Iran-Israel escalation threatens India's oil lifeline through Strait of Hormuz

There is no backup plan when 20 million barrels pass daily through a single strait.
India's oil supply depends almost entirely on the Strait of Hormuz, which now sits at the center of direct Israeli-Iranian military conflict.

On February 28th, a decades-long shadow conflict between Israel and Iran crossed into open warfare, sending tremors far beyond the Middle East to the shores of a nation that imports two-thirds of its crude oil through the narrow waterway now at the center of the crisis. India, which has long balanced careful diplomacy with both parties, finds that geography is a more powerful force than goodwill — and that the Strait of Hormuz, through which 20 million barrels of oil pass daily, is not merely a shipping lane but the structural spine of its economic stability. What unfolds in a narrow channel between Oman and Iran may determine whether inflation rises, interest rates hold, and the ambitions of the world's most populous nation are deferred once again by forces beyond its borders.

  • Israel launched pre-emptive strikes on Iran on February 28th, including near the compound of Supreme Leader Khamenei, and Iran responded within hours with direct missile fire — ending decades of proxy conflict and opening a new, more dangerous chapter.
  • The Strait of Hormuz, carrying 20 million barrels of oil daily with no viable alternative route, is now encircled by active military confrontation, and Iran's naval commanders have already warned they retain the power to close it.
  • Houthi forces in Yemen, who had paused Red Sea attacks under a U.S.-brokered deal, signaled they would resume strikes on commercial shipping within hours in solidarity with Iran, compounding the threat to global supply chains.
  • India, which channels roughly two-thirds of its crude imports and half its LNG through Hormuz, faces the prospect of simultaneous supply shocks, price spikes, and inflation reversal at a moment when its economy had been cautiously stabilizing.
  • The Reserve Bank of India's anticipated rate cuts, the government's fuel subsidy calculus, infrastructure spending plans, and fiscal deficit targets all hang in the balance — a cascade of consequences flowing from a single chokepoint.

On February 28th, the long-running covert war between Israel and Iran broke into the open. Backed by the United States, Israel launched pre-emptive strikes on Iranian targets, including sites near the offices of Supreme Leader Khamenei. Iran responded within hours with missile fire, lighting up northern Israeli cities as air defenses scrambled to intercept the incoming barrage. Decades of proxy skirmishes and clandestine operations had finally given way to direct military confrontation — and thousands of miles away, New Delhi was already feeling the tremors.

India's exposure is structural, not merely political. Two-thirds of its imported crude oil and roughly half its liquefied natural gas travel through the Strait of Hormuz, the narrow channel separating Oman from Iran. On any given day, 20 million barrels of oil pass through it — nearly 30 percent of all seaborne oil trade globally. Around 70 percent of that volume heads to Asia, with India among the most dependent recipients. There are no realistic alternatives: pipeline capacity can absorb only 4.2 million barrels per day, and all LNG exports from Qatar and the UAE also depend on Hormuz, with no bypass available.

The threat is not theoretical. Iran's Revolutionary Guard naval commander had warned just weeks earlier that Tehran could close the strait if provoked. Meanwhile, Houthi forces in Yemen — who had paused Red Sea shipping attacks under a Trump administration agreement — signaled they would resume strikes on commercial vessels within hours in support of Iran.

India has navigated Hormuz crises before. In 2019, after tankers were damaged by explosions near the strait, the Indian Navy escorted vessels through the channel and New Delhi opened diplomatic channels with Tehran. India even participated in the 2020 Hormuz Peace Initiative. But diplomacy has limits when missiles are already in the air.

A sustained disruption would send shockwaves through India's economy: oil prices would spike, inflation would reverse its recent decline, and the Reserve Bank of India would face pressure to hold or raise interest rates rather than cut them. The government would be forced to choose between absorbing enormous fuel subsidy costs or passing them to consumers. Infrastructure spending and fiscal targets could both slip. The entire cascade originates from one narrow waterway — one where, for the first time in a long while, two adversaries are trading direct blows with no clear off-ramp in sight.

On February 28th, the shadow war between Israel and Iran moved into the open. With American backing, Israel launched pre-emptive strikes against Iranian targets, including near the offices of Supreme Leader Ayatollah Ali Khamenei. Within hours, Iran fired missiles back at Israel. Northern Israeli cities lit up with explosions as air defenses worked to intercept the incoming fire. The cycle of tit-for-tat attacks that had simmered for decades through proxies and clandestine operations had erupted into direct military confrontation, and the reverberations were already being felt thousands of miles away in New Delhi.

India's predicament is acute. The country maintains diplomatic ties with both Israel and Iran, but that careful balance offers little protection against what comes next. What matters far more than politics is physics: roughly two-thirds of India's imported crude oil and about half its liquefied natural gas flow through the Strait of Hormuz, the narrow waterway separating Oman from Iran. That strait is now at the center of a military crisis. The Strait of Hormuz is not merely important—it is the world's most critical oil chokepoint. On an ordinary day, 20 million barrels of crude move through it. Nearly 30 percent of all seaborne oil trade globally passes through this channel. Around 70 percent of that oil heads to Asia, with China, India, Japan, and South Korea accounting for two-thirds of all shipments. There are no realistic alternatives. Only 4.2 million barrels per day can be rerouted through pipelines. All liquefied natural gas exports from Qatar and the United Arab Emirates also depend on Hormuz, representing roughly 20 percent of global LNG trade, with no practical bypass routes available.

The threat is not hypothetical. Just weeks before the February escalation, Alireza Tangsiri, commander of Iran's Revolutionary Guard naval forces, warned that Tehran could close the Strait if it deemed necessary. "We can close the Hormuz Strait but are not doing so," he said. "However, if the enemy comes to disrupt us, we will review our policy." Meanwhile, Iranian-backed Houthi rebels in Yemen—who had paused their attacks on Red Sea shipping under a Trump administration deal—signaled they would resume missile and drone strikes on commercial vessels and Israeli targets in support of Iran. Senior Houthi officials told the Associated Press that the first attack could come within hours.

India has been here before. In 2019, when tensions spiked around Hormuz after two oil tankers were damaged by explosions, the International Energy Agency identified India as likely to suffer among the worst consequences. The Indian Navy escorted vessels through the strait. New Delhi opened diplomatic channels with Tehran. India even participated in a 2020 meeting in Tehran on the Hormuz Peace Initiative, an effort to stabilize one of the world's busiest shipping lanes. But diplomatic goodwill offers limited protection against military escalation.

A sustained disruption to Hormuz would ripple through India's entire economy. Oil prices would spike. Supply would tighten. Inflation, which has been easing in recent months, would reverse course. The Reserve Bank of India, which many expect will cut interest rates by year's end, would face pressure to hold rates steady or raise them. The government, which already subsidizes fuel heavily, would face a choice between absorbing massive costs or passing them to consumers. Infrastructure spending could be curtailed. Fiscal deficit targets could slip. The cascade of consequences flows from a single chokepoint: a narrow stretch of water where 20 million barrels pass daily, where there is no backup plan, and where two adversaries are now trading direct military blows.

Shipping through Hormuz has never fully stopped, not even during the 1984 Tanker War when Iran and Iraq attacked each other's tankers relentlessly. A complete closure would harm Iran as much as its adversaries, since China and India—major buyers of Iranian energy—would retaliate. But a serious disruption, lasting weeks or months, is entirely plausible. And for India, which has spent years diversifying away from Russian oil under American pressure and now depends even more heavily on Middle Eastern suppliers, the timing could not be worse. The country is watching developments in the Strait of Hormuz with the intensity of someone watching a single thread that holds up the entire structure.

We can close the Hormuz Strait but are not doing so. However, if the enemy comes to disrupt us, we will review our policy.
— Alireza Tangsiri, commander of Iran's Revolutionary Guard naval forces

Why does India care more about this than, say, Europe does?

Model

Because of where the oil goes. Seventy percent of everything through Hormuz heads to Asia. India imports two-thirds of its crude through that channel. Europe has alternatives—pipelines, different suppliers, strategic reserves. India doesn't have those luxuries.

Inventor

But Iran wouldn't actually close the Strait, would it? That would hurt Iran too.

Model

Exactly. Which is why a full closure is unlikely. But a disruption—weeks of attacks, shipping delays, insurance costs spiking—that's very possible. And for India's economy, even a partial slowdown in supply means higher prices immediately.

Inventor

What's the connection to the Houthis restarting attacks?

Model

The Houthis had stopped hitting ships in the Red Sea under a Trump deal. Now they're signaling they'll restart. That's a second chokepoint under threat. If both Hormuz and the Red Sea routes face disruptions, India's oil has nowhere to go.

Inventor

Could India just buy from somewhere else?

Model

Not quickly. Iraq, Saudi Arabia, the UAE, Kuwait—all their oil goes through Hormuz too. India was already trying to reduce Russian purchases under US pressure. There's no spare capacity elsewhere that can absorb Indian demand.

Inventor

What happens to India's economy if prices spike?

Model

Inflation rises, which means the central bank can't cut interest rates when the economy needs stimulus. The government's fuel subsidies become unsustainable. Infrastructure projects get delayed. It's a cascade—one chokepoint, one military escalation, and suddenly fiscal policy is constrained for months.

Inventor

Has India prepared for this scenario?

Model

They've tried. Diplomatic talks with Iran, participation in regional stability initiatives. But diplomacy doesn't stop missiles. India's real vulnerability is structural: it needs energy it can't produce, and that energy flows through a strait controlled by a country it's now watching very carefully.
