Traders said the month-on-month fall is largely due to the shorter numbers of days in February, and the drop in the number of vessels arriving in Singapore.
The number of vessel arrivals stood at 9,981 or 145,450 million GT, down about 9.2 per cent from a month ago.
Reflecting the steady bunker demand in February, the bunker premium, or price between ex-wharf bunker prices and fuel oil cargo values, had stayed in positive territory since end-December.
