The dollar fell 1.2 percent against the yen after the central bank cut its purchases of long-term government bonds earlier this week, putting the US currency on course for the biggest two-day decline in nearly eight months.

By 07:08 GMT the spot price of gold was up 0.9 percent at $ 1324.40 an ounce, having earlier touched its highest since September 15 at $ 1326.56 an ounce.
US gold futures for February delivery rose $ 11.50 an ounce to $ 1325.20 an ounce
