The minimum regulated capital in the banking sector and its sufficiency has always been a matter on the agenda of the regulatory authorities, as it serves as a buffer or guarantee of the security of depositors' resources. The local methodology for calculating these indicators, mainly deriving from the BASEL I agreement, has been somehow overtaken by the development of complex financial instruments by the world banking system, which was once again demonstrated by the economical and financial global crisis since 2008. In this context, the implementation of the provisions of the BASEL III agreement is already a necessity because banking sector capitalization depends not only on the security of the Bank's creditors, but also on the economic stability of a country or region. The implementation of the BASEL III agreement, from the author point of view, will positively influence the supervision and regulation of the domestic banking sector not only through the fact that BASEL III takes into account several risks of the banking activity, but also the fact that the requirements for the capital of banks can be set as a whole on the banking sector and individually for each bank, which makes the surveillance process more risk-oriented.
