(a) A Participant's Security Entitlement is created when a Federal Reserve Bank indicates by book-entry that a Book-entry Ginnie Mae Security has been credited to a Participant's Securities Account.

(b) A security interest in a Security Entitlement of a Participant in favor of the United States to secure deposits of public money, including without limitation deposits to the Treasury tax and loan accounts, or other security interests in favor of the United States that is required by Federal statute, regulation, or agreement, and that is marked on the books of a Federal Reserve Bank is thereby effected and perfected, and has priority over any other interest in the securities. Where a security interest in favor of the United States in a Security Entitlement of a Participant is marked on the books of a Federal Reserve Bank, such Reserve Bank may rely, and is protected in relying, exclusively on the order of an authorized representative of the United States directing the transfer of the security. For purposes of this paragraph, an “authorized representative of the United States” is the official designated in the applicable regulations or agreement to which a Federal Reserve Bank is a party, governing the security interest.

(c)(1) The Federal Reserve Banks as Depositories have no obligation to agree to act on behalf of any Person or to recognize the interest of any transferee of a security interest or other limited interest in favor of any Person except to the extent of any specific requirement of Federal law or regulation or to the extent set forth in any specific agreement with the Federal Reserve Bank on whose books the interest of the Participant is recorded. To the extent required by such law or regulation or set forth in an agreement with a Federal Reserve Bank, or the Federal Reserve Bank Operating Circular, a security interest in a Security Entitlement that is in favor of a Federal Reserve Bank or a Person may be created and perfected by a Federal Reserve Bank as Depository marking its books to record the security interest. Except as provided in paragraph (b) of this section, a security interest in a Security Entitlement marked on the books of a Federal Reserve Bank shall have priority over any other interest in the securities.

(2) In addition to the method provided in paragraph (c)(1) of this section, a security interest, including a security interest in favor of a Federal Reserve Bank, may be perfected by any method by which a security interest may be perfected under applicable law as described in § 350.4(b) or (d). The perfection, effect of perfection or non-perfection and priority of a security interest are governed by such applicable law. A security interest in favor of a Federal Reserve Bank shall be treated as a security interest in favor of a clearing corporation in all respects under such law, including with respect to the effect of perfection and priority of such security interest. A Federal Reserve Bank Operating Circular shall be treated as a rule adopted by a clearing corporation for such purposes.
