Key Movements
Two Chinese VLCCs—Yuan Gui Yang (2 m bbl Iraqi Basrah) and Ocean Lily (1 m bbl each Qatari al-Shaheen and Iraqi Basrah)—and South Korean VLCC Universal Winner (2 m bbl Kuwaiti) exited the Strait of Hormuz on 20 May after a >2-month wait. LSEG, Kpler and MarineTraffic data show arrivals at Shuidong, Quanzhou and Ulsan in early June.
Background & Context
The strait, moving ~20 % of world oil/LNG, was sealed after U.S.–Israeli strikes on Iran on 28 Feb 2026. Iran created a “Persian Gulf Strait Authority” and a controlled zone, but a cease-fire on 8 Apr permitted limited “strait management protocols” for East Asian vessels. European states are negotiating case-by-case access.
Data & Statistics
- Cargo exiting 20 May: 6 m bbl (4 m bbl Chinese, 2 m bbl South Korean).
- Pre-conflict flow ? 20 m bbl/day; current ? 4-5 vessels/week.
- U.S. SPR drawdown: 9.9 m bbl (record).
- U.S. commercial crude inventories down 7.9 m bbl to 445 m bbl.
Why It Matters
The shipment eases part of the gap that lifted Brent above $110 bbl in early May, showing coordinated transits can occur despite diplomatic tension. Analysts warn Iran’s fee-based “strait management” and inventory drawdowns may keep volatility high.
Official Statements & Responses
- President Donald Trump: war could end “very quickly” if Tehran agrees.
- Vice President JD Vance: “we’re in a pretty good spot.”
- Iran’s parliamentary security chief Ebrahim Azizi: Trump’s pause avoids a decisive Iranian response.
- Iran announced a new “Persian Gulf Strait Authority” to manage traffic and collect tolls.
- South Korean FM Cho Hyun: Universal Winner’s passage was coordinated with Iran and the United States.
- Unipec and Sinochem declined comment.
Criticism & Opposition
Iran’s Revolutionary Guard Navy warned vessels not complying with the new approval system could be turned back or face fees, calling it “the new norm.” The U.S. Joint Maritime Information Center still rates the area “high risk” after recent drone alerts. Wood Mackenzie forecasts Brent could hit $200 bbl if the strait stays largely closed.
Conflicting Reports & Gaps
Reuters reports 4 m bbl for Chinese tankers; Oilprice.com and TS2.Tech cite 6 m bbl across three vessels. Some sources list only two Chinese ships, others include the South Korean tanker. Loading dates differ between late February and early March.
Verbatim Quotes
- “We're in a pretty good spot here,” — JD Vance, U.S. Vice President
- “Investors are keen to gauge whether Washington and Tehran can actually find common ground and reach a peace agreement, with the US stance shifting daily,” — Toshitaka Tazawa, Fujitomi Securities analyst

What’s Next
Iran says it will soon publish a “professional mechanism” for traffic management. U.S. and Iranian officials continue daily diplomatic contacts. Market watchers expect more case-by-case transits, but any renewed strike could halt progress and push Brent toward $120 bbl.
