But Trump has not signed off, Iran's semi-official channels are denying the deal is finalised, and the two sides spent yesterday trading fire near Bandar Abbas and at a US base in Kuwait. Pakistan's foreign minister is flying to Washington today to meet Rubio. The deal exists on paper. Whether it survives contact with the principals is still genuinely open. ## Lead story: THE FRAMEWORK IS REAL, THE SIGNATURES ARE NOT Here is the state of play as of Day 90. US and Iranian negotiators have agreed on a framework memorandum of understanding that would extend the ceasefire for 60 days and open formal talks on Iran's nuclear programme [1][2]. Axios broke the story Thursday, the White House confirmed it to Al Jazeera, and the BBC ran parallel sourcing from US officials [1][2]. That is not a leak or a rumour. Something was agreed at the working level. But Trump has not signed it. And Iran is not saying it has either. Tasnim, Iran's semi-official news agency, quoted a source close to the negotiations explicitly stating that no Western narrative about finalisation is valid until Iran announces it to the Pakistani mediator and to its own people [2]. That is a carefully worded denial. It does not say the text is wrong. It says the process is not complete, and Tehran will not let Washington define the moment of conclusion. The framework, as best as can be reconstructed across sources, includes: unrestricted vessel traffic through the Strait of Hormuz, a US lift of its naval blockade on Iranian ports, and the opening of nuclear negotiations covering Iran's highly enriched uranium stockpile, a time-limited enrichment suspension, and International Atomic Energy Agency (IAEA) supervision [6]. Iran would renounce nuclear weapons. The 30-day horizon for commercial shipping restoration is referenced in the Guardian's sourcing [6]. What the framework does not resolve clearly: sanctions relief, which Trump has repeatedly said is off the table; the precise governance of Hormuz passage, which remains the central friction point; and the fate of Iran's enriched uranium stockpile, which is explicitly deferred to the 60-day negotiating window rather than settled upfront [1][6]. China is pressing for any agreement to be ratified by the UN Security Council, which is a significant ask and one that would give Beijing formal standing in whatever comes next [6]. The deal's reception in Israel will be uncomfortable. It defers hard nuclear commitments, it requires a permanent ceasefire to include Lebanon, and it is less specific than Tehran's version on sanctions relief [6]. Netanyahu has been given the draft for comment, which means he has input but not a veto. What he does with that input in the next 48 hours is one of the most important variables in play. The thing most people are missing in the coverage: the timing of yesterday's exchange of fire matters enormously. Iran shot at four ships attempting to transit Hormuz without authorisation, the US struck a drone control station at Bandar Abbas in response, and Iran then targeted what appears to be a US base in Kuwait, with Kuwait deploying air defences against what it called "hostile" threats [11]. All of this happened while both sides' negotiators were reportedly finalising the framework text. The two sides are simultaneously agreeing to stop fighting and conducting the most serious military exchange since the ceasefire began. That is not a contradiction for either government. It is leverage management. But it is also the kind of thing that can spiral past the point where either side can control it. ## ALSO NOTABLE - **The US Treasury sanctioned Iran's Persian Gulf Strait Authority (PGSA), the body managing Hormuz passage fees, calling its toll collection "extortion" and threatening secondary sanctions on any firm or financial institution that complies with its requirements** [3]. This happened on the same day a ceasefire extension framework was reportedly agreed. Sanctioning the entity you are simultaneously negotiating to legitimise is either a maximum-pressure tactic designed to improve the final terms, or evidence that different parts of the US government are not fully coordinated. Either way, it signals the Hormuz governance question is not settled. - **Treasury Secretary Scott Bessent also threatened Oman with sanctions if it facilitates Iranian tolling of the strait, a day after Trump threatened to "blow up" Oman if it reached a side deal with Tehran on Hormuz management** [4]. Oman has not publicly sought control over the waterway. Threatening a close security partner this explicitly, for something it has not done, is genuinely unusual behaviour and reflects how much Washington fears a bilateral Iran-Oman arrangement that cuts the US out of Hormuz governance. The Oman relationship is quietly becoming one of the most stressed bilateral dynamics in the region. - **Satellite imagery, cited by CNN and reported by Israel Hayom, shows Iran has cleared debris from at least 50 access points across 18 missile sites since the ceasefire began** [12]. US intelligence sources confirmed to CNN that Iran is recovering "far faster than initial assessments," with four sources saying Iran has "beaten every timetable the intelligence community had." Full drone strike capability could be restored within six months [12]. Meanwhile, a Center for Strategic and International Studies (CSIS) report confirmed the US used over 1,000 Tomahawk cruise missiles against Iran and roughly 1,000 Patriot interceptors, and that replacing those stockpiles will take three to five years at current production rates [10]. The strategic implication of those two facts together is uncomfortable: Iran is rebuilding faster than the US is resupplying. - **Iran's internet has partially returned after 88 days of near-total blackout, and the reaction inside Iran is not celebratory** [13]. Iranians who spoke to the Guardian described mobile internet still down, WhatsApp barely functional, and VPN access marginally easier. Many viewed the partial restoration as a surveillance tool rather than a concession. One protester who had been arrested in January said: "This is not a sign of freedom" [13]. The regime is giving people just enough connectivity to reduce domestic pressure without restoring the tools that enabled protest coordination. ## MARKETS & MONEY The signal worth reading today is the gap between oil and volatility. Brent nudged up slightly to $93.05 from $92.50 yesterday, which is essentially flat, but the Oil Volatility Index (OVX) dropped again to 58.51 from 60.15, its lowest point in the data series here. Markets are pricing deal completion with more confidence than the diplomatic evidence supports. The Gold/Oil ratio has ticked up again to 50.77, maintaining its elevated position, which is the hedge trade staying in place even as energy traders relax. Gold itself is at $4,532, recovering from yesterday's dip. The Frontline tanker stock at $34.60 is worth watching: it has fallen from $39 a week ago, meaning shipping operators think Hormuz reopening is priced into oil but actual cargo flow restoration remains distant. Defence stocks are grinding steadily higher across the board. VIX at 15.68 is the calmest reading in the series. Equity markets are not afraid. Whether that is wisdom or complacency depends on what happens in Washington in the next 48 hours. ## WESTERN IMPACTS The threat of secondary sanctions on Oman is landing awkwardly in European capitals. European maritime operators have been quietly negotiating directly with Tehran's navy for passage through Hormuz [3], and the PGSA sanctions mean any European company that has paid or is considering paying Iranian passage fees is now exposed to US Treasury enforcement. That is a practical problem for shipping firms, insurers, and the governments that depend on them. The 20 percent of global oil and liquefied natural gas (LNG) that normally flows through the strait affects European energy prices directly, and three tankers were reported transiting with transponders off this week, heading toward India and China [3]. That shadow fleet activity is moving supply eastward, not westward, which is the structural story European energy ministries should be watching. ## WHAT TO WATCH 1. **Pakistan Foreign Minister Mohammad Ishaq Dar's meeting with Rubio in Washington today** [6]. Dar is the key mediating channel between Washington and Tehran, and this meeting was called specifically to accelerate the deal. If anything formal comes out of it, whether a joint statement, a named deadline, or a public endorsement of the framework text, the deal is moving. If Dar flies home without an announcement, the 60-day framework is still floating unsigned and vulnerable to the next exchange of fire. 2. **Whether Trump formally signs off on the memorandum of understanding in the next 24 to 48 hours, and specifically what the public text says about Hormuz governance and sanctions.** Bessent told reporters Thursday that there can be "no agreement that does not meet Trump's red lines" on Hormuz, enriched uranium, and the nuclear programme [2]. Iran's version of those same terms is materially different. Watch whether a signed text is described by Tehran's state media as a "framework for negotiation" or a "victory." The framing each side uses domestically will tell you more about what was actually agreed than any official statement. 3. **Iran's missile and drone rebuilding pace, and whether the CSIS munitions depletion report triggers any US congressional response.** The finding that the US needs three to five years to replenish Tomahawk, Patriot, and Terminal High Altitude Area Defense (THAAD) stocks [10] is already circulating in defence policy circles, and it directly undermines Trump's "finish the job" threat as a credible near-term option. If senators cite the CSIS report in hearings or floor statements this week, it reframes the negotiating dynamic: the US is not choosing between a deal and a resumed war. It is choosing between a deal and a war it is currently poorly positioned to fight. ## References 1. [BBC] BBC News: US and Iran reach tentative deal to extend ceasefire, US sources say 2.
