Strait of Hormuz traffic returns to normal by September 30?
The odds of traffic reaching the required IMF PortWatch threshold by September 30 look below one in three. The strait is still operating well under normal levels, and the recovery needed to clear a 7-day average of 60 is substantial.
Analysis
The central issue is the gap between current traffic and the resolution threshold. Recent readings cited in the news flow are still around the 30s at best, with some days much lower, while the market requires the 7-day moving average to reach at least 60. That is not a minor improvement; it is a large and sustained increase in actual transit calls, and the market does not resolve on the basis of the strait merely being open or on occasional higher-traffic days.
There is a plausible path to Yes if shipping confidence improves quickly. The corridor is still passable, commercial transits have not stopped entirely, and the waterway is strategically important enough that a broad recovery could happen if security concerns ease and insurers, operators, and regional actors all become more comfortable. With roughly eight weeks left, a late surge is possible, and because the resolution metric is a rolling average, a few strong weeks in a row could be enough to cross the line.
Still, the balance of evidence points the other way. Major shipping behavior tends to lag political messaging, and the recent reports suggest continued caution rather than a full return to normal routing. The extension of force majeure on LNG shipments is especially important because it indicates that at least some large operators still see meaningful risk beyond the market deadline. Given the high threshold, the short remaining window, and the fact that traffic is still far from 60, No looks more likely than Yes even if the market may be assigning some value to a sharp rebound scenario.
Arguments
For
- The strait remains open to commercial shipping, so a rebound is operationally possible if confidence improves.
- Recent traffic has shown some recovery from very low levels, suggesting the trend is not completely stagnant.
Against
- Current traffic is still well below the 60-call threshold, so the market needs a large and sustained increase in a short time.
- Extended force majeure and continued caution from shippers imply that full normalization may not arrive before September 30.
Key drivers
- Current transit levels are still far below the 60 threshold required for resolution.
- The 7-day moving average needs sustained recovery, not just a brief spike in ship calls.
- Security, insurance, and routing decisions by major carriers can change traffic quickly if confidence returns.
- The deadline is close enough that any recovery must happen soon and persist for several weeks.
Risk factors
- A sudden de-escalation in regional tensions could trigger a fast return of commercial traffic.
- Major operators could reroute back through the strait faster than expected if escort and security conditions improve.
- The market could resolve Yes on a temporary but sustained surge if vessel counts rise sharply in late August or September.
- Official openness of the strait may translate into actual ship volume faster than recent data suggests.
Scenarios
Best case
Geopolitical tensions ease quickly, insurers and major carriers regain confidence, and traffic climbs steadily enough for the 7-day average to reach 60 before the end of September.
Most likely
Traffic improves somewhat from current depressed levels but stays short of normal, leaving the 7-day average below 60 when the market deadline arrives.
Worst case
Traffic remains stuck below the mid-50s, disruptions or caution persist, and the rolling average never gets close enough to satisfy the threshold.

Which party will gain most seats in Russian Parliamentary Election?
AI12%MKT65%Edge-53HypedUnited Russia is likely to remain the dominant party in total seats, but this market is about which party gains the most seats versus its current baseline. On that definition, a Yes outcome looks unlikely because United Russia is starting from a very high seat count and current projections point to losses rather than gains.
