Hormuz Traffic Remains Paralyzed Through September

The Strait of Hormuz, the narrow chokepoint through which roughly a fifth of the world's oil supply passes, is all but certain to remain disrupted through September 30. The money tracking this situation has collapsed the odds of a near-term normalization to 1% — a reading that amounts to a statement of fact, not a forecast.

What makes the picture more than a simple tale of paralysis is the divergence between the short-term and the longer arc. The near-term market is settled; what the related markets reveal together is a more consequential story about what comes next. A diplomatic meeting between the United States and Iran is increasingly favored to occur before the end of 2026 — the odds now sit at 63% and moved sharply upward in the past day. Separately, the odds that no qualifying diplomatic meeting happens before September 30 stand at 90%, suggesting that any breakthrough is expected to come in the final stretch of the year, not imminently. The money is not predicting a quick fix; it is pricing a slow, negotiated exit from the crisis.

The deeper, more liquid market at Kalshi — running roughly seven times the daily volume of Polymarket on the question of who holds the chief U.S. negotiating role — prices Steve Witkoff's involvement in a formal diplomatic session at 34%, meaningfully above Polymarket's 27%. The venues disagree, and the reason is not clear from the signal alone. What the gap does suggest is that there is genuine uncertainty about the mechanics of any diplomatic engagement, even as the broader picture favors one eventually occurring. The odds of a full U.S. invasion of Iran remain low at 16%, and the Iranian regime is seen as very unlikely to fall before 2027, sitting at 6%. Kharg Island, Iran's main crude oil export terminal, is priced at just 6% to change hands. The military levers, in other words, are not what traders expect to resolve this.

The collapse from a peak of 30% probability for Hormuz normalization — reached roughly six weeks ago — to today's 1% tracks the failure of early diplomatic feelers to produce any concrete agreement. The Israel-Iran ceasefire, holding at 92% to continue through September, has removed one acute flashpoint, but it has not translated into pressure on Iran to reopen the strait. Enriched uranium transfer to the U.S. is priced at just 6% by year's end, implying that the core nuclear dispute remains far from resolved and that Iran retains its leverage.

Longer-dated markets provide a fragile note of optimism: transit calls through the strait are favored at 68% to recover above meaningful thresholds before 2029, and a U.S. announcement formally ending the Iranian blockade is priced at 60% by December 31, 2026. That combination sketches the path the money finds most plausible — a negotiated de-escalation arriving in the back half of this year, followed by a gradual, months-long restoration of shipping. It is not a rescue; it is a managed climb down.

For energy markets, shipping insurers, and the governments of oil-importing nations, the calculus is stark. The strait's disruption is not a temporary shock to be waited out but an extended constraint that the money now treats as the baseline for the rest of 2025 and well into 2026. The scenario most likely to break that read — a rapid diplomatic agreement producing verifiable Iranian concessions before September — is precisely what the odds currently discount. Any sign that Witkoff or another senior U.S. envoy has secured a formal meeting with Iranian counterparts would be the earliest signal that the consensus is cracking.
