Benchmark oil contract Brent North Sea hit its highest level since late 2014 on Thursday, breaching US$ 80 per barrel, with some market players predicting it could rise all the way to US$ 100. Higher oil prices, in turn, pushed the shares of energy firms in European stock markets higher, helping London's FTSE to set a new all-time high, and the Paris CAC to establish a fresh 2018 peak.
