BTC & ETH volatility: smile, skew and the fear premium

Every day the options market puts a price on future moves — and it almost always errs to one side. Here we show that price (DVOL, the volatility smile, delta-25 skew) next to realized volatility — and how much more, or less, fear currently costs compared to reality.

How to read: DVOL — how much the market pays for future moves (with a rank: how high that is against the past year). HV — how much the price actually moved. The difference = the fear premium: when fear costs more than the facts deliver, whoever sells it gets paid. The smile — the price of insurance across strikes: a raised left edge = the market fears a fall. Δ25 skew — how much pricier puts are than calls at equal distance; Δ25 wings — how much pricier the tails are than the centre.
🎯 Today: BTC: price of fear 37 — bottom third of the year (percentile 16); fear premium -11.0 (facts exceed expectations — a rare state). ETH: price of fear 51 — very low against the year (percentile 13); fear premium -13.7 (facts exceed expectations — a rare state). ⚡ set a watch on a condition

🌡 Gauge: are options cheap or expensive right now?

BTC · options are CHEAP
DVOL 37 — percentile 16 of the year (further left = cheaper vs its own history) · vs the facts: -11.0 (facts above fear — a rarity)
ETH · options are CHEAP
DVOL 51 — percentile 13 of the year (further left = cheaper vs its own history) · vs the facts: -13.7 (facts above fear — a rarity)

“Cheap” — against its own one-year history (DVOL percentile). This is the state of prices now, not a forecast: cheap options can get cheaper still. For a buyer of movement cheap options are favourable; for a premium seller — the opposite.

📍 Now: on the front tenor the right edge is raised — the call wing costs more by 1.9 pts (calls pricier — moderate).

How to read the smile: each curve is the price of options (IV) across the strikes of one tenor; the vertical line is current spot. A raised LEFT edge = downside insurance costs more (the market fears a fall); a raised right edge — they pay for upside. Hover for the exact IV of every tenor at a strike.

How to read: what the “central” volatility costs for each maturity. Now: normal (contango): far options cost more than near ones — the usual price of time. A curve inversion is our verified marker of elevated movement ahead (the case file lives in our Ledger). On contango and inversion — glossary →.

drag to zoom · double-click to reset

📍 Now: implied 37 vs realized 48 → premium -11.0. The facts EXCEED expectations — a rare state: the move is already stronger than what the market prices in.

How to read: the blue line is what the market PAYS for future moves, the grey one is how much movement actually HAPPENED. When blue sits above — fear is overpriced and time works for the option seller; crossovers (facts above expectations) are rare buyer windows. The “VRP” button draws the premium itself: everything dipping below zero is a buyer’s window. Hover for exact values on any date.

📍 Now: percentile 15 of the year — very low. Historically, the weeks after readings like this brought an expansion of movement more often than continued quiet.

How to read: where today’s “price of fear” stands against its own one-year history. Below 20 — very low (historically the launchpad of big moves), above 80 — panic is already in option prices. The spot overlay shows WHAT price was doing in those zones.

📍 Now: 7-day skew -1.7 · 30-day +1.6 — calls pricier — moderate.

How to read: above zero — downside insurance (puts) costs more than upside bets: the market pays for protection. Sharp spikes — panic episodes; negative values — rare greed (calls pricier). Two lines — the short (7d) and the monthly (30d) horizons.
