Swiss Re's sigma No. 2/2025 puts APAC natural catastrophe economic losses at $94 billion for 2025, against $38 billion of insured losses. The protection gap, the share of weather loss that no insurance covers, ran fifty-nine percent. Swiss Re carried an estimated $4.3 billion in net catastrophe reinsurance premium from APAC that year. The firm naming the gap prices the renewal.

The July 1 mid-year reinsurance cycle turns that number into treaty rates. Two above-average Western Pacific typhoon seasons -- 2024 and 2025 each produced more than twenty-five named storms -- have pushed cat modelers to revise South China Sea corridor annual average loss estimates upward by twelve to eighteen percent. Cover is thin. Philippine non-life insurance penetration sat at 1.6 percent of GDP in 2025, second-lowest in APAC by Insurance Commission Manila data, meaning local cedants arrive at the July renewal with little room to absorb higher rates before retaining more tail risk themselves. The Philippines Bureau of the Treasury closes its 2026 parametric disaster facility tender on June 30, the last bid window before July renewal terms lock.
