"It is cost effective to sell fuel oil instead of putting it into the secondary refinery system when middle distillate product price is cheap," a trader said.

This year, bunker operations will be suspended from December 28 to January 3, market sources said.
"Dry bulk carriers have been taking bunkers for two trips in November, to avoid taking bunkers in December," a trader said.
"December demand is good, but still not as good as November," a second trader said.
