2026 medical trend projections
What these numbers are — and are not
Each panel below is a survey projection for 2026 published by its named firm. They describe the medical cost trend insurers expect, before plan changes (gross) or after them (net). They are not observed 2026 inflation, not consumer price inflation, not a hospital bill and not your premium renewal increase. The three firms use different methods and samples, so their figures are shown side by side — never averaged.
Survey projection · October 2025
WTW — 2026 Global Medical Trends Survey
Methodology & scope
Survey of health insurers and intermediaries asking for the medical cost trend they project for 2026. "Gross" means before any plan-design changes or cost-sharing adjustments. These are projections, not observed 2026 inflation, not consumer prices, and not any individual premium renewal.
Regional figures are survey-wide aggregates. WTW APAC 14.0% is not the medical inflation rate of any single Asian country.
Survey projection · 2026 edition
Aon — 2026 Medical Trend Rates — Asia Pacific
Methodology & scope
Aon survey of insurers and actuarial teams projecting 2026 medical trend in Asia-Pacific. "Net" means after expected plan-design and cost-management effects. Different method and sample from WTW — the two are not directly comparable and must not be averaged.
Asia-Pacific aggregate only; not a per-country rate.
Survey projection · 2026 edition
Mercer Marsh Benefits — Health Trends Report — Asia
Methodology & scope
Mercer Marsh Benefits insurer survey projecting 2026 medical trend for Asia. Uses a different questionnaire and sample from WTW and Aon, so the figure sits alongside them, not blended with them.
Asia aggregate only; not a per-country rate.
