Spot gold briefly surged to $5,100, leading to a crisis at Shenzhen-based firm Shui Bei Jie Wo Rui. The company, which operated an online platform for non-physical gold trading, faced a liquidity crunch as rapid gold price increases prompted a wave of customer withdrawals. The firm was unable to fulfill all redemption requests, resulting in significant unrest. Over the weekend, hundreds of investors gathered at the company's physical location, prompting police intervention to maintain order. The total amount involved in the crisis has not yet been disclosed.
