Implied Volatility for Crypto Assets
How to use Kaiko’s IV data for better risk management.
(5 min read) This case study explores the background, methodology, and use case for Kaiko's implied volatility data.
Overview
One of the best ways of determining risk in financial markets is by calculating the implied volatility of an option. Implied volatility is a forward-looking measure of the expected volatility of an asset over a specified time period, derived from the market price of the option contract. It is an extremely useful tool for forecasting risk, but the distinct characteristics of crypto markets makes the computation uniquely complex.
Crypto Options Markets
Crypto options markets often have low trade volumes, missing quotes, and large bid/ask spreads, which makes determining a precise and sturdy measure for implied volatility (IV) over time a complex task. Further, existing measures lack transparency with unclear methodologies. Today, only BTC and ETH have option markets are developed enough to determine a precise measure for IV.
To solve for the challenges faced by option traders, Kaiko built a methodology specifically tailored for crypto markets, providing accurate, robust and stable implied volatilities for any crypto option strike and expiry.
With our methodology, IV is derived from the option market price for all strikes and expiries.
✓ volatilities updated every hour to capture market changes
✓ designed to be efficient in case of liquidity issues, accommodating for missing data
✓ space interpolation for non-listed strikes
✓ statistically more robust when compared with existing IV methodologies

Implied Volatility for Different Expiries
Having a sense of how much volatility is expected over the coming days, weeks and months allows investors to implement more robust risk management strategies. Looking at a range of expiries can give a general sense of the expected volatility of an asset, rather than looking at one specific time period.
In the below example, we take the average IV for all BTC option expiries that are at-the-money, and can observe a sharp drop from 64% to 54%, which suggests that BTC markets are calming down.
Different expiries have different measures for IV, which can help traders understand future risk. An inverted structure, in which short-term implied volatility is greater than the longer-term gauges, signals panic in the markets.
We saw this happen on November 28th, when the 2 week implied volatility for at-the-money options was greater than the 3, 2 and 1 month implied volatility for the same strikes. An inverted structure would mark a good time for a risk manager to reduce their market exposure and de-risk positions. A normal market structure for implied volatility would see the longer dated expiries have higher IV as more volatility should be expected over a longer timeframe.
Implied Volatility for One Expiry
Looking at implied volatility for one expiry offers a great apples for apples comparison of the expected volatility of two assets. In the below example, we compare the BTC and ETH implied volatilities for the rest of December by comparing their at-the-money IV’s for the Dec 30th Expiry. Interestingly we observed a +23% spread in the expected volatility of the two assets as of the start of December, with ETH’s implied volatility coming in at 75%.
Implied Volatility for Different Strike Prices
Implied volatility across different strike prices allow us to examine the effect of moneyness on implied volatility. When an option is in the money, it is more expensive as it is more likely to expire with value to the investor, i.e the option can be used. As we can see, implied volatility is highest for the in the money options as they command a higher premium – if they were to expire worthless the investor will have lost more compared to purchasing a cheaper, out of the money option. For context, the price of BTC at the time of the chart was roughly $16.9k.
How to Use Kaiko’s IV
Kaiko’s Implied Volatility data is available through our REST API. The endpoint returns a volatility curve for a listed expiry computed on a set of strike prices. The input takes the asset (BTC or ETH), time period, and expiry.
Conclusion
Analysis of implied volatility and its dynamics are important information in options trading, derivative risk management and even spot market analysis. The lesson learned from the FTX collapse, if not the whole of 2022, should be that risk management is a necessity going forward in crypto. Implied volatility and other metrics such as VaR and market liquidity can form the foundations of a well rounded risk management toolkit.
