A federal appeals court says the U.S. Securities and Exchange Commission needs to better explain why it turned down a request from Coinbase to develop regulations to cover the booming crypto asset sector — although the judges stopped short of reversing the agency's decision. The 3-0 ruling issued Monday by the 3rd U.S. Circuit Court of Appeals was a partial win for Coinbase Global Inc., which went to court after the SEC denied its July 2022 request that the agency make clear how securities laws apply to assets such as cryptocurrencies and tokens. Coinbase has argued that the SEC has been applying existing securities laws to digital assets, prompting a need for wide-ranging rules.
