According to The Kobeissi Letter, $6.8 trillion worth of options on stock indexes, ETFs, equity index futures, and individual stocks are set to expire today, marking potentially the largest 'triple witching' options expiration on record (source: @KobeissiLetter, June 20, 2025). Traders should prepare for significant market volatility, as this convergence of expiries can trigger sharp moves in traditional markets, which historically have spillover effects on the cryptocurrency sector, including BTC and ETH. Heightened volatility in equities often leads to increased risk-off behavior or liquidity events, impacting crypto trading volumes and price action.
