Commercial property premiums experienced a 1.2% decline in the first quarter of 2026, marking the first downturn since Q3 2017, as outlined in Alliant Insurance Services' 2026 Mid-Year Insurance Marketplace Insights and Observations Report. This report consolidates insights from Alliant's specialized teams across various industry sectors and illustrates a significant shift in the insurance market.
Market Divergence: Property vs. Casualty
The current atmosphere in the insurance sector is characterized by a stark division between property and casualty rates. Property buyers are benefiting from notable price reductions, which range from high single digits to over 20% in some instances, with numerous real estate clients reporting repeated double-digit decreases on renewals. This trend contrasts sharply with the casualty lines, where increased costs have become the norm.
Rates for various casualty lines tell a different story: auto liability costs are reported at increases of 7% to 25%, while umbrella liability is seeing hikes between 10% and 20%. This widening gap highlights a concerning trend within the market that hasn't been witnessed in several years.
Drivers Behind Casualty Pressure
The report points to social inflation and rising litigation as the root causes of these mounting casualty pressures. Over the past decade, social inflation has inflated US liability claims by 57%, drastically affecting casualty pricing structures.
Adding to this complexity, the United States Supreme Court's ruling in Montgomery v. Caribe Transport II has introduced further liability exposure in the transportation sector, holding freight brokers accountable for negligent carrier selections. This legal precedent is likely to exert upward pressure on primary and excess insurance costs within this field.
Cyber Insurance Landscape
Despite a marked increase in ransomware attacks—four times higher in 2025 compared to 2020 and 50% higher than 2024—cyber insurance rates have remained largely stable. Most industries are experiencing negligible to slight decreases in renewal rates, although the healthcare sector and public entities have noted declines ranging from 5% to 10%.
Alternative Risk Markets on the Rise
The insurance-linked securities (ILS) market has flourished, posting a record issuance of $25.6 billion in 2025—an increase of 44.6% from the previous year. Outstanding ILS value is now at $61.3 billion, with 2026 issuance reaching $15.5 billion by early May. Although spreads remain elevated at 5.61%, they have declined from peaks seen in 2022 to 2024.
Concurrently, the global parametric market has also expanded, valued at over $19 billion in 2025. Its growth trajectory is poised to continue at a double-digit rate over the next decade as coverage areas broaden from traditional triggers to include diverse areas such as cyber risks, droughts, and weather-based conditions.
Sector-Specific Insights
The captive insurance market is becoming increasingly vital for companies grappling with challenging lines. An estimated 7,000 to 8,000 licensed captive insurers exist, with potential group captives numbering close to 50,000 when factoring in various arrangements. Nevertheless, alternative risk financing costs are climbing due to pressures from labor and reinsurance costs.
Healthcare remains one of the most pressured sectors, with hospital professional liability rates fluctuating between 8% and 35%. The complexity of building a robust excess liability tower now calls for significantly more carriers compared to past years, and restrictive practices persist regarding sexual abuse and misconduct coverage.
Trends in Construction and Life Sciences
In the construction scene, data centers emerge as a growth driver amid surging demand for AI and cloud computing. Yet, challenges in auto liability and umbrella coverage persist across contractor projects, illustrating ongoing pressure points.
In the life sciences sector, biopharmaceutical deal activity has surged, with aggregate values exceeding $90 billion through the first three quarters of 2025. Nearly 80% of executives in this field anticipate AI's transformative impact on their industry.
Looking at the broader picture, Verisk and the American Property Casualty Insurance Association (APCIA) report an estimated underwriting gain of $63 billion in 2025, mostly attributed to historically low catastrophe losses rather than risk management improvements. For real estate stakeholders, distress in the office space has intensified, indicated by a 12.34% delinquency rate in commercial mortgage-backed securities—a record high.
In this evolving market, buyers equipped with solid data and effective risk management strategies are obtaining favorable terms in property insurance. Conversely, those lacking these advantages may find themselves navigating a more selective market.
