The Story
On October 16, 2026, Travelers, one of the largest U.S. property and casualty insurers, reported results for its third quarter ended September 30. Net income rose 2% to $1.917 billion, or $9.04 per diluted share, up from $8.24 a year earlier. Core income, which leaves out realized investment gains and losses, rose 4% to $1.947 billion, or $9.18 per share.
The top line barely moved. Net written premiums, the insurance Travelers sold in the quarter after reinsurance, were $11.48 billion, about flat with last year, partly because it sold its Canadian business earlier in 2026. Excluding that sale, premiums grew 2%.
So where did the profit come from? Two places. First, underwriting. For every $100 of premiums Travelers earned, it spent about $57.90 on claims and the cost of handling them and about $28.90 on commissions and other expenses. Add those together and you get the combined ratio: 86.8%, improved from 87.3% a year ago. That left a pre-tax underwriting gain of $1.432 billion on $11.1 billion of earned premiums.
Second, investing. Travelers collects premiums up front and pays many claims months or years later, so it holds a large portfolio, $100.6 billion of invested assets at quarter-end. That portfolio produced a record $1.098 billion of pre-tax net investment income, up 6%, helped by higher yields and more assets.
The quarter wasn’t smooth. Catastrophe losses, mostly from wind and hail storms, rose to $538 million from $402 million, adding 4.8 points to the combined ratio. Offsetting that, Travelers lowered its estimates for claims from prior years by a net $234 million, even after adding $295 million to asbestos reserves. Investing.com reported shares down about 4.4% in premarket trading, pointing to the higher catastrophe losses.
The Lesson
The combined ratio is the one number that tells you whether an insurer makes money on its insurance. It adds the loss ratio (claims and claim-handling costs divided by earned premiums) to the expense ratio (commissions, salaries, and overhead divided by earned premiums). Below 100% generally means the insurer kept something from every premium dollar before investing a cent. Above 100% means it paid out more than it took in on policies and needs investment income to cover the gap.
The second engine is float: money customers pay in advance that the insurer gets to invest until claims come due. Travelers’ release doesn’t use that word, but the numbers show it at work. An underwriting gain of $1.432 billion plus investment income of $1.098 billion, minus $127 million of other expenses including interest, equals $2.403 billion of pre-tax core income. Investment income alone equaled about 46% of that total. An insurer that runs a combined ratio under 100% is, in effect, being paid to hold other people’s money.
The ratio also deserves a second look, because claims are estimates. Travelers reports an “underlying” combined ratio of 84.1% that removes catastrophes and changes to prior-year reserves. This quarter the two moved in opposite directions: the reported ratio improved 0.5 points, while the underlying ratio worsened 0.2 points. Reserve releases did the improving. Neither number is the “real” one. Read them together.
How to Use It
1. Find the combined ratio first. Under 100% generally means an underwriting profit; over 100% means the insurer is leaning on its investments. Travelers’ 86.8% left about 13 cents of each premium dollar before any investment income.
2. Split profit into its two engines. Put the underwriting gain next to net investment income. The more profit comes from investments, the more exposed the company is when interest rates fall.
3. Separate the weather and the reserves. Find catastrophe losses and prior-year reserve changes, then check the underlying ratio. A better headline ratio built on reserve releases is not a better business.
4. Watch the premium line. A better ratio on flat premiums is margin, not growth. Ask whether premium growth is coming from higher prices, new customers, or neither.
5. Use it in your own work. Any business that gets paid before it delivers, like subscriptions, deposits, or prepaid services, has float. Price so the core service makes money on its own, and treat interest on customer cash as a bonus, not the plan.
