It is not financially worthwhile to manually review alerts for instant payments. For traditional cross-border payments, the bank may be charging a considerable fee to the Sender (or Recipient) to send the payment. This fee covers (among other things) the cost of manually reviewing payments that trigger alerts. However, Nexus payments are likely to be low value, high volume and earn lower fees than traditional correspondent payments. This means the cost of staff time to review the payment will likely exceed the additional revenue generated by the payment.
