SINGAPORE- The cash premium for cargoes of 380-centistoke (cst) high-sulphur fuel oil (HSFO) in Singapore rose to a record on Tuesday, according to Reuters data, boosted by intense buying interest amid shrinking supplies.

The cash premium for 380-cst HSFO jumped to $30.88 per tonne to Singapore quotes on Tuesday, up from $23.09 a tonne in the previous session. 

The latest record exceeds the previous high of $24.31 per tonne on July 11, one of the first signs of the impact of a shift in global ship fuel rules set to occur in 2020.
