Petrol prices in Pakistan could increase by up to Rs1.54 per litre from September 16, while high-speed diesel may rise by Rs4.79, industry sources said on Saturday.

Preliminary calculations also indicate kerosene could climb by Rs3.06 and light diesel by Rs3.68 per litre.

The Oil and Gas Regulatory Authority (OGRA) will send its final working to the Petroleum Division on 15 September.

The Petroleum Division and Ministry of Finance will then forward the proposal, including levies and taxes, to the prime minister for approval.

New rates will take effect after the prime minister’s consent.

On September 1, the federal government announced a Rs3 per litre reduction in the price of high-speed diesel (HSD), while keeping the price of petrol unchanged for another fortnight.

According to an official notification issued by the Finance Division, the revised petroleum prices came into effect at midnight (September 1, 2025) and will remain applicable for the next 15 days.

Following the adjustment, the price of HSD has been brought down from Rs272.99 to Rs269.99 per litre. The price of petrol, however, remains unchanged at Rs264.61 per litre.

The changes follow the government's routine fortnightly review of international oil prices and exchange rate movements.

Other petroleum products also saw slight reductions. The price of superior kerosene oil was lowered by Rs1.46, from Rs178.27 to Rs176.81 per litre.

Similarly, light diesel oil dropped by Rs2.40, now priced at Rs159.76 from the earlier Rs162.37 per litre.

The revised pricing comes amid global crude benchmarks, where motor gasoline premiums currently stand at $6.37 per barrel and HSD premiums at $3.20 per barrel.

Domestic pricing also factors in the Inland Freight Equalisation Margin (IFEM)—Rs8.05 per litre for petrol and Rs6.20 for diesel—as well as the Petroleum Levy (PL) and the Climate Support Levy (CSL), components that significantly influence retail fuel costs.

This is the second consecutive fortnight during which the government has kept petrol prices unchanged while reducing the prices of other petroleum products by up to Rs12 per litre.

On August 15, the federal government cut the price of high-speed diesel (HSD) by Rs12.84 per litre. Similarly, the prices of superior kerosene oil and light diesel oil were also reduced by Rs7.19 and Rs8.20 per litre, respectively.
