Shareholding information in the capital market becomes more transparent

Samsul Hidayat, President Director of PT Kustodian Sentral Efek Indonesia (KSEI), said Indonesia’s capital market is entering a new phase of disclosure of shareholding information. The change takes effect after the trading session closed on Tuesday, 3 March 2026. It follows the implementation of public data provision provisions in accordance with the OJK Board of Commissioners Decision No. 1 of 2021.

‘After the market closes this evening, the Indonesian capital market will enter a new phase in terms of disclosures,’ Samsul said at the offices of the Indonesia Stock Exchange (IDX) in South Jakarta on Tuesday, 3 March 2026.

In the regulation, he said, the OJK designated KSEI and the Indonesia Stock Exchange (IDX) as providers of public data. One of the stipulations is the provision of share ownership data for issuers with holdings above 1 percent.

Samsul explained that as the custodian and settlement institution, KSEI maintains a centralised data on share ownership in scriptless form. Meanwhile, share ownership data in certificated form is obtained from the Securities Administration Bureau (BAE). In accordance with OJK directions, the data presentation format combines ownership in both script and scriptless forms.

He said that the data have been prepared and will be submitted to IDX and OJK today for publication on the OJK’s official website. Accordingly, whereas the Exchange previously disclosed holdings above 5 percent, the information now covers shareholders above 1 percent.

Additionally, KSEI has updated investor type data to be more detailed. Together with market participants, the data update has reached 97 percent for the corporate and others (others) category, and 93 percent of all institutional investors overall.

Samsul noted that the data will be presented based on the end-March 2026 position and is targeted to be available in early April 2026, in line with the commitments already set.
