Rupiah Is the Worst Performing Currency in ASEAN, Here's Why

Key Summary:
- IDR has consistently weakened over the past 20 years
- Domestic and global risks have led to substantial outflows
- Policy uncertainty undermines rupiah's stability and credibility
In the past one year, the Indonesian rupiah (IDR) has been the worst-performing currency among major ASEAN economies, depreciating by -6.3% against USD.
Even though the weakness in IDR is not entirely unique, particularly after the US trade war policy in Apr-25, several domestic issues have driven investors to sell the rupiah and move toward more stable currencies.
