City analysts said further price rises are not inevitable. Jeremy Batstone, head of research at Natwest Stockbrokers, said the price of oil per barrel had been driven up by fears of an attack on Iraq, which could result in Iraqi oil coming off the market. 'The markets are fearful about a war,' he said. 'But I think it is jaw, jaw and not war, war at the moment - and, on that basis, I think it is not inconceivable that the oil price might fall back.'
