25-Delta Skew

Where is the fear? Where is the greed? The vol surface tells you.

The 25-delta risk reversal measures the price gap between OTM puts and OTM calls. Negative means the market pays more for downside protection; positive means upside demand dominates. This page tracks triple-tenor risk reversals (7d, 30d, 60d), put/call decomposition, and ORIA skew regime classification across all six Deribit coins.
