If your neighbourhood fuel station has been running low on diesel lately, a Rs 40 to Rs 42 per litre price gap may be the reason.

Bulk buyers, including state road transport corporations, telecom tower operators and industrial genset users, are supposed to purchase diesel from dedicated bulk supply channels at market-linked prices.
But retail pump prices are being held much lower than bulk rates. That difference has created a strong incentive for large consumers to route their purchases through ordinary petrol pumps instead.
The result is visible at the pump level. Demand at some retail fuel stations has surged 20 to 30 percent, and a few locations have seen dry-out-like situations. The government has said overall fuel supply remains adequate, but the pressure is showing at the distribution end.
At the heart of this issue is a pricing anomaly. Retail diesel at ordinary petrol pumps is significantly cheaper than bulk diesel. In Delhi, retail diesel is around Rs 91.58 per litre, while bulk diesel is about Rs 40 to Rs 42 per litre higher.

For a small car owner, that gap is only an interesting number. For a bulk consumer, it is a major saving. A 5,000-litre purchase at a Rs 40 per litre gap means a saving of Rs 2 lakh.
A transport operator, telecom tower company or industrial user buying diesel regularly has a strong financial reason to avoid the bulk channel if enforcement is weak.
That is why the shift is happening. It is not because the country has suddenly run out of diesel. It is because the cheaper retail channel is being used by consumers for whom it was not meant.
Retail pumps are designed to serve ordinary vehicle users, small commercial vehicles and local demand. They are not meant to replace bulk supply points for large diesel users.

When bulk buyers begin filling through retail pumps, the demand spike can be sharp and localised. This is why some regions are seeing fuel stations run low even though oil companies say national supply is adequate.
The agricultural season is adding to this pressure. Diesel demand usually rises when farm activity increases because tractors, pump-sets and transport vehicles all consume more fuel. When seasonal rural demand and bulk-buyer diversion hit the same retail network, certain pumps face a sudden load they were not stocked for.
Data from the first half of May shows the wider pressure. Diesel sales by state-run fuel retailers rose nearly 11.5 percent year-on-year to about 3.8 million metric tonnes. Petrol sales rose even faster, up 19 percent to around 1.8 million tonnes.

The pressure is not evenly spread across all fuel stations. State-run fuel retailers are seeing higher footfall because their pump prices are generally lower than private-sector fuel stations. This is because true deregulation has not happened.
That creates a second layer of imbalance. Private fuel retailers face market-linked economics more directly, while state-run companies are expected to maintain stable retail prices. When buyers chase the lower price, they put more load on the public-sector retail network.
For ordinary buyers, the experience can look like a shortage. They see long queues, delayed deliveries and pumps temporarily running dry. But the government’s position is that this is not a supply crisis. It is a distribution and pricing problem. This is a self-created problem due to bad policy making!
Keeping retail diesel prices below market level while bulk consumers pay market-linked rates creates an arbitrage opportunity. The wider the gap, the stronger the incentive to misuse the retail channel.
Enforcement at the pump level is difficult. A diesel-consuming commercial vehicle at a retail pump does not always look suspicious. Pump operators also earn from volume, so they may not have a strong reason to refuse business unless clear instructions and monitoring systems are in place.
The government has said efforts are being made to monitor sales and ensure adequate supply at petrol pumps. Local authorities and police may also be involved in curbing inappropriate bulk purchases through retail outlets.
For now, the problem is likely to continue as long as the price gap remains large. Regular buyers should understand that a dry pump does not always mean a national fuel shortage. It may simply mean bulk consumers are buying from the same pump network meant for everyday vehicle users.
