Assured Guaranty

We see a durable moat built primarily on efficient scale, ratings-driven brand trust, and underwriting know-how. Efficient scale: the U.S. municipal insurance market is served mainly by two players (Assured and BAM).

Assured insured about 58% of U.S. primary insured par in 2025 and remained the market leader in 1H 2026, reflecting entrenched distribution, issuer relationships, and large-case execution expertise.

Intangible assets: AA insurer financial strength ratings across core subsidiaries with stable outlook, and S&P highlighted capital adequacy above its AAA stress level, which confers credibility with issuers and investors and supports deal flow at attractive terms.

Switching costs: while issuers can select insurers at origination, the end-investor preference for wrapped bonds from a highly rated guarantor plus the policy’s life-of-bond permanence create meaningful stickiness and repeat business, though this is weaker than software-like switching costs.

Cost advantages: scale, data, and workout expertise help Assured price idiosyncratic risks and manage legacy exposures (for example, Puerto Rico) better than smaller peers. Network effects: limited. Ratings and reputation matter more than user counts.

Moat durability risks include: lower insurance penetration if spreads compress, potential competitive responses from BAM, rating-model changes, and legal outcomes around PREPA that could affect perceived risk. Overall, multiple moat vectors exist, led by efficient scale and ratings brand.
