A major quarterly derivatives event—known as quadruple witching—is set for Friday, with traders watching closely for potential ripple effects across bitcoin and broader financial markets.
The event occurs on the third Friday of March, June, September and December, when four key derivatives—stock index futures, stock index options, single-stock options and single-stock futures—expire simultaneously. The convergence typically drives a spike in trading volumes as positions are closed or rolled, often increasing volatility in equities.
Although final figures for the March 2026 expiry are not yet available, previous events highlight the scale. In March 2025, roughly $4.7 trillion in contracts expired, with the session recording the highest S&P 500 trading volume of the year, according to TradeStation.
Such large expiries often force institutional investors to rebalance portfolios, unwind hedges and adjust risk exposure in a compressed timeframe. Activity tends to intensify toward the close, when liquidity peaks and price swings can accelerate.
This quarter’s event comes against a fragile macro backdrop. Geopolitical tensions in the Middle East have pushed oil prices toward $120 per barrel, while gold has slipped below $4,600 and bitcoin has traded under $69,000. At the same time, the VIX volatility index has climbed above 35, signaling elevated stress across global markets.
While quadruple witching originates in traditional finance, its impact increasingly extends into crypto. Bitcoin’s growing correlation with equities means sharp moves in risk assets can spill over into digital markets.
According to Volmex Finance CEO Cole Kennelly, the event could trigger a pickup in cross-asset volatility, with the Bitcoin Volmex Implied Volatility (BVIV) Index already trending higher ahead of the expiry.
Historical patterns suggest bitcoin’s reaction on the day itself is often muted, with more meaningful moves unfolding afterward.
Following last year’s March expiry, bitcoin remained relatively stable initially before weakening in the weeks that followed. A similar pattern was seen in June, where a modest dip on the day led to further downside shortly after.
In September, bitcoin again posted limited movement during the event, but saw a sharper decline in the following week. December’s expiry produced a short-term gain, though the broader trend remained under pressure.
Overall, the pattern points to subdued price action during the event itself, followed by weakness in the days to weeks after.
Even if Friday’s expiry does not immediately drive volatility, crypto markets face another key catalyst shortly after. On March 27, around $13.5 billion in bitcoin options are set to expire on Deribit, with positioning suggesting a focus on volatility strategies rather than strong directional bets.
