Strait of Hormuz Crisis: Indian Oil Tankers Transit Amid US-Iran Peace Talks

Three Indian-flagged crude oil tankers — Desh Vaibhav, Desh Vibhor, and Sanmar Herald — successfully crossed the Strait of Hormuz on 20 June 2026, carrying over 8.6 lakh metric tonnes of cargo and 94 Indian crew members. The vessels are now headed to Indian ports: Desh Vaibhav and Desh Vibhor are expected to arrive at Vadinar and Sikka ports respectively on 24 June, while Sanmar Herald is scheduled to reach Paradip Port on 1 July 2026. Union Minister for Ports, Shipping and Waterways Sarbananda Sonowal confirmed the successful transit, describing it as part of the government's priority efforts to protect India's maritime interests and energy supply chains.

The transit came against a backdrop of significant diplomatic activity surrounding the West Asia conflict. On 15 June 2026, the United States and Iran signed a Memorandum of Understanding (MoU) — referred to as the Islamabad MoU — calling for an immediate and permanent halt to military operations on all fronts, including Lebanon. This agreement, signed by US President Donald Trump and Iranian President Masoud Pezeshkian, also allowed Iran to sell oil freely in international markets and led to the lifting of the US maritime blockade on Iranian ports. As a result, the Strait of Hormuz — which had remained largely shut for months — began reopening to commercial shipping.

However, the situation remained volatile. On the same day as the Indian tankers' transit, Iran's military command announced it was reclosing the Strait of Hormuz, citing Israel's continued airstrikes in southern Lebanon as a violation of the MoU's ceasefire clause. Iran's Islamic Revolutionary Guard Corps (IRGC) warned all vessels to stay away from the strait. US Vice President J.D. Vance disputed Iran's claim, stating that 16 million barrels of oil had moved through the strait the previous day and that no closure was observed. Meanwhile, follow-up technical talks between the US and Iran, mediated by Pakistan and Qatar, were first postponed from 19 June and then rescheduled for 21 June at the Burgenstock resort in Switzerland. Pakistan's Prime Minister Shehbaz Sharif and army chief Field Marshal Syed Asim Munir were expected to participate in those discussions.

India's energy security has significant exposure to the West Asia situation. Before the conflict, roughly 90 percent of India's LPG imports came from Gulf suppliers. To reduce this dependence, India diversified its sourcing sharply — by April 2026, the United States supplied nearly one-third of India's LPG imports, up from just 8 percent in February 2026, aided by a 2.2 million tonne-per-year LPG supply deal signed with the US in late 2025. Iran also re-entered India's import basket at around 6 percent of April supplies, with additional imports sourced from Argentina, Chile, France, and the Netherlands. State-owned fuel retailers absorbed much of the rise in international prices to protect household consumers.

For exam aspirants, this story covers several important themes: the strategic importance of the Strait of Hormuz as a global oil chokepoint, India's energy import diversification strategy, the role of multilateral diplomacy (US, Iran, Pakistan, Qatar, Switzerland) in de-escalation, and how regional conflicts directly affect India's import costs and energy security. The MoU framework and India's policy response are relevant to both international relations and economy sections of competitive exam syllabi.
