Deribit DVOL: BTC Implied Volatility Index
Daily close of the Deribit BTC Volatility Index (DVOL), the BTC equivalent of the CBOE VIX. Computed from a strip of Deribit BTC options across strikes, it represents the market's expectation of 30-day forward annualised volatility on Bitcoin. Includes the March 2020 (152 percent), May 2021 (145 percent) and April 2025 (82 percent) implied-vol peaks. Sustained DVOL below 50 percent marks complacency; above 80 percent marks stress. AU trader framing on vol regime classification, options-pricing economics, and BTC AUD positioning.
Chart
Deribit BTC DVOL index, annualised 30-day forward implied volatility from BTC options. Long-run mean roughly 70 percent. Below 50 = complacency; above 80 = stress.
What is DVOL?
The Deribit BTC Volatility Index (DVOL) is computed from a strip of BTC options prices on Deribit, using the same model-free methodology that produces the CBOE VIX for equities. The index aggregates demand across strikes to produce a single annualised implied volatility number representing the market's expectation of 30-day forward BTC volatility.
DVOL is in percentage points, annualised. To translate to expected daily moves: divide by sqrt(365) ≈ 19.1 (BTC trades 365 days/year unlike equity sqrt(252)). A DVOL of 60 implies expected daily moves of about 3.1 percent. DVOL of 100 implies about 5.2 percent expected daily moves. Realised volatility tracks implied volatility with high correlation across multi-month windows.
Vol regimes since 2020
| DVOL range | Regime | Frequency | Interpretation |
|---|---|---|---|
| Below 40 | Extreme complacency | ~3% of days | Vol-spike risk; positioning crowded |
| 40-55 | Low vol | ~22% | Bull regime; trend-follow viable |
| 55-75 | Normal | ~45% | Default; balanced positioning |
| 75-90 | Elevated | ~18% | Mild stress; reduce risk |
| 90-110 | Acute stress | ~8% | Risk-off; cash heavy |
| Above 110 | Crisis | ~4% | Buy opportunity at extremes (with horizon) |
Trader takeaway
- DVOL is mean-reverting at multi-week horizons. Single-day spikes typically compress 20-40 percent over the following week. Sustained extreme readings (greater than 30 days at one regime) are rare; the dominant pattern is regime transitions through the middle.
- Low DVOL plus high OI is a vol-buy setup. When implied vol is low and open interest is high, the system has stored leverage waiting to be triggered. Long straddle or long DVOL via futures has high expected return over 4-12 week horizons.
- High DVOL marks contrarian-bullish for spot. March 2020 (152), May 2022 (95), November 2022 (88) all printed peak DVOL within 1-3 weeks of major BTC bottoms. The pattern is consistent: vol peaks coincide with panic selling and price bottoms.
- DVOL plus PCR is the sentiment matrix. Low DVOL + low PCR = complacent bull (early-cycle). Low DVOL + high PCR = boredom hedging (uncommon). High DVOL + low PCR = greed-driven vol (mania late-stage). High DVOL + high PCR = panic (oversold).
- AU-resident option access is Deribit-only. Australian-regulated options venues for BTC don't exist; AU traders use Deribit as offshore retail. DVOL signal value for most AU traders is in spot/CFD position sizing rather than direct options trading.

Frequently asked questions
DVOL is Deribit's BTC volatility index. It is computed from the prices of Deribit BTC options across a range of strikes, using the same model-free methodology that produces the CBOE VIX. DVOL represents the market's expected annualised volatility of BTC over the next 30 days. It is in percentage points; the long-run mean is roughly 65-75 percent. Daily moves of around 1.5 percent x 30-day-window translate to ~30 percent annualised volatility, so DVOL at 60 implies daily moves of about 3 percent.
Same methodology, different underlying. The CBOE VIX uses S&P 500 options to imply 30-day forward equity volatility; DVOL uses Deribit BTC options to imply 30-day forward BTC volatility. Range and magnitudes are very different: VIX long-run mean ~20 percent, DVOL long-run mean ~70 percent. Bitcoin is structurally more volatile than equities, with realised vol typically 50-80 percent vs 12-18 percent for S&P 500. The interpretation framework is identical: high vol = expected large moves = stress regimes; low vol = expected calm = complacency regimes.
High DVOL means the options market is pricing larger forward BTC moves. Three implications. (1) Options are expensive: buying calls or puts for directional speculation pays a higher premium. (2) Strangles and straddles (long vol) become more profitable to sell, less profitable to buy. (3) Sustained high DVOL marks stress regimes (March 2020 COVID, May 2021 deleveraging, May 2022 Luna). Historically these regimes resolve with sharp directional moves over the following weeks. DVOL is mean-reverting; spikes above 100 percent are rare and typically compress within 30-60 days.
Complacency. Sustained DVOL below 50 percent marks low-vol regimes where the options market expects small moves. These regimes tend to be late-cycle and precede vol shocks; the structural pattern is that low-vol windows compress speculative positioning into crowded trades that unwind when vol spikes. The August 2024 yen-carry-trade unwind hit BTC right after DVOL had been sub-50 for several weeks. Reading low DVOL with high open interest is the cleanest setup for buying vol (long straddles, long volatility ETPs).
Two channels. (1) Volatility drives option premiums; AU-resident traders accessing Deribit (offshore retail) pay or receive the vol premium directly. (2) High DVOL forewarns of larger spot price moves; AU spot/CFD holders should reduce position size when DVOL spikes above 80 percent because realised vol typically follows implied vol with high correlation. (3) The 2:1 ASIC retail leverage cap on BTC CFDs is more punishing during high-DVOL regimes because realised drawdowns are larger; calibrate stops accordingly.
