Hannover Re has successfully completed the latest iteration of its Acorn Re parametric catastrophe bond series, significantly increasing its protective capacity to $240 million. This sixth transaction, officially named Acorn Re Ltd. (Series 2025-1), provides essential reinsurance coverage, particularly for earthquake risks along the U.S. West Coast. Notably, the final spread paid to investors for this bond was lower than originally anticipated, underscoring favorable market conditions characterized by robust investor interest and enhanced risk assessment methodologies.
Initially launched with a target of $200 million, the Acorn Re 2025-1 deal quickly saw its size target uplifted due to strong market receptivity. The reinsurance market has consistently demonstrated an appetite for new catastrophe bond issuances, often leading to both an expansion in size and a reduction in pricing for such instruments. This trend was evident as the target size was first revised to between $225 million and $275 million, accompanied by a corresponding decrease in the projected price spread.
Ultimately, the issuance finalized at $240 million, representing a 20% increase from its initial offering. The pricing for the Class A notes settled at a spread of 2.35%, falling below the initial guidance range but comfortably within the revised, lower bracket. This reflects not only heightened investor confidence but also improvements in the underlying modeling and parametric trigger structures designed for these bonds, which have become more sophisticated over time. Such advancements enable sponsors like Hannover Re to secure long-term, fully collateralized reinsurance solutions at more attractive costs.
The protection offered by the Acorn Re 2025-1 series extends to Kaiser Permanente’s workers' compensation captive, Oak Tree Assurance Ltd., covering its exposure to earthquake risks, primarily in California. Additionally, other reinsured entities of Hannover Re with earthquake exposure within the defined parametric trigger zones will benefit from this coverage. This multi-year, per-occurrence parametric reinsurance is triggered by specific earthquake events on the U.S. West Coast, providing a clear and efficient mechanism for risk transfer.
Comparing the 2025-1 notes, with an expected loss of 0.96% and a final spread of 2.35%, yields a multiple-at-market of 2.45 times the base expected loss. This figure represents the lowest spread multiple seen across the entire Acorn Re parametric catastrophe bond series to date. This indicates a highly efficient risk transfer solution for Hannover Re, allowing them to capitalize on current market dynamics where strong investor demand and ample capital converge to drive down the cost of reinsurance protection. The continuous refinement of modeling techniques and parametric trigger mechanisms contributes significantly to this improved pricing efficiency, benefiting both the sponsor and ultimately the insured parties.
