Global financial markets are bracing for a historic quadruple witching event on Friday, March 20, 2026, with a record-breaking $7.1 trillion in notional derivatives exposure set to expire simultaneously. This quarterly event, where stock index futures, stock index options, single-stock options, and single-stock futures all expire, is expected to trigger a sharp surge in trading activity and potential price swings across asset classes, including cryptocurrencies.
According to Goldman Sachs, this expiry is the largest ever recorded, eclipsing all prior records. It includes roughly $5 trillion tied to the S&P 500 index and $880 billion linked to single stocks. The scale is immense, with the expiring options representing notional exposure equal to approximately 10.2% of the total market capitalization of the Russell 3000.
Cole Kennelly, CEO of Volmex Finance, warned that the event could spill into crypto markets, stating, "quadruple witching could trigger a spike in cross-asset volatility as large derivatives positions expire." The Bitcoin Volmex Implied Volatility index was already trending higher ahead of the event.
Historical data from 2025 shows a consistent pattern for Bitcoin on quadruple witching days: muted or flat performance on the day itself, followed by weakness in the subsequent days and weeks. For instance, in September 2025, Bitcoin fell over 1% on the witching day and then plunged from $177,000 to $108,000 in the following week.
Bitcoin dropped below the key $70,000 level on Thursday, struggling to hold support. Data indicates the current sell-off is being driven more by futures traders than spot buyers. While spot selling fell by around $40 million, selling in the perpetual futures market was far larger at $506.75 million, pointing to leveraged traders as the main force behind the decline. The broader market Fear and Greed Index sits at 30, firmly in 'fear' territory.
Looking ahead, the crypto market faces another volatility event with a separate $13.5 billion crypto derivatives expiry set for March 27 on Deribit. Positioning data suggests traders are bracing for continued turbulence rather than a strong directional recovery.
