Banking supervision is an activity of the State Bank in collecting, synthesizing and analyzing information on subjects of banking supervision through the information and reporting system in order to prevent, detect, prevent and promptly handle risks causing unsafety to banking operations, violating regulations on safety of banking operations and other relevant laws. This article focus on the first 13 BCPs, which are about how countries should organize their national frameworks for banking supervision. These 13 BCPs establish requirements on supervisory powers and responsibility (BCP1-7) and supervisory process (BCP8-13). The writing also gives some examples (corresponding to some contents of BCPs) from the actual implementation in Vietnam - a typical developing country in south-east Asia and has been striving to apply international best practices for strengthening banking supervision.
