Still, some industry sources viewed fuel oil cracks as elevated at current levels given the recent rise in crude oil prices to their highest since mid-2015, as well as ample inventory levels in Singapore and northwest Europe.

Meanwhile, lower supplier offers and a limited buying interest for 380-cst fuel oil cargoes weighed on cash premiums of the fuel, snapping three straight sessions of gains.
