Mkhwebane was speaking at a news conference in Pretoria.
"The ratings agencies have been clear that the effectiveness of the central bank is one of the strongest pillars supporting this economy - a claim that speaks to both our price and financial stability mandates", Kganyago said.
She specifically asked for the removal from the constitution of the phrase "to protect the value of the currency" that has been central to South African monetary policy since the end of white-minority rule in 1994.
"This is quite unusual that a Public Protector has been so specific on changing the constitution or indeed be so radical on transformation", he said. She will be expected to answer questions based on the lack of State Capture findings thus far.
The Public Protector also found that Absa had "unduly benefited" from the bailout.
Public Protector Busisiwe Mkhwebane wants government to recover more than R1 billion in alleged misappropriated public funds awarded to Absa in a series of apartheid-era bailouts. Absa‚ which has not yet seen the report that contains the order‚ said it would study it before a possible legal review.
Absa denied any wrongdoing.
For remedial action, Mkhwebane has referred the matter to the Special Investigating Unit, which must in turn approach President Jacob Zuma to reopen the presidential proclamation R47 of 1998 "in order to recover the misappropriated public funds unlawfully given to ABSA Bank in the amount of R1.125 billion".
"Absa did not make a provision in its accounts for the repayment of the interest on the SARB loan to Bankorp because no such liability to repay interest existed", they said.
On Sunday, DA MP and justice spokesperson Glynnis Breytenbach said that with the flurry of reports uncovering state capture, it was more important than ever for the public protector to investigate and report without fear or favour.
