Key Summary:

  • Bank Indonesia shifts policy priority to stabilize Rupiah
  • All monetary policy ammunitions have been exhausted
  • Capital flights are driven by fiscal & government distrust

Rupiah has reached a record low of 17,700/USD (-6% YTD) as the currency faces intensifying selling pressure driven by both global and country-specific factors, including:


Energy shock (oil prices >$100/barrel), MSCI index rebalancing that reduces country weight to around 0.5% (from 0.7%), surging import costs (oil, heavy equipment), and fiscal capacity constraints amid a spending surge (implied FY26 budget deficit/GDP >3%).
