Reading Crypto Volatility Term Structures Around ETF Event Risk
Summary
This November 2023 market review compares BTC and ETH spot performance, realized volatility, implied volatility, and options skew. It attributes much of the month’s price rise to a weaker US dollar and notes that ETH outperformed BTC in both returns and realized volatility, while cautioning that one month does not establish a lasting change in their relative behavior.
The analysis uses volatility term structures and compares implied volatility with volatility delivered over the prior 30 days. Shorter BTC expiries remained near recent realized levels, while expiries from two months onward priced a larger premium, which the authors interpret as possible positioning around late January spot Bitcoin ETF decisions. ETH showed a similar pattern with a smaller premium. Elevated out-of-the-money call demand and persistent put skew suggest simultaneous interest in upside exposure and downside protection. These are market observations and interpretations, not a tested trading strategy; the proposed link to ETF deadlines and broader institutional adoption remains uncertain.
Key ideas
- ETH’s November outperformance included a return to higher realized volatility than BTC, but the data do not confirm a durable shift in their relationship.
- BTC options priced a larger volatility premium at expiries around and beyond the anticipated ETF decision window.
- ETH showed a similar implied-volatility pattern, with a lower premium than BTC.
- Call demand and persistent put skew indicated interest in upside participation alongside continued downside caution.
