Higher diesel levy absorbs part of global oil price decline as government prioritizes revenue collection ahead of budget
The government has retained a substantial share of the benefit from lower international oil prices by raising the petroleum levy on high-speed diesel (HSD), limiting the relief passed on to consumers despite a sharp decline in global fuel costs.
Under the latest fortnightly fuel price adjustment announced on May 29, 2026, the price of high-speed diesel was reduced by Rs22 per litre to Rs380.78 per litre for the period from May 30 to June 5.

Market analysts said the reduction could have been significantly larger had the government fully transferred the impact of falling international petroleum prices to domestic consumers.
According to data compiled by Arif Habib Limited, the ex-refinery price of high-speed diesel declined by Rs33.92 per litre following a drop in international oil prices. Meanwhile, the Inland Freight Equalization Margin (IFEM) increased by Rs0.99 per litre.
The largest adjustment came through the petroleum levy, which was increased by Rs10.93 per litre from Rs58 per litre to Rs68.93 per litre. The levy increase effectively absorbed a significant portion of the potential reduction in diesel prices that could otherwise have been passed on to consumers.
Analysts noted that while consumers received some relief through the Rs22 per litre cut, the higher levy enabled the government to secure additional revenue at a time when fiscal pressures remain elevated ahead of the federal budget for fiscal year 2026-27.
The petroleum levy remains one of the federal government’s most important sources of revenue because its proceeds are retained entirely by the federal government and are not distributed among the provinces. As a result, policymakers have increasingly relied on the levy to strengthen revenue collection and support budgetary objectives.
Economists often classify the levy as an indirect tax that contributes to inflationary pressures across the economy by increasing transportation, logistics, agricultural and industrial costs, which are eventually reflected in consumer prices.
The adjustment comes amid easing geopolitical tensions in the Middle East, which have contributed to lower international crude oil and refined fuel prices. The decline in global energy markets had raised expectations among consumers and businesses that domestic fuel prices would fall more sharply.
In contrast to diesel, petrol was treated differently in the latest pricing review. The ex-refinery price of petrol declined by Rs13.11 per litre, while IFEM increased by Rs1.94 per litre. At the same time, the government reduced the petroleum levy on petrol by Rs10.83 per litre, allowing a larger share of the international price decline to be reflected in domestic retail prices.
Despite the reduction in diesel prices, analysts said the government’s decision to raise the levy highlights its focus on fiscal consolidation and revenue generation. They noted that a considerable portion of the savings resulting from lower international oil prices was retained by the government rather than fully passed on to consumers.
The move is expected to reignite debate over the balance between revenue mobilization and inflation management, particularly as households, transporters, farmers and businesses continue to face elevated energy and operating costs.
