JOHANNESBURG - Investors are watching the Rand ahead of a decision by the US Federal Reserve.
Earlier, the Rand reached a three-week low as the dollar strengthened ahead of the decision by America's central bank.
The Federal Reserve is likely to leave interest rates unchanged on Wednesday.

Higher interest rates in the US make dollar investments more attractive, and the dollar has been strengthening in recent days.
If the Fed hikes rates, it will impact the Rand negatively and could force the SA Reserve Bank to follow suit when it meets next month.
The European Central Bank, Bank of Japan and Bank of Canada are also due to announce their rate decisions this week.
