The cryptocurrency market is bracing for a potential increase in volatility as a large number of bitcoin options contracts are set to expire at the end of September. According to data from Skew, a crypto analytics platform, there are about 120,000 bitcoin options contracts worth over $3 billion that will expire on Friday, September 29. This represents about 40% of the total open interest in the bitcoin options market, which stands at around $7.5 billion.
Bitcoin options are derivatives contracts that give the buyer the right, but not the obligation, to buy or sell bitcoin at a predetermined price and date. Options traders can use these contracts to hedge their exposure, speculate on price movements, or generate income by selling options premiums. The expiration of options contracts can have a significant impact on the underlying spot price of bitcoin, as traders may adjust their positions to either realize profits or avoid losses.
One of the main factors that influences the price of bitcoin options is implied volatility, which measures the expected magnitude of future price fluctuations based on the options prices. Implied volatility tends to increase as the expiration date approaches, as there is more uncertainty about the final settlement price. This can create a feedback loop, as higher implied volatility makes options more expensive, which in turn attracts more buyers and sellers, leading to more price movements in the spot market.

According to Skew, the implied volatility of bitcoin options has risen from around 65% at the beginning of September to over 80% as of September 27. This suggests that the market is anticipating a higher degree of volatility in the coming days. However, implied volatility is not a perfect predictor of actual volatility, as it can also be affected by other factors such as supply and demand, liquidity, and market sentiment.
Another factor that can influence the price of bitcoin options is the skew, which measures the difference between the implied volatility of out-of-the-money (OTM) options and at-the-money (ATM) options. OTM options are those that have a strike price that is either above (for calls) or below (for puts) the current spot price, while ATM options are those that have a strike price that is equal to or close to the current spot price.
A positive skew means that OTM calls have higher implied volatility than ATM calls, indicating a bullish sentiment in the market. A negative skew means that OTM puts have higher implied volatility than ATM puts, indicating a bearish sentiment in the market.
According to Skew, the skew of bitcoin options has been mostly negative in September, meaning that traders have been more interested in buying downside protection than upside exposure. This could indicate a cautious or pessimistic outlook for the future price of bitcoin, or simply a reflection of the higher demand for puts than calls in general.
However, the skew has also fluctuated significantly throughout the month, reaching as low as -20% on September 7 and as high as -2% on September 24. This shows that the market sentiment is not stable and can change quickly depending on new developments and events.
The expiration of bitcoin options contracts can also create opportunities for arbitrage and manipulation in the market, as some traders may try to influence the spot price to benefit their options positions. For example, if a trader holds a large number of OTM calls that are close to being in-the-money (ITM), they may try to push up the spot price by buying bitcoin in large quantities before the expiration date.
Conversely, if a trader holds a large number of OTM puts that are close to being ITM, they may try to push down the spot price by selling bitcoin in large quantities before the expiration date. These strategies are known as pinning and pushing, respectively, and they can create artificial price movements that affect other market participants.
The impact of the upcoming bitcoin options expiration on the spot market is hard to predict, as it depends on various factors such as the distribution of strike prices and maturities, the level of liquidity and trading activity, and the overall market sentiment and expectations. However, given the large amount of open interest involved and the high implied volatility observed, it is likely that there will be some degree of volatility and price action in the next few days. Therefore, traders and investors should be prepared for potential swings and surprises in the bitcoin market.
