The Global Oil Picture Shifts
Recent developments in the global energy market appear, on the surface, to be good news for consumers. In a series of meetings, the OPEC+ consortium, which includes major producers like Saudi Arabia and Russia, has agreed to unwind previous voluntary
production cuts. For September 2026, this means an increase of about 188,000 barrels per day, completing a rollback that began earlier. In theory, more supply should ease pressure on crude oil prices. After a volatile period, Brent crude, the international benchmark, has been trading at around $81 per barrel. While this is higher than a year ago, it's a significant drop from recent peaks, with some analysts forecasting a market surplus and potentially lower prices ahead.
From Crude Barrel to Retail Nozzle
The price of crude oil is only the beginning of the story for India, which imports over 85% of its oil requirements. First, Indian Oil Marketing Companies (OMCs) like Indian Oil and BPCL buy crude oil at global prices. This cost, converted from dollars to rupees, forms the 'base price' of petrol and diesel. After refining, this base price is what the fuel technically costs before it leaves the refinery gate. But this is nowhere near the price you pay. As of early August 2026, the petrol price in Delhi was around ₹102.12 per litre, while in Mumbai it was significantly higher at ₹111.21. So, what happens between the refinery and the fuel pump to cause this dramatic increase?
The Decisive Role of Domestic Taxes
The largest components added to the base price of fuel in India are taxes, levied by both the Central and State governments. The Central government imposes a fixed excise duty, while State governments levy a Value Added Tax (VAT), which is a percentage of the price. Combined, these taxes can account for nearly half, and sometimes more, of the final retail price. For instance, even when global crude prices fall, if governments don't reduce these taxes, the benefit is not passed on to consumers. Instead, the higher taxes are maintained, or in some cases, the government might even absorb the difference to bolster its revenues or prevent price shocks.
The Government's Revenue Imperative
This isn't arbitrary. For both Central and State governments, taxes on petrol and diesel are a massive, reliable, and easy-to-collect source of revenue. These funds are critical for financing everything from large-scale infrastructure projects like highways and bridges to social welfare schemes and managing the country's overall fiscal health. When faced with a choice between lowering fuel prices and securing funds for public spending, governments often prioritize revenue. The political calculation is a difficult one: cutting fuel taxes brings immediate public relief and can help control inflation, but it creates a significant hole in the budget that must be filled from elsewhere.
A Policy Tightrope Walk
This dynamic turns fuel pricing into a constant balancing act. Higher fuel prices have a cascading effect on the economy, increasing transportation costs, which in turn makes food and other essential goods more expensive, stoking inflation. However, the revenue from fuel taxes is equally essential for driving economic growth and funding development. The Indian government sometimes uses mechanisms like windfall taxes on fuel exports or adjusts excise duties to navigate this challenge, aiming to protect consumers from extreme price volatility while ensuring state coffers don't run dry. This is why fuel prices often remain stubbornly high or change little, even when global market conditions seem favourable.
