The dollar, on Monday, January 30, edged by 0.5 percent to a 10-day high against a basket of currencies, reversing earlier falls.

On Monday the DXY fell to 100.17 but has reversed course to trade up 0.4 per cent on the day to 100.97.

Meanwhile, the British pound has also relinquished gains, now off 0.4 per cent to $1.2498.
