Strait of Hormuz traffic returns to normal by December 31?
I think Yes is less likely than the market implies, with the chance at 43% given the renewed disruption and still-subnormal traffic.
Analysis
The latest week points to a fragile and uneven reopening rather than a clean normalization. Reuters reported that tanker traffic fell to a two-month low after renewed U.S.-Iran hostilities and vessel attacks, and another Reuters update said daily passages through the strait slid from 37 to 15 over a few days. That is well below the level needed to sustain a 7-day average at or above 60, so the market still needs a substantial rebound from current conditions.
The broader backdrop is somewhat better than it was in the spring, which keeps a Yes outcome alive. On July 8, the IMF said its forecast assumes the Strait of Hormuz begins reopening in mid-July and normalizes by March 2027, while Reuters described 36 commodity carriers transiting in a single day in late June, the highest level since the war began. That means the gap to 60 is not impossible to close if confidence returns quickly, but it still requires a meaningful expansion from the traffic levels seen in early July.
My independent view is that the market is still a bit too optimistic. The resolution only needs one qualifying 7-day average, so a sharp de-escalation could trigger Yes even without a full return to pre-war commerce, but the newest headlines point the other way: more incidents, more caution, and less traffic. The IMF and other multilaterals are explicitly warning that uncertainty remains high, which makes a year-end crossing above 60 plausible but not the base case.
Arguments
For
- A durable ceasefire or security arrangement could restore shipping confidence quickly enough for a brief 7-day spike above 60.
- The resolution uses a 7-day moving average, so a short burst of normal traffic is enough to trigger Yes even if conditions later weaken.
- Commercial traffic is still moving through the strait, which means a partial normalization can accelerate if insurers and operators believe the corridor is safe enough.
- The IMF itself expects reopening dynamics to begin in mid-July, which leaves several months for a recovery run-up before year-end.
Against
- The latest week showed renewed attacks and traffic at a two-month low, which argues against an imminent return to a 60-plus average.
- Recent daily transit counts in Reuters coverage were far below the threshold, including a sharp drop from the high 30s to the mid-teens.
- The IMF baseline only assumes full normalization by March 2027, which implies year-end 2026 may still be too early for sustained recovery.
- Any new toll, blockade, or incident near the strait could keep operators cautious and suppress the 7-day average below the trigger.
Key drivers
- Whether the current reopening holds long enough for operators to re-reroute vessels back through the strait.
- Whether fresh attacks or enforcement actions keep daily traffic trapped below the low-40s range.
- How quickly insurers, charterers, and port planners regain confidence that the route is commercially safe.
- The fact that the market only needs one qualifying 7-day average, not a permanent return to normal volumes.
Risk factors
- A single new vessel incident could trigger another wave of avoidance and push the average back down.
- Negotiations over security, fees, or navigation rights could stall even if overt fighting eases.
- Traffic may recover in bursts but remain too volatile to hold above 60 for a full week.
- If reopening proves gradual, the market could run out of time before a sufficiently strong recovery appears.
Scenarios
Best case
A sustained ceasefire and improved maritime security restore confidence quickly, daily transits climb back toward the late-June highs, and the 7-day average briefly clears 60 well before December 31.
Most likely
Traffic improves unevenly but remains volatile, with occasional rebounds offset by security scares, leaving the year-end probability of a qualifying 7-day average below even but not remote.
Worst case
Renewed attacks or blockade-style enforcement keep insurers and shippers cautious, traffic stays in the 20s to 40s, and no 7-day average ever reaches 60 before year-end.

The data and policy environment point strongly against a sustained or one‑off 5%+ quarter, though low‑probability shocks could still produce a spike.
