Why Do Petrol and Diesel Prices Remain Relatively Stable?
Petrol and diesel rates have remained comparatively stable for a prolonged period following tax-related measures taken by the central government and several state governments after May 2022.
Although crude oil prices in the international market continue to fluctuate, domestic fuel prices have not always moved in line with every global change. Taxes, refining expenses and other factors also influence the final price consumers pay at petrol pumps.
What Factors Determine Petrol and Diesel Prices?
Several factors come together to determine the retail price of fuel in India. The major ones include:
1. International Crude Oil Prices
Crude oil is the primary raw material used to produce petrol and diesel. Therefore, a significant increase or decrease in international crude prices can influence fuel costs in India.
2. Rupee-Dollar Exchange Rate
India imports a large share of its crude oil requirements, with international purchases generally settled in US dollars. When the Indian rupee weakens against the dollar, the cost of importing crude can increase, potentially putting upward pressure on fuel prices.
3. Central and State Taxes
Taxes and duties imposed by the central and state governments make up a significant portion of the retail price of petrol and diesel. Since state-level taxes can differ, fuel prices are not identical across the country.
4. Refining and Distribution Costs
Crude oil must first be processed at refineries before it can be converted into usable fuels. Refining expenses can vary depending on crude oil quality, refinery efficiency and other operational factors. Transportation and distribution costs also contribute to the final retail price.
5. Demand and Supply
Market demand is another factor that can influence fuel prices. Consumption can rise during holiday periods, peak travel seasons and certain weather conditions, affecting the overall demand-supply balance.
