Oil and gas producers BP and BG Group both reported a fall in third-quarter profits yesterday, in part due to the drop in the oil price. Crude has dropped 25 per cent since mid-June, amid surging supplies of shale oil from the US and a slowdown in global demand, particularly in China, the world's second-largest petroleum consumer. Some are predicting that it could fall even further. Goldman Sachs forecast on Sunday that oil would average $85 a barrel in the first quarter of 2015, down from an earlier forecast of $100. In late trade yesterday Brent, the international benchmark, was trading up 13 cents at $85.96 a barrel.
