Foreign Direct Investment (FDI) in Indonesia is regulated by a minimum investment requirement of IDR 10 billion. However, this policy is often considered burdensome, especially for small and medium investors. In addition, supervision of the implementation of this regulation by the competent authorities is still considered less than optimal, which results in the emergence of legal uncertainty and potential irregularities in its implementation. This research aims to analyse the FDI authorized capital policy in the form of a Limited Liability Company (PT) in accordance with the prevailing laws and regulations. The study also evaluates the implementation, supervision, and law enforcement conducted by relevant agencies in order to ensure compliance with the policy. As part of the analysis, the study conducts a comparison with FDI policies in other Southeast Asian countries, such as Singapore and Vietnam. These two countries were chosen because they have investment regulations that are considered more flexible and attractive to investors. The approach used in this research is normative juridical, relying on secondary data as the main source. The research findings are expected to provide strategic recommendations for FDI policy reform in Indonesia, so as to create a more competitive, highly competitive investment climate, and be able to attract more foreign investors to contribute to national economic development.
