Three Iranian oil tankers passed through a US naval blockade zone on June 17, carrying approximately 5 million barrels of crude oil. It’s the first time Iranian crude has moved through the area in two months, and it signals that the months-long Strait of Hormuz standoff may finally be winding down.
The tankers, identified as the Hero II, Diona, and Sonia I, made their transit after the US and Iran reached a memorandum of understanding aimed at reopening one of the world’s most critical shipping chokepoints. Brent crude prices dropped nearly 5% on the news, with analysts projecting prices could settle below $80 per barrel if traffic continues to flow without disruption.
How the Strait of Hormuz crisis unfolded
Iran began imposing restrictions on shipping through the Strait of Hormuz in late February 2026. By April, the US had responded with blockades on Iranian ports. For two months, Iranian crude exports were effectively frozen.
During the early phase of the crisis in April, Iran floated an unusual proposal. Tehran suggested implementing $1-per-barrel transit tolls for ships passing through the Strait, payable in Bitcoin. The proposal didn’t gain traction as a serious policy mechanism, but it did turn heads in both energy and crypto circles as a signal of how nation-states are beginning to think about digital assets in the context of sanctions and international commerce.
