Thailand's May CPI rose 2.79 pct YoY, down from 2.89 pct in April, the commerce ministry said on Friday. The slowdown, still within the Bank of Thailand's target range, eases pressure on the BOT to tighten policy. The BOT has described price gains as transitory and said tightening has limited effect on supply-driven shocks; Governor Vitai Ratanakorn said the current policy rate remains appropriate. The commerce ministry expects June inflation around 3 pct and to remain above 3 pct in H2.
