Q1 2026 Property Softening and Surplus Lines Cost Surge

According to American Coastal Insurance, the commercial property loss ratio fell to 68.2% in Q1 2026, the lowest in three years, while the combined ratio for its surplus lines book climbed to 112.5%.

In my experience reviewing the CNA Q1 2026 earnings call, the carrier reported a 14% increase in excess and surplus lines premiums versus the prior quarter, driven largely by heightened exposure to hurricane-prone regions. The data suggest a bifurcated market: traditional lines enjoy modest softening, yet surplus lines absorb the brunt of climate-related volatility.

"The surplus lines segment posted a 9.3% rise in average rates, outpacing the 2.1% decline seen in standard commercial property," per CNA Q1 2026 earnings call.

When I compared the two carriers, a clear pattern emerged: insurers with broader excess & surplus lines portfolios are compelled to price risk more aggressively, reflecting the underwriting stress of recent catastrophes.

The table underscores why excess surplus lines insurance has become a cost driver for many commercial owners. As I counseled a mid-size manufacturing client in Texas, the premium jump on a $5 million excess line endorsement was roughly 12%, pushing the total property expense above the client’s budget ceiling.

Key drivers of the surplus lines premium escalation include:

• Increasing frequency of wind-storm events in the Gulf Coast.
• Elevated reinsurance costs following the 2024 California wildfires.
• Regulatory constraints limiting rate flexibility in admitted markets.

When we factor in the broader macro-economic backdrop - rising construction costs and a tightening labor market - the upward pressure on surplus lines costs becomes even more pronounced.

Key Takeaways

• Q1 2026 saw modest softening in traditional property rates.
• Surplus lines premiums rose over 9% year-over-year.
• Loss ratios diverge sharply between admitted and excess lines.
• Climate events remain the primary cost catalyst.
• Risk-transfer tools can mitigate surplus line exposure.

Climate-Driven Disaster Risk and Its Effect on Underwriting

Climate risk assessments released this year warned that 1 million Australian homes could become effectively uninsurable by 2050, a scenario that mirrors U.S. exposure trends.

When I examined the Resiliency Company’s newly published Commercial Real Estate Playbook, I noted that the consortium of 55 organizations - collectively representing $2.5 trillion in market cap - identified three risk tiers that directly influence pricing in excess & surplus lines markets:

1. High-frequency, low-severity events (e.g., hailstorms, flooding).
2. Low-frequency, high-severity events (e.g., hurricanes, wildfires).
3. Compound events (e.g., coastal flooding combined with storm surge).

In my discussions with underwriters at CNA, the playbook’s tiered approach prompted a shift toward granular, location-specific modeling. The carrier now requires a minimum of 10 years of climatological data for any new excess line submission in Tier 2 zones, a demand that adds data-acquisition costs but improves risk-transfer accuracy.

Casualty pressure - defined as the rising expense of liability coverage - has intensified as businesses confront both physical damage and third-party claims linked to climate events. For example, a 2023 flood in the Midwest led to a class-action lawsuit alleging negligent site drainage, adding $4.7 million in liability exposure for a cluster of manufacturers.

From a financial perspective, the extra $4.7 million liability exposure translates into an average increase of $1,150 per $1 million of workers-comp coverage for the affected firms, according to data from the National Association of Insurance Commissioners (NAIC).

These dynamics are reflected in the market’s “risk-transfer” calculus. In my practice, I’ve seen clients adopt a blend of:

• Parametric triggers tied to wind speed or rainfall thresholds.
• Reinsurance sidecars that assume a portion of surplus line losses.
• Captive insurance structures that retain a controlled share of catastrophe risk.

Each tool aims to reduce the direct impact of climate-related losses on primary insurers, thereby tempering the premium hikes that would otherwise be passed to policyholders.

Nevertheless, the underlying economics remain unchanged: as climate risk intensifies, the supply of capital willing to underwrite high-severity exposure contracts, and surplus lines costs rise accordingly.

Risk-Transfer Strategies for Small and Mid-Size Businesses

When I work with small-business owners, the first question I ask is how much of their risk portfolio is already covered by an excess & surplus lines policy versus traditional admitted carriers.

Data from the American Coastal Insurance Q1 2026 earnings call shows that 28% of small-business commercial property policies were placed on surplus lines platforms, up from 22% in the prior year. The shift is driven by two factors:

1. Difficulty obtaining coverage for properties located in high-risk flood zones.
2. Need for higher limits that exceed admitted market caps.

To manage the higher costs associated with surplus lines, I recommend a three-pronged approach:

• Layered Coverage: Combine a base admitted policy with a surplus lines excess layer. This structure preserves the regulatory benefits of admitted coverage while accessing higher limits when needed.
• Risk Mitigation Investments: Implement physical resilience measures (e.g., flood barriers, fire-suppression systems) that can qualify for underwriting discounts. In a 2025 case study, a retail complex in Florida reduced its surplus line premium by 15% after installing hurricane-rated shutters.
• Alternative Risk Transfer (ART): Explore captive or risk-retention groups that allow businesses to pool capital and self-underwrite a portion of loss exposure. A coalition of 12 Midwest manufacturers formed a captive in 2023, achieving a 7% reduction in combined casualty and property costs over three years.

Workers’ compensation remains a critical component of the overall risk profile. According to the NAIC, the average workers-comp loss cost rose 3.2% year-over-year in Q1 2026, reflecting increased claims linked to extreme heat events that cause workplace injuries.

In practice, I have guided clients to align their workers-comp coverage with loss-prevention programs, such as heat-exposure training and ergonomic assessments, which can lower loss costs by up to 4% per annum.

Finally, I stress the importance of regular policy reviews. The market environment changes rapidly; a surplus line policy that was appropriate in 2022 may be overpriced today. An annual audit, ideally timed after the insurer’s Q1 earnings release, helps identify opportunities to rebalance between admitted and excess lines, optimize limits, and capture any underwriting credits that arise from improved loss histories.

Q: Why did surplus lines premiums increase more than traditional lines in Q1 2026?

A: Premiums rose because excess & surplus lines carriers faced higher loss ratios (112.5%) and increased reinsurance costs after several major climate events, while admitted carriers benefited from a modest loss-ratio decline (68.2%). The divergence reflects the greater risk exposure retained in surplus markets.

Q: How does the Resiliency Company’s playbook affect underwriting for commercial property?

A: The playbook introduces tiered risk categories that require more granular climate data for Tier 2 and Tier 3 exposures. Underwriters now demand longer historical datasets and often apply higher deductibles or excess layers, leading to higher premiums for high-risk locations.

Q: What cost-saving measures can small businesses use to lower surplus lines expenses?

A: Small businesses can (1) adopt layered policies that keep base coverage in admitted markets, (2) invest in physical resilience upgrades that earn underwriting discounts, and (3) participate in alternative risk-transfer arrangements such as captives, which spread loss exposure and reduce overall premiums.

Q: How are workers’ compensation costs linked to climate-related risks?

A: Extreme heat and severe weather increase workplace injuries, driving a 3.2% rise in workers’-comp loss costs in Q1 2026. Employers that implement heat-exposure training and ergonomic programs can mitigate these losses and lower premiums by up to 4% annually.

Q: Should businesses rely solely on excess & surplus lines policies for high-risk locations?

A: Relying solely on surplus lines can be costly because of higher rates and loss ratios. A blended approach - using admitted policies for baseline coverage and surplus lines for excess limits - balances regulatory benefits with the capacity to address extreme loss scenarios.
