A LETTER TO OUR READERS

Unlocking potential in unpredictable times

Vince Gaffigan U.S. Market Strategy & Engagement Group Leader Lockton

As the first quarter of 2026 comes to a close, the commercial P&C insurance market appears to have reached a more stable equilibrium, producing solid returns while remaining broadly competitive.

Throughout 2025, insurers benefited from disciplined pricing, improved risk selection, and strong investment income. Although catastrophe activity and casualty severity continued to pressure results, the industry still delivered improved profitability, backed by investment yields that were at their highest level in more than a decade. This drove combined ratios1 down, indicating underwriting profitability, and returns on capital up.

To be sure, performance varied by line. Short-tail and specialty classes did well, while long‑tail casualty remained a challenge.

Looking ahead, macroeconomic conditions remain generally favorable but increasingly complex. The U.S. economy continues to defy expectations, even as shifts in trade policy, geopolitical tensions, and political dynamics introduce additional volatility. Tariff threats and supply chain realignment are raising costs and increasing contractual and cross-border risk complexity. At the same time, continuing uncertainty around interest rates, regulation, and geopolitical alignment is shaping insurer and buyer decision‑making.

Cooling labor markets may dampen premium growth but could relieve some frequency‑driven losses. However, structural severity drivers — including medical inflation, social inflation,2 and litigation funding — continue to burden casualty lines. As a result, pricing pressure persists, and insurers continue to prioritize tail risk, program structure, and aggressive litigation risk management. A stable casualty reinsurance market continues to provide support, influencing capacity3 and terms.

Capital remains plentiful but increasingly fragmented and targeted. Traditional carriers now compete with alternative capital sources targeting specific risk segments. This has expanded choice in some areas while reshaping how risk is underwritten and retained. The push for adequate returns may further accelerate M&A activity as carriers seek scale, specialization, and efficiency.

Stronger investment portfolios continue to support earnings. But as interest rates normalize, underwriting performance — especially in long‑tail lines — will again drive profitability expectations.

The market has become more competitive for well‑understood, controllable risks and more selective where uncertainty persists. Property, cyber, and certain specialty lines offer attractive opportunities, while excess casualty and umbrella remain disciplined due to severity concerns.

Looking ahead, 2026 will be defined by informed decision‑making more than dramatic shifts. Election year dynamics, geopolitics, regulatory change, and rapid AI adoption elevate uncertainty, making early engagement, strong use of analytics, and thoughtful program design increasingly essential.

We look forward to continuing our conversation with you.

1Combined ratio: A key measure of underwriting profitability for P&C insurers and reinsurers. It is calculated by dividing the sum of incurred losses and expenses by earned premiums. Any number below 100 (or 100% when expressed as a percentage) indicates an underwriting profit; any number above 100 indicates an insurer or the market is paying out more in claims and expenses than it makes in premiums. Combined ratios can be calculated on an accident year or calendar year basis. (See glossary.)

2Social inflation: The increase in insurance claim costs beyond general economic inflation, driven by changes in societal attitudes, legal environments, and litigation behavior. Contributing factors include expanded theories of liability, higher jury awards, broader interpretations of coverage, and increased plaintiff attorney activity. Social inflation is most prominent in U.S. casualty lines, including auto liability and general liability, and some management liability coverages. (See glossary.)

3Capacity: In P&C insurance, capacity refers to the maximum amount of risk an insurer, reinsurer, or the overall marekt is willing or able to underwrite. Capacity is determined by capital levels, risk appetite, pricing adequacy, and regulatory constraints. It can apply to policy limits, total exposure, or the number of policies written within an individual line or geographic location. (See glossary.)
