Strait of Hormuz traffic returns to normal by December 31?
I think the market is somewhat overpriced on Yes. The Strait is still operational and the IMF now assumes reopening begins in mid-July, but the latest week brought renewed attacks, tanker turnbacks, and official traffic counts that still look far below the 60-call threshold.
Analysis
The key point is that this is not a full-normalization question; it only needs IMF Portwatch to print a 7-day moving average of 60 or more at any time before year-end. That is materially easier than returning to prewar traffic, and the IMF’s own July 8 outlook explicitly assumes the Strait of Hormuz begins reopening in mid-July, with conditions normalizing only by March 2027. On that framing, a 60-plus rolling average before December 31 is plausible if the reopening actually holds.
The recent data, however, are still ugly. Reuters reporting over the last few days describes fresh attacks on vessels, U.S. retaliation, and tankers turning back from attempted transits, which is exactly the kind of behavior that suppresses the rolling average. PortWatch-linked reporting cited in the press suggests the most recent official daily counts were still only in the 30s to 40s, far short of the 60 threshold, and S&P Global said July 7 traffic was only modestly different from July 8 despite the attacks, which implies the recovery is fragile rather than complete.
My read is that the market is pricing in a decent chance of a diplomatic stabilization that restores shipping confidence later this year, but the path is much less certain than the headline probability suggests. Reuters also noted that Gulf exports had improved and backlog was clearing, which supports the idea that traffic can rebound quickly if security improves. Still, with renewed violence only days ago, the near-term trend is bearish for the threshold and the market needs a sustained move, not just a one-day spike, to qualify.
Arguments
For
- Arguments for Yes: The IMF’s July 8 forecast assumes the Strait of Hormuz begins reopening in mid-July, which leaves ample time for a 60-plus rolling average to appear before December 31.
- Arguments for Yes: Reuters reporting shows some cargo and energy traffic has continued, backlog has been clearing, and Gulf exports have been recovering from the war shock.
- Arguments for Yes: If security improves even modestly, the rolling 7-day average could rise quickly because the threshold is well below prewar traffic and does not require a full return to normal.
Against
- Arguments against Yes: Fresh attacks on ships in the Strait of Hormuz over the last week have increased insurance, security, and routing caution, which directly pushes traffic lower.
- Arguments against Yes: The latest PortWatch-linked daily counts cited in press coverage are still in the 30s to 40s, meaning the market is starting from a wide gap versus the 60 threshold.
- Arguments against Yes: Tankers turning back from attempted transits show that operational confidence is still weak, so the market needs a sustained improvement rather than a brief rebound.
Key drivers
- Whether the U.S.-Iran ceasefire and reopening timeline actually hold after the latest attacks.
- How fast shipowners and insurers restore confidence in transiting the strait.
- Whether Portwatch daily traffic can climb and stay above roughly 60 for a full week, not just for a single day.
- Whether diplomatic pressure reduces the incentive for further attacks during the second half of 2026.
Risk factors
- A renewed escalation could keep vessel counts depressed well into the autumn.
- Even if traffic improves, another attack could knock the 7-day average back below 60 before the market resolves.
- The market depends on IMF Portwatch specifically, so apparent activity in other trackers would not matter unless it appears in the official series.
- If diplomatic talks stall, shipping confidence may never recover enough in 2026 to produce a qualifying week.
Scenarios
Best case
The latest attacks prove isolated, diplomacy stabilizes the corridor, insurers loosen restrictions, and traffic climbs through the summer so that the Portwatch 7-day average reaches 60 before the end of the year.
Most likely
Traffic slowly recovers but remains choppy, with intermittent disruptions preventing a clean sustained break above 60 for long enough to be obvious, leaving the market close to a coin flip but slightly favoring Yes.
Worst case
Attacks, retaliation, and tanker diversions persist, keeping daily counts in the 30s and 40s or lower, so the 7-day average never reaches 60 by December 31.
