Homeowners’ multiple peril, by far the largest property insurance line, generated nearly half of all property premiums but also shouldered more than half of the losses, posting a 58.8% loss ratio. In sharp contrast, smaller and mid-sized segments such as fire insurance and inland marine quietly delivered stronger results, with loss ratios in the mid-30s to mid-40s.
Overall, property sub-lines wrote $272 billion in premium last year against $141.5 billion in losses, for a weighted loss ratio of 52%. But beneath the surface, dispersion was stark: earthquake insurance barely registered losses at all, while federal flood soared to a 134% ratio.
For carriers, the map matters. The data, drawn from IBA’s Property & Casualty LOB Performance & Market Trends dashboard, suggests that allocating more capacity to sturdier mid-tier lines like fire, inland marine and commercial multiple peril liability could provide steadier returns. Meanwhile, homeowners’ exposure may demand tighter ring-fencing against catastrophe risks and inflation-driven claim costs.
The full report ranks each property sub-line by premium, loss share and ratio, offering a clear-eyed view of where insurers can still find resilience – and where volatility is testing the market’s limits.
Rebalance portfolios toward sturdier mid-sized cohorts. Increase exposure where premium share is meaningful and 2024 loss ratios sit at or below the median (e.g., fire, inland marine, commercial multiple peril – liability).
Tightening homeowners underwriting levers. Prioritize hazard-by-hazard refinement, higher deductibles in peak-cat zones, and stricter roof age/material criteria to counter a 58.8% loss ratio.
Calibrate reinsurance and capital for tail lines. Stress test federal/private flood and homeowners’ layers to ensure volatility is capital-compatible under plausible event sets.
Target niches with favorable experience. Consider selective growth in private flood while monitoring accumulation risk and coverage terms.
Use the Property & Casualty LOB Performance & Market Trends dashboard to operationalize this. Filter to Property sub-LOBs, rank by “Loss Ratio (%)” and “Premium Share (%)”, and compare loss share vs premium share. Save a benchmark view anchored to the median loss ratio and revisit quarterly to track drift.
Flexible filtering and deep-dive analysis – Navigate with an intuitive filter panel and access a dedicated subcategory analysis page for customized views of ratios, trends, and underlying structures.
Clear methodology and formulas – Built on calendar-year US state data, the dashboard applies standardized calculations (loss, expense, combined, and defense-to-loss ratios) to ensure clarity and consistency.
Transparency on variability – Aggregated values may reflect a ±1–3% variance due to rounding or reporting differences - context that helps users interpret results with confidence.
Up-to-date with LOB reclassifications – Tracks recent changes (e.g., inland marine split, medical liability and product liability refinements) to maintain accuracy while highlighting how redefinitions affect historical comparisons.
