Summary The probability of the 7-day moving average of transit calls through the Strait of Hormuz exceeding 60 as reported by the IMF PortWatch before December 1, 2026, is estimated at 53%. Currently, transit calls are near zero following a recent halt in traffic and a formal closure by the IRGC on June 6, 2026. Peace negotiations are presently stalled, making near-term normalization practically impossible. Even if a diplomatic resolution is reached in the near future, the physical and administrative processes required to restore normal shipping operations will introduce a substantial delay of at least 30 to 60 days. This lag is largely driven by the need for extensive mine-clearing operations—which alone are estimated to take around 30 days—as well as the time required to address heightened insurance concerns and clear a massive backlog of roughly 1,500 stranded vessels. However, the December 1 timeline provides a nearly six-month window. This longer horizon offers a realistic timeframe for both political agreements to be finalized and the subsequent logistical hurdles to be cleared, contrasting sharply with the near-zero probabilities for normalization in June or July. Furthermore, while the economic imperative to reopen the Strait of Hormuz is massive given its critical role in global energy markets, the structural limitations of the IMF PortWatch tracker must be factored in. The tracker relies on Automatic Identification System (AIS) data, which structurally undercounts vessels navigating "dark" (with transponders off) due to regional security concerns. This measurement constraint slightly dampens the probability of officially recording an average above 60, even if physical traffic volumes recover robustly. Weighing the extended timeframe against the severe current escalation and logistical lag times yields a slight edge toward the threshold being met before December.
Strongest Arguments for Yes
- Extended time horizon: The December 1, 2026 deadline is nearly six months away, offering sufficient time for stalled diplomatic talks to resume, a ceasefire to be implemented, and the multi-week logistical recovery to be completed.
- Massive economic imperatives: The Strait of Hormuz is the world's most critical chokepoint for global oil supplies, creating immense international pressure and powerful economic incentives for all involved actors to restore commercial traffic as swiftly as possible.
- Feasible recovery curve: If a political resolution is achieved by late summer or early autumn, the estimated 30 to 60-day operational lag for mine-clearing and insurance adjustments fits comfortably within the December timeframe, allowing the 7-day moving average enough time to surpass the threshold of 60.
Strongest Arguments for No
- Current escalation and political stagnation: The recent IRGC closure on June 6 and the total halt in traffic—with zero transits recorded over recent 72-hour periods—underscore a severe deterioration in security, while peace talks remain firmly stalled.
- Protracted logistical delays: Even after a political breakthrough, restoring normal operations will be arduous. Clearing the backlog of 1,500 stranded ships and conducting thorough mine-clearing operations will create massive, enduring bottlenecks.
- Measurement constraints: The IMF PortWatch tracker relies on AIS data, which structurally undercounts ships that turn off their transponders to mitigate security risks. This "dark" shipping makes it significantly harder to officially record a 7-day moving average above 60, even if physical traffic begins to normalize.
Key Uncertainties
- Trajectory of peace negotiations: Whether, and how quickly, the currently stalled diplomatic efforts can yield a credible and lasting agreement will determine when the clock can even start on logistical and physical recovery.
- Speed of physical mine-clearing: The actual time required to ensure safe passage through the strait could stretch well beyond the estimated 30 days if operations face technical difficulties or subsequent security disruptions.
- Re-establishment of maritime insurance: How quickly insurers are willing to provide coverage at commercially viable rates, and how soon shipping companies feel safe enough to resume regular routes, will dictate the pace at which transit volumes recover to the threshold of 60.
