Petrol, diesel prices steady in major cities on September 29
Petrol and diesel prices remained largely unchanged across major Indian cities, with petrol at Rs 102.12 a litre and diesel at Rs 95.20 in New Delhi. In Mumbai, petrol was priced at Rs 111.21 and diesel at Rs 97.83. Indian Oil Corporation says rates are revised daily at 6 am under the dynamic pricing mechanism introduced in June 2017. Prices differ between cities due to state taxes such as VAT, transport costs and dealer commissions. Fuel remains outside GST.

Analysts’ view opinion
The real economic signal here is the non-event: prices did not move. Even with a daily revision mechanism in place, retail rates staying flat suggests that swings in crude and the rupee are being absorbed somewhere upstream rather than passed to the pump. Petrol at Rs 102.12 in Delhi versus Rs 111.21 in Mumbai — that roughly Rs 9 gap is a story about state taxation, not global markets.
- Flat pump prices are mildly disinflationary at the margin, and because diesel feeds freight and farm costs, a steady diesel rate helps contain second-round price pressure across goods.
- With global oil described as elevated and volatile in September while retail prices stay unchanged, the volatility is likely showing up in oil marketing companies' margins rather than in consumer bills.
- The city-to-city spread is driven by VAT, transport costs and dealer commissions, meaning what a consumer pays is largely a function of state fiscal choices.
- Keeping petrol and diesel outside GST gives states a dependable revenue stream, but denies businesses input tax credit and raises their costs — the honest case on both sides of that long-running debate.
- With petrol above Rs 100 and diesel above Rs 95 in major markets, fuel remains a heavy fixed line in household budgets, keeping pressure on discretionary spending.
What to watch — Watch crude prices, the rupee-dollar rate and any state-level tax changes — a move in any one of them will decide how long this stability lasts.
The story does not establish why prices held steady, what is happening to refiner or retailer margins, or whether any tax or GST change is under consideration — those remain inferences, not reported facts.

Research brief · 8 facts · 3 dates · exam-readyThe brief
Context
Petrol and diesel in India are sold at prices revised by oil marketing companies every morning under a "dynamic fuel-pricing" system in place since June 2017, replacing fortnightly revisions. On September 29, 2026, pump prices held largely steady in major cities, with petrol above Rs 100 a litre in most metros. Because petrol and diesel remain outside the GST regime, state-level VAT, freight and dealer commissions produce wide city-to-city differences — Delhi's petrol rate is roughly Rs 9 a litre cheaper than Mumbai's.
Key facts
- New Delhi on September 29, 2026: petrol Rs 102.12 per litre, diesel Rs 95.20 per litre.
- Mumbai on September 29, 2026: petrol Rs 111.21 per litre, diesel Rs 97.83 per litre.
- Prices were largely unchanged across major Indian cities; petrol stays above Rs 100/litre in most metros and diesel above Rs 95/litre in several markets.
- Fuel rates are revised daily at 6 am under the dynamic fuel-pricing mechanism introduced in June 2017, per Indian Oil Corporation (IOC).
- Petrol and diesel are currently outside the GST regime, so state VAT remains a major determinant of retail price.
- City-to-city price gaps arise from state-level taxes (especially VAT), transportation costs and dealer commissions.
- Consumers can get an indicative local rate by SMSing 'RSP <space> Dealer Code' to 92249 92249 (Indian Oil service).
- IOC says prices can differ slightly between individual outlets within the same city or sales area.
Timeline
- June 2017India introduces the dynamic fuel-pricing mechanism, with daily revision of petrol and diesel rates at 6 am.
- September 24 and 25, 2026Earlier daily fuel-rate updates published for Delhi, Mumbai, Kolkata and Chennai.
- September 29, 2026, 07:48 ISTLatest rates reported: Delhi petrol Rs 102.12/diesel Rs 95.20; Mumbai petrol Rs 111.21/diesel Rs 97.83.
Who has a stake
- Consumers and commuters — Pump prices above Rs 100 a litre for petrol in most metros directly affect household transport and fuel budgets.
- Indian Oil Corporation and other oil marketing companies — Set and communicate daily 6 am revisions; absorb or pass through crude and exchange-rate movements.
- State governments — VAT on petrol and diesel is a significant revenue source; fuel's exclusion from GST preserves their taxation power.
- Fuel dealers and retail outlets — Dealer commissions form part of the retail price; rates can vary slightly between outlets in the same sales area.
- Transport and logistics operators — Diesel above Rs 95 a litre in several markets feeds into freight costs and broader price pressures.
Why it matters
Fuel prices are among the most visible, politically sensitive prices in India and feed into transport and freight costs. Because petrol and diesel sit outside GST, identical products cost materially different amounts across cities, keeping the question of fuel taxation and tax harmonisation alive. With India importing a large share of its crude, elevated global oil prices and rupee movements remain a standing risk to household budgets.
UPSC angle
Prelims pointers
- Dynamic (daily) fuel pricing in India was introduced in June 2017; rates change at 6 am each day.
- Petrol and diesel are outside the GST regime; state VAT applies to them.
- Delhi petrol on September 29, 2026: Rs 102.12/litre; diesel Rs 95.20/litre.
- Mumbai petrol on September 29, 2026: Rs 111.21/litre; diesel Rs 97.83/litre.
- Indian Oil's SMS facility: send 'RSP <space> Dealer Code' to 92249 92249 for indicative local price.
- Key determinants of retail fuel price: global crude prices, rupee-dollar rate, state VAT, transport cost, dealer commission.
Mains framing
Retail fuel pricing in India illustrates the interaction of global markets, exchange rates and domestic federal taxation. Since June 2017, oil marketing companies have revised petrol and diesel rates daily at 6 am, transmitting movements in international crude prices and the rupee-dollar rate to consumers, given that India imports a large share of its crude requirement. Yet the final pump price is shaped as much by domestic factors: state-level VAT, transportation costs and dealer commissions, which is why petrol costs Rs 102.12 a litre in New Delhi but Rs 111.21 in Mumbai on the same day, with variation even between outlets in one sales area. Because petrol and diesel remain outside GST, states retain substantial taxation autonomy — a revenue cushion for them, but a source of price divergence and cascading cost for consumers and transporters facing diesel above Rs 95 a litre. The implications run from household inflation to freight costs. A balanced way forward, consistent with the facts available, involves greater transparency in the price build-up, closer tracking of crude and currency risk, and a considered Centre-State conversation on how fuel is taxed, weighing consumer relief against state revenue needs.
Key terms
- Dynamic fuel pricing
- System introduced in June 2017 under which petrol and diesel retail prices are revised every day at 6 am instead of periodically.
- VAT (Value Added Tax)
- State-level tax levied on petrol and diesel, the main reason retail fuel rates differ across states and cities.
- GST regime
- India's unified indirect tax system; petrol and diesel are currently kept outside it, leaving state taxation in play.
- Indian Oil Corporation (IOC)
- State-run oil marketing company that effects daily 6 am price changes and offers an SMS-based indicative price service.
- Dealer commission
- Margin paid to retail fuel outlets, one of the components built into the final pump price.
- Rupee-dollar exchange rate
- Currency factor that alters the landed cost of imported crude and hence domestic petroleum product prices.
Practice questions
- Petrol and diesel remain outside the GST framework. Examine the implications of this exclusion for consumers, state finances and price uniformity across India.
- How do global crude oil prices and the rupee-dollar exchange rate transmit to retail fuel prices in India under the dynamic pricing mechanism introduced in 2017?
- Account for the roughly Rs 9 per litre difference in petrol prices between New Delhi and Mumbai, and discuss what it reveals about India's fiscal federalism.
