0820 ET - The FOMC minutes will be closely examined as investors try to glean clues on the thinking of policymakers when they raised rates last month. BMO's Ian Lyngen says a common theme among investors before the Fed meeting was that Chairman Warsh needed to hike to maintain credibility, and not directly as a result of recent data. "The degree to which a similar 'credibility hike' framework was discussed on the Committee will be notable and imply that the forward path of hikes will be more gradual, consistent with the latest Williams comments," Lyngen says. He adds that he'll also watch for how the FOMC is viewing the balance of risks to its dual mandate, which may provide insight on its appetite to continue hiking "or whether the market could be justified in viewing September's move as truly a one-off hike."
