Conflicts in Yemen have brought ship traffic in Bab al-Mandeb to a standstill. The escalating conflict on Yemen's western coast has brought ship traffic in the Bab al-Mandeb Strait, one of the most sensitive points in global logistics, to a standstill, putting a vital maritime route at great risk. 10% of world maritime trade and 12% of global crude oil pass through here. The passage of oil and chemical tankers has decreased by 91%. Only 1 ship passed through in the last 24 hours, while total ship traffic decreased by 88% in 24 hours.

Windward is tracking 14 Saudi-flagged vessels rerouting around the Cape of Good Hope instead of transiting the Bab el-Mandeb Strait, as Houthi attacks on Saudi-linked shipping in the Red Sea continue. • • Since July 20, the diversions have added an estimated 140-195 extra vessel-days and $13-14M in voyage cost across the fleet, each transit running 10-14 days and roughly $0.9-1M longer than the direct route. • • The willingness to absorb this scale of delay and cost reflects how seriously Saudi Arabia is taking the Houthi threat, rather than a routine commercial routing choice. Given its outsized share of global shipping and energy trade, that risk aversion is a signal worth watching beyond the Saudi fleet for what it implies about trade flows through the Red Sea corridor. • • Live Red Sea and Bab el-Mandeb tracking:
Following the Houthi takeover of Perim Island and Yemen's southern Red Sea coast, AIS-transmitting traffic through the Bab el-Mandeb Strait has picked up. Satellite imagery from 08:01 UTC on September 14 confirms that no dark vessels were detected transiting at the time. • • Although seemingly counterintuitive, broadcasting AIS is how vessels signal they're not party to the conflict, claiming the free passage that still stands for non-Saudi vessels.
The UN warns of a phase threatening international trade: 7.4 million barrels of oil per day are at risk in the Bab el-Mandeb Strait, and Brent crude surpasses $105 as shipping declines.

Due to escalating conflicts and security risks on Yemen's western coast, commercial ship traffic through the Bab al-Mandeb Strait has fallen to critical levels. Before the crisis, an average of 70-75 ships passed through the strait daily; in the last 3 days, only 79 commercial ships have passed through. According to maritime tracking systems, 25 ships passed through the strait on September 8th, 28 on September 9th, and 26 on September 10th. News that the Houthis have taken control of the strategic Zukur Island and seized Mayyun Island in Bab al-Mandeb has increased tensions in the region. It is stated that the pressure on the strait, which is one of the critical transit points of the trade and energy line extending from Asia to Europe via the Suez Canal, could trigger a new rise in global oil prices.

BREAKING: Houthi forces have taken Perim Island. The Bab el-Mandeb is 20 km wide at that point. • • Mokha and the Hanish Islands fell on September 10. Perim fell this morning. Yemen's Red Sea coastline is now Houthi-held end to end, and the strait's narrowest point is under their control. • • Windward all-source operational intelligence, as of 1300 UTC September 11: • • Bab el-Mandeb transits unchanged so far. 17 inbound September 10, 13 by midday today. • • Outbound may be softening: 24 to 9 over the same windows (partial day, AIS-based). • • 16 tankers and 33 cargo vessels transmitting in the strait across 19 flags. • • Crude tankers in the Red Sea up 38% since the offensive began September 3 (78 vs. an expected 57). • • From Mokha, Dhubab and Perim, the lane is within artillery range. Enforcing a selective blockade just got cheaper. • • Windward's MIOC has issued a Special Report on the situation. • Read now:

In case of obvious data integrity issues (i.e., erroneous data), the market may remain open until the end of the third calendar day (ET) after the date on which such data is first released to allow for corrections. Data integrity issues refer only to clerical or other similar errors in the underlying data, and do not include cases where IMF Portwatch differs from alternative sources.
The resolution source for this market will be IMF Portwatch, specifically the transit calls data published for the Bab El-Mandeb Strait at https://portwatch.imf.org/pages/6b1814d64903461b98144a6cc25eb79c, both in the chart and through downloadable files. Where an unrounded and rounded value provided by the resolution source differ with respect to the resolution of this market, the unrounded value will be used.
