Global markets are bracing for heightened volatility as the quarterly derivatives event known as quadruple witching occurs on Friday. This event, which sees the simultaneous expiration of stock index futures, stock index options, single-stock options, and single-stock futures, often leads to increased trading activity and price swings. In March 2025, approximately $4.7 trillion in derivatives expired, marking the highest S&P 500 trading volume of the year. The current market environment is already volatile, with the VIX index recently surpassing 35, indicating significant market stress. Bitcoin, which often mirrors broader market movements, could experience increased volatility as well. Cole Kennelly, CEO of Volmex Finance, noted that the Bitcoin Volmex Implied Volatility Index is trending higher, suggesting potential cross-asset volatility spikes. Additionally, crypto traders are eyeing a major crypto derivatives expiry on March 27, with $13.5 billion set to expire on Deribit, further contributing to potential market fluctuations.
