Dealer Gamma, Options Skew, and Crypto Weekend Price Moves
Summary
This weekly review analyzes a sharp weekend rally in BTC and ETH through options positioning, volatility pricing, and derivatives flows. It explains that dealers holding short gamma may need to adjust hedges as prices rise, potentially amplifying moves, especially when leveraged short positions face losses or liquidation. The review compares at-the-money implied volatility with realized volatility, tracks changes in 25-delta call and put skew, and describes how front-end volatility and the term structure shifted around the rally. It also points to concentrated short-dated call buying and persistent BTC call open interest as evidence of bullish positioning.
The author considers short liquidations and weak weekend liquidity as possible contributors, using open interest, funding, cumulative volume delta, and liquidation data as context. These are interpretations of a particular market episode, not proof of a general causal relationship. The look-ahead recommends monitoring funding and short open interest near a large options expiry and an FOMC event; it provides no tested forecast or systematic strategy.
