Short answer: If an insurance company’s models aren’t good at predicting risk, the firm can face financial strain, pricing and reserving problems, regulatory scrutiny, and reputational harm, which together threaten solvency, competitiveness, and customer trust. Below is a concise breakdown of typical stakes and mechanisms.
Financial and pricing risks
- Underpricing and reserve shortfalls: Poor risk prediction can cause policies to be priced too low or reserves to be insufficient for anticipated claims, increasing the probability of underwriting losses and, in the worst cases, solvency concerns.
- Volatility of claims experience: Inaccurate risk estimates lead to higher claim volatility, making earnings harder to forecast and potentially triggering capital management challenges.
Profitability and competitiveness
- Reduced profitability: Systematic mispricing raises claims costs relative to premiums, squeezing margins and profitability over time.
- Loss of market share: If competitors offer better-priced or better-calibrated products, customers may migrate, especially in price-sensitive lines like auto and property insurance.
Operational and governance risks
- Model risk and decision quality: Inadequate governance over models can produce unreliable outputs, impairing underwriting decisions, pricing, and capital allocation.
- Regulatory and reporting risks: Regulators scrutinize model risk management; poor oversight can lead to regulatory actions, fines, or mandated remediation, particularly where models affect reserving or pricing assumptions.
Reputational and strategic risks
- Reputation damage: Consistent mispricing or adverse outcomes can erode consumer trust and make marketing and customer acquisition more difficult.
- Strategic misalignment: If models fail to capture emerging risk factors (e.g., climate-related losses, behavioral changes), strategies may drift away from actual exposure, reducing long-term resilience.
Potential knock-on effects
- Higher premiums for existing customers: To cover losses or capital costs, insurers may raise premiums, prompting churn and further loss of scale.
- Increased capital requirements: Persistent model risk can necessitate higher holdbacks or solvency capital, tying up capital that could be deployed elsewhere.
- Insurer distress or failure (extreme): Severe mispricing and reserve inadequacy can lead to insolvency events in the worst cases, especially for smaller players with thinner capital buffers.
