By 04:59 UTC on October 20, the Jakarta Composite Index had rebounded by 3 percent, breaking a severe selloff. To improve free-float accuracy and avert a downgrade, the Indonesia Stock Exchange announced it will exclude 80 highly concentrated stocks from its primary index calculations. Regulators also introduced emergency transparency rules targeting closely held shares.

Under the new transparency mandates, companies are required to disclose any shareholder controlling 1 percent or more of outstanding equity. Amid these regulatory shifts, Bank Indonesia faces mounting pressure to raise interest rates to defend the currency if foreign capital flight resumes.

Prior to the rebound, by 07:52 UTC on October 19, Indonesian equities had fallen to their lowest valuations since 2020. Foreign institutional funds preemptively cleared their books to avoid being trapped in a less liquid, standalone market, a capital flight that threatened to weaken the rupiah and raise the cost of capital for major Indonesian conglomerates.

How the story developed

On October 16, index provider MSCI proposed downgrading Indonesia from an 'Emerging Market' to a 'Standalone Market', citing persistent opacity and suspected stock manipulation. A downgrade would force passive investment funds tracking MSCI's global benchmarks to systematically liquidate billions of dollars in Indonesian holdings.

The announcement triggered an 11.4 percent intraday plunge on the IDX Composite, marking the steepest one-day equity selloff since January 1998. Indonesian regulators argued they had already enacted transparency reforms, including a 15 percent free-float roadmap, and sought clarification on the decision.

On October 17, Indonesia's Financial Services Authority fined three listed companies, DSSA, BREN, and CUAN, a combined $117 million for market manipulation and concealing initial public offering share allocations. The enforcement targeted coordinated trading rings that artificially inflated share prices between 2023 and 2026.

Alongside the financial penalties, regulators suspended the licenses of the involved brokerage directors. Authorities also announced they are investigating 31 additional stocks for criminal violations as MSCI continued to weigh the downgrade over transparency concerns.
