In recognition of the important role banks play in any economy, numerous researches have been undertaken on how these institutions should be regulated. For example research on capital requirements have indicated that the capital base of a bank is vital for the protection of its creditors (its deposirors) and hence for the maintenance of general confidence in its operations and the underpinning of its long term stability and growth.Other researches have addressed the deposit insurance schemes as well as reserve requirements and their effects on the risk taking behaviour of banks. The principle objective of this paper is to rcview the current literature on capital regulations with the intent of exploring the implications of banking theory for optimal regulation. Results suggest that there are mixed arguments about capital regulations and Its effects to banks risk taking behaviour. It is inconclusive as to whether or not risk based capital require­ments increases incentives for banks ro take risks
