Jakarta stocks suffer worst crash since 1998 after MSCI downgrade warning

Indonesia's Jakarta Composite Index crashed 11.57% on Oct. 16 to close at 5,185.10, its worst single-day fall since the 1998 Asian financial crisis, after the sell-off opened with an 8% drop that triggered a 30-minute circuit-breaker halt. The rout wiped out roughly US$60 billion in market value and spilled into Oct. 17 reporting worldwide. The trigger was a warning from index provider MSCI Inc. that it is launching a consultation on reclassifying Indonesia from 'emerging' to 'standalone' market status, bypassing frontier status in what analysts called an unprecedented double downgrade. MSCI cited opaque shareholding structures, suspected coordinated trading and weak enforcement. The consultation period runs through April 30, 2027, with a final decision expected before June 30. Indonesia currently makes up about 0.4% of the MSCI Emerging Markets Index. UBS estimates a downgrade could cause up to US$19 billion of foreign outflows; Mirae Asset Sekuritas sees around US$3 billion in passive outflows and Citigroup projects mid-single-digit billions. President Prabowo Subianto's government faces scrutiny over governance, central-bank independence and state control of industry; regulators have announced reforms including wider ownership disclosures and higher minimum free-float rules.
