Autonomous, a financial research and analytics firm, reports that the reinsurance sector is navigating a persistently soft market, with solid profitability continuing to influence renewals.
According to Autonomous, the first month of the year saw reinsurers underperform relative to expectations, with renewal outcomes slightly weaker than anticipated.
However, Autonomous notes that a moderately positive results season, combined with cautious investor sentiment, has supported the sector. European reinsurers are now broadly flat year-to-date, while Bermudan peers average a gain of 1.5%.
In Autonomous’s assessment, reinsurers have outperformed broader sector indices on both sides of the Atlantic, supported by low-beta profiles, limited leverage, strong capitalisation, and a generally benign loss environment amid a challenging equity market.
European reinsurers, Autonomous reports, have outperformed the sector by 3% YTD (unweighted), while US and Bermudan reinsurers have outpaced the US insurance index by 8%.
Autonomous’s analysis of April renewals indicates that the buyer-favoured market conditions observed in January have persisted. The firm notes that property catastrophe rates have fallen by mid-to-high teen percentages, sometimes compounding reductions seen in the prior year.
Autonomous emphasises that, despite these declines, starting points remain elevated following the post-2022 pricing reset, and brokers do not see the rate changes as irrational.
According to Autonomous, competitive pressures are particularly apparent in lower property layers, and may also reflect continued growth in alternative capital markets, including insurance-linked securities.
The firm observes that rate reductions are most significant in property and specialty lines, while casualty remains relatively stable. Autonomous also highlights ongoing uncertainty around aggregate and frequency protections, which influences how losses are transferred from primary insurers to reinsurers.
Autonomous points out that the current pricing trends have largely been underpinned by a benign loss environment, particularly for natural catastrophes, and reinforced by strong capital buffers. While geopolitical risks, such as the Middle East conflict, could introduce uncertainty, Autonomous reports that these factors have had limited impact on renewals to date, confined mainly to specialty exposures.
Looking ahead, Autonomous warns that double-digit rate declines suggest the era of supernormal profitability may begin to ease, though the firm believes earnings potential remains sufficient to deliver mid-to-high teen returns on equity. Autonomous notes that management teams have maintained confidence in meeting earnings targets and in building additional buffers, a view that April renewals have not materially altered.
Autonomous highlights that mid-year renewals, particularly in US catastrophe-focused segments, are expected to be more closely watched. Early indications suggest that rate declines could mirror those seen in April, given subdued hurricane activity in 2025 and limited US mainland impact.
The firm observes that early signs of slips in excess-of-loss terms and conditions will be monitored, especially as the US has historically accounted for a significant share of losses from severe convective storms, fires, and wind events.
Autonomous concludes that the conditions required to drive a meaningful positive shift in pricing remain distant. The firm emphasises that abundant capital and a continued benign loss environment support high profitability.
Autonomous identifies the most likely catalysts for rate increases as a major capacity-draining event—either a single catastrophic loss exceeding $110–125 billion, or an aggregation of extreme losses—which could materially change market dynamics.
Even so, Autonomous notes that such an event would be consistent with the “new normal” of insured catastrophe losses, in line with Verisk’s estimates of a 1-in-20-year aggregated annual loss.
