While White Mountains elected not to invest capital into the Outrigger Re collateralized reinsurance sidecar, which supports its P&C insurance and reinsurance subsidiary Ark, for the 2026 underwriting year, the vehicle continues to serve as a major driver of cash flow, returning substantial capital to the firm throughout 2026 so far.

As reinsurance sidecars increasingly expand into longer-tailed lines of business, the risk profile of these structures is shifting from traditional underwriting toward asset-side management. According to executives at financial and risk advisory firm Kroll, navigating this momentum requires strict asset-liability matching, robust valuation methodologies, and a deep understanding of complex collateral mechanics.

Hiscox Capital Partners, the division of Hiscox Re that encompasses insurance-linked securities (ILS) investments and quota-share partnerships, has appointed Charalambos (Harry) Spanos as a Senior ILS Actuary.

Catastrophe bond fund strategies in the UCITS format saw performance accelerate through recent weeks as seasonality boosted returns, but the 12-month rolling return average across the Plenum CAT Bond UCITS Fund Indices has now declined to just under 10% for the first time this year.

The global reinsurance market is at an inflection point after consecutive strong year’s of underwriting returns have driven robust capital generation, while inflows continue to grow the insurance-linked securities market and alternative forms of capacity, which leads AM Best to call this an inflection point and ask if pricing discipline will last.

Third-party capital in reinsurance, deployed through alternative capital vehicles, catastrophe bonds and insurance-linked securities, is projected to grow roughly 6% over the course of this year, to end 2026 around a record $130 billion level, according to the latest data from AM Best and Guy Carpenter.
