Crypto Futures Yields, Perpetual Open Interest, and BTC–ETH Volatility
Summary
This commentary compares Bitcoin and Ether derivatives after the announcement of spot Bitcoin ETF approval. It reports that annualized futures-implied yields declined from earlier leveraged-long highs but stayed above 10% across maturities. Shorter-tenor yields rose faster, producing a renewed inversion. Perpetual open interest moved in opposite directions: Bitcoin interest continued to fall, while Ether interest and spot price rose. The authors interpret this rotation as possible positioning for an Ether ETF, while noting that both tokens’ perpetual funding rates remained positive.
The volatility discussion says that at-the-money term-structure inversions had resolved as short-dated event risk passed, with volatility returning toward longer-tenor levels. Ether nevertheless traded at a volatility premium to Bitcoin. These observations describe a particular post-announcement period and support possible interpretations of positioning and event risk; they do not prove that traders expected an Ether ETF or that the reported yield and volatility patterns would persist.
Key ideas
- Bitcoin futures-implied yields fell but remained above 10% across maturities, with short-tenor yields rising faster.
- Bitcoin perpetual open interest declined while Ether perpetual open interest rose alongside Ether’s spot rally.
- The authors interpret the shift in open interest as possible positioning around an Ether ETF, rather than proof of that expectation.
- Volatility term-structure inversions resolved as event risk passed, while Ether volatility remained higher than Bitcoin’s.
