The Indian government has revised its windfall taxes on fuel exports, increasing duties on diesel and aviation turbine fuel while lowering the levy on petrol, with these changes taking effect on July 16 as part of its fortnightly review to stabilize domestic supply amid volatile global oil prices and geopolitical tensions. Specifically, diesel export duties rise to 15.5 rupees per litre and ATF duties to 14.5 rupees per litre, up from 8.5 and 7.5 rupees respectively, while petrol export duties are cut to 2.5 rupees per litre from 4 rupees. The adjustments come as global oil markets, boosted by U.S.-Iran hostilities, push prices higher and prompt the government to balance domestic availability and fiscal objectives. The policy shift is designed to curb export surges and secure fuel availability for domestic consumption, reflecting the government’s ongoing use of windfall taxes during times of price volatility. Market observers note that these changes affect refiners and exporters by narrowing profit margins while supporting domestic supply, with analysts also watching how Brent crude levels influence future revisions.
