A Quiet Catastrophe Half-Year Took Reinsurers' Combined Ratio to 86.1% — and Started Cutting Prices

Reinsurance is priced off losses that have already happened. The first half of 2026 produced unusually few of them, and the consequences are now visible in two places: reinsurers' results, which improved sharply, and reinsurance prices, which are falling.

The loss side

Swiss Re Institute puts global insured losses from natural catastrophes at about $42 billion for the first half, the lowest first-half figure since 2020 and well under its long-term trend estimate of $66 billion. Total economic losses were roughly $100 billion, meaning insurance covered about 42% of the damage — above the 30-year average share of 33%.

• Severe convective storms: about $28 billion, the lowest since 2021 on an inflation-adjusted basis and below a trend estimate of $36 billion
• Storm activity itself ran about 20% above average; few high-impact events struck densely populated areas
• Winter storms in the United States and Europe were a secondary driver
• A Venezuelan earthquake sequence on June 24 caused about $20 billion of economic damage — Latin America's costliest since the 2010 Chile earthquake — but little insured loss, because insurance penetration there is low

The result side

Fitch Ratings tracked 18 non-life reinsurers through the half. Their aggregate combined ratio was 86.1%, against 92.7% a year earlier. The combined ratio is claims plus expenses expressed as a percentage of premium earned: below 100 means the underwriting itself made money, before any investment return. Catastrophe losses contributed 3.5 percentage points of that ratio, against 10.9 points in the first half of 2025 — which accounts for essentially the whole improvement.

• Net premiums written: down 6%, to $73.73 billion
• Combined ratio: 86.1%, from 92.7%
• Catastrophe load: 3.5 points, from 10.9
• Net income return on equity: 18.2%

Writing 6% less premium and earning a higher return on equity is the signature of a softening market in its early stage: reinsurers are declining business at the new prices rather than chasing volume.

The price consequence

Property-catastrophe rates fell by double-digit percentages at the mid-year 2026 renewals. Fitch expects further softening at the January 2027 renewals absent a large-scale hurricane or other loss event, with growing flexibility in terms and conditions. Retentions and attachment points — the level of loss at which a reinsurer's cover begins — have so far remained largely unchanged, which means the softening is showing up in price rather than in the structure of the cover.

The long-term trend remains upward, driven by expanding exposure, rising asset values and changing vulnerability.

Why it matters

The reinsurance cycle is one of the few places in finance where price responds to a physical variable with a short lag. A calm half-year lowers the cost of transferring catastrophe risk; an active one raises it. That cost sits somewhere upstream of every property insurance premium, which is why the combined ratio of eighteen companies most people have never heard of is worth reading.
