Producers including Shell affected by price war between Saudi Arabia and Russia
Oil prices have rallied after a call between Donald Trump and Vladimir Putin raised hopes that tensions between Moscow and Saudi Arabia may start to ease.
Brent crude prices rose as much as 3.5% to $23.55 overnight, after hitting an 18-year low of less than $23 per barrel on Monday. The global benchmark for oil prices lost some of its gains later on Tuesday, but was still trading just above the $23 level at $23.01, a rise of 1.1%.
