While Brent crude prices pulled back from Monday's spike, prices remain firmly above $100 a barrel territory with Brent around $112.93 and US crude at approximately $104.

Back in the Gulf, Maersk confirmed its US-flagged container ship, Alliance Fairfax, departed the Persian Gulf through the Strait of Hormuz under US naval protection - underscoring the fraught security environment.
