Why Crude Oil Prices Rise or Fall (and How It Affects India)
Crude oil prices rise or fall with the balance between global supply and demand. Supply depends on OPEC+ output, US shale production and shipping routes. Demand depends on economic growth, especially in the US, China and India. Wars and supply shocks move prices fastest, because they threaten supply overnight. India imports close to 90% of the crude it uses, so these swings affect petrol, diesel and LPG prices, inflation and the rupee.
Benchmarks: Brent and WTI
- Brent (North Sea): the global benchmark, and the one most relevant to India’s imports.
- WTI (West Texas Intermediate): the US benchmark.
- India also tracks the Indian basket, a mix of the grades Indian refiners buy, published by PPAC (Petroleum Planning & Analysis Cell).
What pushes oil prices up
- OPEC+ production cuts: Saudi Arabia, Russia and other producers agree to pump less.
- Wars and supply disruptions: conflict in a producing region or on a shipping route cuts supply, or threatens to. Traders add a “risk premium” even before any barrel is lost.
- Strong demand: fast economic growth, the summer driving season in the US, and winter heating.
- Low inventories: when stockpiles are thin, any shock has a bigger price effect.
- A weaker US dollar: oil is priced in dollars, so a weaker dollar makes it cheaper for other buyers and tends to lift demand.
What pushes oil prices down
- OPEC+ raising output, or members producing above their quotas.
- Higher US shale production.
- Economic slowdowns or recessions that cut fuel demand.
- Rising inventories and the release of strategic reserves.
- Easing of a conflict, or reopening of a disrupted route.
Why oil prices rise during wars: the 2026 example
In early 2026, conflict in the Middle East disrupted traffic through the Strait of Hormuz, the route for about a fifth of the world’s oil. The US Energy Information Administration (EIA) reported that Gulf producers had shut in about 7.5 million barrels a day by March 2026, and Brent averaged about $103 a barrel that month. After the strait reopened, the EIA’s September 2026 outlook expected Brent to average around $90 in the second half of 2026 and $74 in 2027, as production and inventories recover.
The pattern is typical: a sharp spike on the supply shock, a risk premium while uncertainty lasts, then a gradual fall as supply returns and high prices cut demand.
How crude prices affect India
- Import bill and the rupee: India’s crude import dependence reached a record 88.7% in 2025-26 (provisional, per the Petroleum Ministry). Higher oil prices mean more dollars spent on imports, which puts pressure on the rupee.
- Inflation: fuel feeds into transport and manufacturing costs, and so into food and goods prices.
- Government finances: subsidies on LPG and excise duty decisions come under pressure.
- Stock market: oil marketing companies, paint, tyre, aviation and chemical companies are hurt by higher crude. Upstream producers such as ONGC and Oil India tend to benefit.
Why petrol prices don’t move daily with crude
Petrol (since 2010) and diesel (since 2014) prices are market-linked on paper, and are set by oil marketing companies (IndianOil, BPCL, HPCL). In practice, retail prices are often held steady for long periods, with the companies absorbing losses when crude is high and recovering them when it falls. A large part of the pump price is tax: central excise duty plus state VAT, which is why petrol costs different amounts in different states. The government can also cut or raise excise duty to cushion a spike.
LPG and oil shocks
India imports more than half of the LPG it uses, mostly from Gulf countries. A disruption around Hormuz therefore hits cooking gas supply as well as crude. Domestic LPG cylinder prices are revised by the oil companies, usually at the start of the month. Subsidy, where applicable, is paid to the bank account: see LPG subsidy status check.
Frequently asked questions
How much does a $10 rise in crude affect India?
It raises the import bill by billions of dollars a year and adds to inflation and pressure on the rupee. The exact effect depends on the exchange rate and how much of the rise is passed on at the pump.
Where can I see official Indian fuel prices?
PPAC (ppac.gov.in) publishes the Indian basket crude price and retail selling prices. Oil companies’ websites and apps show the current price in your city.
