The U.S. 10-year Treasury note yield, which moves inversely to price, dipped further below 2 percent to 1.8560 percent — close to an April low — after closing at 1.966 percent on Monday.
Meanwhile, the longer-dated 30-year bond yield was also lower at 2.6702 percent after finishing at 2.781 percent in the previous session.
