Under-recovery: the book that never reconciles.

India's three downstream OMCs (IOC, BPCL, HPCL) are technically free-market retailers since 2010 for petrol and 2014 for diesel. In practice they hold retail flat through crude shocks for weeks or months, absorbing losses and recovering later when crude softens. The fiction and the reality, in four layers.

01 / 04The fiction

Free-market pricing, daily dynamic

Petrol 2010 · Diesel 2014

On paper, OMCs revise dealer transfer prices daily based on a formula tracking the 15-day average of Indian Crude Basket + exchange rate + refinery gross refining margin. The formula is public; the official price publication carries the notified dealer transfer price daily.

The system was designed to remove the deficit-generating subsidy mechanism of the 2000s where the Union paid OMCs explicit "oil bonds" to compensate for below-cost selling.

See the company quarterly disclosures for marketing-segment margin volatility (IOC, BPCL, HPCL quarterly presentations break out refining vs marketing). The official dealer-transfer price data is tracked in data/daily_rsp.jsonl.
