Strait of Hormuz traffic returns to normal by December 31?
The probability of Strait of Hormuz traffic returning to normal (≥60 daily arrivals) by December 31, 2026 is approximately 42%, as the current near-zero traffic, 80 uncleared mines, active US naval blockade, and renewed US-Iran fighting create severe structural barriers that likely prevent a full recovery within the five-month window.
Analysis
The Strait of Hormuz is currently effectively closed to normal commercial shipping, with daily transits collapsed to near zero (0–2 tankers) compared to a pre-crisis baseline of 60–140 vessels. As of July 12, 2026, only 10 commercial vessels were recorded, representing less than 2% of normal traffic, while over 150 ships remain stranded in the Gulf of Oman and Persian Gulf awaiting clearance. The central route is physically obstructed by an estimated 80 mines that require clearing, and recent attacks have disabled AIS transponders on many vessels, making accurate tracking and safe passage impossible without significant remediation efforts that have not yet begun.
The geopolitical environment has deteriorated sharply, with renewed fighting between the US and Iran causing traffic to grind to a halt and the IRGC declaring the strait closed until the end of US interference. President Trump reinstated a US naval blockade on Iranian shipping effective July 14, 2026, which restricts specific traffic lanes and complicates coordination for any potential recovery. Although Oman has issued a temporary, coordinated traffic plan with controlled, phased movements, this represents a safety protocol rather than normal routing, as vessels must travel in groups through scheduled holding areas rather than following standard commercial patterns.
The market resolution criteria require a 7-day moving average of at least 60 arrivals, which demands a return to approximately 60 daily vessels—far above current levels of 0–2. While war insurance is available, ship masters refuse transit due to crew safety risks, and major operators like Mitsui OSK Lines state they will not resume transits until the strait is proven safe in practice. The US White House claims the Strait is open and oil is flowing, but this contradicts data showing no VLCC or LNG tankers have passed for two consecutive days recently, indicating official statements may be politically motivated rather than reflective of actual conditions.
Historical context suggests that even after the June 17 interim peace deal, traffic averaged only 28 ships per day in the first 18 days, far below the pre-war average of 88 per day. The breakdown of the truce on July 8 and subsequent escalation mean that the conditions for recovery are worse than during the brief reopening period. With only five months remaining until December 31 and the current trajectory showing continued decline rather than improvement, the structural barriers of mine clearance, safety guarantees, and blockade removal create a low probability of achieving the required threshold.
Arguments
For
- Five-month window provides time for potential diplomatic resolution and mine clearance
- Oman's temporary coordinated traffic plan demonstrates some operational continuity exists
- War insurance availability reduces financial barriers for willing operators
- Precedent of traffic recovery after June 17 interim deal shows recovery is possible under favorable conditions
- Global energy market pressure may force accelerated resolution of the crisis
Against
- Current traffic at less than 2% of baseline with 0–2 daily transits versus required 60
- 80 mines physically blocking the central route with no confirmed clearance timeline
- US naval blockade actively restricting traffic lanes and complicating coordination
- Ship masters refusing transit due to crew safety risks regardless of insurance availability
- Truce breakdown on July 8 and renewed fighting indicate deteriorating rather than improving conditions
Key drivers
- Physical obstruction by 80 uncleared mines blocking the central route
- Active US naval blockade on Iranian shipping reinstated July 14, 2026
- Renewed US-Iran fighting causing traffic to collapse to near zero
- Ship masters refusing transit due to crew safety risks despite available insurance
- Resolution threshold requiring 60 daily arrivals versus current 0–2 levels
Risk factors
- Unexpected rapid mine-clearing operation by international coalition
- Sudden diplomatic breakthrough leading to immediate blockade removal
- Iran unilaterally declaring the strait open and guaranteeing safety
- Major shipping companies resuming transits despite safety concerns
- Data integrity issues or erroneous IMF Portwatch reporting inflating numbers
Scenarios
Best case
A rapid diplomatic breakthrough between the US and Iran leads to immediate blockade removal, Iran guarantees safety for all commercial vessels, and an international coalition clears the 80 mines within weeks, allowing traffic to surge to 60+ daily arrivals by September 2026.
Most likely
Traffic gradually improves to 20–30 daily vessels by late 2026 through Oman's coordinated traffic plan and limited mine clearance, but the combination of ongoing safety concerns, blockade restrictions, and incomplete mine removal prevents the 60 daily arrival threshold from being met before December 31.
Worst case
US-Iran conflict escalates further with additional attacks on commercial shipping, Iran maintains the strait closure indefinitely, mines remain uncleared, and the US blockade continues through December 2026, resulting in traffic remaining near zero with no recovery.
