Summary CME Group Bitcoin options open interest reflects heightened risk aversion, with volatility levels recently reaching multi-year highs. The substantial call open interest in the March expiry suggests that some investors may be expecting a price reversal. Analyzing where traders are placing their strike distribution provides further insight into market expectations. By Oliver Andrews Those watching Bitcoin ( BTC-USD ) prices lately have likely recognized volatility as a continued theme. After a recent drop from around $90,000 to near $60,000 in a matter of days, sentiment in the crypto market shifted rapidly to extreme fear. While the headlines were fixated on the sell-off, a different story is beginning to unfold in the options market. Data from CME Group shows a call-to-put open interest ((OI)) ratio of approximately 3:1 for March expirations, with $660 million in call options against $240 million in puts. This suggests investors are positioning for a potential recovery by the end of the first quarter. Volatility Hits 2022 Highs Between October 6, 2025, and February 6, 2026, bitcoin prices corrected approximately 50%. The most acute phase of this sell-off took place between January 29 and February 6, 2026, during which prices dropped from around approximately $90,000 to $60,000. Market uncertainty at the peak of this move was reflected in the 25-delta implied volatility (IV). On February 5, IV for calls and puts climbed to 75% and 95%, respectively, marking the highest readings since 2022. Although 25-delta put IV has since softened, it remains elevated relative to the 2025 average of 46%, indicating that the market hasn’t fully exhaled just yet. Leading up to the recent downturn starting January 29, 2026, trading volume for CME Group BTC options saw a sharp uptick on January 28, indicating a strategic shift toward liquid venues amid growing uncertainty. What the Risk Reversal Tells Us The 25-delta risk reversal ((RR)) – which measures the market’s willingness to pay for upside exposure versus downside protection – offers another clue to investor sentiment. On February 5, 2026, the RR fell to -19.34, its lowest level since 2022. This move deep into negative territory indicated the strongest preference for puts over calls in more than three years, with traders paying a premium to hedge against further depreciation. This isn’t necessarily a new trend – the persistent negative RR observed since August 2025 indicates a sustained preference for downside protection. While BTC futures prices and the RR typically exhibit a positive correlation, a notable divergence occurred between June and October 2025. During this period, the RR trended downwards even as prices appreciated. This suggests that investors were prioritizing the protection of unrealized gains, a move that, in hindsight, served as a potential early indicator of a price reversal. March Expiry Signals a Shift While the immediate past looks bearish, the future outlook is more nuanced. Open interest for February contracts was relatively balanced, with $260 million in put OI against $230 million in calls. However, looking at the March expiry reveals a clear bullish tilt, with demand driven by options buyers. Call open interest ($660M) is outpacing puts ($240M) by nearly three to one. This suggests that a significant portion of investors may be positioning for a recovery by the end of Q1 2026. However, the June expiry reflects a more cautious sentiment, with higher open interest in the puts than calls. Key Strike Levels to Watch Analyzing where traders are placing their strike distribution provides further insight into market expectations. Currently, put OI is concentrated between $60,000 and $90,000, with particularly high OI at the $60,000 and $80,000 levels. With Bitcoin trading near $70,000, a large portion of these hedges are in the money. On the other side, there is also a notable cluster of out-of-the-money (OTM) call OI between $110,000 and $220,000. Given the distance from current spot prices, these positions may represent call-overwriting strategies, where some investors sell deep OTM calls to capitalize on high IV and generate yield within a sideways or gradually recovering market. Additionally, the $80,000 call strike has high open interest, suggesting this level is a focal point for participants on both sides of the market. CME Group’s Bitcoin options suite currently reflects a divided sentiment. While the risk reversal highlights persistent risk aversion and expensive downside protection, the concentration of March call OI suggests a potential shift. Some traders appear to be using current volatility to position for a trend reversal or to lower their cost basis through yield-generating strategies.
