The London Metal Exchange, the world’s biggest metals marketplace, raised the fees it charges members and users to boost revenue as it invests in new products and systems. The average transaction fee, including trading and clearing, will climb 34 percent, the bourse said in a statement today. The exchange will increase annual subscription fees for members and introduce a one-off application fee. The LME Clear clearing house fee will be unchanged from previously published levels and charges on trades done on the bourse’s floor will have a “significant” discount. The new charges will be effective Jan. 1, it said. http://www.bloomberg.com/news/2014-09-29/lme-raise...
