What happened — and what it teaches
The Jakarta Composite Index entered May 1998 at the epicenter of the Asian financial crisis, a period when regional markets faced cascading pressures from currency collapses and banking system failures. Indonesia, already grappling with domestic political turmoil, found itself increasingly exposed to spillover effects from Russia's August 1998 sovereign default—a distant event that amplified existing vulnerabilities across emerging markets. The period from May 12 to December 7, 1998, captured 146 trading sessions in which investors navigated extreme uncertainty, with contagion dynamics that tested conviction and discipline.
Over this span, the index closed at 399.46, representing a net decline of -7.2% from the opening level of 430.53. Yet the headline figure obscures the journey: a maximum drawdown of 47.4% occurred along the way, with the largest single-day move reaching 10.7%. Participants faced whipsaw price action where sharp rallies and capitulation-style selloffs alternated without clear trends, creating an environment where prediction proved treacherous and positional management determined survival.
This replay offers decision training centered on volatility absorption and emotional regulation. Trainees confront 25 decision points—9 deemed critical—forcing choices about position sizing, timing, and conviction under drawdown stress. The scenario illuminates how contagion events create non-fundamental price action, teaching the distinction between process-driven decision-making and reactive panic. Learning objectives include calibrating risk appetite to tail scenarios and recognizing that navigating 47.4% drawdowns requires both institutional discipline and psychological resilience rarely tested in normal markets.
