The moat

A commercial buyer of property and casualty insurance is not shopping the way a household shops for auto coverage. A logistics operator insuring cargo, a mid-sized bank buying directors and officers cover, a reinsurance broker placing a treaty for a regional insurer, they buy capacity from carriers rated highly enough to satisfy their own counterparties, at terms the underwriter will actually pay on when a loss hits. What they lose by leaving a disciplined carrier for a cheaper one is not obvious at renewal; it shows up two years later when a claim gets contested or a soft-cycle rival cannot pay. So the demand for a Fairfax subsidiary (Odyssey, Allied World, Crum & Forster, Brit, Zenith, Northbridge) is really demand for capacity that keeps showing up cycle after cycle.

The moat has two pieces that only work when both are intact. The first is underwriting discipline: writing policies only when the premium plus expected investment income exceeds the expected claims, so that the pool of money held between premium and claim, the *float*, costs less than zero to hold. The consolidated undiscounted combined ratio of the property and casualty insurance and reinsurance operations was 93.0%, producing record underwriting profit of $1,816.6 million in 2025. A ratio below 100 means every dollar of premium produced pays claims and expenses with change left over; Fairfax has been running about seven cents of change per dollar. The second piece is what Watsa's team does with the float. Fairfax manages a consolidated investment portfolio exceeding $70 billion. That portfolio, funded largely by float and shareholder equity, threw off net gains on investments of $3.2 billion and record interest and dividend income of $2.6 billion in 2025.

Classify the moat honestly. This is a regulatory-franchise archetype at the base (you cannot start a global reinsurer next Tuesday, the licenses and ratings take decades), with an unusually strong *underwriting-plus-float* execution layer on top that most licensed peers do not match. The secondary moat is decentralized underwriting culture: 26 separately run subsidiaries where the CEO stays close to loss ratios. V. Prem Watsa has been the Chairman of the Board of Directors and Chief Executive Officer since 1985, and is Vice Chairman of Hamblin Watsa Investment Counsel Ltd. since 2019, after serving as Vice President since 1984. What the moat produces is not pricing power (P&C rates cycle with capacity, not with brand); it produces per-share book-value compounding. Book value per basic share increased 22.7% per year over the three years ending December 31, 2025, and 20.9% per year over five years.
