Reading BTC and ETH Derivatives Sentiment Through Funding, Skew, and Volatility

Summary

This weekly commentary compares Bitcoin and Ether derivatives conditions after Bitcoin reached a new record high and then traded within a range. For BTC, it reports that several directional sentiment measures remained positive, short-tenor volatility smiles favored out-of-the-money calls, funding stayed positive, and the one-month futures yield remained above 7%. It also says short-term volatility expectations fell after the high and rose again amid US-EU tariff discussions. The report frames these readings as evidence of continued, though weaker, optimism in derivatives markets despite the spot pullback.

Ether showed less bullish positioning: perpetual funding was below zero, while its volatility skew was less call-favoring than Bitcoin’s. The commentary notes a short-tenor volatility premium for ETH and compares the slope of short- and longer-tenor volatility. These are dated market observations, not a tested strategy or causal analysis. The document supplies no underlying charts or full data series, and its disclaimers stress that conditions can change and that historical information may not predict future outcomes.
