Negative Volatility Carry and Short-Dated BTC and ETH Option Strategies

Summary

This market commentary links large realized moves in BTC and ETH with implied volatility that rose less, leaving volatility carry deeply negative. It describes both assets’ volatility term structures as being in contango, while short-term skew reversed from put demand toward a call premium. The author also compares ETH and BTC volatility, noting a higher ETH realized-volatility premium and discussing how ETF flows and the Bitcoin halving could affect relative interest.

The proposed trade expression is to own short-dated, at-the-money calls while selling longer-dated, out-of-the-money calls, aiming to participate in a near-term rally while offsetting some option decay. The rationale is that negative carry may make short-dated gamma attractive, particularly if renewed flows add volatility. The note also summarizes option volumes, selected trades, and dealer gamma positioning. These observations and outlooks are tied to a specific market episode; the article provides no backtest, quantified risk analysis, or evidence that its directional scenarios will occur.

Key ideas

• Realized volatility exceeded implied volatility, producing negative volatility carry for BTC and ETH in the reported period.

• The author suggests owning short-dated at-the-money calls while selling longer-dated out-of-the-money calls.
• BTC and ETH differed in option activity and reported dealer gamma positioning.
• The trade rationale depends on future movement and volatility, and the article provides no backtest or quantified risk analysis.
