The U.S. Securities and Exchange Commission (SEC) has begun reviewing a rule proposed by NYSE Arca to strengthen crypto ETF listing standards, known as the '85% Eligible Assets Mandate,' Bitcoin.com reported. NYSE Arca is pushing for an amendment to its listing standards requiring commodity-based ETFs to hold at least 85% in verified assets. 'Verified assets' include eligible commodities, stocks, cash, and cash equivalents. Assets like BTC, ETH, SOL, and XRP can qualify as eligible assets because they have been traded in the futures market for more than six months. The report stated, "This amendment includes a provision that over-the-counter (OTC) derivatives will be calculated at their total notional value, leading to analysis that products with a high proportion of derivatives may find it difficult to maintain their listing." NYSE Arca explained that this amendment would prevent market manipulation and protect investors, and the SEC plans to make a final decision on approval after hearing industry opinions.
