What happened — and what it teaches
In the sweltering summer of 1998, Indonesia's financial system was on the brink of collapse. The Jakarta Composite Index—Indonesia's flagship equity market—was navigating one of the most turbulent periods in its history. Bank failures, currency depreciation, and sovereign default fears created a toxic environment where investor capital evaporated overnight. The period from July 1998 to February 1999 represented a critical stress test for anyone holding Indonesian equities.
The index descended from 463.87 to 400.55, a decline of -13.7% over 144 trading days. Yet the headline figure masks the true violence of the moves: a maximum drawdown of 47.4% erased nearly half the market's value at its trough, while the largest single session surge or drop reached 10.7%. Participants faced 25 decision points, nine of them critical moments requiring immediate strategic adjustments.
This replay teaches the brutal mathematics of crisis management. Holding through a 47.4% drawdown requires either extraordinary conviction or ruinous position sizing. The 10.7% single-bar volatility exposes the inadequacy of normal risk models during panic. Nine critical junctures force learners to confront the psychological toll of consecutive loss decisions, where every choice carries the weight of protecting simulated capital from further erosion.
