FX.co ★ Thailand’s Q1 2026 GDP Growth Edges Up to 2.8% Year-on-Year

Thailand’s economy gained modest momentum at the start of 2026, with gross domestic product (GDP) expanding by 2.8% year-on-year in the first quarter. The latest figure, updated on 18 May 2026, marks a slight improvement from the 2.5% year-on-year growth recorded in the fourth quarter of 2025.

The data are presented on a year-over-year basis, meaning the current 2.8% growth rate compares economic output in the first quarter of 2026 with the same quarter a year earlier, while the previous 2.5% reflected a comparison of the fourth quarter of 2025 with the fourth quarter a year earlier. The uptick suggests a gradual strengthening in Thailand’s economic performance as it moves further into 2026, though the pace of expansion remains relatively moderate by historical standards.
