Wherever these rules provide for the filing of a surety bond, the party may in lieu of filing the bond deposit cash or other negotiable obligation of the government of the United States of America or any agency thereof, or with leave of court, deposit a negotiable obligation of any bank or savings and loan association chartered by the government of the United States of America or any state thereof that is insured by the government of the United States of America or any agency thereof, in the amount fixed for the surety bond, conditioned in the same manner as would be a surety bond for the protection of other parties. Any interest thereon shall constitute a part of the deposit.
