# Breaking down the government's plan to use Adjusted GRM rules to extract refinery profits and pressure PTT dividends to bolster state coffers

> Thailand plans to use an adjusted refinery-margin formula, deducting specified extra costs, and treat net margins above 2.40 baht per litre as excess profit for energy-price relief. Refiners have already contributed more than 30 billion baht toward holding down diesel prices, and the government is seeking higher dividends from state-owned PTT to add revenue to public finances.

## Why it matters

The policy directs refinery margins toward consumer energy-price support, including diesel, which may constrain fuel pricing and refinery returns. Lower diesel costs could ease feed production and transport expenses, although the report does not quantify a specific commodity-market impact.
