Will fewer than 170 ships transit the Bab el-Mandeb Strait between September 14-September 20?

Analysis

The clearest signal comes from the daily tally itself: vessel crossings through the Bab el-Mandeb Strait have hovered in a narrow band of 21 to 24 ships a day through the week of September 14-17, according to preliminary ship-tracking data cited in shipping reports. That range sits right at the edge of what a sub-170 weekly total requires, since a seven-day period needs to average under roughly 24.3 transits a day to stay beneath the threshold. The pattern is consistent, not volatile. Reports show 24 vessels on September 14, 22 the next day, then a slight easing to 21 by September 17, alongside similar single-digit declines in Strait of Hormuz traffic reported over the same days. That steady, slightly downward drift, rather than any sharp swing, is what gives the forecast its lean toward the lower count holding. Context reinforces the trend rather than contradicting it. Broader Suez Canal data, described as reported rather than confirmed, shows transits still running at roughly half pre-crisis levels even as isolated signs of recovery emerge, such as a COSCO-affiliated container ship making its first southbound run through the canal since Red Sea tensions began. That kind of selective return suggests operators remain cautious rather than resuming full volume, which supports continued suppressed daily crossings. The single biggest variable to watch is whether daily counts tick back up toward 25 or higher in the final days before the window closes, since even a modest rebound could push the weekly total past 170.
