La. Stat. tit. 39 § 1219
Any fiscal agent bank, operating under the laws of this state for the purpose of paying bonds and coupons of this state, of any political subdivision, or of any depositing authority, shall set aside all such funds deposited by any depositing authority as trust funds, and it shall deposit and maintain with an unaffiliated bank, the security designated in R.S. 39:1221 in the same manner provided in R.S. 39:1221; R.S. 39:1223; R.S. 39:1224. This security shall be for the account of the depositing authority, and, as a guarantee against loss to either the depositing authority or the holders of the bonds and coupons, it shall at all times be equal to one hundred per cent of the balance on deposit in the trust funds.
The provisions of this Section shall apply, except as they may be in conflict with the laws of other states, to all funds deposited in any bank located in any state other than this state, where money is deposited or paid for the purpose of paying bonds and coupons of any depositing authority.
