CME Group is tightening the screws again—margin requirements on precious-metal futures just got hiked for the second time in a single week. The move comes after a pretty wild stretch in trading where prices spiked hard, then pulled back sharply. It's the kind of volatility that pushes exchanges to recalibrate risk controls. Whether you're trading commodities or crypto derivatives, this pattern of margin adjustments usually signals serious price swings and elevated leverage risks worth paying attention to.
