Key Highlights:

Our weekly crypto derivatives analytics report delves into macro events, the current state of crypto and trading signals from spot trading volume, and futures, options and perpetual contracts.

December's end-of-year options expiration brought an unexpected drop as realized volatility fell to the lowest levels of the month. Perpetual swap open interest remained stable, indicating these markets weren't heavily used for hedging against expired options, likely contributing to the muted volatility. 

While most expired open interest in Bitcoin (BTC) and Ethereum (ETH) hasn't been reinvested, the balance of calls and puts remains consistent. Notably, ETH options are pricing in higher implied volatility as compared to BTC, particularly for shorter expirations, leading to a flat term structure for ETH, while BTC is offering cheaper options exposure.

In the perpetual markets, low volatility and minimal spot movements have led funding rates for nearly all tokens to mirror broader market sentiment throughout the holiday season. On the options side, BTC's term structure is noticeably lower and steeper than ETH's, with realized volatility now dipping below implied volatility levels, highlighting an intriguing shift in market dynamics.
