Indonesia's stock exchange is moving to shore up investor confidence after MSCI, the global index provider, warned the country could be downgraded to “standalone” market status — a call that helped trigger the sharpest two-day selloff in the market's history. In response, the exchange announced a series of measures aimed at making the market more transparent and easier to trade.
The changes include faster investigations into suspected price manipulation, the addition of independent observers to a committee that flags stocks with highly concentrated ownership, and the removal of such stocks from Jakarta's main index starting November 2nd. Regulators also extended a policy allowing companies to buy back shares without full shareholder approval until June 2027, a move designed to keep liquidity support in place.
Why MSCI's warning matters
MSCI's classifications are closely watched by global investors because they determine whether a market can be included in widely used benchmark indices. A downgrade to “standalone” status would make it harder for large, index-tracking funds to invest in Indonesian stocks, potentially reducing foreign capital flows.
The warning came amid concerns about market integrity and liquidity, particularly around stocks where a small number of shareholders control a large portion of the float. Such tightly held shares can be prone to sharp price swings and manipulation, which undermines the confidence of institutional investors.
By acting quickly, the exchange is signaling that it takes these concerns seriously. The new measures are designed to address the specific issues MSCI raised, particularly around price manipulation and the tradability of the benchmark index.
What the new measures mean
Starting November 2nd, stocks with highly concentrated ownership will be excluded from Jakarta's main index. This is a significant change because index inclusion often brings automatic demand from funds that track the benchmark. Removing these names could reduce their liquidity in the short term, as benchmark-tracking money moves elsewhere.
For investors, the trade-off is clear: the index becomes more representative of the broader market's tradability, but the excluded stocks may see wider bid-ask spreads and fewer daily trades. That could make them less attractive to foreign allocators who prioritize ease of entry and exit.
The exchange also said it will open investigations immediately when it spots potential price manipulation, rather than starting with warnings. This faster enforcement is intended to deter bad actors and reassure investors that the market is being policed effectively.
What it means for investors
For everyday investors, the key takeaway is that Indonesia is trying to keep its market attractive to global capital. The November 2nd deadline is now a focus for foreign index-linked flows, as fund managers adjust their portfolios to reflect the new index composition.
Investors who hold Indonesian stocks should watch for any announcements about which specific stocks will be removed from the index. Those names could see short-term selling pressure, while the broader market may benefit from improved sentiment if MSCI decides to keep Indonesia at its current status.
The extension of the share buyback policy until June 2027 is another supportive measure. It gives companies more flexibility to support their own share prices, which can help stabilize markets during periods of volatility.
While these steps are positive, the ultimate test will be whether MSCI sees enough improvement to avoid a downgrade. The exchange's willingness to act quickly is a good sign, but sustained progress on market integrity will be needed to win back full confidence.
For now, investors should keep an eye on how the index changes are implemented and whether the faster manipulation probes lead to any high-profile cases. The coming weeks will be telling for Indonesia's standing in the global investment community.
