An insurer is paid before it knows what its product cost, and invests the money in the meantime. Profit therefore comes from two sources that must both work: pricing risk better than rivals, and earning a return on the float those premiums create. The Insurance template scores that pair, along with the capital that lets a company survive the year in which the losses arrive together.
Underwriting Discipline
Not measurable
· 25% of the moat score
Underwriting discipline is the core insurance moat, and it consists mostly of the willingness to lose business. Premium is easy to win by underpricing risk, and the mistake stays invisible until claims come in years later. A company that earns a consistent underwriting profit through both a soft market and a hard one is selecting risk better than whoever took the business it walked away from.
Float Investment Quality
Not measurable
· 20% of the moat score
Float is the money an insurer holds between collecting premiums and paying claims — capital it invests but does not own. Float generated at a genuine underwriting profit costs less than nothing, and a disciplined investment return on it compounds into the dominant source of value at the best insurers. Consistency matters far more here than a high return in any single year.
Pricing Power
Not measurable
· 18% of the moat score
For an insurer, pricing power is the ability to push rate ahead of claims inflation and keep the policyholders anyway. It comes from brand, distribution, or a specialty line with few credible competitors. The signature is premium growth accompanied by a stable or improving margin — growth alongside a deteriorating margin usually means the market is repricing against the insurer, not for it.
Capital Strength & Solvency
Not measurable
· 17% of the moat score
Capital is what lets an insurer credibly promise to pay a claim that has not happened yet, and it is scrutinised by regulators and rating agencies alike. A strong balance sheet is also commercial: it wins business from buyers who care about counterparty strength, and it lets an insurer write more where a weakened rival has to retrench after a catastrophe.
Operational Efficiency
Not measurable
· 12% of the moat score
The expense ratio — what it costs to acquire and administer a policy — is the half of the combined ratio management fully controls. Every point of expense advantage can be handed back as price while still leaving the same underwriting profit, which makes a lean insurer structurally hard to compete against in commodity lines.
Scale & Diversification
Not measurable
· 8% of the moat score
Diversification is a real economic advantage in insurance rather than a portfolio preference: risks spread across perils, geographies and lines are less likely to arrive at once, so the same capital supports more premium. Scale also buys reinsurance on better terms and smooths the earnings volatility a single-peril insurer cannot avoid.
