Insured losses arising from the collapse of the Francis Scott Key Bridge in Baltimore, struck by the Singapore-registered vessel Dali, are now projected to exceed $2.8bn, according to Howden Re. The revised estimate significantly exceeds earlier market expectations of approximately $1.5bn following the incident in March 2024.
Howden Re stated that the financial impact is expected to be borne largely by reinsurance and retrocession markets rather than primary insurers. The event is now assessed as the largest marine insurance loss on record, surpassing previous estimates linked to major maritime disasters.
A substantial portion of the revised loss figure—around $2.5bn—is associated with a settlement framework between the State of Maryland and insurer Chubb. Additional insured costs are attributed to pollution liabilities, wreck removal operations, and lost toll revenue arising from the closure of the bridge.
The incident has overtaken the previous benchmark for marine insurance losses, set by the Costa Concordia disaster in 2012, which generated insured losses of approximately $1.6bn.
Market analysis indicates that the financial consequences of the Baltimore collapse have become clearer only after extended legal proceedings, salvage activity, and reconstruction planning. The evolving nature of these processes has contributed to upward revisions in insured loss estimates over time.
While early market assessments suggested that the full $3bn reinsurance limit of the International Group of P&I Clubs could be reached, the final settlement structure did not rely on statutory shipowner liability caps. Instead, losses have been distributed across multiple layers of reinsurance protection.
Estimated Loss Breakdown
| Component | Estimated Value | Description |
|---|---|---|
| Settlement framework | ~$2.5bn | Agreement between State of Maryland and Chubb |
| Environmental liabilities | Included in total | Pollution-related costs |
| Wreck removal | Included in total | Recovery and clearing operations |
| Lost toll revenue | Included in total | Revenue loss during bridge closure |
| Total insured loss | >$2.8bn | Aggregate estimate (Howden Re) |
According to market participants, exposure is concentrated among major reinsurers and retrocession providers, where single large-scale events can represent a significant proportion of capital at risk. Nevertheless, the wider insurance sector is considered to have sufficient capacity to absorb the loss within diversified portfolios.
Marine insurance portfolios are typically underwritten alongside other large-scale risks, including natural catastrophe exposures, which can generate substantially higher aggregate losses. As such, while the Baltimore incident represents a landmark loss within marine insurance, it is being evaluated in the context of broader global reinsurance risk accumulation.
