The State Bank of Vietnam announced that it will buy U.S. dollars at VND25,500 per dollar on Mondays and Wednesdays. This new channel is meant to add more dong to the banking system during the year‑end peak, which could affect everyday borrowers and savers.

The bank also limited each institution to sell only enough dollars to bring its foreign‑currency position back to balance, according to the SBV plan. Experts estimate that every US$1 billion purchased would inject about VND25.5 trillion into the banking system, expanding the pool of dong available for loans and deposits.

Nguyen Quang Huy, CEO of the Faculty of Banking and Finance at Nguyen Trai University, said the spot purchases would increase dong supply, helping banks meet rising payment demand and stabilise interbank lending rates. A more stable interbank market can ease short‑term funding pressure on banks.

By early November, deposit rates had fallen about 0.5‑1 percentage point and lending rates had dropped 0.2‑0.5 percentage point as banks reduced rates following SBV guidance. The early decline shows how the added liquidity can translate into cheaper credit and better returns for savers.

The key point is that the SBV’s dollar‑buying programme is designed to flood the market with dong, which can lower borrowing costs for businesses and households while raising the earnings on new deposits.
