Bitcoin Volatility Rises Ahead Of $23 Billion Options Expiry

Options are showing that Bitcoin is heading into the final weeks of 2025 under intense pressure, with around $23 billion in contracts set to expire next Friday that threaten to amplify already-elevated volatility.

The amount accounts for more than half of all the open interest on Deribit, the largest Bitcoin options venue. The looming buildup shows traders are pricing in continued downside risk in what’s become an even more perilous market. Bitcoin saw price swings of over $130 billion within an hour during US trading on Wednesday, triggering a cascade of both long and short liquidations. The broader crypto market has fluctuated around the $3 trillion threshold.

“Markets continue to slide as we head into the New Year, with prices sitting on a knife’s edge,” said Nick Forster, founder at digital assets trading platform Derive.xyz.

Bitcoin jumped as much as 4% to $89,430 on Thursday, before erasing the gains. The largest cryptocurrency by market value is down about 30% since reaching an all-time high of more than $126,000 in early October. It traded at $85,465 at 8 a.m. in Singapore on Friday.

“Bitcoin positioning remains decisively bearish. Thirty-day volatility has climbed back toward 45%, while skew hovers around -5%. Longer-dated skew is also anchored around -5%, signaling that traders are pricing continued downside risk through Q1 and Q2, as ongoing sell pressure from previously inactive wallets weighs on spot prices,” Forster said, referencing the measure of the relative cost of upside potential versus downside protection known as the skew.

Positioning around the Dec. 26 expiry reflects that divide. Call options are clustered at strike prices of $100,000 and $120,000, hinting at residual optimism for a year-end relief rally. Yet bears dominate the near-term picture, with heavy put option exposure accumulating at $85,000 — a level that STS Digital estimates holds roughly $1.4 billion in open interest and may act as a gravitational “magnet” into the options expiration date.  

Beyond the expiry, traders expect repositioning around two catalysts: hedging ahead of a Jan. 15 MSCI decision that could eject digital-asset treasury firms whose crypto holdings exceed 50% of assets from its indexes, and renewed call-overwriting flows. “Together, these flows should increase downside volatility while capping upside,” said Maxime Seiler, chief executive at digital asset trading firm STS Digital.

Sentiment remains fragile. Down 23%, Bitcoin is on track for its worst quarter since the second quarter of 2022, when the collapses of TerraUSD and Three Arrows Capital roiled the industry. Timothy Misir of BRN said Bitcoin’s inability to reclaim key levels leaves the market “trapped in a fragile holding pattern.”

“Overall, volatility remains elevated and positioning is defensive, but upside tails have not been fully abandoned as markets brace for a volatile start to the year,” Forster said.
