Quadruple witching, a significant event in the financial calendar, is causing heightened volatility as $7.1 trillion in derivatives expire today. This marks the largest expiration ever recorded, with $5 trillion tied to the S&P 500 index alone. The event, occurring quarterly, involves the simultaneous expiry of stock index futures, stock index options, single stock options, and single stock futures, leading to increased trading activity and price swings. Crypto markets are also feeling the impact, with Bitcoin currently trading at $69,800. Historical data suggests Bitcoin often experiences muted performance on quadruple witching days, followed by declines. Additionally, a separate $13.5 billion in crypto derivatives is set to expire on March 27, indicating continued market turbulence.
