In brief
- The “triple witching” of stock derivatives can impact crypto indirectly by shifting equity market risk appetite, which then flows into high-beta assets like Bitcoin.
- A larger, direct crypto event is the December 26 expiry of over $13.3B in Bitcoin options, where the “max pain” price is clustered between $100,000 and $102,000.
- Macro pressures, including potential Bank of Japan tightening and year-end institutional portfolio rebalancing, are compounding headwinds and limiting upside, Decrypt was told.
Bitcoin traders are gauging the potential ripple effects from the U.S. stock market’s quarterly “Witching Friday,” a major derivatives expiry that could influence risk appetite across asset classes during a week packed with macro catalysts.
Bitcoin is trading flat over the past 24 hours, and remains under $90,000 for the third consecutive day, according to CoinGecko data.
“Global markets are indeed facing multiple overlapping variables this week,” Tim Sun, senior researcher at HashKey Group, told Decrypt.
He pointed to U.S. nonfarm payroll data and the Bank of Japan’s monetary policy meeting as key events influencing liquidity and risk assessments, alongside the concentrated expiry of stock derivatives.
The triple witching event, which involves the simultaneous expiration of stock index futures, stock index options, stock options, and single-stock futures, typically creates volatility.
“It can have an effect, but usually indirectly,” Derek Lim, head of research at crypto market-making firm Caladan, told Decrypt. “The most likely transmission is through equity moves affecting risk appetite, which then hits crypto as a high-beta asset.”
Sun explained the transmission mechanism of risk appetite, citing Bitcoin’s elevated correlation with the Nasdaq, with the recent uptick in institutional participation.
“When large-scale derivatives expirations trigger position adjustments, institutions typically engage in cross-asset liquidity management. This means that sharp volatility in U.S. equities can easily lead to passive rebalancing in crypto markets,” he said.
Historical patterns, however, show mixed results.
A March witching triggered a “sharp slide” in crypto after the expiry, while a June event saw Bitcoin and Ethereum drop nearly 2%, followed by a month-long consolidation, Lim noted. At the same time, the September event had a more contained impact.
A put-call ratio near 1.10 and other metrics show a defensive posture among traders, with inconsistent exchange-traded fund flows and shrinking holiday liquidity adding to the headwinds.
These headwinds are compounded by conflicting macro signals, Sun noted.
While a recent uptick in the U.S. unemployment rate has strengthened expectations for 2026 rate cuts, this positive is being offset by other forces. “Growing attention on the Bank of Japan’s potential tightening path may trigger the unwinding of carry trades, leading to capital outflows from high-beta assets such as Bitcoin,” he said.
Concerns around the sustainability of AI-related capital expenditures in U.S. equities further constrain upside potential in a tight liquidity environment.
Bitcoin’s $13.3 billion options expiry
With the impact of the triple expiry indirect, Lim deferred to a crypto-specific event looming next week.
“In my opinion, the December 26 Deribit expiry is the bigger event to watch, not the December 19 witching,” he said. That event involves over $13.3 billion in Bitcoin options expiring, with more than half of the current open interest clustered around it. The “max pain” strike is between $100,000 and $102,000, a price level where most options would expire worthless.
Adding to the year-end pressure, Sun highlighted that institutional investors are now in a portfolio rebalancing phase. “During this process, some capital may choose to reduce risk exposure and lock in annual gains, which could create temporary selling pressure or amplify volatility across risk assets, including Bitcoin,” he said.
The bottom line, according to the analysts, is a day of choppy trading with the highest volatility window in the late U.S. session and a moderate probability of a notable crypto impact driven primarily by equity markets. The larger test for Bitcoin’s price will come with the December 26 options expiry.
On prediction market Myriad, owned by Decrypt’s parent company Dastan, users remain optimistic about Bitcoin’s prospects, placing a 68% chance on Bitcoin’s next move taking it to $100,000 rather than $69,000—up from a low of 60% yesterday.
