Global markets are heading into a major quarterly derivatives event on Friday, known as quadruple witching, with traders closely watching for potential spillover effects into bitcoin and broader crypto markets.
The event, which takes place on the third Friday of March, June, September and December, marks the simultaneous expiry of four key derivatives: stock index futures, stock index options, single-stock options and single-stock futures. The convergence typically drives a surge in trading activity as participants close, roll or rebalance positions, often leading to sharp moves in traditional markets.
While official figures for the March 2026 expiry have yet to be released, past events highlight the scale. In March 2025, roughly $4.7 trillion in equity and index derivatives expired, with the session recording the highest S&P 500 trading volume of the year, according to TradeStation. Similar events have consistently produced elevated activity.
Such large expiries often force institutional investors to rapidly adjust portfolios, unwind hedges and rebalance risk. Much of this activity tends to cluster in the final hour of trading, when liquidity peaks and volatility can accelerate.
This quarter’s event comes against an already fragile macro backdrop. Geopolitical tensions in the Middle East recently pushed oil prices toward $120 per barrel, while gold slipped below $4,600 and bitcoin fell under $69,000. At the same time, the VIX volatility index climbed above 35 last week, its highest level in a year, signaling increased stress across financial markets.
Although quadruple witching is rooted in traditional finance, its effects increasingly extend into digital assets. Bitcoin’s growing correlation with equities means sharp moves in risk assets can quickly transmit to crypto markets.
Cole Kennelly, CEO of Volmex Finance, said the event could amplify cross-asset volatility. He noted that large derivatives expiries may already be influencing crypto, with the Bitcoin Volmex Implied Volatility (BVIV) Index trending higher into the event.
Historical patterns suggest bitcoin’s reaction on the day itself has often been relatively muted, with more pronounced moves emerging afterward.
Following the March 21 expiry last year, bitcoin saw limited immediate impact but later declined, eventually bottoming weeks later after broader market reactions to U.S. tariff announcements. A similar pattern played out in June, when bitcoin slipped modestly on expiry day before falling further to a local low within days.
In September, bitcoin again posted only a small decline during the event, but dropped sharply in the following week. December’s expiry saw a short-term gain, though prices remained under pressure within a broader downtrend.
Taken together, these instances point to a recurring dynamic: limited price action on the day of expiry, followed by weakness in the days or weeks that follow.
Even if Friday’s event produces only modest immediate moves, crypto traders are already looking ahead to their own key catalyst. On March 27, bitcoin options worth roughly $13.5 billion are set to expire on Deribit, with current positioning indicating strong demand for volatility strategies rather than clear directional bets.
