The Monetary Policy Committee is due to make its announcement this afternoon.
Yesterday consumer price inflation for the month of April came in at 6.2 percent, which is above the inflation target band of between three and six percent.
Standard Bank economist Thandi Sithole says the Central Bank has already raised rates by 75 basis points.
“We think the recent hike is enough to keep inflation anchored towards the target and the bank needs to be more inspective of growth and rising unemployment.”
Sithole adds rates could be kept on hold.
