Jakarta Composite Index Closes at 8,122 as Market Reform Signals Lift Confidence

JAKARTA, Investortrust.id — The Jakarta Composite Index closed sharply higher at 8,122 on Tuesday, Feb 3, 2026 in Jakarta as investors responded positively to clearer details of Indonesia’s capital market reform agenda, including new transparency measures demanded by global index providers. The rebound signaled renewed confidence after regulators outlined steps to address ownership disclosure, liquidity, and data quality concerns that had weighed on sentiment.

The benchmark index ended the session up 199.87 points, or 2.52%, reversing an intraday slump that had briefly dragged it below 7,800. Turnover reached about Rp 28 trillion, equal to roughly $1.7 billion, reflecting broad based buying across sectors.

Liza Camelia Suryanata, head of research at Kiwoom Sekuritas Indonesia, said transparency was the core requirement for restoring foreign inflows. "For global investors, ownership transparency and reliable market data are a basic prerequisite," she said. "The essence of being a listed company is readiness to provide adequate and credible disclosure."

She added that liquidity was equally critical, particularly for passive funds that require sufficient market depth to allocate capital on a sustained basis. "Foreign investors still play a significant role because Indonesia’s market size is relatively small compared with global peers," Liza said.

By comparison, she noted that the market capitalization of Nvidia alone was equivalent to roughly six to seven times the total capitalization of Indonesia’s stock market. That imbalance, she warned, meant downgrades by global banks such as Nomura, following earlier moves by Goldman Sachs and UBS, could significantly narrow Indonesia’s investment pool.

The rally was driven by gains across all sectors, led by basic materials, industrials, energy, technology, and transport stocks, while conglomerate linked names again dominated trading. Shares tied to major business groups including Prajogo Pangestu, Astra, Medco, Sinar Mas, Bakrie, and several mining and energy groups posted sharp advances, underscoring the benchmark’s sensitivity to large capitalization stocks.

Alongside price action, attention turned to additional reform steps announced by the Financial Services Authority, which plans to expand investor classification from nine main categories to 27 more granular sub types. The move is designed to provide a clearer picture of who owns Indonesian equities and to meet data requirements from MSCI and other global index providers.

Hasan Fawzi, a member of the OJK board and acting head of capital markets supervision, said the current system managed by Indonesia’s central securities depository was too limited. "Previously there were nine main groups, starting from individuals, securities companies, mutual funds, and so on, up to a broad others category," he said.

Under the new framework, investor types will be broken down into more specific segments, including private equity, venture capital, government entities, sovereign wealth funds, brokerage firms, private banks, state owned enterprises, public companies, cooperatives, political parties, educational institutions, international organizations, central banks, religious institutions, and other specialized entities.

Hasan said OJK would also publish recap data on investor classifications and provide the information directly to MSCI. "We will provide a recap of investor classifications to the public and to MSCI, for example how many investors are affiliated or indicated as affiliated," he said.

He added that the richer dataset would help index providers assess eligibility more accurately. "They need sufficient information to consider whether a stock should be included or not, such as how many shareholders are part of the board of directors or board of commissioners," Hasan said.

Finance Minister Purbaya Yudhi Sadewa sought to calm markets, describing the recent selloff as a temporary shock rather than a structural failure. "This is not a market meltdown, it is just a shock," he said at the Indonesia Economic Summit 2026. "Once investors realize I am still serving as finance minister, the market will recover strongly, as we saw today."

Purbaya said MSCI’s warning over potential index reclassification should be viewed as an opportunity to improve market practices. "Concerns about a downgrade are unnecessary as long as we follow up on MSCI’s recommendations," he said. "We will adopt global best practices and ensure that investment in Indonesia remains safe."
