Strait of Hormuz traffic returns to normal by December 31?
I assess a 65% probability that IMF Portwatch will publish a 7-day moving average of Strait of Hormuz transit calls at or above 60 at least once by December 31, 2026, because historical traffic levels and the high baseline of tanker/container movement make a temporary or partial recovery likely, while geopolitical tail risks keep the probability well below certainty.
Analysis
Market-implied probability (~74% Yes) shows traders expect normalization and likely reflects a belief that the Strait's baseline traffic — driven mainly by tankers and bulk carriers — remains close enough to the 60 threshold that a return within months is plausible. With no fresh public data supplied here, the price suggests participants are pricing in easing of disruptions, rerouting reversals, or seasonal demand increases before year-end. Historical context matters: in pre-crisis years the Strait regularly handled daily arrivals that produced weekly averages at or above 60, so a one-time or short run-up to the threshold is statistically feasible even if the current daily numbers are somewhat depressed. That baseline makes a single qualifying week by Dec 31 a realistic outcome without requiring a full, sustained normalization of shipping patterns.
Geopolitical and security dynamics are the main source of downside risk; intermittent attacks, military escalations, or extended sanctions on a Gulf producer can sharply reduce transits and discourage voyages through the Strait for sustained periods. Conversely, improvements such as negotiated ceasefires, de-escalation steps, or commercial workarounds (e.g., higher insurance coverage, convoying arrangements, or substitution of routes back through the Strait) can restore throughput quickly and push a 7-day average above 60 for at least one week. Demand-side drivers, including seasonal refinery turnarounds, winter heating fuel flows in the Northern Hemisphere, or sudden spot cargo movements, can create short spikes in transits that would meet the market's condition even without a durable recovery.
Given the time window to Dec 31 and the relatively low bar of a single 7-day moving average meeting or exceeding 60, I place the probability above 50% but below market consensus to reflect persistent tail risks; therefore I estimate 65% Yes. This accounts for the fact that even a partial return to prior throughput levels or an isolated surge will suffice for resolution, while also recognizing that a significant geopolitical incident or prolonged sanctions could keep the weekly average below 60 for the remainder of the year.
Arguments
For
- Historical weekly arrival averages in non-crisis years were at or above the 60 threshold, so a return to those levels is operationally feasible.
- Short-term surges driven by seasonal demand or scheduled cargo movements can push a 7-day average above 60 without sustained normalization.
- Commercial risk mitigations such as higher insurance, convoying, or charter adjustments can quickly restore traffic through the Strait.
- Market participants appear to expect recovery (Yes priced at ~74%), reflecting available private information or risk appetite that could presage real-world normalization.
- OPEC+ output increases or the restoration of previously curtailed exports would rapidly increase tanker transits through Hormuz.
Against
- Ongoing or renewed geopolitical conflict involving Iran, proxy actors, or naval incidents could suppress or divert traffic for many months.
- Structural reductions in exports due to sanctions or long-term shifts in sourcing (e.g., buyers avoiding Gulf crude) could keep weekly averages below 60.
- High insurance costs and operator risk aversion may keep ships on longer alternative routes or induce cancellations, lowering transit counts.
- If IMF Portwatch reporting cadence or methodology changes unexpectedly, apparent numbers could lag actual traffic recovery and miss the threshold.
- Global demand shocks or large-scale fuel inventory buildups could reduce shipping volumes and eliminate short-term spikes that would otherwise qualify.
Key drivers
- Pre-crisis baseline traffic levels in the Strait, which historically produced weekly averages at or above 60, create a favorable statistical foundation for a recovery.
- Geopolitical de-escalation between Gulf actors or successful diplomatic interventions would rapidly reduce insurance and security premiums and restore routings through the Strait.
- Seasonal demand for oil and bulk commodities, especially northern-hemisphere winter needs and refinery scheduling, can produce short-term spikes in transits.
- Commercial adaptations — such as higher insurance coverage, convoying, or company-level route decisions — can bring traffic back through the Strait without full political resolution.
- OPEC+ production decisions and changes in crude export patterns materially shift tanker volumes transiting the Strait and can generate week-long surges.
- Operational constraints at Gulf ports or temporary closures elsewhere (e.g., Suez/Red Sea issues) can reroute vessels through Hormuz and temporarily raise transit counts.
Risk factors
- Renewed or escalated military activity in the Gulf, including missile or drone attacks on shipping, would suppress commercial transits for extended periods.
- Longer-term or tightened sanctions on regional exporters could structurally reduce crude shipments transiting the Strait over months.
- Persistent high insurance premiums and shipping industry risk aversion could keep vessels on longer alternative routings, lowering daily arrivals.
- Data gaps or reporting anomalies in IMF Portwatch or delayed publication could affect the apparent timing of any qualifying 7-day average.
- Significant global demand destruction (deep recession) or major drops in crude exports would reduce tanker calls below the threshold for extended time.
Scenarios
Best case
A combination of diplomatic de-escalation and operational mitigations (lower insurance rates, convoying, and port throughput increases) leads to a prompt rebound in tanker and general-cargo movements, producing one or more 7-day averages at or above 60 well before December 31, 2026.
Most likely
Intermittent security incidents and commercial adjustments alternate through the remainder of the year, but at least one week sees a rebound or spike in arrivals (driven by demand seasonality or export adjustments) that pushes the 7-day average to or above 60, yielding a Yes outcome.
Worst case
Persistent or escalating regional hostilities, tighter sanctions, and sustained shipping-company risk aversion keep traffic suppressed such that IMF Portwatch never records a 7-day moving average of 60 or above through December 31, 2026.
