The U.S. Securities and Exchange Commission (SEC) has overstepped its bounds when it rejected a proposed rule change for a BTC exchange traded fund (ETF), according to SEC Commissioner Hester Peirce. In an interview with CNBC Africa, Peirce said the securities regulator has no jurisdiction to look at the underlying asset\u2014in this case, Bitcoin\u2014when considering whether to approve a rule change proposal for an ETF. She explained, \u201cIt\u2019s not within our purview to go and look at how those markets are actually working. We should be focused on the market that\u2019s trading the security, which in this case would be the exchange traded product.\u201d https:\/\/twitter.com\/HesterPeirce\/status\/1022601549309198337 Several weeks ago, the SEC formally denied a second proposal to list and trade shares of the Winklevoss Bitcoin Trust on the Bats BZX Exchange. The approval would have paved the way for the launch of the first BTC ETF, but the SEC commissioners dismissed the amended proposal in a 3-1 vote, questioning whether the BZX Exchange is capable of deterring fraud and market manipulation. Peirce, who was the lone commissioner to vote in favor of the proposal, wrote in her dissenting opinion: \u201cBy precluding approval of cryptocurrency-based ETPs for the foreseeable future, the Commission is engaging in merit regulation. Bitcoin is a new phenomenon, and its long-term viability is uncertain. It may succeed; it may fail. The Commission, however, is not well positioned to assess the likelihood of either outcome, for bitcoin or any other asset.\u201d Explaining her position further, Peirce told CNBC that \u201cmajority of the commission said that the proposed change was actually not consistent with the governing statute, in this case that\u2019s the Securites Exchange Act.\u201d Her position, she said, was that \u201cthe change before us was consistent with the Exchange Act\u201d and \u201cthere\u2019s no reason for us not to allow this product to go ahead and trade on the exchange.\u201d \u201cThey cited a number of reasons for that decision and specifically in this case, what I think they did is they looked through to the underlying asset, in this case that would be , and they raised some concerns about the market for that underlying product. I think by doing that, they went beyond what the statute allows us to do, and we should\u2019ve really focused on the market where the exchange traded product would trade as opposed to focusing on the underlying Bitcoin markets,\u201d Peirce said.
