But Mboweni is not your typical finance minister. He is a maverick who ordinarily would have been deemed too independent and outspoken to be a finance minister.
His independence was shaped by his decade-long stint as Governor of the Reserve Bank. In terms of our Constitution, the central bank must act independently and without fear, favour or prejudice - something Mboweni took most seriously.
He asserted his independence early in his Budget speech when he pointed out what he was presenting was in the best interests of our people and country, not the narrow objectives of any political party.
It was a big statement to make three months before a general election, but he was true to his word.
