(b)Bank discretion to suspend redemption. A Bank, upon the approval of its board of directors, or of a subcommittee thereof, may suspend redemption of stock if the Bank reasonably believes that continued redemption of stock would cause the Bank to fail to meet its minimum capital requirements as set forth in §§ 932.2 or 932.3 of this chapter, would prevent the Bank from maintaining adequate capital against a potential risk that may not be adequately reflected in its minimum capital requirements, or would otherwise prevent the Bank from operating in a safe and sound manner. A Bank shall notify the Finance Board in writing within two business days of the date of the decision to suspend the redemption of stock, informing the Finance Board of the reasons for the suspension and of the Bank's strategies and time frames for addressing the conditions that led to the suspension. The Finance Board may require the Bank to re-institute the redemption of member stock. A Bank shall not repurchase any stock without the written permission of the Finance Board during any period in which the Bank has suspended redemption of stock under this paragraph.
