Minn. Stat. § 47.0153

§ Subdivision 1. Emergency closings. When the officers of a financial institution are of the opinion that an emergency exists, or is impending, which affects, or may affect, a financial institution's offices, they shall have the authority, in the reasonable exercise of their discretion, to determine not to open any of its offices on any business day or, if having opened, to close an office during the continuation of the emergency, even if the commissioner does not issue a proclamation of emergency. The office closed shall remain closed until the time that the officers determine the emergency has ended, and for the further time reasonably necessary to reopen. No financial institution office shall remain closed for more than 48 consecutive hours in a Monday through Friday period, excluding other legal holidays, without the prior approval of the commissioner.

§ Subd. 2. Special observance closings. The officers of a financial institution may close the financial institution or one or more of the financial institution's offices on a day designated, by the President of the United States or the governor as a day of national mourning, rejoicing, or other special observance.
