Rosneft, Russia's state-owned oil company, is set to place 400 billion rubles ($6.1 billion) worth of bonds to finance "the company's projects and production plan", according to the firm. But there are fears that the deal could set off another ruble rout. In setting up the deal the company felt compelled to clarify that it would not use the money it raises in the bond sale for the "purchase of foreign currencies".
