Gold prices dropped 3.4% in a single session, marking an extreme decline not seen in nearly two decades. Statistical analysis indicates this move corresponds to a Z-score of -2.90, an event with only a 0.2% probability under normal distribution estimates that typically occurs once every two years. The sharp sell-off coincides with surging U.S. Treasury yields, which are creating significant volatility across the precious metals market. Since 2006, gold’s average daily change has been +0.05% with a standard deviation of 1.19%, highlighting the severity of today's deviation from historical norms.
