Iran Announces Closure of the Strait of Hormuz Amid Cease-fire Talks
On 20 June the Islamic Revolutionary Guard Corps declared the Strait of Hormuz closed, saying Israeli strikes in Lebanon and U.S. “bad faith” violated the 14-point cease-fire memorandum signed 17 June between President Donald Trump and Iranian President Masoud Peze shkian. The announcement came as technical talks were slated for Switzerland, and it directly challenged the interim agreement that required toll-free, open passage for at least 60 days.
Shipping Activity After the Interim Deal
U.S. Central Command reported that 55 merchant vessels carrying more than 17 million barrels of oil transited the strait on Saturday, while Kpler data showed 25 crossings on Thursday, the highest since mid-April. Pre-war traffic averaged about 130 ships per day; roughly 500 vessels and 20 000 crew remain anchored in the Gulf, and Intertanko estimates about 80 mines still block the central lane.
Official Statements
Capt. Tim Hawkins of U.S. Central Command said Iran does not control the strait and that traffic continues, adding U.S. forces are monitoring the passage. Vice President JD Vance echoed the assessment, noting no evidence of a closure and citing a record 16 million barrels moved in a day. Iran’s IRGC Navy warned ships “not to approach … otherwise your security will be jeopardized.” The Iranian foreign ministry said vessels must obtain permits from the Persian Gulf Strait Authority and that future insurance fees could be imposed.
Criticism & Opposition
Maritime insurers have not restored war-risk coverage, raising costs. Shipping groups such as Hapag-Lloyd argue any toll would breach international law, and operators cite safety, mine clearance and unclear transit rules as reasons to delay sailing.
Conflicting Reports & Gaps
Iran’s claim of a full closure conflicts with CENTCOM data showing 55 ships transiting and with satellite traffic counts. Iran’s permit requirement also clashes with U.S. statements that no arbitrary restrictions exist. The precise number of mines and the timeline for clearance remain unknown.
