Keep up with the latest in crypto market commentary as we share the insights from our institutional research partners.
In this edition, we share the latest crypto derivatives weekly from Block Scholes.
The extreme selloff in the crypto spot has hit ETH and altcoins harder than BTC, and this sentiment has been reflected in derivatives markets. ETH trades at a significant volatility premium to BTC’s, and its term structure has inverted far beyond the level of BTC’s flattening at the front-end. Short-tenor volatility smiles have skewed towards puts for both coins in an expression of bearish sentiment and covering of downside exposure. However, longer-dated tenors (all those beyond one-month, in fact) remain stubbornly skewed towards OTM calls. In addition, BTC’s perpetual swap funding rate has not traded negative throughout the most recent selloff, while ETH’s has not yet reached the depths of the Feb 3, 2025 selloff.
