Deribit BTC options 24-hour put/call volume ratio. Above 1.0 = defensive positioning. Below 0.5 = call mania. Long-run mean roughly 0.75.
What is the put/call ratio?
A put option is a contract giving the holder the right to sell BTC at a specified strike price. A call option gives the right to buy. Traders buy puts to hedge downside or speculate on declines; they buy calls to speculate on upside. The ratio of daily put volume to call volume thus captures the directional bias of options flow.
The Deribit BTC PCR is computed as a 24-hour rolling ratio of put-class contract volume to call-class contract volume across all strikes and expiries. Deribit is the dominant BTC options venue, clearing more than 80 percent of global volume, so its PCR is essentially the BTC options market PCR.
PCR regimes since 2020
| PCR | Regime | Historical examples | Implication |
|---|---|---|---|
| Below 0.5 | Call mania | Apr 2021, Mar 2024, Nov 2024 | Cycle-top warning; reduce risk |
| 0.5-0.7 | Bullish bias | Q4 2023, much of 2024 | Healthy bull regime |
| 0.7-0.9 | Neutral / balanced | Default; ranging markets | No edge from PCR alone |
| 0.9-1.05 | Defensive bias | Pullbacks, late-stage corrections | Risk-off mood building |
| Above 1.05 | Capitulation hedging | May 2022, Nov 2022, Apr 2025 | Contrarian bottom signal |
Trader takeaway
- Extremes are the contrarian signal. Sustained PCR below 0.5 marks cycle tops; sustained PCR above 1.0 marks cycle bottoms or major corrections. The 5-day rolling mean is more reliable than single-day spikes.
- PCR plus DVOL gives sentiment matrix. Low PCR + low DVOL = complacency (early-cycle bull, healthy). Low PCR + high DVOL = greed-driven vol (late-cycle mania). High PCR + high DVOL = panic (oversold). High PCR + low DVOL = boredom-led hedging (low-probability signal).
- Single-day PCR spikes have little signal value. News-driven days, expiry days, and quarterly rebalancing can produce 24h PCR swings of 30-50 percent that revert in 48 hours. Use trailing mean for regime-classification.
- BTC options are open during US-market-hours mostly. Deribit liquidity is highest 13:00-22:00 UTC (US session) and weakest during weekends. AU-resident traders should be aware that early-week PCR readings can be noisier due to thin weekend liquidity carrying into Monday Asia session.
- AU-resident options access is via Deribit (offshore). No AU-regulated BTC options platform exists. AU traders accessing Deribit do so as non-resident retail. PCR signal value is mainly for AU spot/CFD position sizing, not direct options trading.

Frequently asked questions
The 24-hour traded volume of BTC put options divided by the 24-hour traded volume of BTC call options on Deribit. A ratio above 1 means more puts traded than calls (defensive / hedging-led positioning). A ratio below 1 means call volume dominates (upside-speculation-led positioning). Deribit clears more than 80 percent of global BTC options volume across all strikes, so its put/call ratio is the de facto reference for the BTC options market. Contrast with the open-interest put/call ratio (a stock variable) which moves more slowly.
Three reasons. (1) Options flow is institutional. Most options volume on Deribit is from hedge funds, prop trading firms, and sophisticated retail; the put/call ratio is therefore a leading institutional sentiment indicator. (2) Put-buying creates downside-protection demand that often precedes spot selling. (3) Call-buying creates gamma demand from option market makers, who then hedge by buying spot. Sustained extreme readings (above 1.1 or below 0.5) mark sentiment crowds that typically resolve within 2-6 weeks.
Contrarian-bullish at extremes. A very high ratio (above 1.1) means everyone is hedging downside, options-market participants are paying premium for puts, and crowds are positioned defensively. Historically these readings mark late-stage capitulation. The May 2022 Luna PCR peak (1.22), the November 2022 FTX-collapse PCR peak (1.30), and the April 2025 tariff-shock PCR (1.05) all marked oversold extremes within weeks. Sustained 0.7-0.9 is the normal range; the contrarian read kicks in above 1.05.
Contrarian-bearish at extremes. Sustained ratios below 0.5 mark mania-grade call buying. The April 2021 cycle peak coincided with PCR of 0.42; March 2024 ETF-launch peak coincided with PCR of 0.48; November 2024 Trump-rally peak coincided with PCR of 0.45. The pattern is consistent: extreme call-heavy positioning marks cycle inflections. Note this is the most useful at multi-week sustained levels rather than single-day spikes.
Same concept, different range. The CBOE equity PCR typically ranges 0.4 to 1.5 with a long-run mean around 0.85. Deribit BTC PCR ranges roughly the same but with more frequent excursions to the extremes because BTC options markets are smaller and more retail-tilted. The interpretation is identical: extremes are contrarian. The level around 0.7-0.8 is normal for both markets.
