The reinsurance industry is at an inflection point after an exceptionally strong period of improving pricing, robust returns, and rapid balance-sheet growth. For the five years through 2025, reinsurance generated average annual total shareholder returns (TSR) of 19.1%, but one-year TSR decelerated sharply from 29% in 2024 to 14% in 2025, according to BCG’s 2026 Insurance Value Creators Report.
That 14% TSR is still above the 10-year average and reinsurance remains a strong long-term value creator, generating average annual TSR of 13.4% over the ten years from 2016 through 2025. The next phase for reinsurers will depend more on underwriting discipline, capital allocation, operating efficiency, portfolio flexibility, and quality of earnings than on the favorable pricing environment of recent years. All that will be put to the test given the current geopolitical landscape, climate effects, and new, highly correlated risks emerging from AI, such as data centers and business interruption.
Across the 12 reinsurers in our extended sample, tangible book value increased from $119 billion at year-end 2022 to $162 billion at year-end 2025—an 11% annual growth rate. Capital has also continued to build across the broader reinsurance market, with dedicated global reinsurance capital estimated by Gallagher Re at $648 billion at the end of 2025, up 11% from the prior year.
As the industry moves from a market in which favorable underwriting conditions did much of the work to one in which management choices matter more, four areas are of particular importance: risk selection, capital allocation, operating efficiency, and portfolio flexibility. In this environment, success is not measured in premium growth, but value-accretive growth.
BCG’s TSR methodology helps explain why. Shareholder value ultimately comes from three levers: growth in tangible book value, changes in the price-to-tangible-book-value multiple, and cash-flow contribution to shareholders, including dividends and changes in share count. Over the ten years through 2025, cash-flow contribution was the largest component of reinsurance’s 13.4% average annual TSR. Over the most recent five years, value creation became more balanced.
When attractive underwriting opportunities become scarcer, the balance between these three levers is particularly important. This matters because reinsurance underwriting operates on relatively thin margins and with substantial capital requirements. Our P&C reinsurance analysis illustrates the sensitivity. For 2021–2025, our P&C reinsurance benchmarking analysis indicates an average 16% return on tangible equity (RoTE), comprising approximately 7 percentage points from underwriting and 9 percentage points from investment returns. The underlying economics include an average 66% loss ratio and 28% expense ratio—equivalent to a 94% combined ratio. There isn’t unlimited underwriting margin available to absorb price deterioration. A relatively small change in pricing or loss experience can therefore have a disproportionate effect on underwriting returns.
That makes disciplined underwriting more important as competition intensifies. When capital is abundant, success often depends not simply on identifying which business to write, but also on deciding which business not to write. Companies with strong franchises, diversified portfolios, and capital flexibility are in a better position to walk away when business no longer meets their return hurdles.
Our long-term shareholder-return analysis provides some evidence of the importance of those capabilities. Munich Re, Arch Capital, and Hannover Re stand out in our ten-year analysis for combining relatively high average annual TSR with comparatively low volatility of annual shareholder returns, although the five-year analysis shows a more varied competitive picture.
The challenge now is not simply to preserve profitability but to demonstrate the quality and sustainability of earnings as the market normalizes. Two reinsurers can report similar headline returns while having very different underlying economics depending on underwriting performance, investment contribution, reserve development, and catastrophe experience. Investors are therefore likely to pay increasing attention not just to the level of returns, but to how repeatable those returns are throughout the cycle.
Based on our findings in this year’s report, there are five priorities reinsurance CEOs should focus on over the next three to five years to remain attractive to investors:
- Maintain underwriting discipline as pricing normalizes.
- Allocate capital dynamically across products, geographies, and different forms of capital.
- Demonstrate the quality and sustainability of earnings, not simply headline returns.
- Pursue growth where risk-adjusted returns justify it, rather than growing simply to meet a premium target.
- Return capital when attractive deployment opportunities are insufficient.
The next few years will not test who can deploy the most capital. They will test who can allocate it most effectively. In a market where capacity is abundant and pricing is under pressure, sometimes the most value-creating decision is to say no.
