Full Capacity: Reinsurers rev up with casualty sidecars

January 31 2026 by

Welcome to Full Capacity, a weekly briefing on all the most important developments of the past week with a personal take on the news from our editor-in-chief, Mithun Varkey, delivered to your inbox every Saturday.   

IAN exclusive. Howden Specialty has appointed Hugo Thornhill as its head of renewable energy for Asia Pacific. Thornhill will relocate from London to Singapore to build out the broker’s renewables platform and deepen local capability. 

M&A brief. Australian broker AUB Group will acquire 95.9% of UK insurance broking and MGA platform Prestige for US$299 million. The broker also completed a US$278 million share sale to finance its acquisition. 

Nat cat update. The Insurance Council of Australia expects insured losses from the Victoria bushfires to exceed US$140 million as claims rise. Since January 7, insurers have received over 3,123 claims related to the bushfires. 

New market. European reinsurer VIG Re will establish an office in Singapore having appointed Marc Haushofer as APAC managing director. Haushofer will be responsible for VIG Re’s existing business in Japan, South Korea and Taiwan, while also seeking to drive the reinsurer’s pan-Asian expansion 

Clearing space. As of 2026, there are estimated to be over 100 million pieces of space junk, from large trackable pieces such as defunct satellites and spent rocket parts, to tiny fragments, raising the risk of Kessler Syndrome, where the density of space junk in low Earth orbit becomes so high that collisions between objects cause a cascade effect, rendering orbit unusable. 

Michael Mainelli, the former lord mayor of the City of London, said that tackling the issue of space debris is the critical issue for the century.  

“Our use of space is already unsustainable. It hasn’t got to the point where we can’t do it, but it is already unsustainable,” he said. 

This is a global problem, and the solution will need to be global and syndicated across different players and insurers have a key role to play. 

Shifting gear  

The insurance-linked securities market has been defined by its focus short-tail lines. Property cat bonds, with their well modelled, one-year risks and liquidity appeal, dominated the space.  

The more complex, long-tail world of casualty risk remained largely the domain of traditional reinsurance balance sheets.  

However, the frontier is shifting with the emergence of the casualty sidecars. 

Casualty sidecars were a hot topic of discussion last year and since then we have seen a few vehicles come to market – most notably, QBE Re’s debut George Street Re sidecar launched last month, a fully collateralised quota share reinsurance transaction exceeding US$550 million. It joins the likes of Ascot’s Wayfare Re and Enstar’s Scaur Hill Re, among others. 

The expansion into investor-backed casualty vehicles signal that this is more than a passing experiment. No surprise, then, that brokers are also leaning into this momentum.  

On Thursday, Guy Carpenter CEO Dean Klisura, speaking to analysts as part of a Marsh earnings call, highlighted the growth opportunity in the casualty market and casualty sidecars. 

“Billions of dollars of new capital is flowing into the market for the creation of casualty sidecars. We’re right in the middle of that”, he noted. 

“You think about casualty sidecars, third-party capital, everything happening in the casualty world, we’re seeing strong growth in our casualty portfolio 1.1. 

“This is a source of new business growth and opportunities for growth that maybe didn’t even exist a year ago”, added Klisura addressing questions around organic growth opportunities in the face of a softening rate environment, especially property cat. 

For cedents, meanwhile, sidecars are becoming a financial tool to enhance underwriting capacity, diversify exposure, and free up regulatory capital in an environment where balance sheet agility matters as much as risk selection. Also, for MGAs, sidecars can become a reliable source of capacity while allowing them to retain a share of their business. 

Investors who shied away from casualty’s five-to-six-year tail now see an opportunity.  

In essence, the duration mismatch that once deterred alternative capital is flipping into an asset.  

“The investor appetite for longer duration exposures is a game changer,” noted Gallagher Re’s Andrew Newman in a briefing last year.  

Aon reinsurance solutions also noted that the recent investor interest in these transactions is due to higher interest rates and the growth in US private credit platforms. The broker expects more of these transactions to be executed in 2026. 

Unlike their property cat counterparts, where the focus is almost exclusively on underwriting results over a short period, these long-tail vehicles treat the investment performance of the collateral account not as a secondary detail, but as a core pillar of the financial model. 

Institutional investors now get to partner with reinsurers to capture underwriting returns and investment income, which traditional reinsurance has guarded closely for decades.  

For the sophisticated capital entering this space, strong underwriting is the foundation, but the power of investment returns is what truly completes the equation.
