Outgoing SA Reserve Bank Governor Gill Marcus is a remarkable leader, the Black Management Forum said on Monday.

"Her leadership is demonstrated by how she has managed to build an amazing pipeline of talent and a truly professional team. She is indeed a remarkable and attuned leader," the BMF said in a statement.

"When the history of this country is written, her name will loom large and the BMF wishes her all of the very best in her next phase of the struggle and her continued enormous contribution."

On Thursday, Marcus announced she would step down on November 8, at the end of her five-year term.

She made the announcement in Pretoria after a briefing on the monetary policy committee's repo rate decision.

"This is my last MPC," Marcus said at the time.

Marcus's stewardship of SARB and decisions taken by her and her team during critical times had yet to be fully appreciated, the forum said.

"In all our engagements and interfaces with her and her team, she was always accessible, in time, on point, effective and efficient," it said.

"The BMF also applauds her for all that she has done to increase transparency of the SARB."

On Thursday last week, President Jacob Zuma extended his gratitude to Marcus.

"We wish to thank the governor for her excellent service and leadership," Zuma said in a statement at the time.

"She has steered the bank during the difficult periods of the global economic and financial recession and ensured the achievement and maintenance of stability."

Zuma said government valued Marcus's contribution and wished her all the best in her future endeavours.

Zuma's office said he would announce the new governor in due course.
