Petrol and Diesel Price Hike After Diwali? What a $110 Oil Shock Means for Your Money

India is paying far more for oil than it did a year ago, and most people at the petrol pump have not felt it yet. That gap is the story. Somebody is absorbing the difference, and the question heading into November is who keeps doing it, and for how long.

The numbers behind the headline

India's crude import basket averaged $120.46 a barrel in October through the 26th. That is the highest monthly average since March 2012. Brent itself has traded in the region of $110 to $115 in recent reports, with one closing print near $109.86.

Volumes are up too. Kpler data pointed to October imports of roughly 5.4 to 5.6 million barrels a day, which would be a record, as refiners diversified supply between Russia and West Asia. So India is buying more oil at a higher price. That combination is what pushes the import bill to a multi-year high.

Why diesel is the sharper edge

Crude is only half of it. Through the Middle East conflict and the disruption around the Strait of Hormuz, crude flows have largely recovered, but refined products have not. One analysis, citing Kpler, says refined product flows through Hormuz are only a little over half of pre-war levels, a shortfall of about 3 million barrels a day.

The result is that wholesale diesel prices topped $200 a barrel in September, nearly double crude. IEA members agreed to prioritise releases of diesel stocks, and the agency does not expect diesel inventories to be rebuilt before the second half of 2027. For a country where diesel moves freight, farm equipment and a large share of industry, that matters more than the crude number alone.

Who is paying today

Retail prices have not moved. State-run oil marketing companies have held pump prices steady and taken heavy under-recoveries, meaning they sell below what the product costs them. Domestic LPG prices have been unchanged since 7 June 2026, and commercial LPG, which tracks international benchmarks, is under review for revisions from 1 November.

The government is carrying part of the load as well. Subsidy spending in the first six months of the financial year reached Rs 2.2 lakh crore, which official data reports as being driven by higher petroleum product and fertiliser costs. Reports also say the windfall tax on diesel and aviation fuel exports was raised, though we could not independently confirm the exact rates, so treat that detail with care.

The fiscal squeeze

The Centre's fiscal deficit stood at about Rs 7.14 trillion for April to September, or 42.1% of the full-year target. A year earlier the same figure was 36.5%. Revenue expenditure grew 10% while revenue receipts rose just 3.6%, and the full-year target is 4.3% of GDP, about Rs 16.96 trillion.

Some analysts flag possible slippage of up to Rs 1.4 lakh crore if capital spending and tax collections do not pick up in the second half. This is the real limit on the "absorb it" strategy. Every rupee of subsidy is a rupee not available for capital expenditure or for keeping the deficit target intact. Holding pump prices is a choice, and it has a visible cost on the government's books.

What happens if prices are raised

Business Today has reported that petrol and diesel prices could come under pressure after Diwali, though no hike is confirmed. If one comes, the transmission is fairly direct. Diesel feeds into transport costs, which feed into food and goods prices. Economists estimate each $10 rise in crude adds roughly 40 to 50 basis points to the inflation trajectory, and food inflation was already elevated, with one report citing 7.74% in September.

A hike would, however, ease the pressure on oil companies' margins and reduce subsidy needs. So it trades one problem for another. Households and inflation take more of the strain; the deficit and company balance sheets take less.

The rupee and the external side

ICRA estimates that every $10 increase in crude widens the current account deficit by about 0.3% of GDP. Projections for FY27 put the deficit as high as 2.3% of GDP, against 0.9% in FY26, though estimates differ and other analyses see it nearer 1% because of strong services exports and remittances. Reports place the rupee close to record lows around 96 to 97 per dollar, with sources disagreeing on the exact level.

Foreign exchange reserves have been slipping as well, at about $719.8 billion in the week ended 23 October, down $1.3 billion on the week as lower gold valuations outweighed gains in foreign currency assets. Reserves are still large, but they are the cushion against exactly this kind of shock.

What this means for a retail investor

Nobody can say when oil turns, and this post is not a call on any stock or the market's direction. What you can do is map the mechanism onto your own holdings. Companies with large fuel or freight costs, such as airlines, paints, tyres and logistics, have margins that move with crude. Oil marketing companies sit on the other side, exposed to whether they can pass costs on. Rate-sensitive assets such as long-duration debt funds react to inflation and fiscal signals.

The practical step is a check of concentration: if several of your holdings share the same oil-price exposure, a single fuel-price decision hits them together. Look at your equity and debt fund factsheets for sector weights, and decide whether that overlap is deliberate.
