Reading BTC and ETH Derivatives Signals Around an ETF Catalyst

Summary

This weekly report interprets BTC and ETH futures, perpetual swap funding, and options volatility surfaces in the lead-up to an anticipated ETF announcement. It describes a kink in the at-the-money volatility term structure moving toward shorter expiries, while volatility beyond late January is said to remain around the mid-50s. BTC short-dated skew recovered alongside increased demand for out-of-the-money calls; ETH showed weaker one-week upside volatility and a more neutral one-month smile. Futures-implied yields rose, and funding rates for both perpetual swaps indicated strong demand for leveraged long exposure.

The report compares the two assets across annualized futures yields, 25-delta risk reversals, volatility smiles, and SABR-calibrated surfaces. It says BTC one-month volatility rose as the expected announcement approached, while ETH’s one-week and one-month volatility diverged. Surface z-scores are calculated against the prior 30 days of hourly implied-volatility observations at matching delta and tenor. These are snapshot interpretations, not a tested forecast or trading rule; the supplied text omits the underlying charts and tables, and the signals are specific to the report’s market window.

Key ideas

• The report links shorter-tenor BTC volatility changes to the approaching ETF announcement date.
• BTC short-tenor skew recovered as demand for out-of-the-money calls increased.
• ETH showed a different pattern, with falling one-week upside volatility and a more neutral one-month smile.
• Perpetual funding rates indicated strong demand for leveraged long positions in both assets.
• The surface z-scores compare implied volatility with the preceding 30 days of hourly observations at matching delta and tenor.
