The dollar index, which gauges the greenback against a basket of six currencies, last traded lower at 85.32 after touching its lowest in four sessions.

On the other hand, the dollar rose as high as 7.3824 crowns, its highest since September 2010. It last traded at 7.3277 crowns, up 0.4 percent on the day.
