The rand opened stronger on Tuesday, tracking the dollar which fell ahead of US Federal Reserve Chair Jerome Powell's congressional hearing later in the day.

At 0715 GMT, the rand traded at 15.6600 against the dollar, 0.1 percent stronger than its previous close. The dollar was down around 0.1 percent against a basket of currencies.
The rand has tended to track global factors in recent sessions in the absence of major domestic drivers and is highly sensitive to shifts in sentiment towards emerging markets.
Around 1100 GMT, Statistics South Africa will release November manufacturing data.
Government bonds were slightly weaker in early deals, with the yield on the 2030 instrument rising 1.5 basis points to 9.500 percent. The Johannesburg Stock Exchange opened firmer, with the top 40 index up 0.66 percent.
