How Crude Oil Prices Affect India's Inflation and Current Account

India's Most Important Import

India imports most of the crude oil it uses. According to PPAC data, import dependence was 88.7% in FY26. That makes the global oil price one of the most important numbers for India's economy, and for many Indian companies.

When oil prices change, the effect does not stay in one place. It travels through four channels at once.

Channel 1: The Current Account

India pays for oil in dollars. A higher oil price means a bigger import bill and a wider current account deficit, the gap between what India earns from and pays to the rest of the world.

A common rule of thumb, used by bank economists in 2026, is that each $10 rise in the price of a barrel adds about $12 billion, or roughly 0.3% of GDP, to the current account deficit. In the April to June 2026 quarter, India's crude oil import bill reached a record $49.7 billion, up 61% from a year earlier, according to PPAC.

Channel 2: The Rupee

A bigger import bill means more demand for dollars. That puts pressure on the rupee. A weaker rupee then makes every barrel more expensive in rupee terms, which can deepen the effect.

Illustrative example.

The dollar price rose 37.5%, but the rupee price rose about 48%, because the currency weakened at the same time.

Channel 3: Inflation

Oil reaches prices directly and indirectly.

• Directly, through petrol, diesel, LPG and kerosene prices paid by households.
• Indirectly, through transport costs, fertilisers, plastics, paints, chemicals and many manufactured goods.

How much reaches consumers depends on fuel pricing. Retail petrol and diesel prices in India are often held steady for long periods, with oil marketing companies and the government absorbing part of the shock. That is why wholesale inflation usually reacts faster than retail inflation. In early 2026, wholesale inflation rose from about 2.3% in February to 8.3% in April, while retail inflation rose only from about 3.2% to 3.5%.

Over time, the effect spreads. By September 2026, retail (CPI) inflation had risen to 5.54%, measured on the new 2024 base, with food inflation at 7.74%.

Channel 4: The Government's Budget

When the government cuts fuel taxes to protect consumers, it gives up revenue. In 2026, it cut special excise duties on petrol and diesel by ₹10 per litre. When oil marketing companies sell fuel below cost, their losses may later need support. Subsidies on cooking gas and fertilisers also rise with oil prices. All of this can widen the fiscal deficit or force cuts elsewhere.

India's Above-Average Exposure

India's exposure is unusually high for three reasons. It imports almost nine-tenths of its crude oil. Its oil consumption is still growing as the economy grows. And its strategic petroleum reserves, stored in underground caverns at three coastal sites, hold only about 5.3 million tonnes, enough for around ten days of consumption. Countries with larger domestic production or bigger reserves can absorb shocks more easily.

Oil Shocks and RBI Policy

Central banks usually try to "look through" the first effect of an oil shock, because raising rates does not lower the price of oil. What worries them is the second round: when higher fuel and transport costs push up wages, rents and the prices of other goods, and people start to expect higher inflation in general.

In 2026, the RBI held rates through the first spike in oil prices in the spring. It raised them in October only after core inflation had risen, a large share of the CPI basket was showing price increases above 4%, and oil had climbed again. That sequence is typical: oil starts the problem, but the spread of inflation decides the policy response.

2026: The Channels in Action

The oil shock of 2026, linked to the crisis around the Strait of Hormuz, showed all four channels at work. India's crude basket averaged about $114 a barrel in April, eased to around $83 in June, and rose again to about $116 in September. The rupee weakened toward 95 per dollar. Retail inflation climbed, and in October the RBI raised its policy rate for the first time since 2023, citing oil prices among its reasons.

Winners and Losers Among Companies

• Hurt: oil marketing companies when retail prices are held, airlines, paint makers, tyre makers, chemical companies, and businesses with heavy transport costs.
• Helped or protected: upstream oil producers, some refiners when product margins widen, and exporters that gain from a weaker rupee.

Habits for Reading Oil Shocks

1. Track the Indian crude basket price published by PPAC, in dollars and in rupees.
2. Watch the current account and the rupee together.
3. Compare wholesale and retail inflation to see how much has been passed through.
4. Follow fuel tax decisions, which decide who bears the cost.
5. Map each company's oil exposure: input cost, fuel cost or product price.

The Reframe

For India, the oil price is not just a commodity price. It is a tax on the whole economy that the government, companies and households keep negotiating over who pays.
