Reading Crypto Volatility Curves and Positioning Vega Against Gamma
Summary
This market commentary examines BTC and ETH price action, realized and implied volatility, term structures, skew, option flows, and dealer gamma positioning. It interprets the steepening volatility curves as a preference for longer-dated vega exposure over short-dated gamma. It also discusses a narrowing ETH-BTC volatility spread, attributing the discount in ETH volatility partly to skepticism about its realized volatility and supply from call overwriters. The author proposes buying the spread in a longer maturity while using shorter-dated spreads to offset gamma exposure.
The report connects BTC’s rebound with a shift toward call premium at many expiries, while describing concentrated ETH dealer long gamma as a potential constraint on price movement near expiry. It suggests an ETH call ladder to collect decay with downside protection. These are discretionary, date-specific trade views, supported by reported market levels and positioning rather than a systematic test. The article does not quantify the strategy’s payoff or execution risks, and its conclusions depend on the cited positioning and volatility conditions persisting.
Key ideas
- A steepening volatility term structure can reflect greater demand for longer-dated vega than near-term gamma.
- The ETH-BTC implied volatility spread may trade below realized volatility differentials when traders discount ETH volatility.
- BTC skew shifted toward calls across much of the curve after a spot recovery, while the shortest tenor retained put skew.
- Dealer gamma concentrations may influence spot behavior near option expiries.
- The author outlines a long-dated ETH-BTC volatility spread and an ETH call ladder, but supplies no systematic performance test.
