Volatility expectations in market leaders bitcoin and ether continue to dwindle despite lingering macroeconomic uncertainty. Crypto exchange Deribit’s ether implied or expected volatility index (ETH DVOL) reached a lifetime low of 51 over the weekend, deepening six-month downtrend. According to crypto asset management firm Blofin’s volatility trader Griffin Ardern, consistent selling of options by structured products has contributed to the implied volatility slide. “Many sellers of these options are exchanges and third-party asset management institutions, and their customers are mainly groups that want to obtain fixed income, such as miners and whale groups,” Ardner told CoinDesk, explaining the unusually low volatility. Per some observers, now is the time to buy volatility, particularly in the ether market.
