If a receiving bank fails to accept a payment order that it is obliged by express agreement to accept, the bank is liable for breach of the agreement to the extent provided in the agreement or in this chapter, but does not otherwise have a duty to accept a payment order or, before acceptance, to take action, or refrain from taking action, with respect to the order except as provided in this chapter or by express agreement. Liability based on acceptance arises only when acceptance occurs as stated in Alaska Stat. § 45.14.209, and liability is limited to liability provided in this chapter. A receiving bank is not the agent of the sender or beneficiary of the payment order it accepts, or of another party to the funds transfer, and the bank does not owe a duty to a party to the funds transfer except as provided in this chapter or by express agreement.
