The observations concern the period before October’s Consumer Price Index release was scheduled for November 10 at 8:30 a.m. Eastern, or 13:30 UTC. They are not a post-release market update.
What the volatility comparison can tell us
Realized volatility describes swings that have already happened. Deribit defines DVOL as a forward-looking, annualized measure covering the next 30 days. Its calculation draws on option prices at expiries on either side of that horizon and interpolates between them.
The two readings describe different stretches of time. A turbulent week can lift the backward-looking measure and bring it closer to implied volatility without demonstrating that the cash price of protection has fallen.
DVOL condenses option pricing into a single index reading. It does not give the cash premium for a particular protective option, so it cannot alone tell a Bitcoin holder what buying protection through CPI would cost.
The Daily Digits separately estimates a 2.5% Bitcoin move, approximately $1,884, for a window containing CPI. It reports forward implied volatility of 47.9% for that window versus 38.9% afterward. The study does not disclose the exact expiry endpoints or quote timestamp, so that estimate cannot serve as a current, reproducible protection quote.
That event-window estimate also differs from DVOL’s constant 30-day horizon. Combining the two would blur the distinction between pricing around one release and pricing a month of uncertainty.
Neither measure supplies a directional forecast. Deribit’s explanation allows for large Bitcoin moves upward as well as downward, and an implied move sets no boundary on the eventual outcome.
