Casualty Insurance: Rates Climb, Coverage Tightens 

While property lines are showing early signs of stability, casualty insurance is under increasing pressure—with rates rising an average of 8% in Q1 2025. The upward trend is driven by a convergence of factors: 

  • Social inflation and nuclear verdicts continue to fuel loss severity, particularly in general liability and auto liability. 
  • Emerging risks—such as PFAS contamination, biometric data violations, and toxic torts—are triggering tighter underwriting and broadening exclusions. 
  • Professional liability markets remain competitive, but D&O insurers are retreating from underpriced excess layers, citing unprofitability and legal volatility. 

Brokers should be proactive in managing expectations with clients—especially in industries facing regulatory scrutiny, ESG litigation, or evolving cyber liabilities. For a deeper dive, see WTW’s Spring 2025 update and Ryan Specialty’s market outlook. 

Regulatory Watch: New Reinsurance Testing and Class Action Risk 

Two key regulatory developments are gaining traction at the NAIC and in U.S. courts: 

  • The NAIC’s Life Actuarial Task Force is on track to finalize a new Actuarial Guideline for Reinsurance Asset Adequacy Testing (AAT) by June 2025. This move would standardize reserve testing for asset-intensive life insurers and increase disclosure obligations. 
  • Implementation will affect 2025 annual statements, with full disclosure rules kicking in by April 2026. 
  • The goal: more transparency around the quality and adequacy of assets backing reserves, especially in reinsurance-heavy portfolios. [Sidley Austin summary] 
  • On the property & casualty side, Q1 2025 saw a spike in class action litigation, particularly around total loss vehicle claims and disputes over scope-of-loss adjustments. These cases are refining legal precedents and liability theories—posing significant exposure for carriers and clients alike. [Mondaq]  

California Wildfires Prompt State Farm Rate Hearing 

After wildfires devastated the Los Angeles region in early 2025—causing over $1 billion in insured losses and destroying more than 16,000 structures—State Farm requested an emergency 22% rate hike for non-tenant homeowners in California. That request has now been scaled back to 17%, with hearings underway at the California Department of Insurance. 

Other proposed hikes include: 

  • 15% for renters and condo unit owners 
  • Up to 38% for rental dwelling policies 

State Farm’s financial justification includes a stark drop in surplus—from $4 billion in 2015 to just $600 million in 2024. Consumer advocacy groups, however, are challenging the increases, citing affordability concerns and a need for transparency. 

The final ruling is expected following a full evidentiary hearing in June. [California Globe] 

New CAT Behavior Data: Coverage Cuts vs. Resilience Building 

A new Nationwide Agency Forward Commercial Lines Protection Survey reveals how commercial property owners and agents are reacting to the rising frequency of climate-driven catastrophes. 

Key Findings: 

  • 1 in 3 commercial properties nationwide has suffered damage from a natural disaster in the last five years. 
  • This rises to over 50% in wildfire-risk states and nearly two-thirds in hurricane-prone areas. 
  • Among agents, 93% in wildfire states and 86% in hurricane states say they are “very” or “extremely” concerned—up sharply since 2023. 

Despite increased awareness, cost pressures are driving difficult tradeoffs: 

  • 42% of property owners say they would reduce coverage to lower premiums. 
  • 54% have dropped optional coverages in the past year. 
  • Many are turning to bundling (69%) and shopping multiple carriers (56%) to manage costs. 

At the same time, the survey highlights a growing emphasis on resilience: 

  • Over 90% of stakeholders support prioritizing building code compliance as a mitigation strategy. 
  • However, barriers like construction costs, business interruption risk, and access to guidance are slowing adoption of retrofitting and upgrades.

Inflation Pressure Persists in Claims Costs 

In its latest quarterly update, QBE Insurance Group reported that while claims remain within budget for 2025, inflation remains a key concern. The carrier notes: 

  • Claims cost inflation—particularly in building materials, replacement parts, and labor—is continuing to pressure margins. 
  • Property and casualty lines with CAT exposure and supply chain dependencies are the most vulnerable. 

This comes as the industry continues to digest a $21.2 billion net underwriting loss in 2024, according to AM Best—driven by catastrophe losses and loss ratio deterioration in lines like homeowners and commercial auto. [AM Best report summary] 

Key Takeaways for Brokers 

  • Casualty volatility is here to stay. Prepare clients for rising rates and stricter terms, especially in high-risk sectors. 
  • Reinsurance regulations are tightening. Watch for capital and disclosure requirements that may affect life and P&C pricing. 
  • Wildfire and CAT-prone clients face pricing shifts. Stay ahead of rate filings and risk eligibility criteria. 
  • Clients are cost-cutting—but resilience matters. Guide insureds toward sustainable risk management, not just cheaper premiums. 
  • Monitor inflation closely. High deductibles and accurate valuation updates will be essential to avoid surprises at claim time.
