Texas Government Code - GOV'T § 404.032. Deposits

(a) The comptroller shall deposit state funds in depositories that satisfy the collateral requirements of this chapter.  The comptroller may deposit funds designated as demand deposits only in institutions designated as depositories by the comptroller.

(b) The comptroller shall monitor the financial stability of state depositories in which state deposits are held and take appropriate action to protect state funds.

(c) A state depository shall collect all checks, drafts, and demands for money deposited with it by the comptroller. If the depository uses due diligence, it is not liable for the collections until the proceeds of the collections are duly received by the depository bank.  An expense incurred in collection that the depository is not permitted to pay by reason of an Act of Congress or a rule or regulation adopted under such an Act by the board of governors of the Federal Reserve System or the board of directors of the Federal Deposit Insurance Corporation shall be charged to and paid by the comptroller out of money appropriated by the legislature for that purpose.

(d) The comptroller shall keep sufficient money on deposit in demand deposit accounts in depositories designated by the comptroller as clearing institutions to meet all current claims on the state.  Items received by the comptroller for collection shall be deposited with a clearing institution to be credited to the demand deposit account in the depository.  Checks, drafts, or warrants drawn by the comptroller for the payment of obligations due by the state may be drawn on such an account in such a depository or on the demand deposit account in another state depository so that the checks, drafts, or warrants of the state may at all times pass current as cash.
