North American insurers and reinsurers just posted their strongest underwriting results in recent memory, with operating returns climbing sharply through the first half of 2026.
Fitch Ratings pinned the surge on two tailwinds: a dramatic drop in catastrophe payouts plus rising investment income. The sector’s operating return on common equity hit 11.2%, a meaningful jump from 8.9% recorded during the same stretch last year. Nearly every insurance line delivered double-digit returns.
Catastrophe losses played the starring role in this turnaround. Weather-related claims added only 3.8 percentage points to the industry’s combined ratio in the first six months of 2026. That figure stood at 8.0 points a year prior. Consequently, the aggregate combined ratio improved to 87.9% from 91.8%, signaling healthier underwriting discipline across North American markets.
Reserve releases supplied another earnings boost. Favorable development shaved 3.0 percentage points off the combined ratio, compared with a 1.9-point benefit in the first half of 2025. Workers’ compensation reserves continued their long-running pattern of favorable emergence. Personal auto claims also came in below initial severity projections, giving insurers room to release prior reserves.
Those reserve adjustments lowered underwriting expenses and reinforced operating income, compounding the financial lift from milder catastrophe activity.
Meanwhile, carriers strengthened balance sheets even as they returned substantially more cash to shareholders. Common equity grew 4% during the six-month period, buoyed by positive net earnings. The capital build occurred despite elevated shareholder distributions, reflecting the sector’s growing confidence in its earnings durability.
The trajectory leaves North American reinsurers well positioned heading into the second half of 2026, though the usual wildcard remains: hurricane season and its potential to reverse these gains.
