Pulse Analysis

Thailand’s equity market has witnessed a steady climb in foreign ownership over the past five years, culminating in a record 6.11 trillion baht of holdings in January 2026. This figure translates to 37.1% of the market’s total capitalisation, up from just 26.5% in December 2021. The upward trajectory aligns with a series of post‑election reforms that have reduced political uncertainty, while the Bank of Thailand’s accommodative monetary stance has kept financing costs low. Moreover, Thai stocks trade at price‑to‑earnings multiples that are modest compared with peers in Southeast Asia, making them attractive to global portfolio managers seeking value and diversification.

The surge in foreign participation is not limited to share ownership; it also reshapes trading dynamics. In 2025, overseas investors generated 52.8% of the market’s total trading value, a share that has exceeded half for three consecutive years. Even as they recorded a net sell of 107 billion baht in equities, they simultaneously purchased 87.1 billion baht of non‑voting depository receipts, preserving exposure to Thai corporate earnings. This dual‑track activity has amplified liquidity, with foreign traders turning over their holdings 1.83 times on average, thereby narrowing bid‑ask spreads and enhancing price discovery for both large‑cap and mid‑cap issuers.

Looking ahead, the continued rise in foreign stakes could reinforce Thailand’s ability to attract new listings and lower capital‑raising costs for existing companies. However, the market remains vulnerable to shifts in global risk appetite, especially if U.S. interest rates rise or regional geopolitical tensions flare. Policymakers will need to sustain the current blend of political stability and monetary flexibility while advancing corporate‑governance reforms to keep foreign confidence high. For investors, the combination of solid earnings growth, relative valuation discounts, and robust liquidity presents a compelling case for allocating a larger portion of Asia‑Pacific equity portfolios to Thailand.
