Crude Oil Prices Surge Amidst Ongoing Iran-US Tensions
Crude oil is hovering near $80 per barrel for the fourth consecutive session, extending a rally that has reversed roughly a third of this spring’s ceasefire-driven decline — and the market’s next move depends almost entirely on whether President Donald Trump turns a rhetorical threat into a military reality by seizing Kharg Island, the coral outcrop off Iran‘s Gulf coast that processes nearly nine of every ten barrels the Islamic Republic exports. With the fifth wave of U.S. airstrikes targeting Iranian missile sites along the Strait of Hormuz already underway, and the Section 122 import surcharge set to expire by operation of law on July 24 — eight days from now — importers and energy consumers face compounding pressure from two simultaneous policy crises that are rarely covered in the same breath.
The short answer to what changed this week: a ceasefire that never found solid legal footing has collapsed completely, a naval blockade has been reinstated, insurance costs have surged back to five percent of hull value, and the mechanism that was supposed to keep the June 17 memorandum of understanding alive — a safe-passage framework for commercial vessels — turned out to have a structural technical flaw that made its breakdown near-inevitable.
A Ceasefire Signed in Versailles, Undone by a Dark-Ship Problem
The June 17 MOU between Washington and Tehran was always built on contested ground. The accord called for a halt to military operations on all fronts and committed Iran to its “best efforts” for safe passage of commercial vessels through the Strait of Hormuz — with no transit fees for an initial 60-day period. Trump heralded it as Iran’s “unconditional surrender.” The ambiguity in that “best efforts” clause, over whether Iran retained authority over passage through the strait’s shipping lanes, was apparent from the first week.
But the deeper flaw was technical, not diplomatic. The Strait of Hormuz‘s shipping lanes run primarily through Omani territorial waters, governed by international maritime law and the United Nations Convention on the Law of the Sea (UNCLOS). For the MOU’s safe-passage guarantee to function in practice, someone needed to be able to distinguish protected commercial vessels from non-protected ones in real time. The system that does that is the Automatic Identification System — a VHF radio-based transponder that broadcasts a ship’s identity, position, course, and speed, mandatory under international maritime conventions for commercial vessels over 300 gross tons.
The conflict destroyed the conditions AIS depends on. As Iranian attacks on commercial vessels accelerated in late June and early July, operators began disabling their transponders — going “dark” — to reduce their targeting profile. Iran‘s Islamic Revolutionary Guard Corps then struck vessels that were transiting with their transponders turned off, as confirmed by U.S. Central Command. The MOU’s safe-passage clause could not be enforced for vessels it could not identify. The framework collapsed not because Iran stopped pretending to honor it, but because the conflict itself created the incentive structure that made the tracking protocol unworkable.
The Ceasefire Timeline: From Ankara to Blockade Reinstatement
The MOU began unraveling within days of being signed. Iran launched a drone strike against a ship in the strait just over a week after the June 17 signing — an act Washington interpreted as a ceasefire violation that prompted a contained round of retaliatory strikes. The two sides traded interpretations of the MOU’s Hormuz language: Iran insisted it retained some authority over passage; the U.S. argued the pact paved the way for an open waterway by the end of 60 days.
The final break came on July 8. At the NATO summit in Ankara, Trump declared the ceasefire “over,” called Iranian leaders “scum” and “sick people,” and authorized a second consecutive night of U.S. airstrikes. That same night, U.S. Central Command struck 90 targets inside
