Cable has given up about half a cent in early trade, presently down at 1.5880. Risk sentiment has taken a bit of a knock, the market unnerved by soaring U.S. bond yields (10 yr treasuries up 19 bps yesterday.) The fear is that higher borrowing costs could seriously hinder U.S. economic recovery.
From here, technical supports for cable come at 1.5870 and then 1.5850/55.
