Daily Strike — Morning Edition

In the twelve hours since Thursday evening’s brief, the US-Iran file has produced its sharpest contradiction of the cycle. The Islamic Revolutionary Guard Corps opened fire on commercial shipping in the Strait of Hormuz on Friday morning, and within hours Vice President JD Vance told reporters that Washington and Tehran are “very close” to a memorandum of understanding. Both tracks — kinetic and diplomatic — are now running at the same time, and neither side has signed the 60-day truce extension that mediators put on the table earlier in the week.

Hormuz: kinetic and diplomatic tracks now running simultaneously

The IRGC’s Friday morning action against shipping in the Strait of Hormuz was reported across regional outlets and is being treated by Western capitals as a deliberate signaling shot rather than a campaign opener. Within the same news cycle, Vice President Vance characterized the state of negotiations as “very close” to a memorandum of understanding, language that goes further than any administration figure has used to date. Tehran has not yet responded to the proposed 60-day truce extension, and President Trump has yet to comment publicly on the framework.

Sanctions cadence continues

The State Department on Friday announced new designations targeting entities and individuals it says are involved in transporting Iranian crude. The action follows Thursday’s Treasury OFAC measure against the Persian Gulf and Strait Authority and continues the administration’s pattern of pairing negotiation overtures with steady sanctions output. Officials briefing reporters described the two tracks as deliberate: the pressure track and the talks track are designed to run in parallel, not to displace one another.

Markets

Energy executives quoted by Middle East Eye warned that Brent could “shoot up” toward $150 a barrel if Hormuz disruptions resume at scale. To date the price has not moved that way. Brent has held in the mid-$70s through the cycle, supported by record US crude exports and continued Strategic Petroleum Reserve releases — the dynamic detailed in /articles/2026-05-29-us-crude-exports-record-spr-releases-hormuz-bets-cool-brent/. On the procedural side, OFAC again extended the deadline for the sale of Lukoil’s global assets, now June 27, a rolling administrative extension rather than a policy shift. Separately, China’s factory-gate export prices rose as higher oil costs passed through industrial inputs. Session-end levels not in this brief.

Secondary fronts

Prime Minister Netanyahu directed the Israel Defense Forces to expand operational control to approximately 70 percent of the Gaza Strip, a step that widens the parallel regional theater while US-Iran talks proceed. Separately, US Central Command publicly denied Iranian state media claims that a US aircraft had been brought down. It is the third such denial CENTCOM has issued in the past two weeks.

What to watch tomorrow

1. Whether Tehran issues a formal response to the proposed 60-day truce extension or allows Vice President Vance’s “very close” characterization to stand uncontested.
2. Whether the IRGC repeats Friday’s Hormuz firing or treats it as a one-off signaling shot calibrated to the talks.
3. Whether OFAC publishes the new Iran-oil designations list and which named persons and vessels appear on it.

What we’re tracking but haven’t published on yet

• Gulf shipping war-risk insurance premia for Hormuz transits. No published rate updates landed in this window; underwriters are quoting privately.
• Russian and Chinese statements on the proposed US-Iran MoU framework. Neither capital has issued a formal position since Vance’s remarks.
• Lebanon front: mass evacuations are reported underway in southern Lebanon as Israeli strikes expand toward Tyre and Nabatieh. We will publish a standalone article if the scope warrants it.
