The event represents the concurrent expiration of multiple derivative instruments: equity index futures, equity index options, individual stock options, and individual stock futures. QUADRUPLE WITCHING ARRIVES TOMORROW. $4.7 TRILLION in derivatives expires.What it means → 4 types of derivatives expire simultaneously. Trillions in positions get closed or rolled.Why it matters → Volume surges. Prices can swing hard, especially in the final hour of…— Manpreet Kailon (@preetkailon) March 19, 2026The magnitude of this financial event is substantial. During March 2025, approximately $4.7 trillion in equity and index derivative contracts reached expiration within a single trading session. That particular day registered the year’s peak S&P 500 trading volume, based on TradeStation data.Statistics for the March 2026 expiration remain unreleased at this time.Throughout these occurrences, financial institutions must simultaneously close out, extend, or finalize their positions. Market activity typically surges, with price volatility intensifying, particularly during the closing trading hour.Cole Kennelly, CEO of Volmex Finance, indicated the phenomenon might impact cryptocurrency markets. He stated “quadruple witching could trigger a spike in cross-asset volatility as large derivatives positions expire,” noting that the Bitcoin Volmex Implied Volatility index had already been climbing ahead of the event.Bitcoin’s Historical Performance During Witching EventsExamining 2025 data, Bitcoin’s price action during actual witching days remained largely subdued. More significant declines emerged during subsequent days and weeks.During March 21, 2025, Bitcoin experienced modest intraday losses but subsequently reached a bottom around $76,000 following market reactions to President Trump’s “Liberation Day” tariff announcements. On June 20, the cryptocurrency declined 1.5% before hitting a temporary low near $98,000 within two days.September 19 saw Bitcoin fall over 1% initially, then plummet from $177,000 down to $108,000 throughout the subsequent week. December 19 witnessed approximately 3% gains to $85,000, though the broader downward trend persisted.The recurring theme remains clear: limited volatility during the actual event, accompanied by sustained weakness throughout following periods.Forces Behind Today’s Market DeclineMarket analytics reveal the present Bitcoin downturn stems predominantly from futures market activity rather than direct spot market transactions. The Coinbase premium metric shifted negative, indicating diminished demand from United States-based investors.Cryptocurrency analyst IT Tech observed that although spot market selling decreased approximately $40 million, perpetual futures market selling reached substantially higher levels at $506.75 million. This evidence points toward leveraged trading positions as the primary catalyst for the pullback.Certain market participants anticipate possible near-term rebounds. Should Bitcoin successfully recover above $70,000 promptly, analysts project $76,000 as the subsequent resistance point. However, failure below $68,300 would expose support zones at $65,000 and $62,000.Bryan Tan from Wintermute proposed that “being flat is a strong position” under current conditions and advised maintaining liquidity reserves until markets establish more definitive directional momentum.External to digital assets, the wider economic landscape compounds existing pressures. Crude oil valuations have climbed approaching $120 per barrel, the VIX volatility gauge surged beyond 35 last week — marking its highest reading in twelve months — while gold retreated below $4,600.Moving forward, cryptocurrency markets confront another $13.5 billion derivatives expiration scheduled for March 27 through Deribit. Current positioning within that marketplace suggests preference for volatility-focused strategies over strong directional speculation.The post Bitcoin (BTC) Slides Under $70K as Markets Face Massive Derivatives Expiry Event appeared first on Blockonomi.
