Strait of Hormuz traffic returns to normal by August 31?
I put the chance of a return to normal traffic by August 31 at 18%. The strait is still operating well below the 60-call threshold, and the latest week of attacks makes a sustained recovery look less likely than the current market price implies.
Analysis
The latest traffic readings still look far below what this market needs. A PortWatch-based live monitor puts Strait of Hormuz ship arrivals at about 32 per day on a 7-day average, roughly 44% of the pre-crisis level, while Reuters-linked vessel tracking reports traffic in the 25 to 40 ship range over the last week and 48 ships on July 8 versus 47 on July 7. That is still a wide gap from the 60-call threshold, and because the market resolves on a 7-day moving average, it would require a sustained step-up rather than a brief rebound.
The recent news flow is still adverse for a near-term normalization. In the past few days there have been renewed attacks on tankers, at least four oil and gas tankers turned back from attempting to transit, and maritime authorities have urged caution or even suspension of Hormuz transits unless safety can be assured. Reuters also reported that traffic slowed again on Friday after the latest round of hostilities, which suggests the security shock has not yet fully passed through the shipping system.
There are some reasons not to write off a recovery entirely. The U.S. and Iran are still holding technical and mediated talks focused on shipping flows, and Reuters said no fresh attacks were reported on Friday, so there is still at least a diplomatic off-ramp. But the key point is timing: even if talks improve in the next week or two, the strait would need a fairly rapid and durable normalization to lift a 7-day average from the low 30s into the 60s by August 31. That is possible, but it is the less likely path given the current security environment and the inertia in shipping and insurance decisions.
Arguments
For
- Arguments for Yes: Ongoing technical and Omani-mediated talks leave open a pathway to a quick de-escalation that could restore shipping confidence.
- Arguments for Yes: The corridor is not fully shut, and some vessels are still transiting, so traffic could rebound sharply if the security premium drops.
Against
- Arguments against Yes: The observed 7-day traffic level is only around 32 per day, far below the 60-call requirement.
- Arguments against Yes: The latest attacks, turn-backs, and IMO caution suggest shipowners and insurers may keep routes suppressed even if headline diplomacy improves.
Key drivers
- Whether U.S.-Iran talks produce a credible public guarantee that attacks on commercial shipping will stop.
- How quickly insurers and ship operators regain confidence after the July attacks.
- Whether daily arrivals can rise and stay above 60 long enough for the 7-day average to clear the threshold.
- Whether any fresh incident resets the risk premium and pushes more ships to delay, reroute, or go dark.
Risk factors
- A new strike on a tanker or military escalation could keep traffic trapped well below normal.
- Negotiations could stall, leaving operators with no assurance that the strait is safe enough for a sustained recovery.
- AIS-dark sailing and cautious routing could keep reported PortWatch counts depressed even if some cargo continues moving.
- The 7-day average could improve briefly but still fail to stay above 60 before the August 31 cutoff.
Scenarios
Best case
A durable ceasefire and shipping security understanding emerges in July, insurers relax quickly, and daily arrivals jump back toward pre-crisis levels long enough for the 7-day average to clear 60 by late summer.
Most likely
Traffic recovers somewhat from the current shock but remains volatile and below the threshold, with intermittent diplomatic progress offset by lingering security concerns and no sustained 7-day average at or above 60.
Worst case
Attacks continue or resume, carriers keep turning back or routing cautiously, and the 7-day average remains stuck in the 20s or 30s through August 31.

Will a cabinet member be impeached?
AI97%MKT5%Edge+92Hidden Gem**Very likely Yes.** A sitting Cabinet member (Philippine Vice President Sara Duterte) is already being tried in the Senate impeachment court, which in the Philippines follows a House impeachment — so the factual threshold for “impeached” has effectively been met and the probability of at least one Cabinet member being impeached before 2027 is extremely high.
