A Hormuz Deal Is Unlikely, but the Blockade May Not Last Forever

The Strait of Hormuz standoff is settling into an uneasy stalemate. Both the U.S.-Iran and Israel-Iran ceasefires are holding with near-certainty through mid-October, and transit call volumes through the strait remain active in the short term — yet the prospect of a formal diplomatic agreement, let alone a full restoration of normal shipping, looks remote by any near-term measure.

The money that has tracked this standoff closely is telling a layered story. A comprehensive Hormuz agreement before the 2026 midterms is unlikely — the odds sit firmly in that direction — and the path to normalized traffic by December 31 looks even harder, with the market putting only a 14% chance on that outcome and actually moving lower in recent days. What is shifting, modestly but meaningfully, is the possibility of a narrower Oman-brokered arrangement: that contract has climbed to 40% in recent days on notable volume, suggesting informed observers see a face-saving, partial deal as a live option even as a full resolution remains out of reach.

What would have to be true for this pricing to make sense? The market appears to believe that the ceasefire architecture is durable enough to prevent immediate escalation, but that the underlying political conditions — Iranian leverage over the strait, unresolved sanctions architecture, and U.S. domestic constraints ahead of midterms — make a comprehensive deal functionally impossible in the near term. The 18% probability on a U.S. invasion of Iran before 2027, ticking slightly upward, reflects a tail risk that is real but not the base case. The closure of Saudi airspace by year-end, now at 20% and rising, hints that traders see some probability of broader regional disruption even without full-scale war.

The tension the related markets reveal together is more instructive than any single number. Short-term transit is fine — ships are moving now — but the longer arc is deeply uncertain. The probability that the seven-day moving average of Hormuz transits recovers above normal before 2029 sits at 67%, implying that the money's base case is a multi-year disruption, not a quick fix. The 66% chance the U.S. announces an end to the Iranian blockade by March 2027 suggests a resolution path exists, but it likely runs through the post-midterm political window rather than through any deal this Congress could claim credit for.

For global energy markets, shipping insurers, and Gulf states watching their own airspace, the practical implication is that the current regime — ceasefires intact, traffic technically flowing at reduced or monitored levels, no formal agreement — is likely to persist well into next year. The path most consistent with the full picture the money is drawing: the Oman channel produces something limited and face-saving in the coming months, the U.S. and Iran maintain their informal truce, and Hormuz traffic limps along below normal levels without triggering a broader confrontation. What would break that read is a Saudi airspace closure or a collapse of the ceasefire — both of which the market assigns minority but non-trivial odds, and both of which would reprice everything else in a hurry.
