This edition of Milliman’s 'South East Asia in focus', a newsletter for the health insurance market, covers developments from the first half of 2025. The core of the report includes market performance for Hong Kong, Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam. Market surveys for each region include information on the medical claims inflation rate, repricing frequency, and deductible plans.

Emerging themes across the region include:

• Reintroduction and enforcement of co-payments, deductibles, and benefit limits to instill discipline in claims behaviour.
• Greater collaboration among governments, insurers, providers, and regulators to design fairer, more transparent, and more sustainable provider reimbursement systems.
• Rising importance of data and cost transparency.
• Expansion of insurer-led provider networks.
