The original discussion about insurance companies accepting small underwriting losses to gain investment capital (float) refers to the traditional insurance business model operating under normal conditions. This is different from the current market disruptions we're seeing in specific high-risk regions.
Insurance companies are indeed leaving certain markets and raising premiums dramatically, but this is happening because:
1. Climate Change Risk Unpredictability
* Traditional insurance models rely on being able to predict risk with reasonable accuracy
* Climate change is making weather-related disasters more frequent and severe
* Historical data becomes less reliable for predicting future losses
* This uncertainty makes it impossible to price policies appropriately
2. Regulatory Constraints
* State regulators often limit how much insurers can charge for coverage
* Companies can't price premiums high enough to cover increasing risks
* They're forced to choose between unsustainable losses or market exit
* Political pressure often prevents charging actuarially sound rates
3. Concentration of Risk
* Some areas face multiple overlapping risks (fire, flood, hurricane)
* Large-scale disasters can trigger many claims simultaneously
* This violates the insurance principle of risk diversification
* Even investment returns can't offset such concentrated losses
4. Scale of Potential Losses
* Traditional model accepts small predictable underwriting losses
* Current climate risks create potential for catastrophic losses
* Example: California wildfires can destroy entire communities at once
* No amount of investment income can offset such massive losses
5. Market Structure Issues
* Some markets require insurers to take all risks (can't be selective)
* Cross-subsidization between markets becoming unsustainable
* State-specific regulations creating fragmented markets
* Limited ability to diversify within regulated markets
While the traditional insurance model can handle planned small underwriting losses offset by investment gains, that model breaks down when facing large-scale unpredictable risks that can't be properly priced or diversified. This explains why insurers are withdrawing from certain markets while still operating profitably in others.
