Indonesia Stocks Fall as Much as 11.5% After MSCI Warning

Indonesia's stock market fell as much as 11.5%, its steepest one-day decline since 1998. MSCI raised concerns about suspicious trading, possible stock manipulation and limited transparency in the market.

The sell-off adds a sharp emerging-market stress signal for U.S. traders watching risk assets. The rupiah also weakened past 18,000 per U.S. dollar, extending pressure beyond equities.

This year's decline has topped 30%, and foreign investors have pulled nearly $5 billion. Those figures put the steep daily loss alongside broader declines and investor outflows.

The comparison with 1998 puts the one-day move in a longer market context. The reported year-to-date decline and foreign withdrawals show pressure extending beyond a single trading session. Alongside the stock drop, the rupiah's weakness adds another sign of strain across Indonesia's financial markets.

For U.S. risk-asset traders, the combination of a sharp equity decline, currency weakness and foreign outflows makes Indonesia a broader emerging-market stress signal.
