Yemen’s Iran-aligned Houthi militia has announced a naval blockade, but vessel traffic through the Bab el-Mandeb Strait continued despite the declaration. Early shipping activity suggested that the waterway remained open in practice even as the threat raised fresh concerns for maritime security.

According to MarineTraffic animations cited in the report, ships were still moving through the strait from Monday evening into Tuesday morning. That indicates the blockade announcement had not yet stopped transits, at least during the initial period after it was declared.

The report also pointed to market-based expectations around the risk of disruption, noting a 47.5% “YES” reading on successful Houthi targeting of shipping by July 31. That figure reflects continuing uncertainty over whether the group can translate its warning into a broader impact on commercial traffic.

For now, the gap between the Houthis’ stated blockade and the continued movement of vessels leaves the Bab el-Mandeb Strait open. Shipping operators and markets are likely to keep watching closely for any sign that the situation shifts from rhetoric to a more direct threat on the water.
