Weekly recap of the crypto derivatives markets by BlockScholes.
Key Insights:
Yesterday, Chair Powell highlighted rising tension between the Fed’s dual mandate, as inflation risks remain elevated while the labour market softens, though he suggested tariff-driven inflation may be a temporary one-off increase. He stressed that the Fed is committed to returning inflation to 2% but can afford to wait for greater clarity, given high economic uncertainty and weak job creation, particularly for new entrants. Overnight, BTC traded down to about $66.7K, down roughly 1.3%, while ETH decreased to around $2,037, down about 1.1%. The reaction in derivatives markets mirrored sentiment, with BTC and ETH implied volatility rising across the curve. In BTC, futures positioning has become less bearish, though the inverted vol term structure and persistent demand for puts still point to downside hedging. In ETH, the term structure has flattened, but skew remains firmly negative, with short-dated puts trading at a clear premium to calls.

BTC Options

BTC SVI ATM IMPLIED VOLATILITY – The term structure of implied vol is inverted, leaving it at odds with the shape of ETH’s term structure.

BTC 25-Delta Risk Reversal – Puts are in relative demand as all tenors trade with a bearish skew of more than 6 points.

ETH Options

ETH SVI ATM IMPLIED VOLATILITY – Bearishness does not translate to higher vol expectations, as the term structure dis-inverts to a flat shape.
