This offense fallsunder the category of white collar crime, characterized by complex and oftenundetectable modus operandi. This research aims to analyze the legal policiesgoverning the evidentiary process of insider trading in Indonesia's capital market,as well as to identify the obstacles encountered in proving such offenses. This study adopts a normative legal research method, employing statutory and case studyapproaches. The findings indicate that the prohibition of insider trading wasinitially introduced through Minister of Finance Decree No. 1548/KMK/013/1990,and later reinforced by Law No. 8 of 1995 concerning the Capital Market (UUPM).The UUPM regulates the enforcement of insider trading provisions throughadministrative, civil, and criminal channels. Proof of insider trading is pursued bydetecting the involvement of insiders conducting transactions based on materialnon-public information, and examining parties suspected of committing the offense.However, several obstacles to proving insider trading remain, including thecomplexity of the modus operandi, the lack of criminal history among offenders,and the difficulty of quantifying and proving actual losses before the court. Thestudy concludes that, although the legal framework for proving insider trading inIndonesia is in place, its enforcement remains significantly hindered. Therefore, itis necessary to strengthen investigative mechanisms and inter-agency coordinationto enhance accountability in the capital market.
