What happened — and what it teaches
The Straits Times Index in 1998 provides a stark classroom for understanding how global financial shocks propagate across markets. Over 146 daily bars spanning from May 14 to December 7, 1998, the index moved through one of the most turbulent periods of the Asian Financial Crisis. The Russian sovereign default sent ripples across emerging markets worldwide, and Singapore's benchmark was not immune. With 25 decision points embedded across the replay — 9 deemed critical — participants faced a relentless test of their policy frameworks and risk assumptions. The stage was set for a study in volatility, where every entry, exit, and sizing decision carried amplified consequences.
The numbers reveal the depth of the challenge. The index closed the period at 1376.82, having started at 1301.78 — a nominal gain of 5.8%. Yet this headline figure obscures the turmoil within. The maximum drawdown reached 39.1%, meaning portfolios could have been eroded by more than a third before recovering. The largest single-bar move of 9.3% underscores the violent intraday swings that could have stopped out positions or triggered margin calls. A participant navigating this period needed to survive extreme drawdowns while capturing the eventual recovery — a difficult needle to thread without disciplined process.
This replay teaches that survival during systemic stress requires more than accurate directional calls. It demands position sizing that absorbs 39.1% drawdowns without forcing liquidation, conviction to hold through single sessions that swing 9.3%, and the emotional discipline to avoid policy abandonment at market lows. The 9 critical decision points act as pressure valves where pre-commitment to rules separates skilled execution from reactive panic. For trainees, the 1998 Straits Times Index is not a story of profit — it is a story of process, risk calibration, and psychological resilience under conditions where every assumption is challenged.
