Islamic money market transactions require consistency between contractual requirements, operational regulation, and institutional supervision. This study examines how these elements are connected in Indonesia, focusing on the regulatory framework established in 2024. It employs normative legal research with statutory and conceptual approaches. Primary materials comprise DSN-MUI Fatwas No. 37/2002 and No. 78/2010, Bank Indonesia Regulation No. 6/2024, Board of Governors Regulation No. 20/2024, and Financial Services Authority Regulation No. 2/2024 and Circular Letter No. 15/SEOJK.03/2024. Relevant scholarly publications provide supporting materials. The analysis maps transaction requirements, supervisory responsibilities, documentary evidence, and corrective mechanisms. The findings identify three interrelated dimensions of compliance: conformity of contractual substance, fulfilment of transaction procedures, and institutional accountability. Detailed requirements for SIMA, SiKA, and SiPA demonstrate that compliance must be assessed through the underlying assets, commodity ownership, investment mandates, and transaction records. Bank Indonesia supervises money market participants, while the Financial Services Authority regulates sharia governance within Islamic commercial banks and Islamic banking units, involving sharia supervisory boards and internal control functions. Accordingly, the principal analytical issue concerns the traceability of requirements across these supervisory arrangements. The study proposes a document-based mapping of compliance responsibilities to support consistent examination and corrective action. Its conclusions concern regulatory design and do not establish the actual compliance rate or effectiveness of supervision.
