At least three Iranian tankers, including two supertankers named Diona and Hero 2, have successfully navigated through the U.S. Navy blockade, carrying nearly five million barrels of crude oil.

This is the first such shipment in two months, occurring just ahead of a formal signing of a U.S.-Iran Memorandum of Understanding aimed at ending hostilities and potentially lifting sanctions on Iranian oil sales. Analysts suggest that this development indicates a cautious optimism among shipowners, with some repositioning vessels towards Gulf ports in anticipation of increased demand.

However, the maritime sector remains skeptical, with high war-risk insurance premiums still in place and many shipowners waiting for more concrete assurances regarding safety and the stability of the Strait of Hormuz. The U.S.

Navy has reiterated that the blockade remains until the agreement is officially signed, and while a significant backlog of tankers is expected to clear post-agreement, the overall recovery of traffic through the strait may be limited.

The situation underscores the fragility of the current maritime environment and the cautious approach of the shipping industry as it navigates these geopolitical developments
