Indonesia's stock market is in freefall. The Jakarta Composite Index has plunged roughly 37% from its 2026 peak, making it the worst-performing major global equity index, according to Bloomberg.
The Indonesian rupiah has weakened more than 7% against the US dollar, briefly trading above 17,700 per USD-an all-time low. Global investors aren't just trimming positions. They're heading for the exits.
The sell-off began in late January 2026, when MSCI flagged potential downgrades of Indonesian equities due to ownership concentration and low free-float issues. That single warning triggered an 8% decline, erasing approximately $80 billion in market value in a matter of days. Six companies were subsequently removed from the MSCI index during a January rebalance, forcing selling by emerging market funds.
March and May brought additional volatility, driven by further index rebalancing pressures and rising oil prices. Indonesia is a net oil importer, so higher crude costs widened the trade deficit, increased fiscal pressure on fuel subsidies, and weakened the rupiah further.
The result is a 'Sell Indonesia' environment. Foreign investors have withdrawn billions from both Indonesian stocks and bonds, with outflows showing few signs of slowing.
Concerns about President Prabowo Subianto’s governance and the transparency of Indonesia’s financial markets have been central to the investor exodus. The CEO of the Indonesia Stock Exchange resigned following the January crash. Leaders at OJK, Indonesia’s financial services authority, also stepped down. Authorities have since pledged governance reforms.
Indonesia is the fourth most populous country on Earth and Southeast Asia’s largest economy. A weaker rupiah makes foreign-denominated debt more expensive for Indonesian companies and the government, increasing default risk. As foreign capital exits, trading volumes thin out, making price moves more volatile and exits more costly for remaining investors.
