Aon launched its Ultimate Guide to the Reinsurance Renewal report, which contrasts the robust financial results of the reinsurance industry against a backdrop of insurer losses and increasing complexity of risk.
The report reinforces the untapped growth potential of the industry, highlighting that the key ratio of global insurance premium to gross domestic product has remained at approximately 1.8% since 2010, despite exposure growth and unmet client need.
Despite global natural catastrophe re/insurance payouts reaching $58 bn during the H1 2024 – well above the first half decadal average of $47 bn – reinsurers achieved an average common return on equity of 17.6 percent during the same period.
Some of the industry’s largest reinsurers reported an return on equity (ROE) of more than 25% – well above that of most primary insurers and their own cost of capital – which could lead to higher growth, according to Aon’s performance analysis of 100 global re/insurers (see Top Tips for 2024 Reinsurance Market Renewals).
Global Reinsurer Capital, $ bn

However, higher retentions in insurers’ catastrophe programs reduced capacity for frequency covers and resulted in an unequal distribution of underwriting profit across the insurance value chain.
The report reveals that global reinsurer capital reached a record high of $695 bn at June 30, 2024 – an increase of $25 bn compared to year end 2023.
This increase was principally driven by retained earnings, new inflows to the catastrophe bond market, and recovering asset values – where a survey group of re/insurers saw average annualized ordinary investment yields of 3.8% for the H1 2024, up from 3.1% during the prior year period.
Renewals in 2024 have seen reinsurance pricing gradually decrease, partly due to an increase in alternative capital to $110 bn, and with rate reductions granted by reinsurers for the best performing risks.
Aon forecasts an increase in pricing competition in 2025, and that insurers will begin to see greater flexibility around capacity provision and coverages.
If the reinsurance market is to provide real value, it must play a more active role in helping insurers to manage frequency losses and earnings volatility
Rupert Moore, UK CEO of Reinsurance Solutions for Aon
If reinsurers continue to run from risk, it will force insurers to follow suit and we will all become part of a shrinking, and less relevant industry.
The report highlights that re/insurers experienced significant volatility in 2024, with diverse events including earthquake and airline losses in Japan; the Baltimore bridge collapse in the U.S.; historic flooding in Dubai, and the CrowdStrike global computer outage.
“Such losses reinforce recurrent, yet critical, themes for the industry – the growing interconnectivity and complexity of risk, volatility of losses, and the widening gap between insured and economic losses. The industry can either lean into the opportunities created by a world of changing risk or retrench and watch as a greater proportion of risk is retained or shifts to the public sector and capital markets.” Moore added.
