Petrol and Diesel Prices Today, September 12, 2026: Check City-Wise Fuel Rates and What Rising Crude Means for India
Petrol and diesel prices across major Indian cities remained unchanged on September 12, 2026, even as international crude oil markets continued to face significant pressure from geopolitical tensions and concerns over global supply.
For motorists, the immediate picture is one of stability at fuel stations. However, the international oil market is sending a different signal. Crude prices recently climbed to multi-month highs before easing in the latest trading session, while uncertainty surrounding shipping through the Strait of Hormuz continues to keep energy markets on edge.
The stability in domestic fuel rates is therefore significant. India imports a substantial amount of its crude oil, making international oil prices an important factor for the country's economy, transportation costs and household budgets.
Here is a detailed look at petrol and diesel prices on September 12, the factors influencing them and what consumers should watch in the coming days.
Petrol and Diesel Prices on September 12
There was no fresh revision in petrol or diesel prices across the major cities covered in the latest update. According to the reported rates, petrol continues to be priced at ₹102.12 per litre in Delhi, while Mumbai's petrol price stands at ₹111.21 per litre. Chennai and Kolkata have rates of ₹107.77 and ₹113.51 per litre, respectively.
The city-wise rates reported for September 12 are:
| City | Petrol Price | Diesel Price |
|---|---|---|
| Delhi | ₹102.12/litre | ₹95.20/litre |
| Mumbai | ₹111.21/litre | ₹97.83/litre |
| Kolkata | ₹113.51/litre | ₹99.82/litre |
| Chennai | ₹107.77/litre | ₹99.55/litre |
| Hyderabad | ₹115.69/litre | ₹103.82/litre |
| Bengaluru | ₹110.89/litre | ₹98.80/litre |
These rates show how significantly fuel prices can differ between Indian cities. Local taxes and other components of the retail price structure contribute to these differences.
Why Have Petrol and Diesel Prices Remained Unchanged?
One of the most important developments is that domestic fuel prices have not immediately followed the recent rise in global crude prices.
The reported rates have remained unchanged since May 25, when petrol and diesel prices were increased by ₹7.50 per litre. Since then, domestic retail prices have stayed stable despite considerable movement in the international oil market.
This does not necessarily mean that changes in global crude prices have no impact on India. Instead, the relationship between international oil prices and retail fuel rates involves several factors.
Global crude oil prices
Crude oil is the fundamental raw material used to produce petrol and diesel. When international crude becomes more expensive, the cost pressure on companies involved in fuel supply generally increases.
The latest market movement illustrates this clearly. Brent crude had climbed as high as $107.63 a barrel on September 11, while WTI reached $102.48 amid concerns about supply disruptions. In the latest session, Brent settled at $104.61 and WTI at $100.05.
The rupee-dollar exchange rate
India purchases crude oil in the international market, where transactions are primarily denominated in US dollars. Consequently, currency movements can influence the effective cost of imported crude.
A weaker rupee can make imported oil more expensive in domestic currency terms, while a stronger rupee can provide some relief.
Taxes and other costs
The price consumers see at a petrol station is not simply the international price of crude converted into rupees.
Domestic fuel prices also reflect factors such as refining costs, dealer commissions, taxes and other components of the pricing structure. This is why changes in global crude prices do not necessarily translate into an identical or immediate movement in retail fuel prices.
Why Global Oil Prices Are Rising
The latest increase in crude prices has been closely connected with geopolitical developments and concerns over energy supplies.
The Strait of Hormuz is particularly important because it is a major maritime route for global energy shipments. Any prolonged disruption or deterioration in shipping conditions can raise concerns among traders about whether sufficient crude will reach international markets.
The latest report points to worsening maritime conditions around the Strait of Hormuz and continuing US-Iran tensions as important factors behind the recent volatility in crude prices.
Even when actual supply losses are limited, the possibility of disruption can influence oil prices because traders begin pricing in the risk of tighter future availability.
What Does This Mean for Indian Consumers?
For motorists, unchanged petrol and diesel prices offer short-term relief.
A commuter who drives to work every day, a family planning a road trip or a small business dependent on vehicles can continue budgeting based on current fuel rates without facing an immediate increase.
However, stable prices should not be interpreted as a guarantee that rates will remain unchanged indefinitely.
If international crude prices remain elevated for a prolonged period, pressure can increase on domestic fuel suppliers. The eventual impact on consumers would depend on several factors, including global crude prices, currency movements, domestic taxes and the pricing decisions of oil marketing companies.
Impact on transport costs
Diesel is especially important for India's logistics and transportation network. Trucks, buses, agricultural machinery and several commercial vehicles rely heavily on diesel.
Therefore, a sustained increase in diesel prices can potentially raise transportation expenses. Over time, higher logistics costs can influence the prices of goods transported across the country.
This is one reason fuel prices matter beyond the petrol pump.
India's Fuel Demand Also Shows an Important Trend
Another notable development is the reported decline in India's fuel consumption.
According to figures cited in the report, India's fuel demand fell 6.3% in August to 18.61 million metric tons, marking a near two-year low. This decline occurred as crude prices were coming under pressure and international oil prices moved above the $100-a-barrel level.
Lower fuel demand can have several possible explanations. Consumers may reduce unnecessary driving when fuel becomes expensive, businesses may optimise transportation, and changing economic activity can also affect fuel consumption.
For policymakers and energy companies, demand trends are important because they provide clues about consumption patterns and the broader health of the economy.
Petrol Prices Differ Widely Across Major Cities
The September 12 rates also demonstrate the difference between fuel prices in India's major urban centres.
Delhi has the lowest petrol price among the six cities listed, at ₹102.12 per litre. Hyderabad has the highest at ₹115.69 per litre. The difference between these two rates is more than ₹13 per litre.
Mumbai's petrol price is ₹111.21 per litre, while Kolkata is at ₹113.51. Chennai is comparatively lower at ₹107.77, and Bengaluru stands at ₹110.89.
The differences highlight the role played by state-level taxation and local pricing structures.
What Should Consumers Watch Next?
The most important factor to watch is the direction of international crude oil prices.
If crude prices continue to remain elevated, pressure on India's fuel market could increase. On the other hand, a sustained decline in crude prices could reduce some of that pressure.
Consumers should also watch the rupee-dollar exchange rate because currency movements can influence the domestic cost of imported oil.
Geopolitical developments will remain another major factor. Any improvement in shipping conditions around major energy routes could reduce some supply concerns, while further disruptions could increase market volatility.
For households, the practical approach is to focus on actual retail prices rather than reacting to every daily movement in international crude.
How Fuel Prices Affect the Wider Economy
Petrol and diesel are closely connected to economic activity.
Petrol primarily affects individual motorists and private vehicle users, while diesel has a broader role in commercial transportation, logistics and several productive activities.
When fuel prices rise substantially, the effects can spread through the economy. Transportation companies may face higher operating expenses, which can eventually affect freight charges and the cost of moving goods.
Conversely, stable fuel prices can provide greater predictability for households and businesses.
That makes the current period of unchanged domestic prices important, particularly when global oil markets are experiencing heightened volatility.
