SINGAPORE, May 2 (Reuters) - Asia's spot differential for high sulphur fuel oil (HSFO) slumped into discounts on Friday, despite recent strength in refining cracks.

The market in Asia remains amply supplied, with plentiful cargo availability from the Middle East and Russia, trade sources said.

Singapore cash differential for 380-cst HSFO traded into discounts on Friday for loading dates in the second half of May, after recovering into short-lived premiums for just over a week.

Intermonth spreads also weakened sharply, trading into contango for both 180-cst and 380-cst HSFO grades for the prompt balance-May/June contract.

However, HSFO cracks retained strength for the prompt June contract after hitting their highest value in more than six years during the previous session. FO380BRTCKMc1

As for very low sulphur fuel oil (VLSFO), cash differentials have been extending recovery in recent days, with the product trading higher in the spot market, while prompt cracks LFO05SGBRTCMc1 remained above premiums of $10 a barrel.
