HORMUZ DEAL BRINGS FIRST TANKERS BUT NOT THE FLOOD
Three saudi supertankers carrying 6 million barrels have crossed the strait after a us-iran deal, but data shows the real surge hasn't started yet.

Three supertankers from Saudi Arabia loaded with 6 million barrels of oil have crossed the Strait of Hormuz for the first time since the U.S. blockade of Iran ended. The ships Shaden, Awtad, and Jaham ran dark for more than two months, hiding their location in the Gulf of Oman. On Thursday, they switched their transponders back on and sailed through.
The crossings came a day after President Donald Trump and Iranian President Masoud Pezeshkian signed a deal meant to reopen the waterway. Vice President JD Vance told reporters later Thursday that "tankers carrying more than 12 million barrels crossed the strait overnight" and called it "That is a high since the beginning of the conflict". The U.S. Navy officially ended the blockade, and U.S. Central Command confirmed the lifting of restrictions.
Oil prices responded quickly. Brent crude fell to $78.11 a barrel as traders priced in renewed supply from the Persian Gulf. The prewar flow through Hormuz was 14 million barrels per day of crude oil plus 6 million barrels per day of refined products. Even a fraction of that return would pull prices lower. That is exactly what the market is anticipating.
VP NUMBERS VS ACTUAL DATA
Vance's 12 million barrels overnight is a big number, but it is not the same as a flood of shipping. The data firm Kpler, which tracks tanker movements, had not observed a major traffic increase as of Thursday morning. Analyst Matt Smith put it plainly: "The floodgates haven't opened, there is no mass exodus as yet".
The gap between the White House's framing and the on-the-water reality is worth watching. Before the Iran war, more than 100 ships transited the strait daily, dozens of them tankers. That normal flow has not returned. What returned is a few cautious moves by state-owned tankers and a handful of Saudi vessels that have been waiting weeks for the right signal.
THE STUCK FLEET AND THE CONFIDENCE PROBLEM
Kpler estimates that 118 tankers remain stuck in the Persian Gulf, unable to exit because of the blockade and the risk of mines and Revolutionary Guard patrols. That fleet could clear the strait within 15 days if shipping companies feel confident enough in the Iran deal. But confidence does not come from a piece of paper. It comes from watching other ships make it through without being hit.
The Joint Maritime Information Centre this week downgraded its threat assessment for Hormuz from severe to substantial. That is an improvement, but JMIC still cautioned that attacks in the strait are a "strong possibility" and mines in the sea lane remain a threat. It noted that the behaviour of Iran's Revolutionary Guard "has become less volatile" since the deal was announced. Less volatile is not the same as safe.
A dozen tankers per day might enter the Gulf to fetch oil within 30 days of the deal, according to Kpler's forecast. That is still well below prewar levels. The flow will ramp slowly as insurers, shipowners, and charterers rebuild their risk models.
THE IRANIAN SIDE
At least five Iranian ships have crossed the U.S. blockade line since June 16. Three of those were state-owned oil tankers that exited the Gulf of Oman. That shows Iran is also testing the reopening, but cautiously. The fact that Iranian state tankers went first suggests private operators are waiting for more evidence that the deal holds.
The three Saudi tankers are very large crude carriers, or VLCCs, each capable of carrying about 2 million barrels. The Shaden is headed to Kiire, Japan, and the Awtad is en route to Ulsan, South Korea. Jaham's destination is not yet clear. These are real deliveries, not positioning moves. They represent the first tangible step in restoring the world's most important oil chokepoint.
WHAT THE OIL MARKETS ARE SAYING
The drop in Brent crude to $78.11 is the market's vote of confidence that supply will increase. But the market has been wrong before. If the shipping data does not show a sustained rise in transits over the next two weeks, the price could bounce back. For now, the situation is best described by Matt Smith's observation: the floodgates haven't opened, and there is no mass exodus as yet. The policy machinery has unlocked the door, but the shipping industry is still deciding whether to walk through.
TWO SIGNALS TO LOOK FOR
First, whether the count of transits from Kpler shows a clear upward trend. Second, whether any new incidents occur in the Strait. The Revolutionary Guard has been less volatile, but mines do not know a deal has been signed. They drift and wait. The Joint Maritime Information Centre still rates mines as a threat.
The deal between Trump and Pezeshkian is a political breakthrough. Turning it into a logistical and commercial one will take longer.
