Indonesian conglomerate stocks faced sharp sell-offs Monday as MSCI and FTSE Russell announced plans to exclude or reclassify several major companies from their global indices, triggering market corrections and liquidity concerns. The moves—part of routine index reviews—highlight ongoing scrutiny over corporate governance, ownership concentration, and market transparency in Indonesia’s equity markets.

MSCI Removes Six Firms, FTSE Russell Preps Further Cuts

MSCI Inc. Removed six Indonesian companies from its flagship indices, while FTSE Russell separately announced it would exclude stocks with highly concentrated ownership from its benchmarks by June 2026. The actions sent the Jakarta Composite Index (IHSG) tumbling nearly 2% in intraday trading, with shares of affected conglomerates—including Barito Renewables Energy, Amman Mineral Internasional, and subsidiaries of the Sinar Mas Group—plummeting.

The MSCI decision follows its May 13 index review, during which the firm excluded six firms from its broader Indonesian index and 13 additional stocks from its small-cap benchmark. The removals were framed as part of MSCI’s ongoing efforts to align its indices with global best practices for liquidity, free-float standards, and governance transparency.

FTSE Russell’s upcoming changes, set to take effect June 22, target stocks where ownership concentration exceeds thresholds that could impair index replication. The provider cited “market feedback indicating deteriorating liquidity” for affected stocks, warning that investors tracking the index might face challenges divesting without undue market impact.

Conglomerate Stocks Lead the Sell-Off

Among the hardest-hit stocks were:

• PT Barito Renewables Energy (BRE): A subsidiary of the Sinar Mas Group, BRE’s shares dropped over 5% amid reports of concentrated ownership structures. The company, a major player in pulp and paper, has faced scrutiny over its corporate governance practices.
• PT Amman Mineral Internasional (AMMN): A mining conglomerate linked to the Amman Group, its shares fell nearly 4% as investors reassessed its inclusion in global benchmarks. Analysts noted that Amman’s diversified holdings—spanning minerals, energy, and infrastructure—could complicate free-float calculations.
• PT Petrindo Jaya Kreasi (HSC): A construction and property firm, HSC’s shares declined after MSCI’s review flagged potential governance risks tied to its parent company’s ownership structure.
• Subsidiaries of Grup Sinar Mas: Multiple listed entities under the conglomerate, including pulp and paper units, saw sharp declines as MSCI’s exclusion process tightened eligibility criteria.

Traders and portfolio managers cited “momentum-driven corrections” following the announcements, with some describing the sell-off as a “technical rejection” rather than a fundamental reassessment. However, long-term investors warned that the exclusions could signal deeper concerns about Indonesia’s capital market reforms.

Market Reactions and Regulatory Context

The IHSG’s decline came as MSCI and FTSE Russell’s actions reinforced broader trends in emerging-market indices. MSCI’s 2026 report highlighted growing demand from limited partners for “enhanced data transparency” and “improved valuations” in private and public markets alike. The firm’s acquisitions, such as its purchase of PM Insights for objective pricing data, reflect a shift toward stricter benchmarks.

Indonesian regulators have acknowledged the challenges, with the Financial Services Authority (OJK) previously emphasizing reforms to increase free-float shares and reduce ownership concentration. However, FTSE Russell postponed a full index re-ranking until September, citing “ongoing market developments.”

“The exclusions are not a reflection of company performance but rather a response to structural risks,” said a Jakarta-based portfolio manager who manages funds tracking MSCI indices. “Investors are now recalibrating exposures, which has led to short-term volatility.”

What Comes Next

MSCI’s next index review is scheduled for September 2026, when it may reconsider additions or reclassifications based on governance improvements. FTSE Russell’s June 22 changes will remove affected stocks at a price of zero to maintain index integrity, a move that could pressure liquidity for smaller-cap conglomerates.

Analysts expect the IHSG to remain volatile in the near term, with potential support around the 7,300 level—a threshold mentioned in recent trading commentary. However, the longer-term impact hinges on whether Indonesia accelerates reforms to meet global index providers’ standards.

For now, the sell-off serves as a reminder of how closely Indonesian equities are tied to the decisions of MSCI and FTSE Russell—a dynamic that has reshaped capital flows across emerging markets in recent years.
