US-Iran war impact: India adds new suppliers amid crude supply disruption, but only 5 nations control imports — Check
Amid supply disruptions linked to the prolonged conflict between the United States and Iran and the closure of the Strait of Hormuz route since March 1, 2026, India expanded its crude oil sourcing to 31 supplier countries between March and August 2026, up from 24 in the preceding six months
Despite the larger number of suppliers, overall import concentration rose, with Russia alone accounting for roughly 47% of India's crude imports — pushing the supplier base into a "high-risk" concentration range by standard diversification metrics
Of the ten new supplier countries added, nine together contributed only about 1.4% of total crude imports; Venezuela was the exception, contributing close to 5%
Supplies from traditional partners fell: Saudi Arabia's volumes dropped by roughly 300,000 barrels per day and United States supplies fell by about 200,000 barrels per day during the disruption period
India's Crude Oil Import Dependency and Energy Security Architecture
India imports over 80% of its crude oil requirement (import dependency ratio of roughly 81-88% in recent years), making crude sourcing diversification a core pillar of national energy security. The Ministry of Petroleum and Natural Gas and public sector oil marketing companies (IOC, BPCL, HPCL) manage the sourcing mix, while the government maintains Strategic Petroleum Reserves (SPR) as a buffer against supply shocks.
Key Details
- India's Strategic Petroleum Reserve, managed by Indian Strategic Petroleum Reserves Limited (ISPRL), has underground rock cavern storage at Visakhapatnam, Mangalore, and Padur with a total capacity of about 5.33 million tonnes, covering roughly 9-10 days of net crude imports at full capacity
- Including storage held by state-run oil companies, India's total national storage (crude plus refined products) covers around 74 days of net imports — still below the International Energy Agency's (IEA) benchmark of 90 days of net oil import cover for member countries (India is an IEA Association country, not a full member)
- Expansion of SPR capacity to about 6.5 million tonnes is under way to improve crisis resilience
- A concentration ratio where a small number of suppliers dominate total imports (e.g., top 5 countries controlling the bulk of the basket) signals higher vulnerability to any single-country supply shock, even when the total number of supplier countries rises
The article's finding — more supplier countries but higher concentration, driven by Russia's dominant 47% share — is a textbook illustration of the difference between "diversification by count" and "diversification by risk-weighted concentration," a distinction relevant to GS3 energy security questions.
Strait of Hormuz and Chokepoint Geography in India's Energy Trade
The Strait of Hormuz, between Iran and Oman, is the world's most critical oil chokepoint, through which roughly a fifth of global oil trade transits. Its closure or disruption directly affects India, historically a major importer of Gulf crude (Iraq, Saudi Arabia, UAE) that transits this route.
Key Details
- The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Arabian Sea; alternative routes (e.g., Saudi Arabia's East-West Pipeline to the Red Sea) exist but have limited capacity
- India historically sourced roughly 40-60% of its crude from Gulf/West Asian producers transiting the Strait before the recent Russia-driven diversification since 2022
- Russia's share in India's crude basket rose sharply after 2022 Western sanctions redirected discounted Russian Urals crude to Asian buyers (India and China); by 2026 Russia had become India's single largest crude supplier
- Other global chokepoints relevant to India's trade include the Strait of Malacca, Bab-el-Mandeb, and the Suez Canal
The Hormuz closure since March 2026 forced Indian refiners to look beyond traditional Gulf suppliers, explaining both the jump in supplier-country count and continued heavy reliance on Russian crude, which does not transit the Strait.
India's Non-Aligned Sourcing Strategy Amid US-Iran Tensions
India has historically balanced its crude purchases pragmatically across geopolitical blocs — continuing to buy Russian crude despite Western sanctions pressure while maintaining energy ties with the US, Gulf states, and now expanding to newer suppliers like Venezuela and African/Latin American producers, consistent with its broader "strategic autonomy" foreign policy posture.
Key Details
- India does not participate in unilateral Western sanctions regimes unless mandated by UN Security Council resolutions, allowing continued Russian crude purchases (subject to the G7 price cap mechanism on Russian oil)
- The G7 price cap on Russian seaborne crude was set at $60/barrel (2022) to limit Russian oil revenue while keeping global supply flowing
- Venezuela's crude exports to India have fluctuated based on shifting US sanctions waivers on Venezuelan oil (PDVSA)
The diversification pattern in the article, adding marginal suppliers like Venezuela while Russia's share still grows, reflects India's consistent policy of sourcing energy on commercial and strategic-autonomy grounds rather than aligning with any single geopolitical bloc.
- Number of crude oil supplier countries for India: 31 (March-August 2026), up from 24 in the preceding six months
- Russia's share of India's crude imports: approximately 47%
- New suppliers added: 10; nine of them together contributed just 1.4% of imports; Venezuela alone contributed nearly 5%
- Saudi Arabia supply drop: ~300,000 barrels/day; US supply drop: ~200,000 barrels/day
- India's Strategic Petroleum Reserve capacity: ~5.33 million tonnes (expansion target ~6.5 million tonnes); covers ~9-10 days of net imports at full capacity
- Total national oil storage cover (SPR + OMC stocks): ~74 days of net imports, versus IEA benchmark of 90 days
- India's crude oil import dependency: over 80% of domestic requirement
- Strait of Hormuz closure to shipping: since March 1, 2026
