A changed payment instruction before cutoff

An operations employee receives an email requesting that a large settlement be sent to a new beneficiary account. The message uses a familiar display name and refers to a real trade, but its account details differ from the approved standing instructions. The sender says the cutoff is close and asks the employee to avoid the usual callback. The team has an established independent verification and approval process and access to known counterparty contact information. No evidence yet authenticates the change. Students must distinguish a genuine trade from an authenticated settlement instruction and explain how time pressure should be handled. The case gives no permission to ignore a mandatory control or make an unsupported payment, and it does not establish that every instruction change is fraudulent.
