REUTERS/Andrew Kelly/File Photo Acquire Licensing RightsLONDON, Nov 7 (Reuters) - Europe has nowhere to hide from U.S. plans to mandate clearing of U.S. Treasuries transactions that will need to be carefully introduced over time, a global derivatives industry body said on Tuesday. A clearing house is backed by a default fund, ensuring that a transaction is completed even if one side of a transaction goes bust. Regulators began mandating the use of clearing more widely in derivatives markets after the global financial crisis in 2008 to improve stability and transparency. "It's something that you need to look at carefully and at this stage I think we still have more questions than answers as to how the actual process of clearing Treasury cash and Treasury repo will play out," Litvack said. Much will hinge on the details in the final rules that determine who will be within scope, O'Malia said.
