Strait of Hormuz traffic returns to normal by December 31?
The market still looks somewhat too optimistic. Recent traffic recovery has stalled amid renewed attacks, and PortWatch remains far below the 60-call threshold, so I put Yes below the current price.
Analysis
The most important near-term datapoint is that IMF PortWatch was reportedly updated through July 5 and the latest peak 7-day average was 35, only slightly above the prior revised peak of 31. That is still far below the 60-call trigger, so the market needs a large additional recovery rather than a modest continuation of the recent bounce.
The security backdrop worsened again over July 6 to 8. The IMO condemned fresh attacks on commercial ships in the Strait of Hormuz, said hundreds of ships and around 6,000 seafarers remain stranded, and urged operators to avoid transiting unless safety can be assured, while S&P Global reported that attacks, dark sailing, and an elevated threat environment continued to distort routing. That combination is much more consistent with a fragile, conflict-driven partial reopening than with a clean return to normal traffic.
There is still a plausible recovery path because ships are not completely absent from the strait, June traffic was materially higher than May in Lloyd’s List Intelligence data, and U.S. officials are still pressing Iran to publicly guarantee safe passage while negotiations continue. My inference is that the balance now depends less on whether the strait is technically open and more on whether a durable de-escalation emerges soon enough for carriers to resume routine routing and insurance behavior before year-end.
Against that, the current market price of 62.5% for Yes seems to assume a fairly strong recovery from here. Given the latest attacks and the still-low PortWatch peak, I think a 60-plus 7-day average by December 31 is more likely than not only if the ceasefire holds and confidence returns quickly; otherwise the waterway can stay stuck in the 30s or 40s for a long time.
Arguments
For
- Arguments for Yes: The strait is still operating, so a sustained easing in security conditions could allow traffic to rebound above 60 without needing a formal reopening.
- Arguments for Yes: Diplomatic pressure is active, and U.S. officials are still trying to secure an explicit Iranian guarantee that the waterway is safe for shipping.
- Arguments for Yes: June traffic already rebounded sharply from May, which shows the system can recover quickly when risk perception improves.
Against
- Arguments against Yes: The latest reported PortWatch peak is only 35, leaving a very large gap to the 60 threshold.
- Arguments against Yes: Fresh attacks and IMO warnings indicate carriers may continue to avoid normal routing or sail dark, which suppresses the measured average.
- Arguments against Yes: The situation is still volatile enough that even temporary progress can be reversed quickly by another incident.
Key drivers
- Whether the post-July 5 PortWatch trend keeps climbing or rolls over after the latest attacks.
- Whether the ceasefire and diplomacy become durable enough to restore routine carrier confidence.
- Whether insurers and operators stop treating the Strait of Hormuz as a severe-risk transit corridor.
- How quickly backlog traffic and postponed sailings return if the security environment stabilizes.
Risk factors
- A new attack could push traffic lower for weeks and reset sentiment among carriers and insurers.
- PortWatch’s lagged publication schedule could mean the market stays below threshold for longer than real-world anecdotes suggest.
- If the conflict persists at a low boil, shipping may remain fragmented enough to prevent a sustained 60-plus 7-day average.
- Escalation in U.S.-Iran retaliation could interrupt the recovery path even if traffic briefly improves.
Scenarios
Best case
A durable de-escalation takes hold in the coming weeks, carriers normalize routing and insurance behavior, and PortWatch crosses 60 on a 7-day average well before year-end.
Most likely
Traffic gradually recovers but remains uneven for months, which makes a temporary 60-plus print possible yet still less likely than the current price implies.
Worst case
Another round of attacks or a breakdown in talks keeps the Strait on a severe-risk footing, traffic stays suppressed in the 30s or 40s, and the market resolves No.

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.
