Thailand's inflation turned positive in March after 12 consecutive months of declines, signaling the end of its deflationary streak. Consumer prices fell just 0.08% year-over-year, a sharp slowdown from February's 0.88% drop, according to Commerce Ministry data. This acceleration underscores the economy's vulnerability to energy shocks, as over half of Thailand's oil imports originate from the volatile Middle East, much of it shipped through the Strait of Hormuz. March's monthly rise of 0.6% further highlights the impact, with core inflation edging up 0.57%.

The Commerce Ministry now forecasts 2025 inflation at 1.5%-2.5%, up from its previous -1% range, citing higher oil prices. The Bank of Thailand has already cut rates by 150 basis points since late 2024, pushing the benchmark rate to 1% in February. While officials expect inflation to return to its 1%-3% target range earlier than expected, economists see it remaining contained within the band. The central bank has stressed the current pickup is supply-driven, limiting the effectiveness of further monetary tightening.

Governor Vitai Ratanakorn stated there's no need for drastic policy changes, as rate hikes would do little against energy-driven inflation while risking demand harm. Assistant Governor Chai-Anant signaled a wait-and-see approach, with rate cuts unlikely to offset the oil shock. March's inflation reading marks a critical turning point for Thailand's economic policy and market expectations.
