Will Rising Oil Prices Crash Indian Markets?

Whenever tensions rise between the United States and Iran, oil becomes the first thing everyone tracks. For India, that instinct is natural. The country imports nearly 85% of its oil. At current volumes, every sustained $10 increase in Brent crude adds roughly $17 billion to the annual import bill.

But expensive oil alone does not automatically destabilise markets. India has managed high oil prices before. The real question is not how high crude goes; it is how long uncertainty lasts.

Indian equities trade at a premium compared to many emerging markets. The Nifty is valued at around 22 times forward earnings. That multiple reflects confidence: stable inflation, a manageable rupee, and policymakers who retain room to respond when shocks appear. In simple terms, markets are pricing stability.

A brief oil spike does not break that assumption. Companies adjust margins. Policymakers fix taxes. Investors update earnings forecasts. The system absorbs the shock.

The problem begins when oil refuses to settle.

How Oil Quietly Pressures the Market

Higher oil prices mean higher dollar demand, which often pressures the rupee. A 4-5% depreciation, combined with a $20 rise in crude, raises the local cost of imports and gradually feeds into inflation. Research suggests that every sustained $10 increase in oil can add around 0.2-0.3 percentage points to headline inflation. We’ve previously broken down how a $10 rise in crude filters into everyday expenses, from fuel to groceries, in a separate analysis on its impact on monthly household budgets.

Markets, however, react before inflation shows up in official data. If investors expect price pressures to persist, bond yields begin to rise. A 50-75 basis point move in long-term yields may appear modest, but in a market trading near 22 times earnings, it can bring down market multiples, even if profits remain intact.

That is the real shift. Oil does not need to damage earnings immediately. It only needs to lift the cost of capital.

When High Oil Prices Last Longer

The impact of a US-Iran escalation depends less on the peak oil price and more on whether elevated levels persist.

Brent Crude Level	Short Duration	If It Persists
$95-100	Market volatility	Limited structural impact
$115-120	Currency swings, yield movement	Inflation concerns rise, valuations soften
$140+	Immediate risk-off sentiment	Policy flexibility narrows, premium under pressure

If crude spikes to $115 and quickly retreats, markets usually stabilise. The concern is when prices remain above $110-120 for several months. A sustained $20 increase would widen India’s import bill significantly and push the current account deficit higher, even if not to crisis levels. That keeps steady pressure on the rupee and reduces policy comfort.

Over time, that pressure can lift bond yields. And once yields move higher for long enough, the premium valuations investors are currently willing to pay begin to face scrutiny.

What Past Oil Crises Show?

History shows that duration changes outcomes. Between 2011 and 2013, Brent crude averaged above $100 for an extended period. Inflation stayed elevated, external balances weakened, and the rupee depreciated sharply. The stress built gradually because the pressure lasted.

In contrast, tanker tensions in 2019 caused temporary spikes that faded quickly. Markets corrected, but once volatility subsided, stability returned. Even the oil surge following the Russia-Ukraine conflict in 2022 led to disruption, yet stronger foreign exchange reserves and improved fiscal management limited prolonged damage.

India’s macro position today is stronger than in earlier cycles. Foreign exchange reserves are substantial, the banking system is healthier, and external vulnerabilities are lower. A crisis scenario is unlikely under most reasonable oil paths.

But resilience does not remove repricing risk.

If oil volatility fades quickly, the market’s premium remains justified. If it lingers and bond yields rise meaningfully, investors may gradually demand lower multiples to compensate for higher uncertainty.

The central question is simple: will volatility pass, or will it persist long enough to change the cost of capital?

Oil may start the movement. The duration of uncertainty will decide how far it goes.
