**Iran kept control of Kharg Island and Bab el-Mandeb traffic stayed below normal levels.**

In September 2026, maritime traffic through the Strait of Hormuz did not return to normal, and the Bab el-Mandeb Strait similarly failed to normalize. The Iranian regime remained in power throughout the month. Iranian authorities also retained control of Kharg Island.

Vessels navigating the Hormuz corridor continued to experience reduced throughput, with many opting for longer alternative routes. The sustained disruption kept oil and gas shipments below pre-crisis volumes. Shipping companies reported persistent scheduling challenges.

The Bab el-Mandeb Strait, while not fully closed, saw traffic levels remain below typical volumes. Maritime operators cited lingering security concerns as a factor in the shortfall. No full reopening was recorded by the end of the month.

The Iranian government showed no signs of collapse during September, maintaining its administrative structures and policy direction. Domestic stability allowed Iran to continue its maritime and regional activities.

Control of Kharg Island stayed under Iranian authority through September, with no transfer of ownership reported. The Island's strategic position in the Persian Gulf remained leveraged by Tehran. Its status contributed to the broader continuity of Iran's maritime posture.

## Analysis

The continued abnormal flow through the Hormuz and Bab el-Mandeb corridors means that global oil transport faces ongoing bottlenecks, potentially sustaining higher freight rates and price volatility. The lack of normalization also limits the capacity for rapid response to regional supply shocks.

Iran's retention of Kharg Island and the survival of its regime reinforce its ability to project power in the Persian Gulf. Control of the Island secures a logistical hub for Iranian naval and commercial vessels, while regime stability ensures consistent policy implementation. These factors together sustain Iran's leverage over regional maritime traffic.

Future developments remain uncertain; any shift in the security environment could alter the status of the chokepoints. Diplomatic initiatives or escalations could either reopen the straits to normal levels or deepen disruptions. Stakeholders must therefore monitor regional dynamics closely, as the situation could evolve rapidly.
