The Financial Services Board (FSB) was the government of South Africa's financial regulatory agency responsible for the non-banking financial services industry in South Africa from 1990 to 2018. It was an independent body which had a mandate to supervise and regulate the non-bank financial services industry in the public interest. This included the regulation of the biggest stock exchange in Africa the Johannesburg Stock Exchange. From 1 April 2018 the FSB was split into prudential and market conduct regulators.
