A ceasefire exists. Whether it means the same thing to the parties who signed it is another matter entirely.
Trump announced a two-week pause two hours before his deadline expired. Iran's SNSC released a ten-point framework. Israel continued striking Lebanon. The IRGC hit Lavan Island after the deal was announced. Only two ships transited Hormuz. Oil sits at $94/bbl as if nothing happened, which tells you markets are pricing in the best case.
They shouldn't be.
The table below reflects the post-ceasefire landscape — not the pre-ceasefire escalation calculus that dominated last week's numbers, but the specific fragilities of a deal where neither side agrees on what was agreed. Some probabilities have dropped sharply (civilian infrastructure campaign, full Hormuz closure). Others have risen (Israel breaking the deal, IRGC testing boundaries). The structural risk hasn't disappeared; it has migrated.
Event | Probability |
|---|---|
Ceasefire holds 48 hours | 65–75% |
Ceasefire holds 2 weeks (through Islamabad) |
45–55% |
Ceasefire holds 30 days | 30–40% |
IRGC violates ceasefire directly | 40–50% |
Israel violates ceasefire via Lebanon | 50–60% |
Lavan-type post-ceasefire strikes recur | 30–40% |
The 48-hour number looks robust because both sides have immediate incentives to appear compliant — Trump needs the win, Mojtaba needs to demonstrate authority. But the Israel carve-out is the tell. The largest coordinated strike in Lebanon since the war began happened the same day the deal was announced. That's not a violation in Washington's reading; it's the explicit terms. In Tehran's reading, every Israeli strike on Hezbollah is a red line crossed. These are incompatible interpretations coexisting under the same document.
The IRGC violation probability is high not because the Guard wants to sabotage the deal — though some factions do — but because Mojtaba's authority to enforce compliance is untested and likely insufficient. The IRGC assumed operational control during the transition. The ceasefire was Mojtaba's first major act. If Guard commanders on the coast decide to continue minelaying or harassment, there is no credible chain of command to stop them.
Event | Probability |
|---|---|
Hormuz functional reopening (20+ ships/day) within 2 weeks | 25–35% |
Hormuz remains throttled (under 5 ships/day) for 2+ weeks | 55–65% |
Full closure reimposed | 15–22% |
The technical opening is a fiction. Two ships transiting when normal traffic is 20 million barrels per day isn't an open strait — it's a token. Mines remain uncleared. The IRGC Navy, which controls coastal operations, has no incentive to expedite clearance. Iran and Oman have announced they will charge vessels for passage, which adds a friction layer that keeps transit below pre-war volumes even if clearance accelerates.
The most likely scenario is sustained throttling: enough traffic to prevent the humanitarian catastrophe that would force external intervention, but not enough to restore market equilibrium. This is the grey zone that serves IRGC interests — leverage without the escalation of full closure.
Event | Probability |
|---|---|
Islamabad talks produce extension only | 45–55% |
Islamabad talks produce substantive agreement | 15–25% |
Islamabad talks collapse | 25–35% |
Pope Leo XIV mediation success (30-day) | 25–35% |
The Islamabad track is the most promising diplomatic pathway and the most likely to disappoint. Pakistan's mediation credibility was already strained by the Jubail strike — Riyadh is a key Saudi partner, and the IRGC attack on Saudi infrastructure makes Islamabad's neutral posture harder to sustain. The structural gaps between Iran's ten-point framework (sanctions lifting, Hormuz control guarantees) and US demands (verified nuclear rollback, no preconditions) haven't narrowed. The most probable outcome is a further extension — another two weeks of pause while neither side concedes on substance.
Pope Leo XIV's channel remains live but secondary. Its value increases if Islamabad stalls, providing an alternative venue for confidence-building measures. But the Vatican has no enforcement mechanism and no leverage over the IRGC.
Event | Probability |
|---|---|
Mojtaba retains authority over IRGC at 30 days | 35–45% |
IRGC effectively autonomous by Day 30 | 55–65% |
Mojtaba hospitalized/incapacitated (unconfirmed wound) | 20–30% |
This is the analytical thread that isn't getting sufficient attention. Mojtaba lacks the clerical credentials, institutional relationships, and moral authority his father accumulated over three decades. Unconfirmed reports place him in a Qom hospital following the strike that killed Khamenei — if true, the IRGC's assumption of operational control during the transition may become permanent by default. The ceasefire order is only as durable as the Guard allows. If Mojtaba cannot project authority, the "Iran" that agreed to the ceasefire and the "Iran" that controls coastal operations are functionally different actors.
Event | Probability |
|---|---|
Saudi retaliation for Jubail within 2 weeks | 35–45% |
Saudi retaliation deferred beyond 30 days | 40–50% |
Gulf states enter collective security arrangement with US | 45–55% |
The Jubail strike was the IRGC's signal that the Saudi front remains active regardless of the ceasefire's terms. Riyadh has deferred retaliation but not resolved the question. The King Fahd Causeway closure as a precaution tells you the Saudi threat assessment hasn't downgraded. Pakistan's mediation becomes nearly untenable if Riyadh strikes back — Islamabad cannot broker talks between two parties while a third is under attack by one of them.
Event | Probability |
|---|---|
AUMF passed (Congress) | 55–65% |
AUMF vote delayed past Islamabad talks | 35–45% |
Oil sustained above $150/bbl | 15–22% |
US ground operations | 5–10% |
The ceasefire paradoxically strengthened AUMF skeptics. Trump's "destroy civilization" rhetoric followed by a two-week extension gives Jeffries and Pelosi a concrete data point: the administration escalated to the brink, then pulled back, suggesting the original escalation exceeded both strategic necessity and constitutional authority. The "war of choice" framing now has evidentiary support. Passage probability drops if Islamabad produces meaningful progress; it rises if the ceasefire collapses.
Oil at $94/bbl embeds best-case assumptions about Hormuz reopening that the traffic data doesn't support. The market is pricing in a return to normal that requires both sustained ceasefire compliance and IRGC cooperation on mine clearance — neither of which is assured.
Outcome | April 7 (Pre-Ceasefire) | April 8 (Post-Ceasefire) | Direction |
|---|---|---|---|
Ceasefire within 48 hours | 35–45% | Happened | — |
Ceasefire within 2 weeks | 55–65% | Holds at 45–55% | ↓ |
Hormuz full closure (14-day) | 35–45% | 15–22% | ↓↓ |
Israel undermines ceasefire | 40–50% | 50–60% | ↑ |
Wider civilian infrastructure campaign | 25–35% | 15–22% | ↓↓ |
AUMF passed | 60–70% | 55–65% | ↓ |
Maritime naval incident | 30–40% | 25–35% | ↓ |
Oil above $150/bbl | 20–28% | 15–22% | ↓ |
The ceasefire removed the worst-case tails but created a new center of risk: a deal that neither side reads the same way, enforced by a leader who may not control his own military, with a strait that's technically open and functionally closed. The probabilities moved toward the middle. The distribution compressed. That's not the same as the distribution improving.
The next 48 hours are the stress test. Watch Hormuz traffic volume. Watch IRGC coastal activity. Watch whether the Lavan strike was an outlier or a pattern. Watch whether Israel's Lebanon campaign escalates to the point where Tehran cannot maintain the fiction of separate fronts. The ceasefire is real. The peace is not.

Revised probabilities after the two-week ceasefire — the worst-case tails dropped, but a new center of risk emerged: incompatible readings, untested authority, and a strait that's technically open and functionally closed.
