Specifically, all transfers exceeding the threshold will be automatically routed through regular clearing, the bank said in a statement. Transactions initiated after 3.55pm will be processed on the next working day.
MSB said the move aligns with regulations from the State Bank of Viet Nam on payment services and is aimed at strengthening system safety.
Previously, banks could split large-value instant transfers into smaller transactions below 500 million VND to ensure immediate processing via the national switching system operated by National Payment Corporation of Viet Nam.
Other banks, including Eximbank Viet Nam, TPBank and VPBank, have also announced similar measures.
The changes follow an amended circular on intermediary payment services, effective November 2025, which caps transactions processed through the central bank’s electronic clearing system at 500 million VND. Transactions exceeding this limit must be handled through standard channels, with longer processing times.
