“Additional capacity is rarely helpful for market pricing in our experience,” JP Morgan has said, as Aon prepares to bring a new reinsurance syndicate to Lloyd’s with capital from funds managed by Blackstone.
Announced earlier this month, Cortina syndicate 1956 is designed to give Blackstone-backed investors exposure to reinsurance business placed by Aon, while providing clients with a stable source of long-term capacity.
The vehicle will reportedly take a small, predefined share of the contracts Aon places, with clients receiving a dividend linked to Cortina’s participation. The launch marks the latest iteration of a model that has gained traction during previous soft market cycles, according to JP Morgan.
“We have seen market facilities gain traction in previous soft markets,” the firm observed. “In 2013, a deal with Aon and Berkshire Hathaway was agreed when the soft market conditions were just beginning.”
JP Morgan does not expect the latest capital deployment to have a significant immediate impact on competition, although it questioned whether it would support pricing.
“We do not see the new forms as capital as a huge near-term negative but unlikely to be helpful for pricing,” the firm added.
Global property catastrophe reinsurance pricing has fallen at record levels in 2026, following very strong results for reinsurers. JP Morgan noted the new capital entering the market was not substantial enough, on its own, to make the sector more competitive.
The largest reinsurers would remain important, as new capital would need to rely on established lead underwriters at other firms to set pricing, terms and conditions.
However, JP Morgan suggested that Cortina could pave the way for further capital deployment if the model proves successful.
“Once the concept has been proven, we are likely to see further capital deployed into the market,” the firm said.
JP Morgan also noted that higher interest rates during the previous soft market cycle had made alternative capital returns less attractive to asset allocators.
The investment environment has since changed, with capital backers able to use investment leverage of three to four times to target mid-teens returns despite relatively low underwriting margins.
JP Morgan does not expect the new facilities to displace the largest reinsurers in the near term.
“We do not see the capital replacing the larger players in the market anytime soon,” the firm concluded, while reiterating its concern over the potential pricing effect of additional capacity.
Other analysts have echoed these concerns. In a recent report, Evercore ISI highlighted that while structures such as Cortina have the potential to attract more disciplined capital than previous reinsurance start-ups, introducing additional capacity into a finite risk pool remains negative for reinsurers, with the potential to put further pressure on pricing.
