Government cites Middle East oil shock
The latest move deepens an earlier diesel intervention this month. The previous Royal Gazette order, published on April 8, imposed a 2-baht-per-litre cut in ex-refinery diesel prices from April 9, meaning the new measure significantly expands that relief effort.
Thai officials have tied the intervention to the continuing energy shock caused by conflict in the Middle East, which has pushed the government to use emergency powers to curb refinery-level diesel prices and reduce pressure on consumers and businesses.
