31 U.S.C. § 9108: Obligations

the form, denomination, maturity, interest rate, and conditions to which the obligations will be subject; the way and time the obligations are issued; and the price for which the obligations will be sold. A Government corporation may buy or sell a direct obligation of the United States Government, or an obligation on which the principal, interest, or both, is guaranteed, of more than $100,000 only when the Secretary approves the purchase or sale. The Secretary may waive the requirement of this subsection under conditions the Secretary may decide. The Secretary may designate an officer or employee of an agency to carry out this section if the head of the agency agrees. This section does not apply to a mixed-ownership Government corporation when the corporation has no capital of the Government. Subsections (a) and (b) of this section do not apply to the Federal Intermediate Credit Banks, the Central Bank for Cooperatives, the Regional Banks for Cooperatives, and the Federal Land Banks. However, the head of each of those banks shall consult with the Secretary before taking action of the kind described in subsection (a) or (b). If agreement is not reached, the Secretary may make a written report to the corporation, the President, and Congress on the reasons for the Secretary’s disagreement.
