Hormuz Shipping Disruption Likely Extends Well Into 2025

The Strait of Hormuz, the narrow chokepoint through which roughly a fifth of the world's seaborne oil passes, is very likely to remain disrupted through the end of November — and the money that has tracked this situation for nearly two months now puts the odds of a return to normal traffic at just 8%, down from a peak of 30% set almost two months ago. The slide has been steady and the current reading sits at the lowest point since tracking began.

What makes this reading analytically striking is the context surrounding it. A US-Iran ceasefire is holding with virtual certainty through early October, and an Israel-Iran ceasefire is similarly intact. The Iranian regime itself appears stable: the probability of leadership change before mid-2027 sits at roughly 22%, and the odds of the regime falling before 2027 are a negligible 4%. Mojtaba Khamenei looks very likely to remain the dominant figure in Tehran through year-end. In other words, the disruption to Hormuz traffic is not the product of all-out war or imminent collapse — it is persisting precisely because the situation has settled into a managed, tense equilibrium that removes any urgency for either side to restore normalcy.

The most plausible read of this pricing is that Iran is using restricted Hormuz access as durable leverage — not a weapon of last resort, but a negotiating card held deliberately in hand. A US-Iran final nuclear deal by the end of 2026 is now at only 14%, barely moved in recent days despite high volume, suggesting that the diplomatic path remains real but distant. The 68% probability that the US announces a formal end to an Iranian blockade by March 2027 implies the money does see resolution eventually — but on a timeline that extends well past the November 30 window. The near-term and the longer arc are not contradictory; they describe a protracted standoff with a negotiated exit somewhere on the far horizon.

What led here is a combination of forces that have compounded over roughly two months of observation. US maximum-pressure tactics, including sanctions and naval posturing, have not dislodged Tehran's willingness to restrict traffic. Iran, facing economic strain but no existential military threat, has calculated that it can absorb the standoff longer than Washington or its partners can tolerate elevated energy prices and shipping insurance costs. The ceasefire frameworks, while stabilizing in one sense, have paradoxically reduced the pressure to resolve the underlying dispute: neither side is being forced toward a reckoning.

For global energy markets, shipping insurers, and the economies of importing nations — particularly in Asia — the persistence of disruption through the end of the year carries concrete costs that compound with each passing week. Rerouting around the Cape of Good Hope adds time and expense; spot tanker rates remain elevated; and the uncertainty premium baked into oil prices does not dissolve until traffic actually resumes. The 1% probability of normalization by October 31 closes that door entirely for the near term.

The market's most telling internal tension is between the ceasefire stability readings and the Hormuz normalization odds. The ceasefires holding is good news for avoiding escalation; it is not good news for Hormuz reopening, because it removes the crisis pressure that might otherwise force a grand bargain. The path the money finds most plausible runs something like this: the ceasefire holds, nuclear talks inch forward without breakthrough, and Hormuz traffic remains constrained until a broader US-Iran arrangement — the kind the 68% blockade-end market gestures toward — materializes sometime in 2026. The scenario that breaks this read is a diplomatic acceleration that the current nuclear-deal odds do not yet support, or a domestic shock inside Iran that the regime-stability markets firmly discount. Until one of those shifts, the strait stays closed to normal commerce, and the costs accrue quietly, month by month.
