Oil marketing companies (OMCs) in India are facing significant losses as bulk diesel buyers switch to retail pumps, where prices are approximately ₹50 cheaper per litre. The decline in bulk sales, estimated at 30-50%, is attributed to rising global oil prices following the Iran conflict. For instance, in Delhi, bulk diesel is priced at ₹134.5 per litre, while retail is at ₹87.6, creating a substantial price gap. This shift is impacting OMCs as they continue to incur losses on retail sales, having not raised retail prices despite the increased costs of diesel for bulk customers. Bulk sales, which represent about 12% of India's diesel consumption, have historically offered discounts over retail prices, but these discounts have largely disappeared. The trend mirrors a similar shift during the Ukraine war in 2022, when bulk customers opted for retail due to cheaper prices. OMCs are currently more inclined to lose market share rather than offer discounts amidst elevated global diesel prices.
