Crypto Derivatives: Analytics Report – Week 25

Weekly recap of the crypto derivatives markets by BlockScholes.

Key Insights:

After falling below $60K, a level last seen in October 2024, BTC reached a two-week high above $67K. Sentiment across risk-on assets has rebounded after President Trump confirmed the electronic signing of a Memorandum of Understanding (MOU) with Iran, pushing down oil prices and causing markets to re- evaluate the probability of a Fed rate hike by year-end. In derivatives markets, much of the bearish premium that options traders had assigned earlier in the month has reversed with 7-day skew reaching -2.2% and -0.7% respectively for BTC and ETH.

The moves towards a more permanent peace deal have also seen at-the-money implied volatility fall back towards its year-to-date lows, in line with a summer volatility lull that we’ve seen every year since 2023. 7- day ATM IV currently trades around 33%, only a few percentage points above the May YTD low of 28%.
