The Manual, issued via Decision No. 71/QĐ-HHNH by the VNBA on September 30, 2025 , mandates unprecedented inter-bank cooperation, moving away from banks tackling risks individually.

Key features of the new framework include:
Rapid Processing: Establishing a standardized response time of a maximum of T+3 working days for all parties to coordinate and implement measures once suspicious activity is detected.
System-wide Coordination: Ensuring the swift exchange of information and execution of account freezes/suspensions across the network.
Clear Accountability: Defining the responsibilities of both the requesting bank and the receiving bank to ensure effective coordination.
During the launch event, Mr. Nguyễn Quốc Hùng, VNBA Vice President and Secretary General, stressed the need for solidarity: "The reality shows that handling fraud and deception requires close coordination among banks. It is almost impossible to ensure efficiency if each bank operates under its own regulations... fraudulent money flows very quickly".

The State Bank of Vietnam (SBV) welcomed the initiative, citing significant early success from enhanced vigilance. Mr. Phạm Anh Tuấn, Director General of the SBV’s Payment Department, noted that warning customers based on suspicious accounts had already helped prevent the loss of approximately VND 1,500 billion.
The VNBA will now serve as the focal point for oversight, ensuring the Manual becomes a truly cohesive "common shield" that protects both the banking system's reputation and customers' legal rights against increasingly sophisticated high-tech crimes.
