SEC Opens 15% Flexibility Window for Bitcoin-Heavy Trusts

The US Securities and Exchange Commission has created a new 15% flexibility window for trusts with significant Bitcoin exposure, according to CryptoSlate. Eligible trusts may use a faster generic route to pursue investments or activities that fall outside their existing listing rules. The change gives qualifying products additional room to move beyond their current framework, although the available capacity may be limited for trusts using derivatives. Derivatives are measured using gross notional value under the approach, meaning their full stated exposure can count toward the flexible sleeve. As a result, derivative positions could consume the 15% allowance quickly. The development is relevant to Bitcoin-focused trust structures and the broader crypto market, while the supplied report does not identify individual trusts or specify any particular transactions enabled by the change.
