The European insurers generating the strongest returns are not the ones holding the most capital. They are the ones holding the least. That is the central finding of The Era of Deliberate Insurance, published by Howden Re, which benchmarked 42 European non-life insurers across three financial years and four performance measures.
The performance gap between the two extremes is significant. The top group averaged approximately 22% return on equity, a combined ratio of around 90% and a solvency ratio of roughly 186%. The lowest-performing group averaged below 5% return on equity, a combined ratio of around 100% and solvency ratios averaging around 333%. They held approximately €86 of capital for every €100 of premium written. The top group held about €28.
That three-to-one difference in capital deployment produced roughly a quarter of the return.
The research was designed to test whether capital structure explains differences in return. A second question followed: do the best performers share characteristics that others could adopt? The answer to both turned out to be more nuanced than expected.
Capital efficiency matters, but underwriting is the stronger driver of returns by roughly a factor of two. The quarter of the 42 insurers with the best combined ratios averaged around 17% return on equity, while the quarter with the weakest averaged around 4%. Among insurers with strong combined ratios, those running lean balance sheets averaged around 20% return on equity, while those holding surplus capital averaged around 13% on a nearly identical underwriting result. The capital behind the book, not the book itself, accounts for the difference.
“Underwriting and capital efficiency only work together," said Alex Roth, head of alternative solutions at Howden Re International. "A lean balance sheet with a mediocre combined ratio has little to amplify, and a strong underwriter holding far more capital than it needs dilutes its own result.”
The top-performing group spans personal lines specialists, commercial carriers, multi-line leaders and composite groups, including some with foundation or cooperative ownership structures. There is no single model. What they share, the report argues, is a deliberate approach to three things: how well they underwrite, how much risk they retain per euro of premium, and how much capital they hold beyond what the business requires.
The timing of the report reflects market conditions that make its findings immediately actionable. The reinsurance market has shifted decisively towards buyers, with risk-adjusted pricing for property catastrophe treaty business falling by 14.7% at the January 2026 renewals, the largest year-on-year reduction since 2014, Howden Re said in its September 2026 Breaking the Glass pre-renewals report.
That decline has since continued, with Fitch’s Global Reinsurance Monitor: Mid-Year 2026 recording further softening at the mid-year renewals, as dedicated reinsurance capital reached an all-time high of nearly $688 billion, according to Gallagher Re’s mid-year report.
Lower reinsurance pricing is, in the report’s framing, an opportunity to restructure rather than simply save. Insurers that can lower retentions, pass off volatility where they have no pricing edge and reduce the capital sitting behind retained risk are able to do so at a lower cost than at any point since 2014. Those that renew on autopilot, accepting the same programme structure at a lower price, leave that opportunity unused.
“When conditions change, insurers that review their structure deliberately tend to move ahead of those that renew on autopilot," said Julien Masselot, general insurance practice lead, capital and risk analytics at Howden. "The window to do so is usually short.”
The same analysis applies to how insurers manage the asset side of the balance sheet, a dimension the report flags as frequently overlooked. For many in the sample, market risk from investments accounts for a significant share of the capital requirement. The strongest performers hedge that exposure, so the capital on the balance sheet is backing underwriting risk, rather than floating against investment volatility.
The report’s sample is modest, and Howden Re acknowledges the results are indicative rather than statistically significant. The insurers differ in structure, business mix and capital model, and the analysis does not stress-test balance sheets against adverse scenarios. A lower solvency ratio is only a strength, the report notes, if it holds up under stress.
What the data does establish, across three years and four measures and across every combination of those measures, is a consistent pattern. The insurers that treat reinsurance as a capital tool, set a target solvency range and manage towards it, and keep only the risk where they have an underwriting edge, outperform those that do not, regardless of ownership model, size or geography.
