Key drivers 2025-2026
Demand
Thai HNW family spending
Thai ultra-high-net-worth family spending on international education has proven resilient through economic cycles. Harrow's $26,087+ tier targets the top 0.1% of Thai household incomes — a narrow but stable demand pool.
Competition
New British school entrants
Rugby School Thailand (2017) and Wellington College Bangkok (announced) expand the ultra-premium British tier. Competitive intensity at $23,188+ is rising as UK school brands expand Asian franchise networks.
Regulation
OPEC and MoE licensing
Thailand's Office of the Private Education Commission (OPEC) governs international school licensing, curriculum approval, and teacher-qualification requirements. Regulatory changes affecting foreign-teacher quotas or fee ceilings would affect cost structure.
