Reading Crypto Options Flows During the May 2021 Selloff
Summary
This weekly market commentary tracks BTC and ETH options activity during the sharp May 2021 selloff. It describes short option positions being closed, put and call trades at selected strikes, changes in implied volatility and skew, and the effect of hedging on spot moves. The author interprets elevated put skew and demand for downside protection as signs of hedging, concern, or speculation, while near dated volatility rose amid expectations of further movement. ETH straddle buying is presented as positioning for a large move without expressing a direction.
The commentary also cautions that, in a disordered fast market, individual trade details may reflect urgent risk reduction rather than a directional view. It uses observed flows and volatility measures to offer interpretations, but does not establish traders’ motives or provide a systematic test of predictive value. The notes cover only a short episode and specific market conditions, so they are best read as examples of options market forensics rather than general trading rules.
Key ideas
- The commentary links forced short option closures and hedging with sharp volatility and spot moves.
- Put skew and put buying are interpreted as signs of downside protection demand, though motives may vary.
- Straddle buying expresses an expectation of movement without specifying its direction.
- In fast, disorderly markets, individual trades may reflect risk management rather than directional conviction.
- The flow interpretations describe a brief market episode and are not a tested predictive strategy.
