Iran's Blockade Is All But Over
At 93%, the money has reached a verdict — the US will announce an end to Iran's blockade well before the calendar runs out on 2026.
Based on: Iran's Blockade of the Strait Is Virtually Certain to End This Year
The market has spoken with something close to finality: there is a 93% probability that the United States announces the end of Iran's blockade of the Strait of Hormuz before December 31, 2026. That is not a lean or a tilt — that is virtual certainty, the kind of consensus that forms only when informed money has settled its doubts and moved on. The question at this point is not whether the blockade ends, but when.
The pricing across the Hormuz cluster tells a coherent and mutually reinforcing story. A US-Iran effective ceasefire already trades at 76%. The Israel-Iran ceasefire is priced at 100% through August 2. WTI crude oil is all but certain to hold above $72 through early August, and the probability of a catastrophic $115 oil spike by year-end has actually slipped to 33% — the market is not pricing a prolonged siege. Meanwhile, the near-term 'Strait traffic back to normal by August 31' contract sits at only 16%, which means the money expects the formal diplomatic announcement to precede the physical restoration of full shipping flows — a sequencing entirely consistent with how these crises historically resolve. The 'normal traffic by December 31' contract at 60% confirms that the end of the blockade and the normalization of commerce are expected to arrive on separate timelines, with the announcement coming first.
Why is the consensus almost certainly right? The ceasefire architecture is already in place. With an Israel-Iran ceasefire locked in at 100% and a broader US-Iran ceasefire at 76%, the political scaffolding needed for a formal blockade-end announcement is effectively built. Governments — particularly the United States — do not sustain costly naval postures and diplomatic crises once the underlying armed conflict has cooled. The people holding this conviction at 93% are most plausibly those with visibility into back-channel diplomacy, the kind of traders who front-run announcements rather than react to them. The crude oil market is corroborating: the 84% chance of WTI touching $75 in August implies a modest relief rally, not the extended premium you would expect if serious blockade risk remained on the table.
The scenario that breaks this argument is narrower than the 7% tail suggests but not trivial. A collapse of the ceasefire — perhaps triggered by a rogue strike, a domestic political rupture in Tehran, or an Israeli escalation that pulls Washington back in — could freeze any announcement indefinitely. The Kharg Island contract at 10% and the Iran full airspace closure contract at 37% are the market's own acknowledgment that harder outcomes remain alive. If the ceasefire frays before a formal announcement is made, the 93% consensus unravels quickly. Seven percent is small; it is not zero.
This argument is the market's, decoded — not investment advice.
