A short-term shift in US sanctions policy is creating a potential reopening of India’s oil trade with Iran, a relationship that had been effectively shut since 2019. The development follows Washington’s decision to allow a 30-day window for the sale of Iranian crude already loaded on vessels, a move aimed at easing global supply pressures triggered by the ongoing conflict in West Asia.

As per the US Treasury’s Office of Foreign Assets Control, the waiver permits transactions involving Iranian oil loaded before March 20 and discharged by April 19. This is a narrowly defined relaxation, targeting cargoes already at sea rather than enabling fresh exports.

For India, this creates a unique but time-bound opportunity. Prior to the reimposition of US sanctions in 2018, Iran was among India’s key crude suppliers, accounting for over 11 percent of total imports at its peak. The cessation of imports in 2019 forced refiners to pivot toward alternative suppliers including the Middle East, the United States, and more recently, Russia.

The current waiver comes at a time when global oil markets are under stress due to disruptions in the Strait of Hormuz and broader regional instability. Estimates suggest that between 130 million and 170 million barrels of Iranian crude are currently stranded at sea, representing a meaningful pool of supply that could temporarily ease tight market conditions.

Indian refiners, according to industry sources, are evaluating the feasibility of procuring these volumes. The technical barriers are minimal, given that Indian refineries have prior experience processing Iranian grades and can reintegrate them with limited adjustments. However, the real constraints lie elsewhere.

Payment mechanisms, insurance coverage, and shipping logistics remain critical uncertainties. The waiver does not fully resolve banking restrictions, which historically required complex arrangements such as local currency settlements and restricted accounts. Without clarity on these operational aspects, refiners are likely to proceed cautiously despite the commercial attractiveness of Iranian crude, which is typically offered at competitive pricing.

Parallel to this, India has already begun diversifying its crude sourcing in response to geopolitical risks. Imports of Venezuelan crude have resumed after a gap of nine months, with shipments expected to arrive through April. This indicates that Indian refiners are not reacting solely to immediate disruptions but are proactively building supply flexibility.

At the same time, Russian oil continues to dominate India’s import basket, with volumes rising sharply in March as refiners capitalised on discounted cargoes following earlier sanction relaxations. This underscores a broader trend: India’s crude procurement strategy is becoming increasingly opportunistic, driven by pricing and availability rather than long-term supplier alignment.

From a market perspective, the re-entry of Iranian oil if it materialises—could have multiple implications.

For India, access to discounted Iranian barrels could help offset elevated crude prices, which have surged amid the West Asia conflict. This would be particularly relevant for oil marketing companies and refiners facing margin pressures. Lower input costs could support refining spreads and partially cushion the impact of high global benchmarks.

At a sector level, the development reinforces the ongoing shift toward diversified sourcing. Indian refiners are no longer dependent on a single geography, instead leveraging geopolitical dislocations to optimise procurement.
