The U.S. Securities and Exchange Commission (SEC) has released a document inviting public comments on a proposed rule change submitted by NYSE Arca. The proposal aims to amend the general listing standards for commodity trust shares, requiring that at least 85% of a product's net assets consist of assets meeting existing qualification standards. The remaining 15% may include commodities, commodity-type assets, or securities that do not individually meet these standards. The SEC document provides an example where a trust holding qualified digital asset commodities like BTC, ETH, SOL, and XRP, along with a small portion of non-qualifying digital assets, could still meet the listing standards if the qualified assets meet the proposed threshold. This rule could influence the future design of crypto and commodity trust products' listing structures, but it is currently in the comment phase and has not yet been approved.
