Ethereum Volatility, Options Positioning, and the ETH–BTC Spread

Article Deribit Insights
Read the original

Summary

This market note links Ethereum’s volatility repricing to renewed interest in a possible spot ETF. It compares BTC and ETH realized and implied volatility, term structures, option skew, and dealer gamma. The reported week saw ETH volatility rise sharply after ETF news, while its front-end term structure gained more than Bitcoin’s and the ETH–BTC volatility spread moved in ETH’s favor.

The author discusses call overwriting near resistance, buying ETH calls relative to BTC, and using long calendar structures to collect theta when Bitcoin’s variance risk premium is elevated. Options flow and dealer positioning are used to explain why implied volatility might remain firm. These are market interpretations and proposed trades, not tested strategy results; the article offers no systematic performance evidence. Its outlook depends on spot moves, ETF expectations, and positioning, and the author notes that the timing of further gains is uncertain.

Key ideas

  • ETF-related news coincided with a sharp increase in ETH realized and implied volatility.
  • The note compares volatility term structures, skew, and dealer gamma positioning across BTC and ETH.
  • The author favors ETH calls relative to BTC calls based on the changing narrative and volatility spread.
  • Call overwriting and long calendar structures are discussed as ways to manage exposure or earn theta.
  • The proposed trades rely on market conditions and positioning rather than reported systematic backtests.
