Strait of Hormuz traffic returns to normal by December 31?
I assign a 46% chance of Yes. The latest week shows traffic weakening sharply again and military escalation worsening the operating environment, even though a year-end rebound is still plausible if diplomacy stabilizes the strait.
Analysis
The newest reporting from July 8 through July 15 points to deterioration, not normalization. Reuters reported tanker transits falling to a two-month low and commercial traffic continuing at reduced levels, while S&P Global said the strait saw 48 ships on July 8 versus 47 on July 7. Reuters later reported only six vessels transited on Sunday, the lowest number in five weeks, and AP reported today that the U.S. reimposed a naval blockade and intensified strikes after renewed attacks on ships. That is a very poor near-term setup for a 7-day moving average to stay at or above 60.
At the same time, the threshold is not full prewar normality, so a partial recovery could still be enough. Reuters reporting from early July said average daily commodity-vessel traffic was in the 25 to 40 range in the prior week, with a peak of 59 on June 24, and before the conflict the waterway handled about 125 sailings per day. USNI also noted that traffic since the ceasefire had not yet become the new normal, but it was still materially above the worst disruption seen earlier in the war. That means a durable easing of hostilities could plausibly push the 7-day average over 60 without needing a complete return to prewar conditions.
My overall read is that the market is somewhat optimistic about the speed of stabilization. The current pattern looks more like a managed conflict with intermittent attacks, route changes, and ships switching off transponders, which can keep the published Portwatch average suppressed even when some vessels still move. There are still diplomatic channels open, including Oman-mediated talks on safe passage, so Yes is far from dead, but the latest escalation makes it more likely that the strait remains below the qualifying level for long stretches before year-end.
Arguments
For
- Arguments for Yes: The threshold is only 60, which is well below the roughly 125 daily sailings seen before the conflict, so a partial normalization could qualify quickly.
- Arguments for Yes: Oman-mediated talks and prior ceasefire arrangements show that shipping can rebound quickly once security improves.
- Arguments for Yes: Traffic has not collapsed to zero, so there is still a live base of transits that could expand if insurers and shipowners regain confidence.
Against
- Arguments against Yes: The most recent data show traffic falling to a two-month low and only six visible vessels on Sunday, well below the 60 threshold.
- Arguments against Yes: The U.S. blockade and renewed strikes increase the odds that shipping stays constrained for weeks rather than recovering steadily.
- Arguments against Yes: Shipping behavior is still defensive, with dark crossings and transponders switched off, which is consistent with caution rather than a stable normal.
Key drivers
- The pace and durability of U.S.-Iran de-escalation will likely decide whether traffic can climb above 60.
- The frequency of attacks on commercial vessels around the strait will determine how quickly shipowners and insurers restore normal routing.
- Whether visible transits recover enough to keep the 7-day moving average above 60 for a full week is the immediate mechanical hurdle.
- The level of route concealment and AIS-off behavior can suppress published counts even when some cargo is still moving.
Risk factors
- A fresh attack on a tanker or container ship could trigger another sharp drop in traffic and delay recovery into late 2026.
- A prolonged blockade or expanded military campaign would make it much harder for the moving average to regain 60.
- If vessels continue to sail dark or reroute around the danger zone, Portwatch may undercount traffic for long enough to prevent qualification.
- Even if the route partially recovers, repeated stop-start violence could keep the 7-day average below the threshold for most of the remaining year.
Scenarios
Best case
A durable ceasefire or maritime security deal takes hold in late summer or autumn, attacks stop, shipowners resume normal routing, and the 7-day average rises above 60 long enough to resolve Yes before year-end.
Most likely
Traffic remains volatile and below the threshold for several more weeks, with occasional rebounds but no sustained return to normal until later in the year, leaving the market close to a coin flip but slightly biased toward No.
Worst case
The blockade and retaliatory strikes continue, traffic stays depressed or dark, and the 7-day moving average never reaches 60, producing a No resolution.

2026: Trump's dream year?
AI72%MKT6%Edge+66Hidden GemGiven that the three policy pillars of the bull case (tax cuts/deregulation, likely Fed rate cuts, and a weakening of regulatory restraints via the Supreme Court) are already in place, the outcome now primarily hinges on the 2026 midterms and a small residual macro/geo risk; I assess a substantially higher chance of the bull case occurring than the market does.

Next Claude Opus released by...?
AI41%MKT97%Edge-56HypedThe market is pricing in a near-certain August Opus launch, but Anthropic's public materials still show Opus 4.8 as the current Opus model and there has been no official new Opus announcement in the past week. I think the true probability is much lower than the market's 97.55% implied price.
