Strait of Hormuz Reopens Amid U.S.–Iran Deal: Traffic, Prices, and Uncertainty
6/23/2026, 12:16:57 AM
Reopening of the Strait of Hormuz
Following a 14-point memorandum of understanding signed by U.S. President Donald Trump and Iranian President Masoud Peze shkian, commercial vessels were again permitted to transit the Strait of Hormuz. The agreement includes a 60-day toll-free period and a U.S. waiver of sanctions on Iranian oil, marking the first official reopening after the February 28 blockade.
Background and Context
The strait, a conduit for roughly 20 % of global petroleum liquids, was sealed off after U.S. and Israeli strikes on Iran in late February 2026. At the height of the closure, daily transits fell from 130 to single-digit levels, prompting the largest oil-market disruption in decades. The MoU aims to restore “free and open transit,” but regional tensions—particularly Israeli attacks in Lebanon—have prompted Iran’s Islamic Revolutionary Guard Corps (IRGC) to threaten renewed closures.
Traffic Data and Price Movements
- Ship counts: Kpler recorded 25 crossings on 18 June, 20 on Saturday, and 71 confirmed transits between 19-21 June (MarineTraffic).
- Route patterns: Most vessels used Iran-designated lanes; ? 50 % of ships operated with AIS off (“dark” routes).
- Oil prices: U.S. crude fell 2.7 % to $74 per barrel on Monday; Brent slipped 0.9 % to just under $80 after briefly rising on Friday.
- Volumes: U.S. Central Command reported 55 merchant ships moving > 17 million barrels on Saturday, while Kpler’s count for the same day was 20 ships.
Official Statements and Responses
U.S. Treasury Secretary Scott Bessent announced the sanctions waiver, emphasizing Iran’s pledge to keep the strait open. Vice President JD Vance said Iran was “honoring its end of the commitment.” Energy Secretary Chris Wright asserted that oil and gas flows have “already returned to normal” and will continue regardless of ongoing nuclear talks. CENTCOM spokesperson Capt. Tim Hawkins maintained that the strait remains open and U.S. forces are monitoring safe passage. Iran’s foreign ministry spokesman Esmaeil Baghaei noted that a “mechanism … was set up” to ensure safe commercial navigation.
Criticism and Opposition
Ship-owner groups, including INTERTANKO, warned that without clear protocols for mines, insurance, and tolls, operators remain hesitant. Insurance premiums have surged to 8 % of vessel value, and many carriers continue to route ships around the Cape of Good Hope. Analysts stress that “dark, sanctioned, Iranian-linked” traffic resembles the late-blockade baseline rather than a fully functional corridor.
On-the-Ground Shipping Reports
Kpler data show a mix of Saudi-flagged VLCCs, UAE-registered tankers, and Indian supertankers using the Omani-coast route, with several vessels re-activating AIS after periods of darkness. Windward’s monitoring indicated a sharp drop to 12 transits on Sunday, reflecting the impact of Iran’s renewed closure announcement. Bloomberg tracked Indian-owned tankers carrying ? 6 million barrels of Iraqi and Kuwaiti crude through the southern lane.
Conflicting Reports and Gaps
- Ship counts: CENTCOM’s 55 ships vs. Kpler’s 20 ships on the same day.
- Transit totals: MarineTraffic’s 71 crossings over three days contrast with Kpler’s 25 on 18 June.
- Mine clearance: Exact numbers and locations of naval mines remain undisclosed, hindering full confidence in the route.
Verbatim Quotes
- “committed to free and open transit in the Strait of Hormuz.” — Scott Bessent, U.S. Treasury Secretary
- “The current traffic profile: dark, sanctioned, Iranian-linked, resembling the late-blockade baseline more than a functioning open strait,” — Windward (via X)
- “The strait is open and the U.S. blockade against Iran has ceased.” — Capt. Tim Hawkins, U.S. Central Command
- “I'm long out of the business of predicting oil or gasoline prices, but they will continue to head down.” — Chris Wright, U.S. Secretary of Energy
- “Verified Strait of Hormuz crossings reached 25 on 18 June, marking a notable increase in daily maritime activity,” — Kpler (via X)
What’s Next
The 60-day toll-free window expires in late August, after which Iran may negotiate tolls with Oman and Gulf states. Mine-sweeping operations are expected to take months, and insurers are likely to keep premiums elevated until clearance is verified. Ongoing diplomatic talks in Switzerland aim to resolve nuclear issues and solidify a long-term framework for safe passage, but analysts caution that traffic will only gradually approach pre-war levels, with full normalization possibly taking six months or more.
