Black Swan Events

If there is one thing traditional macroeconomic forecasting models hate, it’s a surprise. Most standard economic models are built on historical data and normal distributions—they assume tomorrow will look roughly like a minor variation of yesterday. But economic history is actually driven by the extreme outliers. We call these "Black Swan" events.

Coined by former trader Nassim Nicholas Taleb, a Black Swan is an event so rare and unpredictable that it sits entirely outside the realm of standard forecasting. Yet, when it hits, it causes catastrophic, systemic disruption. Crucially, human bias dictates that we rationalise these events in hindsight, inventing narratives to convince ourselves they were completely predictable all along.
