Aon says record reinsurance capital is fueling insurer growth ambitions

Aon says reinsurance buyers entered the April 1, 2026 renewal with unusually strong leverage, supported by a record $785 billion in global reinsurance capital. According to the firm, that capital strength helped insurers buy more protection, secure broader structures, and push through double digit rate reductions in several markets, particularly across Asia Pacific.

Demand rose by about 10% at the renewal, with insurers purchasing higher limits, additional frequency cover, and retention buy downs to support growth while protecting earnings. Aon also said reinsurers posted an average 17% return on equity, giving the market confidence to stay competitive even as geopolitical risk and capital market volatility remain in the background.

The bigger takeaway is that insurers are not just using reinsurance defensively. Aon frames it as a growth tool, with buyers using favorable conditions to lower costs, improve capital efficiency, and expand into new business lines, geographies, and risk categories.
