What Happened

According to Q1 2026 financial reports from 27 listed banks, aggregate customer deposits grew only 0.6% from end-2025, with growth concentrated in a few institutions. BIDV, the largest bank by deposits, saw its customer base reduce by VND 82,031 billion, the steepest absolute decline among all banks. MB, Techcombank, Sacombank, and ACB each reported outflows exceeding VND 15,000 billion. TPBank and VietBank experienced the highest percentage declines at 4.3% and 4.9%, respectively.

In contrast, HDBank and VPBank posted robust deposit growth of 10.8% and 8.7%, respectively, capturing a larger share of the market. VietinBank also recorded an increase, though the article does not specify the exact figure. The data suggests a reallocation of deposits away from state-owned and large private banks toward certain mid-sized and retail-focused lenders.

Market Context

BIDV (HOSE: BID) closed at VND 40,000 on April 15, 2026, down 0.12% on low volume. The deposit outflow may pressure BIDV’s net interest margin if it must replace cheap deposits with costlier funding. Techcombank (HOSE: TCB) closed at VND 32,000, down 0.16%, while Sacombank (HOSE: STB) fell 2.57% to VND 64,000. The sector-wide deposit contraction comes amid rising deposit rates and increased competition for retail savings, as the State Bank of Vietnam maintains a tight monetary stance.

Strategic Significance

The divergent deposit trends highlight a potential shift in competitive dynamics. BIDV’s large deposit base remains a strength, but the outflow may signal customer preference for higher-yielding alternatives or improved service from rivals. For HDBank and VPBank, strong deposit growth supports lending capacity and could improve funding cost advantages. The trend also raises questions about whether state-owned banks are losing market share to private peers, which could affect sector profitability and risk profiles.

What to Watch

• Q2 2026 deposit data for BIDV and other banks to see if outflows persist or reverse.
• Net interest margin trends in upcoming quarterly reports, especially for banks with large deposit declines.
• Any regulatory changes to deposit rate caps or reserve requirements that could influence funding costs.
• Market share shifts in the banking sector, particularly between state-owned and private banks.
• Foreign investor flows into banking stocks amid changing deposit dynamics.
