The Russian rouble dropped to its weakest against the euro since late May on Tuesday, hurt by relatively low oil prices and the prospect of lower export revenue due to the price cap on Russian oil which came into force this month. By 0732 GMT, the rouble had lost 0.9% to trade at 66.94 versus the euro, its weakest since May 30. It eased 0.8% against the dollar to 63.31 and had shed 0.9% against the yuan to 9.07.
