Singapore bunker prices were stable to lower on Tuesday but their premium to fuel oil cargoes were quoted higher, traders said. Prices for 380-centistoke (cst) bunker fuel were pegged at $335-336 a tonne, slightly lower than Monday's Asian close. But its differential to fuel oil rose to $7 a tonne from $4 on Monday.
Traders attributed the higher premiums to a berth congestions. A trader was seen delaying its fuel oil cargo shipment, after making heavy sales for June and July supply.
