According to ENGINE's 13 November update, high-sulphur fuel oil in Rotterdam lost about twice as much value as very-low-sulphur fuel oil over two weeks, doubling the Hi5 spread since 30 October. Prompt supply in the ARA ports is tight, and buyers are advised to give suppliers 5-7 days of notice.
Durban prices also rose on the day, tracking a firmer Brent.
A wider Hi5 spread makes scrubber-fitted ships cheaper to fuel with high-sulphur oil, which shifts bunker demand and freight costs on the Europe leg. Tight prompt supply keeps bunker costs elevated for shipping grain and feed.
