The diversity and flexibility of reinsurance capital evidenced at the April 1 renewal highlights the expanding opportunity for insurers to strategically explore all forms of capital to lower their cost, manage earnings volatility and support growth as the industry moves through the insurance cycle, Aon’s recently launched Reinsurance Market Dynamics April 2026 Renewal report says.

Insurers renewing at April 1 achieved significant savings in all regions, building on the competitive conditions seen at January 1. Record levels of industry capital, aggressive competition from ILS markets and relatively benign catastrophe losses in Asia Pacic helped drive double-digit reductions and more flexible terms and conditions at April 1, the main renewal for insurers in Japan, Korea and India.

The report finds that reinsurance buyers purchased higher limits to support profitable growth at the April 1 renewal as global reinsurance capital reached a record USD 785 billion. The abundant capital environment enabled insurers to access broader protection and optimize program structures with double‑digit rate reductions, notably across key Asia Pacific markets.

Global demand for reinsurance increased by approximately 10% at the April 1 renewal, as buyers used favorable market conditions to secure more comprehensive protection, with some expected to return to the market post‑renewal to explore additional purchases. In certain Asia Pacific markets, rate reductions of up to 20% underscored the strength of buyer leverage supported by abundant capacity.

Reinsurers achieved an average return on equity (ROE) of 17%, marking a third consecutive year of strong underwriting and retained earnings, supported by robust investment performance. Aon forecasts that reinsurers’ ROEs will continue to exceed their cost of capital in 2026, should ceded losses remain within expected ranges, while noting that rising geopolitical tensions – including the Middle East conflict – and capital market volatility may introduce greater uncertainty across the global economy.

“Taking a proactive, strategic approach to using reinsurance capital as an enabler allows our insurer clients to embrace risk and drive profitable growth ambitions through 2026 and beyond. In this environment, reinsurance provides insurers with powerful tools to manage volatility, protect profitability and invest confidently in new lines of business, geographies and emerging risks, as well as pursuing inorganic growth opportunities – a key trend highlighted in our report. Such actions will help insurers outperform peers as the market cycle evolves”, said George Attard, chief strategy officer and global head of analytics for Aon’s Reinsurance Solutions.

“As volatility increases and primary market competition intensifies, insurers are increasingly using reinsurance as a strategic tool rather than a purely transactional purchase. Buyers are exploring a broader mix of solutions – including facultative reinsurance, portfolio facilities, proportional covers and multi‑year arrangements – to smooth earnings, lower cost of capital and support long‑term planning”, commented Alfonso Valera, International CEO for Aon’s Reinsurance Solutions.
