Tehran's threat last week to seal the strait entirely if American strikes target Iranian power infrastructure was received in Western capitals as sabre-rattling, the kind of escalatory rhetoric that accompanies every modern conflict in the Persian Gulf. In New Delhi, it landed differently. India imports roughly eighty-five per cent of its crude oil. Nearly sixty per cent of that passes through the Strait of Hormuz — a channel barely fifty-six kilometres wide at its narrowest navigable point, flanked on one side by Iranian anti-ship missile batteries and on the other by the mountains of Oman. There is no alternative route. There is no strategic petroleum reserve of sufficient scale to cushion the blow. There is only the strait, and the increasingly fragile assumption that it will remain open.

The Indian government's response to the crisis has followed a pattern that students of South Block will recognise immediately: studied ambiguity masking genuine alarm. Officially, India has called for de-escalation, restraint, and dialogue — the diplomatic equivalent of a form letter. Unofficially, the petroleum ministry has been holding daily calls with the heads of Indian Oil, Bharat Petroleum, and Hindustan Petroleum since the second week of the conflict. The navy has quietly repositioned assets in the Arabian Sea. And the Reserve Bank of India, in what it described as a routine liquidity operation, injected an additional two hundred billion rupees into the banking system last Monday — a sum that would be unremarkable in normal times but that signals, to those who read such things, preparation for an oil shock.

The numbers are stark. India consumed approximately five and a half million barrels of oil per day in 2025. At current war-inflated prices of roughly one hundred and sixty dollars per barrel, that represents a daily import bill of nearly nine hundred million dollars — more than double the figure from eighteen months ago. The current account deficit, which the finance ministry had projected at three per cent of GDP for the fiscal year, is now tracking closer to five per cent. The rupee, which had been trading at eighty-seven to the dollar in January, touched ninety-four last week before RBI intervention steadied it at ninety-one.

These are not abstract figures. They translate directly into the price of cooking gas in a Dharavi kitchen, the cost of diesel for a farmer's tractor in Punjab, the freight charges embedded in every kilogram of rice and every metre of cloth that moves through India's domestic supply chain. When oil prices double, everything else follows — not immediately, not uniformly, but inexorably. The last time India faced an oil shock of comparable magnitude was 1990, when Iraq's invasion of Kuwait sent prices spiralling and India's foreign exchange reserves fell to a level that covered barely two weeks of imports. The economy was a fraction of its current size then. The lesson of 1990 — that India's prosperity rests on a foundation of imported energy that can be disrupted by events far beyond its borders — has not been forgotten in the corridors where policy is made, even if it has faded from public memory.

What distinguishes the present crisis from previous Gulf tensions is the absence of any credible diplomatic off-ramp. In past confrontations — the Tanker War of the 1980s, the post-9/11 period, the 2019 drone strikes on Saudi Aramco facilities — there existed a tacit understanding among all parties that the strait would remain open because closing it would be mutually destructive. Iran needed the revenue from its own oil exports, which transited the same waters. The Gulf states needed access to global markets. The Americans needed stable energy prices. This alignment of interests, however uncomfortable, functioned as a guarantee.

That alignment has shattered. Iran's oil exports have already been reduced to a trickle by sanctions and physical destruction of port infrastructure. The country's leadership, such as it is, no longer has an economic incentive to keep the strait open — it has only a military incentive to close it, or at least to make transit so dangerous that insurers refuse to cover tankers, which amounts to the same thing. Lloyd's of London has already designated the entirety of the Persian Gulf a war-risk zone. Insurance premiums for tanker voyages through the strait have increased by a factor of fifteen since January. Several major shipping lines have begun routing cargoes around the Cape of Good Hope, adding two weeks and roughly forty per cent to transportation costs.

India's strategic community has long discussed the Hormuz vulnerability in the abstract, usually at conferences where retired admirals present slides and serving bureaucrats nod thoughtfully before returning to more pressing matters. The Strategic Petroleum Reserve programme, announced with great fanfare in 2015, was meant to provide thirty-nine days of import cover by 2020. It currently provides approximately eleven. The diversification strategy — building pipelines from Russia, increasing imports from Africa and the Americas — has progressed, but not at the pace required to offset a Hormuz closure.

The uncomfortable truth, which Prime Minister Modi's government has so far avoided stating plainly, is that India's energy security now depends almost entirely on the decisions of military commanders in Tehran and Washington over whom New Delhi exercises zero influence. India is not a party to this conflict. It has no alliance with either side. It has carefully maintained relationships with both Iran and Israel, with both the Gulf monarchies and their adversaries, precisely to avoid being drawn into someone else's war. That strategic neutrality, the cornerstone of Indian foreign policy since independence, offers no protection against the secondary effects of a conflict that disrupts the physical infrastructure of global energy supply.

The domestic political implications are already materialising. The opposition has demanded an emergency session of Parliament. Petrol prices, which the government had managed to hold steady through the election season by absorbing losses at state-owned oil companies, can no longer be contained. The most recent revision added twelve rupees per litre — the largest single increase in a decade — and the petroleum ministry has signalled that further adjustments are likely. In a country where the price of fuel is felt immediately and personally by hundreds of millions of people, this is not merely an economic event. It is a political one.

What India requires, and what it is unlikely to receive, is time. Time to build out alternative supply routes. Time to accelerate the domestic solar and nuclear programmes that could, over the course of a decade, reduce dependence on imported hydrocarbons. Time to negotiate with Russia, with Saudi Arabia, with the Americans, for guaranteed supply arrangements that bypass the Gulf entirely. None of these solutions are available in the timeframe that the current crisis demands.

The *Ratna Shreya* eventually received her berth, discharged her cargo, and sailed east toward Singapore for her next charter. Her hull was carrying Indonesian coal, not Gulf crude — a small mercy. But in the port's operations centre, the screens tracking inbound tanker traffic told a different story. Of the fourteen crude carriers expected that week, three had diverted around the Cape. Two had been delayed by insurance renegotiations. One had simply disappeared from tracking systems altogether, its transponder dark, its fate and its cargo unknown.

India has always lived downstream of history's great convulsions, absorbing their consequences while possessing limited power to shape their course. The Strait of Hormuz is the latest in a long succession of chokepoints — geographic, economic, strategic — upon which the country's fate hinges but over which it holds no sovereignty. The question is no longer whether the strait will be affected by the Iran-Israel war. It is whether India can absorb the shock when it is.
