Summary

US and Iranian strikes on ships in the Strait of Hormuz have led to a significant decline in maritime traffic in the area, with an average of only 10 commodity ships transiting the strait per day over the past 10 days, the lowest since May. The number of vessels passing through the strait has been declining since September 4, when it was more than 15, and is now down to as low as six on September 5. Data from analytics firm Kpler shows that only two vessels passed through the strait on September 5, mostly using the Iranian route. The strikes have escalated a "major maritime conflict" with commercial tankers being used as instruments of economic pressure, according to maritime intelligence firm Marisks.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
