Key TakeawaysPakistani mediators expect Iran to submit a revised peace proposal as early as Tuesday or by Friday at the latest, per CNN cited by BlockBeatsThe delay is attributed to difficulties in reaching Iran's Supreme Leader, Ayatollah Mojtaba Khamenei, whose sign-off appears necessary for any formal responseTrump previously rejected an earlier version of Iran's peace offer, requiring Tehran to revise its proposalPakistani Prime Minister Sharif publicly stated that Iran's Foreign Minister personally assured him of a reply, adding diplomatic pressure on TehranThe White House has signaled its patience is wearing thin, raising the stakes for Iran's response windowPakistani mediators expect Iran to submit a revised peace proposal to the United States either later Tuesday or by Friday at the latest, CNN reported on April 29, as diplomatic efforts to end the US-Iran conflict enter a critical window with multiple parties signaling diminishing patience.The revised proposal is required after President Trump rejected an earlier version of Iran's peace offer. Sources familiar with the matter told CNN that Iran could respond as early as Tuesday, though delays have pushed the realistic window toward Friday -- with the uncertainty itself reflecting the difficulties negotiators are encountering in securing a formal response from Tehran.Khamenei Access Is the Core BottleneckSources indicated that the primary source of delay is difficulty in contacting Iran's Supreme Leader, Ayatollah Mojtaba Khamenei, whose approval appears to be a prerequisite for any official Iranian position on revised peace terms. The inability to secure direct access to the ultimate decision-maker within Iran's fractured power structure has been a recurring obstacle throughout the negotiation process, with hardline IRGC factions also complicating the civilian government's ability to speak with a unified voice.Pakistan Applies Public PressurePakistani Prime Minister Shehbaz Sharif added a layer of public diplomatic pressure by telling his cabinet that Iran's Foreign Minister -- who led negotiations in Islamabad over the weekend -- personally assured him that a reply would be forthcoming. No specific timetable was attached to that assurance, but Sharif's decision to make the commitment public is a notable escalation of diplomatic pressure on Tehran.White House Patience Running ThinThe compressed timeline is further tightened by signals from Washington. The White House has indicated its patience is wearing thin, framing the Friday window as a de facto deadline rather than a flexible target. The combination of a truncated ceasefire extension, Khamenei access difficulties, and a visibly impatient White House makes the next 48–72 hours one of the most consequential diplomatic windows of the conflict.Crypto and Market ImplicationsFor financial markets including crypto, the Iran proposal timeline is a binary near-term catalyst. A revised proposal that gains White House approval could ease the geopolitical risk premium embedded in oil prices -- with Brent currently above $114 per barrel -- and provide a meaningful tailwind for Bitcoin and risk assets. A failure to submit or a second rejection would likely extend the energy price spike and keep macro conditions hostile for risk-on positioning heading into the May monthly open.
