South African currency is about the 16th most widely traded currency on a global scale, and the economy is at 32rd or 33rd place, Groepe said yesterday at a lunch in Johannesburg.
Traffic in the spot is roughly $ 4 billion a day, and total turnover is as high as $ 17 billion, he said.
"There is no doubt that rand is a proxy, because why would you have such a difference in currency turnover compared to the size of the economy," he said.
Often currency is moving along with what is happening with other EMs.

She also thinks about creating policies because it is a significant inflationary risk, according to the central bank.
Nineteen-year-old volatility in relation to the dollar has risen to 26 percent during the Turkish currency crisis in September, and the third is for that country alone in Libya and Argentinean weight, according to data collected by Bloomberg. Price movement has since fallen to 15.8 percent, though it is the third largest among peers in emerging markets.
South African currency is heading for its best results in November in 30 years, after winning 8.2 percent against the dollar. Nevertheless, this year, by 9.4%.
