What Happened
- Indian refiners have resumed purchasing Iranian crude oil and LPG following a temporary US sanctions waiver granted in March 2026 amid escalating tensions in West Asia.
- Indian Oil Corporation (IOC) purchased its first cargo of Iranian LPG in nearly eight years — since 2018 when India stopped Iranian oil imports under US maximum pressure sanctions.
- A sanctioned tanker carrying Iranian LPG is expected at the west coast port of Mangalore in the last week of March 2026, with the cargo comprising liquefied petroleum gas to help address a domestic supply shortfall.
- Iran's Foreign Minister Abbas Araghchi stated that vessels from "friendly" nations, including India, would be permitted safe passage through the Strait of Hormuz, alleviating concerns about energy supply disruptions caused by the ongoing West Asia conflict.
- The move comes as supply from other Gulf sources has been disrupted, raising LPG and crude prices; India imports roughly 85% of its petroleum needs.

India-Iran Energy Relations and the Sanctions History
India and Iran have had a complex but significant energy relationship. At its peak, Iran accounted for roughly 11.5% of India's total crude oil imports. Under the 2015 JCPOA (Joint Comprehensive Plan of Action), US sanctions were eased, and India rapidly expanded Iranian crude purchases. However, after the US withdrew from the JCPOA in 2018 and reimposed "maximum pressure" sanctions, India progressively wound down Iranian crude imports to zero by 2019, under pressure from Washington.
- India was one of Iran's largest crude oil customers before 2019.
- The Rupee-Rial payment mechanism (direct bilateral currency trade) was developed to avoid dollar-denominated transactions during the pre-2019 sanctions period.
- Iran was also the supplier for the Chabahar Port project — India's strategic gateway to Afghanistan and Central Asia, which has been developed by India to bypass Pakistan.
- The US issued country-specific waivers (Strategic Petroleum Releases) to eight countries, including India, during the 2018–2019 transition period before full sanctions came into force.
- Iran holds the world's second-largest natural gas reserves and fourth-largest oil reserves.
Connection to this news: The current resumption is the first tangible energy trade revival since 2019, enabled by a temporary US waiver reflecting Washington's own interest in calming energy markets amid the West Asia conflict — a direct example of sanctions diplomacy shaping India's energy procurement.
The Strait of Hormuz and India's Energy Vulnerability
The Strait of Hormuz is the world's most critical maritime chokepoint for energy. Located between Iran and Oman, it connects the Persian Gulf to the Gulf of Oman and Arabian Sea. At its narrowest point it is only about 21 nautical miles wide.
- Over 20% of global oil and roughly one-fifth of global LNG trade passes through the Strait of Hormuz annually.
- Approximately 53% of India's crude oil comes from Gulf suppliers (Iraq, Saudi Arabia, UAE, Kuwait); disruption at Hormuz directly threatens over one-third of India's total oil imports.
- Qatar — India's primary LNG supplier — ships its gas through the Strait; Qatar accounts for roughly 50% of India's LNG requirements.
- As of early 2025, India imported around 2.0–2.1 million barrels per day through this corridor out of a total ~5.5 million barrels per day consumed.
- Alternative routes (around the Cape of Good Hope) would add weeks to transit time and significantly increase costs.
Connection to this news: Iran's threat to restrict passage, and its subsequent conditional reprieve for "friendly" nations, underlines how India's energy security is structurally vulnerable to geopolitical developments in the Persian Gulf — making diversification and naval presence imperative.
India's Energy Security Architecture
Energy security is defined as the reliable, affordable, and sustainable supply of energy. India's energy security framework has evolved from a supply-diversification focus to a more strategic posture involving supply-chain resilience, strategic petroleum reserves, and multi-vector diplomacy.
- India is the world's third-largest oil importer and consumer (after the US and China).
- India imports ~85–87% of its crude oil requirements; domestic production meets only 13-15%.
- Strategic Petroleum Reserves (SPR): India has underground caverns at Visakhapatnam, Mangaluru, and Padur with a combined capacity of ~5 million metric tonnes (approximately 9.5 days of import cover).
- India's Integrated Energy Policy (IEP) and the National Energy Policy promote diversification across suppliers and sources (solar, nuclear, gas, coal).
- The India Energy Security Scenarios (IESS) model guides long-term planning.
- India is a founding member of the International Solar Alliance (ISA), established in 2015 at COP21.
Connection to this news: Resuming Iranian crude imports — even under a temporary waiver — is a pragmatic measure to reduce supply-side pressure from Gulf disruptions, consistent with India's strategy of multi-source energy procurement.
