To state the obvious, "prudential supervisors can't be everywhere," APRA chief Wayne Byres told a regulators' conference yesterday. "APRA has a touch under 600 institutions - banks, insurers and pension funds - to supervise, and a little over 600 staff to do it. "Of that complement, only about 300 of the staff are directly involved in frontline supervision."In the case of banking, we have around 135 frontline supervisors covering 143 authorised deposit-takers - a ratio of just under one frontline supervisor per bank. Those organisations collectively employ over a quarter of a million staff and have aggregate assets of more than A$4.7 trillion. "These figures and ratios will differ in each jurisdiction represented in the room today, but one basic fact will not: supervisors have a lot to watch over."?
