The Hormuz Blockade Ends This Year — Just Don't Hold Your Breath
At 79%, the case for a US-announced end to the Iranian blockade by December 31 is strong — but the near-term paths have all but collapsed.
Based on: The Hormuz Blockade Likely Ends This Year, but Not Soon
The Iranian blockade of the Strait of Hormuz is likely finished by the end of 2026. Not because diplomacy is thriving, not because Tehran is moderating, but because the weight of economic, military, and geopolitical pressure makes a prolonged closure increasingly untenable for all parties. The 79% probability on a US-announced resolution by December 31 reflects a broad and well-funded conviction that this standoff has a defined expiration date — even if the exact moment of release remains genuinely uncertain.
What the odds reveal most sharply is not just that resolution comes, but that it comes late. Every near-term contract has cratered. The September 30 outcome sits at 44% after shedding ground sharply in the past day, and August timelines are priced in the teens and single digits. Strait of Hormuz traffic returning to normal by September 30 is at just 14%. The 60-day negotiation extension contract is only at 24%, and a qualifying US-Iran diplomatic meeting by September 30 is now at 36% — down seven points in a single session. The picture that emerges is a resolution arc that bends toward year-end, not summer. The blockade ends, but it extracts maximum cost first.
Why does the consensus hold at 79% for December 31 even as earlier windows close? Because the underlying pressure never relents. Global Hormuz transit at normal levels by year-end sits at 46% — a coin flip that implies meaningful uncertainty about the pace of normalization even after a deal. Iran's supreme leadership structure appears stable, with Mojtaba Khamenei's hold on power priced at 82%, which paradoxically supports a negotiated off-ramp: a regime confident in its survival can accept terms without appearing to collapse. The actors with the most capital committed to these markets appear to believe that Washington and Tehran will eventually find a face-saving formula — and that the window for doing so is the back half of 2026.
What breaks this? A genuine diplomatic rupture — an escalation that forecloses negotiation rather than delays it. If the US-Iran diplomatic meeting fails to materialize even by September 30, the 65% probability already assigned to that outcome suggests the door is narrowing. A military incident in the strait, an Iranian airspace closure that is now priced at 32% and rising, or a leadership convulsion in Tehran could transform a delayed resolution into no resolution at all within the 2026 calendar year. The 21% chance priced against the December 31 contract is not trivial — it is the market's honest acknowledgment that wars and blockades do not always end on schedule.
This argument is the market's, decoded — not investment advice.
