       SINGAPORE, June 20 (Reuters) - Onshore fuel oil stockpiles at
key trading and storage hub Singapore built for a fourth straight
week, official data showed on Thursday.
    Inventories  rose 19% to 22.81 million barrels (3.59
million metric tons) in the week ended June 19, reaching a 17-week
high, Enterprise Singapore data showed. 
    Bunkering demand has been tepid in the week, while at the same,
broader supplies to Asia recovered, market sources said. 
    On the exports front, top destinations for fuel oil outflows from
Singapore's onshore tanks included China, Philippines and Bangladesh
in the week ended June 19. 
    Meanwhile, most of the inflows into onshore tanks hailed from
Russia and the United States in the same week, excluding cargo
movements between Singapore and Malaysia. 
    Amid higher inventories, spot premiums for the low-sulphur market
remained trapped between $1 to $2 a ton over Singapore quotes in
recent weeks. High-sulphur 380-cst premiums were also steady
week-on-week at $11 to $12 a ton. 
    Bunkering demand slowed in a holiday-thinned week, while some
shipowners also monitored the recent oil spill situation, said market
sources.
    Singapore premiums of delivered bunker fuel held at about $10 a
ton for the flagship 0.5% low-sulphur fuel grade, little changed
through the month, based on data from sources.   
    Meanwhile, incoming fuel oil supplies to Asia in June climbed
closer to May volumes, which were slightly above 5 million tons.
