According to CoinMeta, market fluctuations triggered by the Federal Reserve's interest rate decision led to about 90,000 traders experiencing margin calls, resulting in a total loss of $280 million. The severe volatility caused by this decision reflects the market's extreme sensitivity to adjustments in interest rate paths. The large-scale margin call events have exposed the significant risks associated with high-leverage trading at points of policy shifts. This phenomenon indicates that market risk appetite is undergoing a sharp contraction, and investors are forced to re-evaluate the logic behind asset pricing.
