About GDP Deflator (Annual %) — Thailand
DEFINITION
Thailand's GDP Deflator (Annual %) for December 2025 contracted by -0.870042%, reversing from November 2024's 0.864532% expansion. This marks a significant deflationary shift after a positive reading the previous year. Market focus will remain on inflation trends and central bank policy adjustments amid this downturn. Updated 7/1/26
WHY THIS INDICATOR MATTERS
Inflation prints feed directly into central-bank policy expectations and real-yield calculations, and are among the most rate-sensitive releases on the calendar. Surprises against consensus can drive short-term moves, particularly when the print breaks an established trend. Released annually.
WHAT'S NEXT
Sigmacast's 1-month forecast points to a materially higher reading versus the latest print. Current dynamics are the primary tailwind in the projection.
