The Fed is widely expected to raise interest rates by 25 basis points when it concludes a two-day meeting on Wednesday. Markets will be sensitive to the language used by the Fed to give an indication of its future interest rate plans, DailyFX analyst Warren Venketas told Reuters. "A dovish slant to the decision could see (the dollar-rand exchange rate) back around 18.00 while any inclination or openness to remain aggressive could open up the 18.50 resistance handle once more," he added.
The risk-sensitive rand often takes cues from global factors like U.S. monetary policy in the absence of major local drivers. The South African Reserve Bank will release its interest rate decision later this month.
On Thursday, local investors will turn their attention to S&P Global's Purchasing Managers' Index (PMI) for April for clues on the health of the South African economy.
