This document discusses the impacts of establishing the Indonesian Financial Services Authority (OJK) on Indonesia's central bank. It notes that previously, different institutions regulated different types of financial institutions, which caused weak oversight. The OJK now regulates all financial institutions. Its establishment impacted various aspects of banks and non-bank financial institutions. It also shifted regulatory and supervisory tasks from Bank Indonesia to the OJK. There is a debate around whether oversight should be consolidated or separated, and the document discusses arguments on both sides regarding maintaining monetary stability and preventing conflicts of interest.
