Fuel prices today: Latest petrol, diesel, CNG rates across major cities on May 20

Petrol and diesel prices remained unchanged across the country on Wednesday, May 20, a day.

After Oil Marketing Companies (OMCs) implemented another round of fuel price hikes amid rising global crude oil prices linked to the ongoing Iran-US conflict.

The latest increase marked the second fuel price revision within a week. Earlier, OMCs had already raised petrol and diesel prices by Rs 3 per litre as mounting geopolitical tensions in West Asia continued to disrupt global energy markets and push crude prices higher.

India, which imports nearly 85-90 per cent of its crude oil requirements, remains highly vulnerable to fluctuations in international oil prices and supply disruptions caused by geopolitical instability.

The sustained rise in crude prices has also increased pressure on India’s foreign exchange reserves, while OMCs are reportedly facing significant daily losses due to elevated import costs.

Fuel retailers revise petrol and diesel prices every day at 6 AM based on global crude benchmarks and fluctuations in currency exchange rates.
