Capital Markets Now a Reinsurance Resident
Laurent Rousseau of Marsh Re states capital markets are now permanent residents in reinsurance, not visitors, as alternative capital grows.

Capital markets are now a permanent resident of the reinsurance industry, according to Laurent Rousseau, CEO of Global Capital & Advisory, and Europe and IMEA at Marsh Re. He made the remarks ahead of the industry's annual meeting in Monte Carlo.
Rousseau said investors are right to allocate more capital to the sector. This alternative capital makes the industry more efficient, he argued. It matches capital to a market that has delivered extremely profitable returns to investors.
Projected Capital Growth
The backdrop is a projected rise in dedicated reinsurance capital to a record $705 billion by the end of 2026. This growth is expected across both traditional and alternative sources.
| Capital Type | Projected Year-End 2026 Capital (USD billions) |
|---|---|
| Traditional | 575 |
| Alternative | 130 |
Conditions for Sustainability
Despite the positive outlook, Rousseau stressed the need for honesty about the conditions required for these dynamics to persist. The capital markets are not without volatility, he noted.
Many investors are still learning about insurance-linked securities (ILS) in all their forms. Rousseau explained that for this market to be sustainable, investors must understand the true nature of insurance and reinsurance risk. They need to grasp the very nature of claims development and adjustment.
Investors so far have bought into the return. They now need to buy into the risk. Understanding that operating in the reinsurance industry commands responsibility is key, said Rousseau.
Financial markets are volatile by nature. Rousseau emphasised that it will be the challenging years that truly test investor conviction.
A Long-Term Trend
Rousseau was clear about the overall direction. He stated that this has been a long-term trend, and has not yet found its equilibrium point.
He concluded that the capital markets are no longer a visitor to the industry; they are now a resident. he believes reinsurance companies that understand how to partner with the capital markets will gain a durable competitive advantage.
Why Cedents Embrace Alternative Capital
Rousseau outlined three key reasons why more insurance companies (cedents) are embracing alternative capital from the ILS universe. It brings them choice in both capacity and terms.
First, the source of capacity is different. Alternative capital responds to different dynamics than traditional reinsurers. Second, more supply means better terms. There is competition on the terms. Third, they operate in a very different way.
He described alternative capital as a follow capacity, not looking to lead a placement. He compared this to the primary insurance market's bifurcation between leaders and followers.
Rousseau said this trend is coming to the reinsurance world through capital markets. Alternative sources of capital provide this kind of follow capacity, and they can do it in size. Some of these funds are huge, he noted, capable of taking a 20% share across all placements. By doing so, they are very cost effective.
