The rand was up 0.6 percent at 8.09 to the dollar by 0640 GMT, compared to an 8.1550 close in the New York market on Monday. The unit is approaching its 100-day exponential moving average, having blasted through the 50-day average - another important level - at the end of last week.

After that, charts suggest the currency will be looking at 8.05.

"Given the rand's support at 8.20 a breach of 8.05 would signal that the rand bulls are finding further traction," said Judy Padayachee, a technical strategist at Absa Capital.

"My previous recommendation had been to short the rand at 8.20 but if the rand goes below 8.05 then that short recommendation is no longer in place. Such a breakout would then open up the 7.70 level."

Dealers say more positive news out of the euro region would be needed to push the rand through the psychologically key 8 rand level.
