DVOL, explained.
DVOL is Deribit's headline number for BTC implied volatility — one index built from option prices across the book, meant to answer "how expensive is vol right now?" Same job as India VIX on NIFTY, different scale. A DVOL of 45 is boring for bitcoin. A VIX of 45 on NIFTY would be a crisis.
What it measures
Deribit derives DVOL from live BTC option prices — multiple strikes and expiries rolled into a 30-day forward implied vol figure, annualized. It's not realized vol from past returns; it's what the option market is charging for future movement.
Construction is in the same family as VIX: model-based aggregation off the chain, published by the exchange, updated continuously. You don't back-solve it yourself unless you're rebuilding the index.
DVOL vs ATM IV vs our pages
DVOL
One index — 30-day forward, whole-book summary. Good for regime checks and headlines.
ATM IV
One strike near spot, one expiry. Moves faster on events tied to that date.
Our mark_iv pages
mark_iv per strike from archived Deribit snapshots — surface and term structure, not the DVOL ticker republished.
All three can disagree on the same day. Front-week ATM can spike on a Friday expiry while DVOL moves less because longer dates anchor the index. Skew matters too — puts bid up on a dip and DVOL rises even if spot stabilizes.
Typical levels — compare to BTC history, not NIFTY
NIFTY's India VIX often lives 12–18 in calm weeks; 25+ is stress. BTC realized vol is structurally higher — DVOL has a different baseline entirely. Rough mental bands for BTC DVOL alone:
- ~30–45 — quiet-to-normal BTC vol regime. Options aren't cheap, but not panic-priced.
- ~45–65 — elevated. Common around sharp moves, ETF headlines, funding stress.
- ~65+ — hot. Often follows cascades (liquidations) or major macro shocks.

What DVOL is good for
- Regime flag — is the book pricing calm or chaos vs the last month?
- Event check — spike into a known date (CPI, FOMC, ETF flow) often shows in front expiries first; DVOL catches the blend.
- Vol-selling context — short gamma / short vol strategies hurt more when DVOL is rising into your position, regardless of direction.
- Cross-check with liqs — DVOL jumping while liquidations print often means the move already happened and options are catching up.
What it doesn't do
- Direction — high DVOL ≠ bearish. Straddles benefit from movement either way.
- Timing — like VIX, spikes frequently lag the first leg of the move.
- ETH — DVOL is the BTC index on Deribit. ETH vol has its own chain; use ETH
mark_ivon our pages for that asset.
DVOL vs realized vol
Same IV-vs-HV logic as NIFTY — see IV basics. When DVOL sits well above recent realized vol, the market is paying up for uncertainty. When DVOL collapses below realized, someone is complacent or the move already printed through the options.
Mistakes
Importing India VIX thresholds
"VIX below 15 = sell vol" has no direct DVOL translation. Use BTC's own range.
Replacing the chain with one number
DVOL hides skew and term structure. A flat DVOL can mask a spike in near-dated puts — check the term structure.
Confusing mark_iv with DVOL
