The rand was 0.32 percent weaker at 8.2670 against the dollar at 0623 GMT from New York's Monday close of 8.24. Lower trading volumes are expected on Tuesday after a national public holiday in South Africa.

"With poor global data and renewed concerns about Europe, EUR/USD is starting to slide again," Rand Merchant Bank said in a note. "The trend is now downwards, placing some mild upside pressure on USD/ZAR."

A drop in German business sentiment to its lowest since early 2010 stoked concerns about a slowdown in the euro zone's largest economy, despite the European Central Bank's recently announced bond-buying plan.

Spain also remained in focus as its government bond yields rose on concerns Madrid is dragging its feet in requesting the international bailout that most market participants expect.

The yield on South Africa's three year bond declined six basis points to 5.33 percent and that on the longer dated 14-year paper shedding eight basis points to 7.39 percent.

Treasury is due to auction on Tuesday 2.1 billion rand ($254 million) in total of its 2023, 2026 and 2048 government bonds at 0900 GMT.

"Demand is once again expected to remain robust with activity generally picking up around auctions," Rand Merchant Bank added.
