Geopolitics & the Market: How US-Iran Tensions Are Shaping Indian Equities

If you've been watching the markets over the last few months and wondering why markets feel so jittery, this article is for you.

Because the answer isn't in quarterly earnings or RBI policy. It's sitting in a narrow waterway between Iran and the Arabian Peninsula called the Strait of Hormuz.

Let's break down what happened and what it actually means for your investments.

A conflict that moved faster than analysis

Things escalated quickly after February 28, 2026, when the US and Israel carried out coordinated strikes on Iranian military infrastructure. Within days, the conflict had widened into a regional confrontation, retaliatory missile and drone attacks, emergency UN Security Council sessions, and evacuations across parts of the Middle East.

The death of Iran's Supreme Leader Ayatollah Ali Khamenei added another layer of instability. Markets can usually process bad news. What they struggle with is open-ended uncertainty, especially when nobody knows what the next move will look like.

That uncertainty became far more serious once disruptions around the Strait of Hormuz began.

And that’s where India enters the picture.

Why is India vulnerable here?

This is the part that often gets reduced to a headline about “higher crude prices,” but the implications are much broader.

India imports roughly 4.5 to 5 million barrels of crude oil every day, and a large chunk of that comes through the Gulf region. The Strait of Hormuz alone carries close to 20% of the global oil supply.

So when tensions rise there, the impact doesn’t stay confined to energy markets for long.

It eventually shows up everywhere: Fuel prices, transport costs, inflation, company margins, even household spending.

A $10 rise in crude increases India’s monthly import bill by around $1.5 billion and pushes inflation higher. Once oil started climbing after the conflict, investors quickly realised this wasn’t going to be a short-term market scare. It had the potential to become a broader macroeconomic problem.

What markets actually did?

Financial markets don't wait for clarity. They price uncertainty immediately.

Indian equities dropped close to 4% in the first couple of trading sessions after the conflict escalated. But the more important signal came from foreign investors.

By late March, FIIs had already pulled out over ₹1.12 trillion from Indian equities, one of the largest monthly outflows on record.

At the same time, the rupee slid to a fresh low against the dollar, while Brent crude moved above $100 a barrel.

Currency markets tend to reflect fear before equity markets fully do. And when oil, the dollar, and foreign outflows all move together, emerging markets like India usually feel the pressure quickly.

The sector story: Losers, winners, and the complicated middle

This wasn’t one of those situations where “the whole market” moved in the same direction.

Certain sectors were clearly more exposed.

Oil marketing companies, airlines, auto stocks, consumer durables, and paint companies all came under pressure because higher crude prices directly affect their costs.

Paint companies are a good example. A meaningful portion of their raw materials comes from crude-linked derivatives, so when oil prices spike, margins tighten pretty quickly.

There were obvious comparisons with 2022 after Russia invaded Ukraine. Back then, too, FIIs sold aggressively, and markets corrected sharply as energy prices surged.

But not everything struggled.

Defence stocks performed well. Metals gained because of supply concerns. And gold rallied as investors moved toward safer assets.

The defence story is particularly interesting because it isn’t just a short-term reaction trade anymore. India’s defence spending has been steadily rising, and policies favouring domestic manufacturing are creating long-term visibility for companies in the sector.

Ironically, periods of geopolitical instability often become structural tailwinds for defence businesses.

Analysts started cutting expectations.

As the conflict dragged on, brokerages began revising their assumptions.

Average Nifty targets were gradually lowered as analysts started pricing in slower earnings growth, inflation pressure, and the possibility of prolonged energy disruption.

That doesn’t necessarily mean panic. It just reflects the reality that higher oil prices make things harder for an oil-importing economy like India.

At the same time, some global firms still maintained a constructive medium-term outlook, arguing that India’s broader growth story remained intact once the immediate uncertainty eased.

That split in opinion is still visible today.

Where things stand now

As of late May, there are signs that diplomacy is moving in the right direction, although slowly.

There’s reportedly a framework in place to extend the ceasefire while negotiations continue, and oil prices have cooled from their peak levels. Indian markets have also stabilised somewhat alongside that move.

But nobody seems fully convinced the situation is resolved.

Iran has said a final agreement is still not close, while US officials continue to keep military options on the table if talks fail.

Which means markets are still trading less on fundamentals and more on headlines from the Middle East.

And for India, that connection is difficult to ignore, as oil remains a central part of the economic equation.

So what should investors take from all this?

A few things stand out.

First, geopolitical selloffs are usually sharp, but they’re not always permanent. Markets can recover very quickly once uncertainty begins to fade, as the April rally showed.

Second, different sectors react very differently to rising geopolitical tensions. Businesses closely tied to oil prices usually come under pressure, while sectors such as defence, metals, and gold often see investor interest pick up. In periods like this, understanding where your portfolio is exposed matters far more than simply tracking the Nifty every day.

And third, it’s worth watching the rupee, crude oil, and foreign investor flows just as closely as the Nifty itself. Those indicators often reveal more about the underlying pressure in the system.

Most importantly, though, this episode has been a reminder that global events are no longer “far away” from Indian markets.

What happens around the Strait of Hormuz eventually affects inflation, corporate profitability, currency stability, and consumer spending here at home.

The investors who navigated this period best probably weren’t the ones who perfectly predicted the market.

They were the ones who understood where the risks were and positioned themselves accordingly.

And honestly, that’s usually more valuable than trying to forecast every headline.
