Oil above $100: how the Gulf shock is reaching India’s interest rates, trade and businesses

Brent has stayed above $100 for most of eight months. We trace how the Iran war shock has already pushed up India's interest rates and trade deficit, who is most exposed, and three scenarios to watch.

Crude oil has now spent most of the past eight months above $100 a barrel, and on 16 October 2026 Brent traded between roughly $105 and $109 depending on the hour. For India, which buys most of its oil abroad, this is no longer a short-lived spike. It has started to change interest rates, the trade balance and the costs facing ordinary businesses. This analysis sets out why prices are high, how the shock is travelling through the Indian economy, and which conditions would make it worse or better.

Why oil is still above $100

The main driver is the war involving Iran. Al Jazeera reported on 15 October that disruption to shipping through the Strait of Hormuz has pushed energy prices up worldwide, and that crude has been above $100 for much of the past eight months. G20 finance ministers meeting in Bangkok that week were discussing the inflation fallout alongside the IMF and World Bank annual meetings.

Fresh tension is still being added. According to HDFC Sky’s 16 October market report, attacks on vessels over the previous ten days had raised concerns about shipping routes, and Iran said it was stepping up strikes in response to a US blockade of its ports. The same report noted that US crude inventories fell by 8.6 million barrels in the week to 9 October, far more than the 288,000-barrel fall analysts had expected, a sign that supply is tight even outside the Gulf.

What is holding prices back

Governments are trying to add supply. The International Energy Agency launched a 400-million-barrel emergency stock release in March. Al-Monitor reported that on 7 October IEA members agreed to speed up the roughly 100 million barrels from that plan that had not yet reached the market, prioritising diesel, which has hit record prices in many countries. Analysts quoted in that report cautioned that this mostly accelerates oil already promised rather than adding new volume. IEA governments still hold about 1.1 billion barrels of public emergency stocks.

Washington is also reported to be considering lifting sanctions on some “shadow fleet” tankers to ease record freight rates. HDFC Sky noted that the scope of that proposal, and how much real supply it would add, is unclear. These measures can soften prices at the margin, but none of them replaces the oil that cannot move freely through Hormuz.

How the shock reaches India

1. Interest rates

The clearest effect so far is on monetary policy. On 7 October the Reserve Bank of India raised its repo rate by 25 basis points to 5.50% and changed its stance from neutral to “calibrated tightening”. The RBI’s statement links the move partly to oil: it records the Indian crude basket averaging $82.0 a barrel in July, $90.2 in August and $116.1 in September, cites the re-escalation of the West Asia conflict in September, and names volatile oil prices among the pressures on inflation. The RBI signalled that its next move would be a hike or a pause rather than a cut, and SCC Times reported that the rate decision itself was unanimous.

The RBI now projects consumer inflation of 5.2% for 2026-27, rising to 6.0% in the October–December quarter. It also raised its growth forecast to 7.1%, so the central bank is not predicting a slump. It is signalling that it will accept tighter credit to stop imported energy costs from becoming persistent inflation.

2. The trade deficit and the rupee

Oil is India’s largest import, so higher prices widen the gap between what the country buys and sells. India’s merchandise trade deficit rose to $30.21 billion in September from $26.86 billion in August, according to figures cited by Equentis. The same article reports an ICICI Bank Global Markets projection that the annual goods deficit could reach about $388 billion, with a current account deficit near $57 billion, or 1.4% of GDP. That projection assumed oil averaging about $95, below where Brent trades today. A wider deficit means more demand for dollars, which puts pressure on the rupee and in turn makes imported oil more expensive in rupee terms.

3. Business costs

Fuel is an input for almost every business: trucking, airlines, shipping, fertilisers, plastics, paints and chemicals all use oil or its derivatives. When those costs rise faster than companies can raise prices, margins shrink. Diesel matters most for India because it moves most goods by road, which is why the IEA’s focus on diesel releases is significant for Indian logistics costs.

Who is more exposed, and who is less

As a general pattern, not a forecast for any single company:

  • More exposed: businesses whose main cost is fuel or oil-based raw materials and who cannot pass costs on quickly. Airlines, road logistics, paint and tyre makers, and chemicals producers usually fall in this group.
  • Mixed: fuel retailers and refiners. Refining margins can rise when diesel is scarce, but retailers can lose money if pump prices are held below cost.
  • Less exposed or benefiting: domestic oil and gas producers, whose output sells at higher prices, and exporters whose earnings are in dollars while the rupee is under pressure.
  • Borrowers: anyone with floating-rate loans faces higher interest costs after the RBI’s hike, whatever their fuel use.

Three scenarios to watch

These are conditional scenarios, not predictions. Each depends on assumptions that could change quickly.

Scenario What would have to happen Likely direction for India
Easing Shipping through Hormuz normalises, or emergency releases and sanctions relief add meaningful supply Lower import bill, less pressure on the rupee, room for the RBI to pause
Stalemate Brent stays roughly $100–110 with intermittent attacks on shipping Inflation near RBI’s 6% Q3 projection; tight credit persists
Escalation Further damage to Gulf infrastructure or wider shipping closures Higher fuel inflation, wider deficit, risk of further rate rises

What to watch next

  • Monthly Indian crude basket prices from the Petroleum Planning & Analysis Cell, which the RBI itself uses.
  • India’s October trade data, for the size of the oil import bill.
  • Whether the IEA’s accelerated releases actually lower diesel prices.
  • Any change in shipping conditions in the Strait of Hormuz and the Red Sea.
  • The RBI’s next policy decision, after its shift to a tightening stance.

Bottom line

For India, $100-plus oil has moved from a market headline to an economy-wide cost. It has already contributed to a rate rise and a wider trade deficit. How long it lasts depends mostly on events in the Gulf rather than on anything Indian policymakers control. The tools they do control are interest rates, fuel taxes and stock releases, and those can soften the blow but not remove it.
