Panelist insight: Commenting on the outlook, Enrico Tanuwidjaja and Sathit Talaengsatya, analysts at United Overseas Bank, stated:
“We [revised downward our] forecast for Thailand’s headline CPI […] The downgrade reflects: (i) a weaker-than-expected Sep outturn (headline -0.72% y/y; core +0.65% y/y), (ii) official guidance that inflation will hover near zero into 4Q—helped by lower Dubai crude, the FT [fuel tariff] reduction to 0.1572 baht/unit that pulls the electricity tariff to 3.94 baht/unit, abundant fresh-produce supply, and ongoing retail promotions—and (iii) a subdued growth outlook. These forces, which prolong supply- and policy-driven disinflation, keep underlying pressures contained into early 2026. We then assume a modest positive print in 2027 as energy base effects fade, cost-of-living measures lapse, and core gradually refirms from current low levels.”
