History

Historical Context

During the July 1997 Asian financial crisis, Indonesia’s rupiah collapsed by roughly 83 % and the IMF pledged a $40 billion rescue, triggering political upheaval and market crashes. The memory of that volatility shapes today’s 2024 IDX-MSCI downgrade talks and UBS’s warning of $19 billion outflows, prompting regulators to lower daily circuit-breaker limits to 7 % through 2026.
