Yemen’s Houthi movement has resumed attacks on commercial shipping in the Red Sea after announcing a maritime blockade on Saudi Arabia, prompting renewed diversions around the Cape of Good Hope. Peninsula said a typical Suezmax tanker on the diverted route would need about 1,500 mt of additional bunker fuel, adding around $800,000 in bunker costs and producing roughly 3,800 mt of extra CO2 emissions. The company also warned that ships transiting the Mediterranean must switch from standard VLSFO to 0.1% sulfur fuel under MedECA rules, increasing demand for compliant products.
