Summary

Analysts say the threat to oil tankers in the Middle East is at its worst since the Iran war began, with attacks on vessels in the Red Sea and Strait of Hormuz causing a significant reduction in ships passing through these key routes. The number of ships passing through the Strait of Hormuz has dropped from over 100 per day before the war to just 8-11 per day, according to ship-tracking firm Kpler. Matthew Wright, an analyst at Kpler, warns that the situation is "stacked on top of a problem" with both the Strait of Hormuz and the Red Sea waterway facing threats from Iran-backed militias in Yemen and the Houthi fighters. The reduction in oil tanker traffic has resulted in only about 4 per day passing through the Bab el-Mandeb strait, carrying crude oil to Asia.

Why this leaning score
The article's framing and word choice are generally neutral, but there is a subtle emphasis on the negative consequences for oil trade, which may be perceived as sympathetic to the interests of those involved in that industry. Phrases such as 'worst since start of Iran war' and 'constraining oil flows' could be seen as slightly weighted towards emphasizing the disruptions caused by the conflict.
Written under an earlier scoring contract, which gave a paragraph rather than checkable quotes. Re-analysing this article replaces it.

Peter Sand, chief analyst at Xeneta, another ship-tracking company, said the fighting had taken the shipping industry "back to to square one" and that things were in "a terrible state, regardless of which shipping type you're you're looking at". "The alternatives for getting cargo, whether that's hydrocarbons or container shipping, are really not great… it is really still troubling times with no clarity and no change of fortunes within sight."

Iran → come → Hormuz

they → go → detection
For much of the war, some ships carrying oil from Saudi Arabia had instead passed through an alternative shipping lane in the Red Sea, between the kingdom and northeast Africa. asserted
ships → carry → kingdom
But a recent spate of attacks by Yemen's Houthi fighters on Saudi tankers using the alternative waterway has further heightened the risks. asserted
spate → use → risks

they → pass → detection
Not all vessels are deterred from passing through because the Houthi threat is only targeted at Saudi shipping, with the total number sitting at about 50% of pre-attack levels. asserted
number → deter → levels

Its foreign ministry ministry spokesman Esmaeil Baqaei said any agreement would not lift the current restrictions while US "aggression" continued. asserted
aggression → say → restrictions
Kpler's Wright said that while talks with Oman could be productive, any deal would need the involvement of the US and the fear is that current negotiations could be a "false start" without concessions on at least one side.
