Thailand Faces Key Year for Credit Rating Review

Thailand is entering a decisive year for its sovereign credit rating, with three major agencies set to assess the country’s economic outlook in 2026. The reviews carry significant financial implications after two agencies downgraded Thailand’s outlook to “negative” last year. The outcome could affect the country’s borrowing costs and investor confidence.

In 2025, both Moody’s and Fitch Ratings revised Thailand’s outlook to “negative”, while S&P Global Ratings maintained a “stable” outlook. Thailand currently holds ratings of Baa1 and BBB+. As a result, 2026 is viewed as pivotal in determining whether the country can avoid a downgrade.

Jindarat Viriyataveekul, Director of the Public Debt Management Office (PDMO), said the assessment timeline begins with Moody’s, which is expected to announce its decision between March and April 2026. The decision could be delayed until September to allow for clarity from the new government. Fitch and S&P are scheduled to follow with their assessments in the second half of the year, between August and September.

According to the PDMO, five key factors will determine Thailand’s credit standing. Political stability and continuity of government policy are considered the most important elements for foreign investors, as they ensure economic momentum is maintained after the election. Medium-term fiscal discipline is also critical, with the government aiming to reduce the budget deficit from over 4% to 3% of GDP by 2030 to control public debt.

GDP growth remains another central measure, particularly amid global economic volatility. Weaker-than-expected growth could become a vulnerability and increase the risk of a downgrade. In addition, Thailand’s ageing population presents structural challenges that may affect competitiveness and increase welfare burdens, requiring a clear and credible response.

The development of targeted “New S-Curve” industries and the expansion of financial instruments such as Blue Bonds and Green Bonds are also seen as essential to attracting high-quality investment. Jindarat emphasised that progress in economic structural reform and a clear deficit-reduction strategy would be key to restoring Thailand’s outlook to stable if performance aligns with government plans.

The Nation reported that the decisions by the three agencies throughout 2026 will determine whether Thailand can maintain its current rating levels or face further pressure. The government’s ability to demonstrate policy continuity, fiscal control and economic resilience will be closely scrutinised by global investors.
