Thailand’s core Consumer Price Index (CPI) rose to 1.58% year-over-year in October 2026, edging up from 1.50% in September, according to data updated on 6 November 2026. The figure reflects underlying inflationary pressures in the economy, excluding volatile items, and is based on a comparison of October prices with those of October a year earlier.
The October reading marks a modest acceleration from the previous month, when core CPI was measured against September of the prior year. While the increase is slight, it indicates a continued, gradual firming in core inflation rather than a reversal or slowdown. For policymakers and market participants, the latest data will likely be read as a sign that underlying price growth remains contained but is trending gently higher on a year-over-year basis.
Because the core CPI strips out more volatile components, the 1.58% print provides a clearer view of Thailand’s longer-term inflation dynamics as of October. Investors and analysts will watch subsequent releases closely to see whether this uptick consolidates into a more pronounced trend or remains within a narrow range around current levels.
