Miss. Code § 27-105-353
The board of mayor and aldermen or other municipal authorities of each and every city, town or village in the state are required to select a depository in the manner provided by law for the selection of county depositories, including the same intervals of time as counties for receiving bids from financial institutions for the privilege of holding public funds. Before being selected, a depository must be certified by the State Treasurer as meeting the capital ratio requirement specified in Section 27-105-5 or 27-105-6. An institution shall not be a qualified depository and shall not receive any municipal funds unless its ratio has been certified annually by the State Treasurer as meeting the prescribed requirement. Notwithstanding the foregoing, any financial institution whether or not meeting the prescribed ratio requirement whose accounts are insured by the Federal Deposit Insurance Corporation or any successors to that insurance corporation may receive municipal funds in an amount not exceeding the amount that is insured by that insurance corporation and may qualify as a municipal depository to the extent of that insurance as prescribed in Section 27-105-315.
