A dramatic turnaround has unfolded in Indonesia's stock market, which has surged from a five-year low hit last month to officially enter a bull market. This shift is driven by valuation corrections, rapid regulatory intervention, and a gradual return of foreign capital.
The Jakarta Composite Index is still down approximately 29% year-to-date, but according to LSEG data, it has rebounded more than 10% from its early June low, meeting the threshold for a bull market.
Weeks ago, S&P Global confirmed Indonesia's BBB sovereign credit rating with a stable outlook, further boosting market sentiment. Mohit Mirpuri, a senior partner at SGMC Capital, stated, "S&P's confirmation removed a major macro uncertainty. Over the past month, the market's pricing logic has shifted from reflecting fundamental deterioration to reflecting a stabilization of corporate fundamentals."
This rally holds significant meaning for investors, as Indonesia's market had been under severe pressure from governance controversies and foreign capital outflows, with market confidence hitting rock bottom. Now, with multiple positive factors converging, a substantial shift in sentiment has occurred, providing a window for emerging market investors to reassess Indonesian assets.
MSCI's downgrade deferral curbs panic selling
Indonesia's stock market was in turmoil for most of 2026, triggered by index compiler MSCI questioning the corporate governance of several Indonesian stocks and considering downgrading the market from emerging market to frontier market status. Structural issues like low free float ratios and high ownership concentration have long been core concerns for MSCI.
According to a CNBC report, Gareth Leather, senior economist at Capital Economics, said MSCI's decision to defer the downgrade was a "huge relief" for investors, effectively curbing panic selling. Concurrently, some investors began taking profits from overvalued AI and tech stocks to reallocate capital to more attractively priced markets.
Value trap becomes value opportunity, foreign interest rekindled
As share prices fell, the valuation appeal of Indonesian stocks grew increasingly apparent. Liza Camelia, research head at Kiwoom Sekuritas Indonesia, told CNBC, "After months of massive selling, Indonesian stocks have become too cheap to ignore."
Positive signals on the fiscal front also injected confidence. Camelia noted that strong government tax revenue in the first half of the year, exceeding expectations, eased previously feared fiscal risks, with the reality proving better than the pessimistic outlook.
Proactive measures from Indonesia's financial regulators also provided crucial support for the rebound. Initiatives such as raising minimum free float requirements and strengthening equity disclosure rules directly addressed core market concerns about liquidity and transparency.
Jeemin Bang, deputy economist at Moody's Analytics, stated that these measures help "address the market's liquidity weaknesses and the resulting transparency and ownership concentration issues, which had previously driven some investors away." The regulator's swift response has, to some extent, restored basic trust in Indonesia's capital market institutional environment.
