TankerMap takeaway
The latest complete UTC day in TankerMap shows 0 tanker transits through Bab el-Mandeb on 2026-07-27, down 100% versus the preceding 7-day average. The linked Suez Canal series also weakened sharply, with 1 tanker transit on 2026-07-27, or 88% below its preceding 7-day average. Read together, the chart points to an acute contraction in tanker movement along the Red Sea corridor at the end of the period, rather than a stable low-flow pattern.
What changed
The supplied reporting says Yemen's Houthi movement is seeking to mirror Iran's use of chokepoint pressure, this time around Bab el-Mandeb in the Red Sea. TankerMap evidence shows traffic had already become patchy before the latest reading, but the final point is especially weak. Bab el-Mandeb daily tanker counts moved between low single digits and brief spikes earlier in the month, then faded: 0 on July 23, 0 on July 24, 0 on July 25, 1 on July 26, and 0 on July 27. The moving average also fell to 1.1 vessels by the latest complete day, indicating sustained deterioration rather than a one-day anomaly. Suez follows the same direction of travel, dropping from 13 on July 23 to 8, 9, 5, and then 1 by July 27.
Why it matters
Bab el-Mandeb and Suez are sequential gateways for many tanker voyages between the Red Sea and the Mediterranean. When Bab el-Mandeb transits hit zero, it suggests owners or charterers may be avoiding the southern entrance altogether, which then feeds into weaker Suez tanker counts. That matters because the corridor is a major routing option for crude and refined products. In the Bab el-Mandeb series, the latest zero is not driven by LNG, which is absent on the latest day, and crude has also fallen away to 0. The Suez reading is similarly notable because the latest day includes 0 crude tankers and 0 product tankers, with the single transit coming from LNG. The immediate implication is not proof of a full closure, but a visible loss of tanker confidence in the route.
Uncertainty
The chart shows counts, not causes. TankerMap confirms that flows collapsed on the latest complete UTC day, but it does not by itself prove whether the decline reflects direct attacks, precautionary rerouting, scheduling noise, port delays, or temporary convoy timing. Daily chokepoint counts can be volatile at low levels, and Bab el-Mandeb had several zero days earlier in the month as well. The source report describes Houthi intent and strategic signaling, yet the data here only confirms that tanker traffic is currently very weak through the corridor.
What would confirm or refute
Confirmation would come from several more complete UTC days with Bab el-Mandeb near zero or at zero, continued depressed Suez tanker counts, and especially a prolonged absence of crude transits in both series. A rebound would weaken the case for a sustained disruption: if Bab el-Mandeb returns toward its earlier low-single-digit norm and Suez recovers toward its prior mid-to-high single-digit range, the latest point would look more like an extreme short-term trough than a durable step-change.
