1413 ET - An interest rate increase by the Fed on September 16 is more likely than on October 28, Nuveen's Dan Close says. "You know, raising rates about a week before the election is tough," he says. August's jobs report was stronger than anticipated, boosting bets on a September hike. Close, who focuses on municipal bond markets, expects munis to move in tandem with Treasurys if the Fed moves. "It won't be as pronounced as the Treasury curve...we will likely move in sync if we do see a rate hike."
