**Bab el-Mandeb Strait was not effectively closed and the United States had not announced an end to the Iranian blockade.**

On Wednesday 30 September, reports confirmed that traffic through the Strait of Hormuz had not returned to normal. The same period saw the Bab el-Mandeb Strait remain open, contrary to earlier expectations of an effective closure. Additionally, the United States had not issued a statement ending the Iranian blockade by the end of September.

Vessels continued to encounter delays and rerouting around the Persian Gulf. Shipping companies reported increased fuel consumption and longer transit times. Authorities monitoring the corridor noted that the disruption persisted despite diplomatic overtures.

The Bab el-Mandeb Strait stayed operational, allowing commercial ships to pass without the anticipated shutdown. Regional navies maintained patrols but did not enforce a closure. The lack of an effective blockage suggested that the threat level had not escalated to the point of sealing the waterway.

The United States did not declare the Iranian blockade lifted by the September deadline. The absence of an announcement left the blockade's status ambiguous for international traders.

## Analysis

The continued disruption in the Strait of Hormuz indicates that regional maritime tensions have not eased. Because a significant portion of global oil passes through the Strait, persistent delays can affect shipping costs and supply chain planning. However, without data on volume changes, the exact economic impact remains unclear.

The fact that the Bab el-Mandeb Strait remained open reduces the immediate risk of a major chokepoint shutdown in the Red Sea corridor. Nevertheless, the presence of naval patrols shows that authorities are prepared for potential escalation. Traders must therefore monitor the situation for any sudden policy shift.

The United States' failure to announce an end to the Iranian blockade keeps diplomatic uncertainty high. This silence may limit the ability of regional actors to negotiate a de-escalation, and it leaves commercial operators without clear guidance.
