India summons US diplomat over tanker strike in Gulf of Oman, three Indians reported missing

India called in a US diplomat to formally protest a military strike on an oil tanker in the Gulf of Oman, an incident that put 24 Indian seafarers in harm’s way and added another layer of friction to an already volatile geopolitical picture in the region.

The strike, carried out on June 8, targeted the Palau-flagged tanker MT Marivex after the vessel allegedly attempted to breach a US-enforced blockade aimed at Iranian ports. An F/A-18 Super Hornet launched from the USS Abraham Lincoln fired a precision munition at the ship’s engineering and steering areas. The tanker caught fire.

What happened in the Gulf of Oman

The MT Marivex was no stranger to controversy. The vessel had been previously sanctioned for its links to Iranian oil trade, and its attempted run through the blockade made it the seventh ship disabled under intensified US enforcement operations in the region.

After the strike ignited a fire onboard, the crew issued distress calls detailing both the attack and the blaze. Omani military helicopters carried out the rescue operation, pulling all 24 crew members to safety.

Indian authorities, including the Ministry of Ports, Shipping and Waterways, confirmed they were coordinating with Oman on the crew’s safety. The formal summoning of a US diplomat signals that New Delhi views this as more than a routine maritime enforcement action.

A pattern of escalation in the Gulf

This wasn’t an isolated event. The MT Marivex strike was the seventh vessel disabled under what has become a sustained US campaign to choke off Iranian oil exports through naval enforcement.

Prior US actions in May 2026 against vessels linked to Iran had already rattled energy markets. Oil prices spiked above $100 per barrel during that earlier round of confrontations.

Oman’s role as the rescue coordinator adds another dimension. The sultanate’s military conducted the rapid response to the distress calls following the June 8 strike.

What this means for energy and crypto markets

For investors watching energy-sensitive assets, including crypto, the Gulf situation deserves attention. Prior US enforcement actions in May 2026 caused oil to breach $100 per barrel, and the volatility bled into broader markets including major cryptocurrencies.

Seven disabled vessels and counting means this is not a one-off policy. It’s a campaign. Each new incident raises the probability of a miscalculation that could trigger a risk-off event affecting speculative assets.
