1337 GMT - The easing of energy prices is having little impact on the dollar as expectations for further Federal Reserve interest-rate rises support the currency, ActivTrades analyst Ricardo Evangelista says in a note. The Fed's rate rise last week, along with signals of further tightening from Fed officials, has strengthened expectations that borrowing costs could rise again before year-end, he says. Currency traders will closely follow upcoming U.S. economic data and comments from Fed officials for further clues on the path of monetary policy, he says. The DXY dollar index trades flat at 100.472, having reached a seven-week high of 100.667 earlier.
