The U.S. Securities and Exchange Commission (SEC) has sent letters to issuers of highly leveraged ETFs, requesting that they fully address risk-related issues regarding proposed ETFs offering more than 2x leverage exposure (including some crypto products). Review of the relevant applications will be suspended until responses are provided. Named institutions include ProShares, which has already issued leveraged crypto ETFs. The SEC pointed out that highly leveraged products may amplify volatility and investor losses. Although there are already several tech and crypto-related leveraged ETFs in the U.S. stock market, the progress of the new batch of proposals may be affected. (Decrypt)
