N.Y. Pub. Auth. Law § 1948
All moneys of the authority from whatever source derived shall be paid to the treasurer of the authority and shall be deposited forthwith in a bank or trust company in the state designated by the governing body. The moneys in such accounts shall be paid out on check of the treasurer upon requisition by the governing body or of such other person or persons as the governing body may authorize to make such requisitions. All deposits of such moneys shall be secured by obligations of the United States or of the state of a market value equal at all times to the amount on deposit and all banks and trust companies are authorized to give such security for such deposits. To the extent practicable, consistent with the cash requirements of the authority, all such moneys shall be deposited in interest bearing accounts. The authority shall have power, notwithstanding the provisions of this section, to contract with the holders of any bonds as to the custody, collection, security, investment and payment of any moneys of the authority or any moneys held in trust or otherwise for the payment of bonds or in any way to secure bonds, and to carry out any such contract notwithstanding that such contract may be inconsistent with the provisions of this section. Moneys held in trust or otherwise for the payment of bonds or in any way to secure bond and deposits of such moneys may be secured in the same manner as moneys of the authority and all banks and trust companies are authorized to give such security for such deposits. Any moneys of the authority not required for immediate use or disbursement may, at the discretion of the authority, be invested in those obligations specified pursuant to the provisions of section ninety-eight-a of the state finance law. Subject to the provisions of any contract with bondholders and with the approval of the comptroller, the authority shall prescribe a system of accounts.
