Block Scholes x Bybit Crypto Derivatives 12th July
Futures: Future-implied yields have recovered from their spike lower, but continue their downward trend over the month. Perps: Despite the recent bearish price action, we don’t see a widespread or persistently negative funding rate in perpetual swap markets except for TON. Open Interest in majors has fallen during the period of spot market volatility as traders close out positions Options: ETH volatility trades at a 10–15 point premium to BTC’s at all tenor points on the term structure, has recovered its volatility smile skew toward OTM calls much faster than BTC, and has seen incredible trade volumes in calls that far outweigh the activity in its puts. ETH derivatives markets continue to reflect different positioning when compared to BTC, which may be linked to hopes and expectations of the imminent launch of its first Spot ETFs in the U.S. However, ETH’s volatility premium above BTC is not a new phenomenon, and is also reflected in the increased realized volatility with which it has moved for much of the past month.

Futures Volumes Rise During Spot Volatility
While annualized yields slipped lower during the selloff in Spot prices earlier in the week, both BTC and ETH futures have since recovered, although now trade at slightly lower levels. We also see a steeper term structure of yields in both markets as short-tenor futures trade much closer to Spot, while longer-tenor futures trade higher.
The expiration of June’s futures on June 28, 2024 didn’t see an explosive increase in trade volumes, but since then we’ve seen open interest has increased faster for ETH than for BTC, indicating a stronger narrative that’s focused on the launch of its ETF.

Perp Open Interest Tanks
The crypto-wide spot sell-off coincided with the largest single-day trade volume in perpetual swaps over the past month as traders rushed to cover exposure. The corresponding fall in open interest indicates that the much of the trade volume can be explained by long position holders closing out long positions in the perpetual swap contract. The larger trade volume activity in ETH suggests that traders were caught in long positions in greater magnitude, possibly due to positioning ahead of a expected ETF start-of-trading date.

Volatility (Finally) Delivers
The sharp sell-off in Spot prices at the beginning of the week and subsequent recovery means that the volatility realized by Spot moves has been higher than implied volatility expectations.
As a result, we see a sharp divergence in the comparison charts below for both BTC and ETH. The difference in each token’s realized volatility matches the difference in their implied volatility: ETH trades with an implied volatility premium that has so far been justified by its larger moves in comparison with BTC.

BTC Options
Options markets have had a relatively tame response to the most recent sell-off, with volatility levels rising at the front end to meet longer-dated levels. They’ve failed to meaningfully invert the term structure as we’ve seen them do in previous Spot price crashes. However, BTC’s volatility smile skewed further toward OTM puts at shorter tenors, indicating that markets are seeking protection against further downside price action.

ETH Options
The open interest in ETH calls is notably higher than puts following the June 28, 2024 expiration date. This corresponds with a high trade volume in calls that began around the beginning of the month, and has continued until today. It’s reflected in the more bullish skew toward OTM calls, which is in stark contrast to the bearish positioning seen in BTC’s markets.
ETH retains its volatility premium above BTC options, as all eyes turn to the launch announcement of several U.S. Spot ETFs.
