0527 GMT - The prospect of the Federal Reserve following through on Chairman Kevin Warsh's hawkish message at Jackson Hole at the September meeting, together with the potential for further Treasury interventions, makes it challenging to hold long-end steepeners outright over the next few weeks, Deutsche Bank strategists say in a note. Longer term and more structurally, however, the strategists continue to favor higher term premia and steepener expressions, they say. These views are "based on negative underlying fundamentals and our view that meaningful fiscal consolidation remains unlikely," they say.
