At 0638 GMT, the rand was trading at 8.6035 against the dollar, slightly softer than Friday's New York close of 8.59.

"There's probably more risk for rand weakness in the coming days. It does look like there are still concerns," said Ion de Vleeschauwer, a trader at Bidvest Bank.

US employment data on Friday suggested the euro zone's debt mess was taking its toll on the world's largest economy, stoking fears of a worldwide slowdown compounded by gloomy manufacturing data from China and Europe.

"Obviously those very weak US job figures on Friday have sparked rumours that there could be more quantitative easing, which should benefit emerging markets," De Vleeschauwer added.

Government bonds were largely unmoved. The yield on the three-year bond was flat at 6.355 percent while that on the 14 year paper gained 1.5 basis points to 8.93 percent.
