Chubb posted record nine-month core operating income of $8.6 billion, but the quarter underneath that figure tells a more complicated story. The world’s largest publicly traded commercial insurer is walking away from a growing portion of the North American large account market rather than write business at prices it considers inadequate. Middle market and small commercial grew 0.8% in the quarter, with Chubb continuing to write that segment while pulling back from large account and E&S business it considers inadequately priced.
North America commercial P&C net premiums written fell 2.7% in Q3 2026 to $5.51 billion. The segment accounts for 36% of Chubb’s total net premiums written, making it the single largest slice of the book. Major accounts, retail and E&S wholesale, the segment where Chubb is a dominant force for large commercial placements, fell 5% to $3.21 billion. That decline is now the third consecutive quarter in which North America commercial has contracted or grown only marginally, after a 2.3% fall in Q2 and a modest 2.3% gain in Q1, where large account property was already dropping sharply.
The combined ratio for North America commercial deteriorated to 86.3% in Q3, from 81.5% a year earlier, driven in part by $705 million in pre-tax catastrophe losses across the group. The figure is more than double the $285 million Chubb absorbed in the same quarter of 2025, when the segment posted underwriting income that was, as covered in prior results reporting, a record for the company.
Chubb chairman and CEO Evan Greenberg was clear about what is driving the contraction. The “substantial majority” of Chubb’s underwriting businesses grew in the quarter, he said, with the balance “flat or purposely shrinking due to inadequate pricing or terms.” He added that he expects North America commercial growth to improve in future quarters, confirming that the current discipline comes at the cost of near-term volume.
The pricing environment that prompted those non-renewal actions has been building across the year. In earlier earnings calls, Greenberg described market pricing on large account and E&S property business Chubb declined as down between 30% and 40%. He also singled out the London wholesale market as “highly competitive, and not only in property,” noting that US casualty business is actively flowing to London despite no shortage of domestic capacity.
Financial lines have also remained soft. In Q3, the current accident year combined ratio excluding catastrophe losses for North America commercial moved from 80.8% to 82.1%, a 1.3 point deterioration that signals underlying margin pressure beyond the CAT impact.
That combination of declining volumes, a widening combined ratio, and management commentary on pricing that does not justify the risk gives brokers placing large commercial, E&S, or financial lines business with Chubb a direct read on where the carrier’s appetite currently sits. Chubb is not retreating from those segments permanently, but it is making clear it will not defend premium volume at the expense of return.
The contrast with Overseas General is pronounced. International P&C net premiums written grew 6.7% to $3.94 billion, with Latin America up 11.7%, Asia up 7.5% and Europe up 6.8%. International commercial grew 6.3% and consumer lines grew 7.2%. Life insurance income grew 11.4% in constant dollar terms, with international life premiums and deposits up 15.7%. Adjusted net investment income hit a record $1.89 billion, up 6.3%, supported by rising interest rates that Greenberg has signalled will become a more significant earnings contributor over the medium term.
The nine-month picture bears that out. Year-to-date P&C underwriting income of $5.79 billion is up 33.7% from 2025, while core operating income of $8.6 billion is up 21%. Those figures are what enable Chubb to absorb the deliberate contraction in North America commercial without headline earnings deteriorating. That position is what Greenberg has been telegraphing to analysts since at least Q3 2025, when he argued that Chubb’s diversification allows it to grow earnings through a softening cycle even as large account US volumes compress.
Chubb also disclosed that KKR agreed during the quarter to sell USI Insurance Services to Aon through Strategic Holdings, the holding company vehicle in which Chubb co-invested. Chubb’s $740 million stake is expected to generate a realized gain of $460 million when the transaction closes in Q4 2026.
