Strait of Hormuz traffic returns to normal by December 31?
I see this as a near-even but slightly negative proposition, with a roughly one-in-two chance that IMF PortWatch shows a 7-day average of at least 60 before year-end. The market looks a bit too optimistic given how far current traffic is from the threshold and how much has to go right operationally.
Analysis
The decisive fact is that current Strait of Hormuz traffic is still nowhere near the level required for a Yes resolution. The market needs a 7-day moving average of 60 or more transit calls in IMF PortWatch data, and recent readings described in the news flow are only around the mid-single digits, with some trackers still characterizing conditions as severely restricted. That means the strait would need a very large and sustained rebound, not just a brief improvement, and there is still no evidence in the reported data that traffic has moved close to the resolution threshold.
The main reason to believe Yes is still possible is that the remaining time window is long enough for a rapid normalization if diplomacy succeeds. Reports of Iran and Oman discussing a passage arrangement, together with a U.S. official saying normal oil traffic could resume soon, suggest that the political conditions for a sharp rebound are at least plausible. Because the resolution trigger is only a 7-day average, a credible security or transit agreement could move the metric quickly if shipping companies, insurers, and operators react promptly and volume snaps back toward the historical baseline.
The reason I still lean slightly against Yes is that diplomatic optimism has not yet translated into sustained commercial normalization. A temporary corridor, partial de-escalation, or limited passage arrangement may improve conditions without lifting traffic all the way back to a 60-plus average, and shipping often responds cautiously even after announcements because crews, insurers, and cargo owners want proof that disruptions are over. With traffic currently so depressed, the market needs not just a deal but a durable operational reset before December 31, and that execution risk is substantial enough that I rate the outcome a bit below the current market price.
Arguments
For
- Arguments for Yes: A successful passage arrangement could trigger a rapid snapback in vessel movements and push the 7-day average above 60 quickly.
- Arguments for Yes: The threshold is based on a short moving average, so a brief but strong normalization period is enough to resolve the market to Yes.
Against
- Arguments against Yes: Current traffic remains far below normal, and the gap to a 60-call average is still extremely large.
- Arguments against Yes: Diplomatic progress has not yet proven that shipping will return at a durable, unrestricted commercial scale.
Key drivers
- Traffic is currently far below the 60-call threshold, so the market needs a dramatic and sustained recovery rather than a marginal improvement.
- Active diplomacy involving Iran, Oman, and U.S. messaging creates a realistic path to a fast rebound if an arrangement is implemented.
- The 7-day average rule makes the outcome sensitive to short-term surges, which helps Yes if normalization happens quickly.
- The December 31 deadline leaves several months for a shift, but not enough time for slow or partial recovery to count.
Risk factors
- A diplomatic breakthrough could remain partial and fail to restore ordinary commercial traffic to the required level.
- Shipping firms may wait for clear security and insurance conditions before returning vessels at scale.
- Renewed interruptions or a lack of verified IMF PortWatch data close to year-end could prevent the moving average from ever reaching 60.
- Even if traffic improves, it may do so too slowly to lift the 7-day average above the threshold before the deadline.
Scenarios
Best case
A concrete security or transit agreement is implemented soon, shipping confidence returns quickly, and IMF PortWatch records a sustained rebound that lifts the 7-day average to 60 or higher well before December 31.
Most likely
There is some improvement in sentiment and perhaps a partial traffic rebound, but normalization remains incomplete or too inconsistent for the 7-day average to reach 60 before the deadline.
Worst case
Talks stall or produce only a limited arrangement, traffic remains depressed or erratic, and the 7-day average never comes close to the required level by year-end.

How many Emmys will “DTF St. Louis” win?
AI41%MKT98%Edge-57HypedDTF St. Louis has enough nomination strength and category-level upside that a 2-plus win outcome is very live, so I do not think the 0-or-1 bracket is close to certain. My read is that 0 or 1 wins is a modest underdog relative to the market price, not a near-lock.
