What happened — and what it teaches

In December 2014, the EUR/CHF foreign exchange market entered a precarious phase. The Swiss National Bank had defended a 1.20 floor against the euro for years, making the franc's peg a cornerstone of monetary policy credibility. For traders and risk managers, this era represented a tension between the apparent stability of a managed exchange rate and the hidden risks of one-sided positioning. The period from December 2014 through May 2015 would test whether that stability was real or illusory.

The data span of 110 daily bars from 2014-12-08 to 2015-05-07 tells a dramatic story. The pair moved from 1.2027 to 1.0364, a decline of -13.8%. The maximum drawdown reached 18.6%, and the largest single-bar move hit an extraordinary 17.2% when the floor was abandoned. Across these months, participants faced 19 decision points, with 7 deemed critical for navigating the volatility.

This replay teaches that policy commitments carry tail risks that standard models underestimate. The decision training here focuses on process: recognizing when consensus positioning becomes vulnerable, maintaining discipline during gap events, and managing psychology when a once-stable market erupts. The 2010s vintage of this crisis reminds us that central bank credibility is not permanent, and that risk management must account for regime shifts rather than assuming continuity.
