One hundred days into Jeffrey Hendrik’s leadership at the Indonesia Stock Exchange (IDX), the stakes couldn’t be higher. With a looming extraordinary shareholder meeting on October 28, the exchange stands at a crossroads of reform and potential financial upheaval.
Goldman Sachs warns of potential outflows reaching $13 billion if Indonesia’s market status is downgraded. Meanwhile, MSCI has already highlighted the risk by wiping $370 billion from IDX’s stock value. The pressure is on for the new board to deliver tangible reforms, not just rhetoric.
IDX’s new board has been tasked with implementing a 15 percent free-float rule by end-2025, requiring 187 trillion rupiah in shares to be offered. This move is crucial for maintaining market credibility and attracting foreign investment. However, the real test lies in the upcoming shareholder meeting, where demutualization mechanics and ownership changes will be on the agenda.
MSCI has given Jakarta until November 2026 to demonstrate that these reforms are more than cosmetic. The clock is ticking, and the IDX must prove its commitment to transparency and market stability. As Jeffrey Hendrik aims to elevate IDX into the global top 10 exchanges, the road ahead is fraught with challenges but also ripe with opportunity.
The stakes are huge: Goldman Sachs estimated potential outflows of as much as $13 billion in a downgrade scenario, while Reuters said roughly $370 billion in stock value had already been wiped from IDX since MSCI’s January warning. ANTARA reported on September 22 that IDX will hold an extraordinary general meeting on October 28, 2026, after the issuance of OJK Regulation No.
Reuters said around 187 trillion rupiah, about $10 billion, worth of shares would need to be offered if all listed firms are to meet the 15 percent free-float rule, based on IDX assessments at end-2025. Indonesia Business Post reported on August 20 that IDX introduced a Price Impact Ratio methodology on July 15, 2026, as a new criterion for deciding which stocks fall into the High Shareholding Concentration bucket.
Beyond that, MSCI’s review runs into November 2026, after Reuters said the firm gave Jakarta five more months to prove the reforms are not cosmetic. Reuters reported on June 24 that MSCI deferred a decision on cutting Indonesia from emerging-market to frontier status until November 2026, saying the reforms were a “step in the right direction” but that “consistent implementation and sustained effects” were still needed.
The latest reporting makes clear that the new 2026–2030 IDX board is being judged less on rhetoric than on whether it can turn reform promises into measurable market fixes before November. 13 of 2026 on exchange shareholders, the rule underpinning demutualization.
Jeffrey Hendrik, approved as president director on June 29 in a shareholder meeting attended by 90 shareholders representing 100 percent of voting rights, said he wants IDX to enter the global top 10 exchanges by market capitalization or daily trading value; at the time, he said Indonesia ranked 19th and 17th on those measures. October 28, 2026 is the next hard date, when shareholders meet and may confront demutualization mechanics and possible new ownership entry if approvals are ready.
