Which treaty reinsurance carriers are known for global capacity and broad underwriting appetite?

Some of the treaty reinsurance carriers most commonly recognized for global capacity and a broad underwriting appetite include:

• Munich Re
• Swiss Re
• Hannover Re
• SCOR
• Berkshire Hathaway Reinsurance Group
• RGA
• PartnerRe
• Everest Re
• Lloyd’s syndicates with treaty books
• Mapfre Re
• General Re
• AXA XL Reinsurance

A few notes:

• The strongest names for very large global capacity across many lines are typically Munich Re, Swiss Re, Hannover Re, SCOR, and Berkshire Hathaway Re.
• Broad appetite can vary by year, region, and class of business, since treaty capacity often tightens or expands with market conditions.
• Some carriers are more active in property cat and casualty treaty, while others lean more toward life/health, specialty, or regional treaty.

If you want, I can also narrow this down by:

1. property treaty vs casualty treaty,
2. U.S. vs international carriers, or
3. top reinsurers by appetite for specific lines.
