**The strike began on Oct. 30 while Strait of Hormuz traffic stayed disrupted.**

Saudi Arabia launched a military operation in Yemen on October 30. The move arrived amid warnings of possible disruptions to regional shipping and airspace. By the end of October, none of the anticipated closures materialised.

Traffic through the Strait of Hormuz remained below pre-crisis levels, contradicting expectations of a return to normal by October 31. The Bab el-Mandeb Strait also stayed open, with no effective closure recorded. Shipping lanes therefore continued to operate under heightened alert.

The Houthis did not advance into Aden before the deadline, leaving the city under its existing administration. Perim Island remained under Houthi control, thwarting predictions of a change in possession. These outcomes kept the strategic balance in the southern Red Sea unchanged.

Saudi Arabian airspace stayed open throughout October, allowing commercial flights to continue without interruption. Israeli airspace likewise remained accessible, with no closure reported. The absence of airspace restrictions eased concerns for airlines operating in the region.

Overall, the only confirmed shift was the Saudi-Yemen military engagement, while the broader set of expected disruptions failed to occur. The situation left regional trade and travel largely functional despite the conflict.

## Analysis

By striking in October, Saudi forces may aim to weaken Houthi capabilities or pressure them into negotiations, though the precise objectives remain unclear.

Houthis' inability to enter Aden and the retention of Perim Island preserve the status quo in key strategic locations. Without gaining these footholds, the rebels lack leverage over the internationally recognised Yemeni government, limiting any immediate shift in the balance of power.

Future developments remain uncertain. While the Saudi strike demonstrates a new level of involvement, the absence of broader closures suggests that regional actors may be avoiding further escalation. Continued monitoring will be needed to see whether the conflict spreads to affect airspace or maritime routes in the coming weeks.
