TEMPO.CO, Jakarta - Jeffrey Hendrik, Director of Development at the Indonesia Stock Exchange (IDX), stated that all data requested by Morgan Stanley Capital International (MSCI) will be made public. This data includes the ownership structure of shares under 5 percent.
Jeffrey stated that this data will be accessible on the IDX's official website. The implementation of this more comprehensive data disclosure will begin this February.
"For shares under 5 percent that will be disclosed to the public, we will also request confirmation from the relevant issuer as to whether they are affiliated or not," Jeffrey told reporters at the Indonesia Stock Exchange on Sunday, February 1, 2026.
Furthermore, the IDX and the Indonesian Central Securities Depository (KSEI) will also improve the classification of investor types with greater detail. This will be done by adding investor classifications as requested by MSCI.
KSEI President Director Samsul Hidayat stated that the Indonesian capital market currently uses nine investor types based on the Single Investor Identification (SID). The nine investor types are individual (ID), corporate (CP), mutual fund (MF), financial institution (IB), insurance (IS), securities company (ISC), pension fund (PF), foundation (FD), and others (OT).
Samsul stated that these nine investor types will be further subdivided into 15 subtypes, specifically for the corporate (CP) and others (OT) categories.
"Now, these nine existing types for corporate and others will be further subdivided into 15 types. So, there will be 15 types of others, but the SID will not change. The SID will remain the same, but there will be additional fields, such as the corporate nature, and then what are the others," Samsul said during a dialogue with capital market players at the IDX on Sunday, February 1, 2026.
In its announcement, MSCI stated that investors are concerned about the transparency of Indonesia's share ownership structure. "Although there have been minor improvements to the float data of the Indonesia Stock Exchange, investors have highlighted that fundamental issues related to investability persist due to a lack of transparency in share ownership structures and concerns about the possibility of coordinated trading behavior that undermines proper price formation," MSCI said in its statement. its announcement, quoted on Wednesday, January 28, 2026.
To address these concerns, MSCI stated that more detailed and reliable information on share ownership structure—including monitoring high share ownership concentration—is needed to support its assessment of the free float and investability of all Indonesian stocks. Therefore, MSCI has taken action in the form of a temporary freeze on share adjustments.
