The rand weakened against the dollar in early trade on Thursday, as investors awaited the outcome of a central bank monetary policy meeting later in the day.
At 0725 GMT, the rand traded at R17.19 against the dollar, 0.22% weaker than its previous close.
The South African Reserve Bank (Sarb) will announce its repo rate decision at around 1300 GMT.
A Reuters poll published last week predicted the bank would raise its benchmark interest rate by 50 basis points to 5.25% as it tries to rein in inflation.
On Wednesday, data showed headline consumer inflation quickened more than forecast to 7.4% year on year in June, versus analysts’ predictions for 7.2% and a reading of 6.5% in May.
“Monetary tightening by the Sarb will primarily be aimed at anchoring inflation expectations and keeping up with the global wave of monetary tightening to avoid a further rand blowout and financial market instability,” ETM Analytics said in a research note.
On the stock market, the Top-40 and the broader all-share indexes opened slightly lower.
The government’s benchmark 2030 bond was weaker in early deals, with the yield up 3.5 bps at 10.985%.
