In his annual report released on Friday, Van Rooyen states: "Our responsibilities have grown to include supervising financial advisers and intermediaries, as well as running a newly established call centre."
In the period under review, the FSB has become a signatory to the International Organisation of Securities Commission's (Iosco) multilateral memorandum of understanding.
"This achievement reflects the FSB's compliance with international standards on the exchange of information and enforcement with foreign regulatory authorities in the interest of fair, efficient and transparent securities markets."
Van Rooyen was elected deputy chairperson of the Iosco executive committee at its annual conference in Istanbul, Turkey, in May last year.
