During its reinsurance renewals for 2025, US insurer Progressive added a novel parametric severe convective storm aggregate reinsurance arrangement, to provide it with responsive aggregate protection for qualifying thunderstorm, hail and tornado loss events.

Having purchased aggregate retrocessional reinsurance and secondary peril protection earlier this year after the California wildfires, reinsurer Conduit Re intends to continue evolving its retrocession strategy in 2026, to better protect against these types of events, its CEO Neil Eckert explained this week.

US primary insurer Allstate has purchased a new aggregate reinsurance cover for its US homeowners business at the mid-year renewals, adding what is a new protection feature for the company that covers events greater than $1 million and will provide $325 million of placed aggregate limit, across a $500 million layer excess of a $3.5 […]

Improved pricing, greater competition, and a notable increase in capacity helped drive stronger retrocession and aggregate cover placements at the 2025 mid-year reinsurance renewals, according to broker Aon.

The market for aggregate reinsurance coverage remains “fraught” with a wide gap between bid and ask, Greg Hendrick, President and CEO of Vantage Risk has explained, but his firm still finds opportunity in that area of coverage, deploying capital through its AdVantage collateralized insurer class of company in 2025.

News continues to emerge that reflects the increased availability of aggregate reinsurance protection, as an analyst report shows Italian insurance and financial services group Unipol secured a planned €300 million aggregate reinsurance treaty to better protect it against smaller catastrophes and weather losses.

European insurers are increasingly revisiting aggregate catastrophe cover to protect against high-frequency events, with alternative capital providers showing greater interest in supporting these structures, according to Hamish Dowlen, Managing Director and Head of EMEA at Gallagher Re.

The final week of May brought a wave of damaging severe convective storms and flooding across the southern United States, with insured losses likely to reach into the billions, according to global insurance and reinsurance broker Aon.

Severe convective storm (SCS) activity across the United States has now cost the insurance and reinsurance industry more than $20 billion in 2025, broker Gallagher Re estimates, with its Chief Science Officer Steve Bowen highlighting that the May 14th to 20th outbreak could drive insured losses of up to $7 billion.

Due to the extensive tornado, hail, and wind damage across the central and eastern United States, global insurance and reinsurance broker Aon has indicated that a recent outbreak could be among the most expensive severe weather events in U.S. history on an inflation-adjusted basis.
