Block Scholes x Bybit Crypto Derivatives October 9th
The uncertainty associated with the upcoming U.S. election remains evident for the term structures of both BTC’s and ETH’s implied volatility. While implied volatility levels have been trending downward, realized volatility has been on the rise in early October, driven by recent short-lived fluctuations in spot prices. The downward trend in implied volatility levels contrasts with the buildup of positioning that we typically observe ahead of known event risks, as we saw ahead of the release of BTC Spot ETFs in January 2024.

Key Insights
Futures: Futures trading volumes have noticeably declined since late September, with recent volatility prompting some increased activity. Open interest remains stagnant, with levels still lower following the September expiration.
Perpetuals: Open interest has remained stable. Last week's surge in trading volumes, driven by spot price volatility, underscores the typical relation between market turbulence and increased activity.
Options: The U.S. presidential election remains a central theme in market narratives and positioning, as ETH and BTC implied volatility is declining while realized volatility is trending upward.

Futures Trade Volumes Fall Significantly
Futures trading volumes have shown notable movements over the past few weeks. Activity remains noticeably lower on weekends, but there’s been a gradual reduction in overall activity since the spike in trading that occurred in late September. Despite this downward trend, futures markets experienced a positive response to the heightened volatility observed at the beginning of October, showing relatively enhanced activity. However, the levels of open interest lost during the September expiration haven’t yet been regained, and are exhibiting sideways movement that indicates a lingering impact from that period.

Perps Positioning Unchanged by October Volatility
Open interest in perpetual swaps has remained stable, with BTC continuing to dominate the landscape. This is a typical trend, reflecting a similar positioning in options markets, in which BTC exposure remains the focus. Last week we saw a significant outlier in trading volumes, particularly with BTC. This surge corresponds with the spike in spot price volatility observed at the start of October, reinforcing the usual relationship between volatility and trading volumes that we see across various instruments, as increased market turbulence tends to correlate with more activity.
Bybit Perp BTC & ETH Open Interest — Despite extra trade volumes in BTC last week, we haven’t seen a significant change in open interest levels.

Bybit Perp Trading Volumes — Weekend trade volumes continue to underperform weekday trading, with increased trading in BTC perpetuals over the past week.

Persistently Bullish Funding Rates End
BTC has maintained a bullish, positive funding rate over the past week, while ETH has experienced negative rates several times. This contrasts with the bullish trend seen in September. Meanwhile, TON has returned to positive funding after nearly a week of persistent rates for long positions. Other altcoins are showing mixed signals in response to lackluster spot performance, particularly DOGE, whose funding rate has declined from its late September highs as its spot price has reversed much of its gains.

BTC Options
BTC's realized volatility has risen once again, alongside a decrease in implied volatility that has led to a narrowing of the ratio between implied and realized levels (compared to recent levels since late September). This situation is unusual, given that the U.S. election kink in the volatility term structure is still present, now just below a 30-day tenor. Typically, we would expect short-tenor volatility levels to increase in anticipation of known event risks. Recently, we observed the largest trade volumes in call options in over a month, which has contributed to a recovery in open interest for calls, regaining the levels lost after the September expiration.

Volatility Trends Down
BYBIT BTC & ETH Volatility Term Structure — The volatility spike caused by the U.S. election has shifted along the term structure, while slightly dipping across tenors.

BYBIT BTC SVI ATM IMPLIED VOLATILITY — A downtrend in implied volatility can be observed for all tenors.

BYBIT BTC IMPLIED AND REALIZED VOLATILITY — The 7-day realized volatility has experienced a strong rise, and has now stabilized closer to implied volatility levels.

ETH Options
ETH's implied volatility has declined across the term structure, mirroring a downward trend that began in early September and similarly to BTC’s. The unpredictability associated with the U.S. election remains present, but hasn’t expanded as expected. This is unusual, considering the typical market behavior ahead of known event risks, such as the January BTC Spot ETF decision. While open interest for call options remains higher, it hasn’t yet recovered to the levels observed just before the September expiration. This indicates a cautious sentiment among traders regarding potential price movements. In contrast, trade volumes in put options have outweighed those of calls over the past week.
