What Happened

Iran declared the Strait of Hormuz closed to hostile vessels in early March 2026 following military operations in the region, disrupting one of the world's most critical oil transit chokepoints through which approximately 20 million barrels per day of crude oil and petroleum products flow.
India's crude oil basket price surged from approximately $63 per barrel to around $114–146 per barrel within weeks of the closure, representing a sharp increase that placed significant pressure on the fiscal position of oil marketing companies (OMCs).
Approximately 30 India-bound vessels were reported stranded or held in maritime holding patterns during the peak disruption window, threatening refinery throughput schedules.
The Union Cabinet reduced excise duties on petrol and diesel by ₹10 per litre to absorb a portion of the price spike and shield retail consumers, while OMCs continued to procure crude at elevated international prices — generating reported losses of up to ₹1,000 crore per day across the sector.
India's Strategic Petroleum Reserves were reported to be approximately two-thirds full at the time of the crisis, providing a limited buffer estimated at around 9.5 days of consumption at government-managed reserves, with refinery-held stocks adding further coverage.

The Strait of Hormuz: A Critical Energy Chokepoint

The Strait of Hormuz is a 33-kilometre-wide waterway at its narrowest point, connecting the Persian Gulf to the Gulf of Oman between Iran and Oman. It is classified by the International Energy Agency (IEA) as the world's most important oil transit chokepoint. Approximately 20–21 million barrels per day of crude oil and petroleum products — roughly 20% of global seaborne oil trade — pass through the strait daily.

The strait has two 3.2-km-wide navigable shipping lanes (one inbound, one outbound) separated by a 3.2-km-wide median zone.
Major oil exporters transiting via Hormuz include Saudi Arabia, Iraq, UAE, Kuwait, and Iran itself.
India is uniquely exposed: approximately 85–90% of India's crude oil is imported, and around 50% of total crude imports — approximately 2.5–2.7 million barrels per day — transit the Strait of Hormuz.
Alternative routes around Hormuz include the Abu Dhabi Crude Oil Pipeline (ADCOP) to Fujairah and Saudi Arabia's East-West Pipeline to Yanbu, but combined capacity is far below normal Hormuz throughput.

Connection to this news: The 2026 disruption is a live test of the structural vulnerability that energy security planners have long warned about — India's near-total dependence on maritime routes that pass through a single chokepoint controlled by an adversarial state.

India's Strategic Petroleum Reserves (SPR): Capacity and Limitations

India maintains underground strategic petroleum reserves managed by Indian Strategic Petroleum Reserves Limited (ISPRL), a wholly owned subsidiary of the Oil Industry Development Board (OIDB) under the Ministry of Petroleum and Natural Gas.

Total operational SPR capacity: 5.33 Million Metric Tonnes (MMT) at three locations — Vishakhapatnam (1.33 MMT), Mangaluru (1.5 MMT), and Padur (2.5 MMT).
SPR provides approximately 9.5 days of supply coverage; combined with refinery-held stocks (approximately 64.5 days), total crude coverage is roughly 74 days.
The IEA recommends member countries hold at least 90 days of net import cover; India's actual coverage falls short of this benchmark.
Expansion is approved at Chandikhol (Odisha, 4 MMT) and Padur Phase II (Karnataka, 2.5 MMT) on a Public-Private Partnership mode.

Connection to this news: The crisis exposed the practical limit of India's SPR buffer. While reserves provided a short-term cushion, a prolonged Hormuz closure would exhaust government-managed stocks well within the crisis window, requiring more aggressive demand management or alternative sourcing.

Fuel Pricing in India: Administered vs. Market-Linked Mechanisms

India moved from a fully administered fuel pricing regime to dynamic pricing for petrol (June 2010) and diesel (October 2014), theoretically allowing OMCs to revise prices daily in line with international crude benchmarks and exchange rates.

In practice, retail fuel prices are set by state-owned OMCs — Indian Oil Corporation (IOC), Bharat Petroleum Corporation Ltd. (BPCL), and Hindustan Petroleum Corporation Ltd. (HPCL) — and have often been held stable for extended periods for political-economic reasons.
The excise duty component in petrol and diesel is a significant lever: the Union government collects approximately ₹19.90/litre on petrol and ₹15.80/litre on diesel (post the recent cut), but these rates have been revised multiple times.
The difference between international crude cost and retail selling price is absorbed by OMCs as under-recoveries, which may be compensated through budgetary support or cross-subsidisation.
States levy additional VAT on fuel; combined central + state taxes account for 45–55% of the retail price depending on the state.

Connection to this news: The decision to reduce excise duties rather than pass on the Hormuz-driven price spike represents a deliberate policy choice to use fiscal space as a buffer — compressing government revenue to protect household consumption and manage inflation expectations.

India's Crude Oil Import Diversification: The Russia Factor

Following the Russia-Ukraine conflict in 2022, India significantly increased crude purchases from Russia, taking advantage of discounted prices available through bilateral arrangements.

Russia became India's single largest crude supplier from 2022 onward, accounting for approximately one-third of total crude imports as of 2026.
Russian crude is transported via maritime routes that largely bypass the Strait of Hormuz (routing through the Indian Ocean via Cape of Good Hope alternatives or northward routes).
However, because crude oil is a globally priced commodity benchmarked to Brent and Dubai Fateh, even discounted Russian barrels are affected by global price spikes — the discount is relative to a higher global benchmark.
India's remaining crude imports continue to come from the Middle East (Iraq, Saudi Arabia, UAE), all of which primarily route through Hormuz.

Connection to this news: The Russia pivot reduced but did not eliminate India's Hormuz exposure. A prolonged closure directly threatens the 50% of imports still transiting the strait, while global price effects pass through regardless of sourcing origin.
