Swiss Re's sigma 1/2026 puts 2025 Asia-Pacific weather-related economic losses at $203 billion, against insured losses of $77 billion. The protection gap was sixty-two percent. That is the share of weather damage no policy covered. The Philippine typhoon sequence between August and October 2025 drove $28 billion in economic damage; insurers covered $3.4 billion of it, eleven percent. Swiss Re holds $14.8 billion of non-life reinsurance premium in APAC, making it both the continent's largest reinsurer and the firm whose sigma desk produced the protection-gap reference that July 1 treaty negotiations will use.

July 1 is the primary renewal date. That is when Munich Re, Hannover Re, and Lloyd's syndicates reprice the property-catastrophe treaties (the contracts that cap how much of a major storm loss a local insurer absorbs before reinsurance kicks in). After three consecutive years of APAC weather losses above $150 billion, broker guidance from Aon and Guy Carpenter places cat-program rate increases at fourteen to twenty-two percent for portfolios still absorbing 2025 losses. Munich Re's APAC non-life premium book runs to $11.2 billion; its NatCat research team, which published its own $197 billion APAC loss figure in January, provides the actuarial assumptions underwriters use when setting July 1 pricing. The Philippine Insurance Commission told the Senate Committee on Banks on 5 June that a further twenty-percent increase would push gross premium beyond the affordability threshold for twelve provincial governments that buy catastrophe cover on behalf of their populations. Aon's Reinsurance Market Outlook for the July renewal cycle is scheduled for the week of 22 June 2026.
