Bitcoin and Ether Options: Call Skew, Volatility, and Relative-Value Views
Summary
This commentary interprets a Bitcoin rally through institutional flows and crypto options markets. It points to sustained inflows into U.S. Bitcoin exchange-traded funds and relative resilience during tariff-related market moves as evidence for the author’s view that demand has become more institutionally driven. It then reviews realized and implied volatility, observing a rise in Bitcoin volatility and a decline in Ether’s, while implied volatility moved higher at the front end. The article characterizes carry as neutral for both assets because implied and realized volatility were aligned.
The options discussion finds call premium across Bitcoin’s skew curve and a smaller call bias at the front of Ether’s curve. It also describes a rich-looking back-end ETH/BTC volatility spread and suggests that traders expecting the assets’ realized volatility to move more closely together could consider selling the spread. These conclusions are snapshots from a particular market week, and the proposed relative-value trade depends on future co-movement. The commentary offers no backtest or evidence that its market interpretation or trade idea will remain valid.
Key ideas
