Strait of Hormuz Crisis: How China's Falling Crude Imports Are Easing India's Oil Shock

Location and geography: The Strait of Hormuz is a narrow sea passage that connects the Persian Gulf to the Gulf of Oman and onward to the Arabian Sea. It lies between Iran to the north and Oman (its Musandam exclave) and the United Arab Emirates to the south. At its narrowest point it is only about 33 kilometres wide, with even narrower shipping lanes for inbound and outbound vessels.

Why it is a "chokepoint": In geopolitics, a chokepoint is a narrow channel along a widely used global sea route that a single actor can block or threaten, disproportionately affecting world trade. The Strait of Hormuz is the single most important oil chokepoint on earth because there is no large-scale alternative route. Around 20% of the world's total oil supply and roughly one-quarter of seaborne oil trade — about 21 million barrels of crude and products a day — pass through it, along with major volumes of LNG (especially from Qatar).

Who depends on it: The major Gulf oil exporters — Saudi Arabia, Iraq, the UAE, Kuwait, Qatar and Iran — ship most of their crude through this route. The biggest buyers are in Asia. In 2025, of the nearly 15 mbd of crude that passed through the Strait, China and India together received about 44% of the exports, underlining how heavily Asia depends on this single waterway.

The conflict trigger (factual, neutral): On 28 February 2026, military strikes on Iran by the United States and Israel led to a sharp escalation in West Asia. In response, the Strait of Hormuz was effectively closed to normal traffic. Marine insurance premiums shot up, tankers avoided the route, and crude loadings inside the Gulf fell to extremely low levels.

Scale of disruption: The International Energy Agency (IEA) described the situation as one of the largest supply disruptions in the history of the global oil market, with an estimated structural loss of around 8 mbd of supply from the Middle East. Even after intermittent ceasefire efforts (an early ceasefire was attempted in April 2026, and a fresh memorandum of understanding was under negotiation by late May), shipping traffic through the Strait remained far below pre-war levels.

Why prices did not stay above $150: Prices spiked above $150 per barrel during the initial panic but then eased to a $100–$120 band. Analysts attribute this partly to coordinated Strategic Petroleum Reserve (SPR) releases by several countries — particularly the United States — and, importantly, to the absence of Chinese buying from the market, which removed a major source of demand pressure.

The scale of China's pullback: China's crude imports in May 2026 were tracking near 6.6 mbd, the lowest level since 2016. Its refinery crude intake fell to around 13.5 mbd, down nearly 1.92 mbd against the 2025 average, meaning Chinese refiners cut their processing ("run rates") significantly.

Why China cut back: Several reasons combine here. First, China holds very large commercial oil inventories and strategic reserves, so it can draw down stored crude instead of importing at high prices. Second, high global fuel prices and relatively weak ("tepid") domestic economic activity have dampened China's oil demand. Third, China is accelerating its energy transition toward electric mobility and renewables, structurally slowing its oil demand growth.

How this helps India (the core insight): Because China stepped back as a buyer, crude from regions not affected by the Strait's closure — Russia, West Africa, the Atlantic Basin and non-Hormuz suppliers — became available in the broader Asian market. India, along with South Korea, Japan, Thailand and Singapore, was able to "snap up" these freed-up barrels. This blunted the supply crunch and prevented prices from climbing even higher. In effect, a reluctant Chinese buyer acted as an unintended cushion for India's energy security during the crisis.

India's import dependency: India is the world's third-largest consumer and importer of crude oil (after the United States and China). It imports more than 88% of the crude it needs, consuming roughly 5–5.5 mbd. This makes India structurally vulnerable to any global price spike or supply shock. Crude oil is India's single largest merchandise import item.

Exposure to the Strait of Hormuz: A large share of India's crude and LPG passes through Hormuz. Before the crisis, estimates of India's crude flowing through the Strait ranged from about 40% to over 50%, and exposure had risen as Russian flows fell earlier in 2026. India's LPG dependence is even more concentrated: it imports around 60% of its LPG, of which nearly 90% normally moves through Hormuz.

The diversification cushion: Over recent years India has reduced single-route risk by importing from around 40 countries. Crucially, Russian crude — which arrives via routes that bypass Hormuz — rose from less than 2% of India's imports before 2022 to roughly 35–38% by 2025–26. During the current crisis, around 70% of India's crude imports were reported to be arriving through routes other than the Strait of Hormuz. India has not imported Iranian oil since 2020.

The current account deficit (CAD) — the main channel: The CAD measures the gap between what India earns from and pays to the rest of the world on trade, services and transfers. Since crude is India's biggest import, higher oil prices enlarge the import bill and widen the CAD. According to a Nomura assessment, every 10% rise in oil prices typically widens India's CAD by about 0.4% of GDP. The Indian Express report notes that India imports 1.8–2 billion barrels of oil a year, so every $1-per-barrel rise can add up to $2 billion to the annual oil import bill.

The rupee and capital flows: A wider CAD increases demand for foreign currency (dollars) to pay for imports, which puts downward pressure on the rupee. A weaker rupee, in turn, makes imported crude even costlier in rupee terms — a feedback loop. High uncertainty can also trigger outflows by foreign portfolio investors (FPIs), adding further pressure on the rupee and markets.

Inflation: Crude oil feeds into petrol, diesel, LPG, fertilisers, plastics and transport costs. Higher oil prices therefore raise both direct fuel inflation and the cost of goods across the economy ("second-round" or pass-through effects), squeezing households.

The fiscal channel: If the government cuts excise duties or absorbs price rises to protect consumers, it loses revenue. Higher fuel, fertiliser and cooking-gas subsidy costs can also widen the fiscal deficit. This is why oil shocks simultaneously stress the external account, the currency, prices and the budget.

What an SPR is: A Strategic Petroleum Reserve is an emergency stockpile of crude oil maintained by the government to be used during supply disruptions, when imports are interrupted or prices spike. It is separate from the commercial stocks held by oil companies.

India's SPR set-up: India's SPRs are managed by Indian Strategic Petroleum Reserves Limited (ISPRL), a special purpose vehicle set up in 2004, working under the Oil Industry Development Board (OIDB) and the Ministry of Petroleum and Natural Gas. Crude is stored in underground rock caverns near the coast, which reduce evaporation losses and allow quick mobilisation to nearby refineries.

Phase-I capacity and locations: The existing (Phase-I) capacity is about 5.33 million metric tonnes (MMT) across three sites — Visakhapatnam (Andhra Pradesh), Mangaluru (Karnataka) and Padur (Karnataka). At full capacity this provides roughly 9.5 days of India's crude requirement. Including the commercial storage of oil marketing companies (about 64.5 days), India's total national storage capacity is around 74 days of net imports.

Phase-II expansion: A Phase-II expansion of about 6.5 MMT has been approved, with new facilities planned at Chandikhol (Odisha, 4 MMT) and an additional cavern at Padur (2.5 MMT). India also allows part of its SPR to be used commercially (for example, an arrangement allowing ADNOC of the UAE to store crude at Mangaluru), with the government retaining the first right over the crude in an emergency.

The benchmark gap: As an Associate Member of the IEA, India is guided by the IEA norm of holding reserves equal to about 90 days of net oil imports. India's strategic reserves alone (about 9.5 days) are far short of this benchmark, which is why SPR expansion is treated as a national energy-security priority.

Source diversification: By spreading purchases across roughly 40 countries and sharply increasing non-Hormuz Russian crude (bought at a discount to Brent), India has reduced its dependence on any single supplier or shipping route. This diversification is what allowed Indian refiners to keep buying through the current crisis.

Refining capacity: India operates 22 refineries and is among the world's largest refining hubs. During the crisis, Indian refineries ran at high utilisation — in some cases above 100% of rated capacity — to maximise the supply of petroleum products. India's network of about one lakh (100,000) fuel retail outlets has remained functional with adequate stocks.

Why this matters for UPSC: It illustrates the concept of "strategic autonomy" in energy — turning a vulnerability (high import dependence on one chokepoint) into a more manageable risk through diversification, refining strength, strategic reserves and diplomacy.

Monitoring and assurance: A 24×7 control room was set up to track petroleum stocks and fuel availability across the country, and the Ministry of Petroleum and Natural Gas repeatedly assured uninterrupted and affordable supply of petroleum products.

Demand and allocation management: A Natural Gas Control Order was issued on 9 March 2026 under the Essential Commodities Act, 1955, to ration and prioritise gas supply — protecting domestic piped gas (PNG) and CNG for vehicles while allowing controlled reductions for some industrial and large users.

Trade and logistics steps: The government cut excise duties on motor fuels, granted customs duty exemptions on certain petroleum products, eased port procedures to handle re-routed cargoes, and issued an order to streamline natural-gas and petroleum-products pipeline laying to strengthen long-term infrastructure.

Diplomacy and sourcing: India intensified procurement of non-Hormuz crude (US, Russia, West Africa, Venezuela) and pursued diplomatic measures for the safe passage of Indian-flagged vessels and the welfare of Indian seafarers in the region.

Energy security defined: Energy security means reliable, affordable and uninterrupted access to energy. Its pillars are availability (physical supply), affordability (price), accessibility (infrastructure and routes), and sustainability (transition to cleaner sources). The Hormuz crisis stresses the first three pillars at once.

Role of OPEC and OPEC+: The Organization of the Petroleum Exporting Countries (OPEC) and its wider grouping with allies such as Russia (OPEC+) coordinate production levels and strongly influence global prices. In a Hormuz-type crisis, even spare OPEC+ capacity is of limited use if the crude cannot physically exit the Gulf.

The way forward for India: Key long-term steps include accelerating SPR expansion toward the IEA's 90-day benchmark; deepening source and route diversification; expanding domestic exploration and production; scaling up renewables, green hydrogen, ethanol blending and electric mobility to cut oil dependence; and building bypass pipeline and port infrastructure. Until oil flows through the Strait normalise, India's exposure remains a live risk — and a recovery in Chinese demand could quickly tighten Asian supply again.
