**The Houthi assault on Saudi Arabia came as they failed to hit shipping and fewer than twenty vessels passed the Strait that week.**

The Houthis launched a military strike against Saudi Arabia on Saturday. The operation did not succeed in hitting any shipping targets. During the same period, fewer than twenty vessels moved through the Strait of Hormuz. The reduced traffic reflected the heightened risk in the region.

No vessels were reported damaged or sunk despite the offensive. The lack of successful attacks coincided with the week's low transit count through Hormuz.

During the week of October 12, fewer than twenty ships were recorded transiting the Strait of Hormuz. This figure represented a marked decline from typical weekly volumes. The count was confirmed on Monday.

The operation failed to achieve any successful hits on shipping. In the same week, under twenty vessels were recorded passing through the Strait of Hormuz.

## Analysis

While the strike demonstrates an escalation on land, the inability to affect maritime traffic suggests either limited capability in the naval domain or effective defensive measures by regional forces.

The drop to fewer than twenty vessels in the Strait of Hormuz signals heightened caution among commercial operators. Shipping companies may be rerouting vessels or delaying voyages to avoid potential threats, which could impact global oil flows and increase freight costs. However, the precise magnitude of these economic effects remains uncertain without data on alternative routes and price responses.

Future Houthi actions will likely be shaped by the perceived success of this dual-front approach. Conversely, continued failures at sea may limit their leverage, leaving regional security dynamics in a state of cautious monitoring.
