Petrol and diesel price changes
Oil prices change daily based on global markets, crude oil rates, taxes, and transportation costs. That’s why fuel prices vary across states and cities even on the same day. If you commute daily or are planning a long drive this weekend, today’s petrol and diesel prices can directly affect your budget.
Prices have remained stable for the past two years
Since May 2022, petrol and diesel prices have remained stable following tax cuts by the central government and several states. Although the international market fluctuates, prices for Indian consumers have remained relatively stable.
Factors that determine fuel prices
Crude Oil Prices: Petrol and diesel are primarily produced from crude oil. When international crude oil prices rise, it directly impacts the Indian market.
Rupee Against the Dollar: India imports most of its crude oil, and it is purchased in dollars. If the rupee weakens, fuel becomes more expensive.
Government Taxes and Duties: The central and state governments impose heavy taxes on petrol and diesel, which constitute a significant portion of the retail price. This is the reason for the price differences across states.
Refining Costs: The process of making crude oil usable (refining) also incurs costs. This cost depends on the quality of the crude oil and the refinery’s capacity.
Demand and Supply Balance: If fuel demand increases in the market, prices also tend to rise. Fuel consumption is especially high during festivals, summer, or winter.
