Thailand's healthcare expenditure is growing faster (7.6% annually, 2000–2023) than GDP (5.8%), raising the health-spending-to-GDP ratio from 3.08% to 4.54%. With an aging population (60+ rising from 17% to 29% by 2032) and the state covering ~78% of costs, budget pressures will mount after 2030. Without cost controls, welfare spending will squeeze investment; alternatives include raising state revenue, overhauling tax structure, improving efficiency, or restructuring benefit allocation. The social security system also faces strain, with benefit payouts growing 9% annually against only 3% contribution growth.
