Crypto Gamma Exposure and the January 2023 Volatility Trigger
Summary
This review explains how low liquidity and options market maker hedging contributed to Bitcoin and Ether’s January 2023 rally. It connects improving expectations for central bank policy with renewed investor interest, then focuses on negative gamma: when dealers hedge rising prices by buying more underlying assets, their activity can amplify a move. Positive gamma tends to produce the opposite effect, as hedging involves selling into strength and buying into weakness. The article also defines the volatility trigger as the point where hedging behavior changes, and describes the absolute gamma strike as a level associated with concentrated positive gamma and possible support or resistance.
The review cites option positioning, trading volumes, implied volatility, liquidations, and futures and options metrics to support its account of the move. It argues that the rally’s continuation remained uncertain: liquidity had not broadly returned, options activity declined near a new gamma concentration, and the upcoming Federal Reserve communication could affect prices. The analysis is a dated market interpretation, not a tested trading system; gamma estimates and dealer hedging effects do not establish a guaranteed direction or outcome.
Key ideas
- Negative gamma hedging can amplify price moves as market makers buy into rallies and sell into declines.
- Positive gamma hedging tends to dampen price changes through selling into strength and buying into weakness.
- A volatility trigger marks a price area where market maker hedging behavior may switch.
- An absolute gamma strike can act as a potential support or resistance level because hedging is concentrated around it.
- The review links the 2023 rally to options positioning and macro expectations but emphasizes that follow-through was uncertain.
