Indonesian Markets Plunge 9% as Updated Trading Halt Rules Take Effect

The stock exchange triggers a 30-minute pause and revises thresholds to address economic pressures after U.S. tariffs and record rupiah lows.

The Indonesian Stock Exchange activated a 30-minute trading halt after the main index dropped 9% on April 8, 2025, the first trading day since March 27.
Revised trading rules now trigger a pause at an 8% index drop, up from 5%, with subsequent halts at 15% and a full-day suspension at 20%.
The rupiah fell 1.8% to a record low of 16,850 per dollar, surpassing its Asian Financial Crisis trough.
The adjustments aim to stabilize the market and prevent panic selling as global economic pressures, including a 32% U.S. tariff on Indonesian goods, weigh on investor confidence.
Stock exchange officials emphasized the changes are temporary and designed to provide liquidity and calm during volatile conditions.
