The number of vessels tracked passing through the Strait of Hormuz fell to a one-week low on Tuesday, as shipowners continued to avoid the strategic waterway amid disruptions linked to the conflict involving Iran and the US.

Separate data recorded 11 transits, down from 14 a day earlier.Before Iran closed the waterway following the start of US-Israeli attacks on February 28, around 130 to 140 vessels typically passed through the strait each day.

According to experts, India may find it difficult to quickly reduce its dependence on Russian crude even as the US moves closer to giving President Donald Trump powers to impose tariffs of up to 100% on countries buying Russian oil.

Experts said alternative supplies from Gulf countries, the US and Venezuela may not be sufficient to replace Russian volumes at the same scale, particularly when global energy markets are already facing disruptions.
