IDX Outlines Transparency Push After MSCI Freezes Indonesia Stock Review

JAKARTA, Investortrust.id — The Indonesia Stock Exchange said on Wednesday, Jan 28, 2026 in Jakarta that it would intensify engagement with MSCI after the index provider froze its review of Indonesia’s equity market, a decision that triggered a sharp selloff in the Jakarta Composite Index and raised concerns over market classification risks. The exchange said it would work with regulators and market infrastructure institutions to address transparency issues flagged by MSCI, a move aimed at stabilizing investor confidence and safeguarding Indonesia’s standing in global benchmarks.

The exchange said it would continue discussions with the Financial Services Authority and the Indonesian Central Securities Depository to improve the disclosure of shareholder data following MSCI’s announcement of temporary measures affecting Indonesia’s inclusion in its Global Standard Indexes. MSCI had earlier said concerns over ownership transparency and potential coordinated trading remained unresolved, prompting it to suspend several index review changes.

Market reaction was swift, with the Jakarta Composite Index opening down as much as 6.8 percent to 8,369.48 before paring losses to around 5.25 percent by 09.40 a.m. local time. Selling pressure was broad-based, with decliners far outnumbering gainers in early trade.

IDX Corporate Secretary Kautsar Primadi Nurahmad said authorities would maintain open communication with MSCI to resolve the issue. “Previously, we had improved disclosure by publishing free float data on the IDX website, but if MSCI considers this insufficient, we will continue discussions on data transparency in line with MSCI’s proposal to reach a mutual agreement,” Kautsar said.

MSCI announced on Tuesday, Jan 27, 2026 that it would apply temporary treatment to Indonesia by freezing increases in the Foreign Inclusion Factor and Number of Shares, halting the addition of new constituents to MSCI Investable Market Indexes, and suspending size-segment upgrades, including moves from Small Cap to Standard. The decision also covered the February 2026 index review cycle.

According to MSCI, the measures were intended to reduce index turnover and mitigate investability risks while giving market authorities time to enhance transparency standards. The index provider said it had been consulting market participants since October 2025 on the potential use of monthly holding composition reports published by KSEI as an additional reference for assessing free float.

MSCI said feedback from investors showed persistent concerns over the reliability of ownership data, particularly regarding the classification of shareholders and the risk of coordinated trading that could distort price formation. “Investors continue to highlight limited transparency in ownership structures and concerns over potential coordinated trading, which could undermine fair price discovery,” MSCI said in its statement.

The index provider stressed that more detailed and reliable ownership information, including monitoring of high ownership concentration, was needed to strengthen assessments of free float and market investability. It added that progress would be closely monitored in the coming months.

MSCI warned that if meaningful improvements were not achieved by May 2026, it would reassess Indonesia’s market accessibility status. Such a review could result in a reduced weighting in MSCI Emerging Markets indexes or even a potential reclassification from Emerging Market to Frontier Market.

Market analysts said the announcement added to near-term pressure on equities. “The MSCI decision has the potential to exert additional pressure on the index in the short to medium term, as the absence of index upgrades limits passive fund inflows that are crucial for large-cap stocks,” said Hendra Wardana, founder of Republik Investor.

From a technical perspective, Wardana said the index was likely to trade within a volatile range. “The current pressure is largely technical and sentiment-driven and does not reflect a deterioration in domestic economic fundamentals,” he said, adding that fundamentally solid and liquid stocks with relatively transparent ownership structures could attract selective investor interest while markets await clearer policy direction.
