The discounts for high-sulphur fuel oil (HSFO) compared with IMO 2020-compliant fuels have gradually widened in the past month as vessel operators begin consuming the cleaner products.

Based on Ship & Bunker’s assess­ments of global average bunker prices, the discount of HSFO to 0.5% low-sulphur fuel oil (LSFO) increased from $141 per tonne on 7 October to nearly $161 in early November.
