A secondary market for reinsurance
Reinsurance is one of the primary sources of capital supporting global underwriting. By absorbing volatility, it can increase underwriting capacity and reduce required equity and debt capital thereby improving a firm’s weighted average cost of capital (WACC). Yet despite its central role in the global risk transfer system, it remains structurally illiquid. Once placed, almost all reinsurance capital is held to maturity over annual contracts, with limited scope for adjustment.
In its new report, A secondary market for reinsurance, Howden Re examines the consequences of that illiquidity and articulates a framework for introducing structured secondary trading. By separating origination from ongoing ownership, as other mature capital markets have done, reinsurance could embed optionality into its contracts, improving capital efficiency and supporting more efficient pricing.


In credit markets, secondary trading transformed static exposures into dynamic balance-sheet assets. We see the same opportunity in reinsurance. A functioning secondary market would let participants actively manage risk through the cycle, releasing capital when returns compress and adding exposure when pricing improves
Reinsurance within the capital structure
Reinsurance behaves as contingent capital. By absorbing losses, it reduces earnings volatility and lowers the risk borne by equity and debt holders. As the report demonstrates, it can be analysed as a component of a firm’s weighted average cost of capital, operating as a third contingent financing layer.
However, unlike debt or equity, reinsurance does not typically benefit from an active secondary market. Capital must be committed ex ante and priced to reflect the inability to rebalance exposures mid-term. This irreversibility introduces an implicit financing friction and increases the effective cost of contingent capital.
Introducing secondary trading alters this dynamic. Drawing on a real options framework, the report explains that the ability to defer, expand, contract or exit a position as uncertainty resolves, has measurable economic value. In a hold to maturity market that option value is negligible. In a liquid market, it becomes material.
‘When reinsurance is treated as a third form of capital, the case for liquidity becomes obvious. Secondary trading turns static, hold-to-maturity contracts into flexible instruments with real option value. This, in turn, lowers the cost of capital for cedents while allowing reinsurers to allocate balance sheet capacity far more efficiently.’

Lessons from mature capital markets
The report draws parallels with the development of the unfunded loan and syndicated credit markets. In those initially illiquid markets, underwriting and distribution became distinct functions as secondary trading infrastructure developed.
Reinsurance today resembles an earlier stage of that evolution. Syndication exists, broker intermediation is central and counterparties are pre-approved. What is missing is the infrastructure required to support efficient post placement trading. The logical progression, the report argues, is to build liquidity on top of the broker led ecosystem rather than in place of it.
An all market solution
A successful secondary liquidity pool must deliver value to cedents, reinsurers and retrocessionaires alike.
Because reinsurers rarely achieve optimal portfolio composition at renewal, secondary trading would allow exposures to be rebalanced in line with internal capital models and evolving underwriting views. Cedents could trade risk off existing treaties during the coverage period rather than relying solely on incremental retrocession or direct and facultative (D&F) purchases.
Following seasonal events, collateralised retrocessionaires could reduce exposure and release collateral for tactical investing. Traditional reinsurers could increase participations selectively where marginal profitability is attractive. Over time, greater liquidity should support more efficient capital deployment and, consistent with corporate finance theory, lead to more efficient and ultimately lower pricing.
Brokerassist as enabling infrastructure
Realising a secondary market requires operational infrastructure. Howden is working with technology company Brokerassist to support transactions suited to this approach.
Brokerassist enables many-to-many interactions between cedents, reinsurers and retrocessionaires while preserving the broker-led allocation process. Participants can indicate the prices at which they wish to increase or reduce allocations, alongside associated capacity levels, generating structured supply and demand curves within an optimisation framework.
The platform does not impose a single prescriptive allocation. Instead, it produces a set of feasible outcomes that brokers evaluate and refine in line with client objectives, strategic relationships and qualitative considerations. This enhances transparency without disintermediating brokers or undermining existing governance and credit structures.
A deliberate evolution
The barriers to a secondary market are practical rather than conceptual. Introducing liquidity requires a deliberate, broker-led approach that aligns with the industry’s governance, credit and relationship structures.
If successfully implemented, a secondary market would enable carriers to allocate risk more dynamically, improve capital utilisation to support more efficient and ultimately, lower pricing.
Over time, this evolution would expand reinsurance’s role as a supplier of contingent capital while remaining consistent with the characteristics that underpin its stability and resilience.
