Around 15% of the world's shipping traffic passes through the territorial waters.
Houthis attacked an Israel-affiliated container ship in the Red Sea not far from Arden according to a UKMTO report.
When the Israel-Hamas conflict in Gaza comes to an end, as it must eventually do, the Houthis might seize the opportunity to withdraw from holding the world to ransom.

Houthis ordered American and British humanitarian workers to leave Yemen, many fear that the action will exacerbate the country's crisis, already once described by the UN as the world's worst.
Yemen's Houthis said on Tuesday they could only reconsider their missile and drone attacks on international shipping in the Red Sea once Israel ends its "aggression" in the Gaza Strip.
Asked if they would halt the attacks if a ceasefire deal is reached, Houthi spokesman said the situation would be reassessed if the siege of Gaza ended and humanitarian aid entered.
