As of September 18, 2025, several regions have announced adjustments to petrol and diesel prices. In Peninsular Malaysia, the retail prices of RON97 petrol and diesel have seen a slight increase of 3 sen per liter. This adjustment, effective today, brings the price of RON97 to RM3.21 per liter and diesel to RM2.93 per liter. However, the price of RON95 remains unchanged at RM2.05 per liter. Meanwhile, in Sabah, Sarawak, and Labuan, the price of diesel remains steady at RM2.15 per liter.

These price adjustments are a result of recent increases in global oil prices. The Ministry of Finance has stated that it will continue to monitor global oil trends and adjust prices as necessary to ensure price stability and protect public welfare. The government is committed to taking appropriate measures to safeguard the well-being of the people.

In India, fuel prices are revised daily at 6 a.m. and are influenced by several factors, including the cost of crude oil, OMC costs, value-added tax (VAT), excise duty, and dealer commission. These factors contribute to price differences across states. As of September 18, 2025, the diesel price in Delhi stands at ₹87.67 per liter, which remained unchanged from the previous day. Over the past 10 days, diesel prices in Delhi have fluctuated between ₹87.61 and ₹87.67.

Changes in diesel prices can have a cascading effect on the economy. Rising diesel prices impact transportation costs, which can put upward pressure on commodity prices. To mitigate inflationary pressures, the Reserve Bank of India (RBI) may adjust interest rates, leading to a higher cost of borrowing.

Consumers can stay informed about fuel prices through various online resources, including the websites of fuel companies and news outlets. It's also worth noting the increasing interest in electric vehicles, which could potentially impact petrol and diesel prices in the future.
