almost certainly see rates increase, and the aviation leasing loss settlements across many of the same carriers compound the pressure – not to mention the mounting losses arising from the Middle East conflict.
“Taken together, the cumulative effect is meaningful,” Chelton says. “Something has to give. Marine liability rates will rise. Whether that translates into a broader market correction is less clear.”
What comes next
The key counterweight remains capital. Across marine, energy and terror, capacity continues to exceed demand, with multiple sources estimating available limit at several times what is technically required for many large energy and infrastructure risks.
At the April 2026 renewals, pricing softened by as much as 15–20% in parts of the market, despite ongoing loss activity, as new entrants absorbed known exposures with little adjustment. Loss-affected carriers have reassessed their appetite, but fresh capital has continued to enter the market, maintaining competitive pressure on pricing and keeping the balance of negotiating power firmly with buyers.
“The market is navigating a complex set of signals,” Chelton notes. “Losses of this scale do shift thinking over time, and we are seeing the early conditions for that. The question for clients is how to position ahead of that turn, rather than react to it.”
