Thailand’s gross domestic product (GDP) contracted in the second quarter of 2026, declining 0.20% quarter-on-quarter after posting modest growth earlier in the year. The latest data, updated on 17 August 2026, marks a reversal from the first quarter of 2026, when GDP expanded by 0.70% compared with the previous three months.
On a quarter-over-quarter basis, the new reading underscores a weakening in short-term momentum. While the first quarter’s 0.70% increase reflected an improving trend versus the quarter before it, the move into negative territory in the second quarter signals growing pressure on Thailand’s economic activity over the spring period.
The shift from positive to negative quarterly growth will likely sharpen investor and policymaker focus on near-term drivers of demand and the sustainability of Thailand’s recovery path. Market participants will be watching upcoming data releases and policy responses for clues on whether the second-quarter contraction proves temporary or the start of a more prolonged slowdown.
