Vietnam Shuts Down Millions of Bank Accounts Over Biometric Rules

Vietnam has begun a sweeping crackdown on bank accounts that fail to comply with its new mandatory facial biometric identification system, sparking debate over financial inclusion and whether cryptocurrencies like Bitcoin offer a viable alternative for affected users.

Vietnam just froze 86m bank accounts because account holders didn't comply with new biometrics laws that require a face scan or fingerprint for account verification.

If users don't comply by the 30th they'll lose their money. This is why we bitcoin. https://t.co/hIK30vn1XR

Biometric Verification Now Required

As of September 1, 2025, banks across Vietnam are closing accounts deemed inactive or non-compliant with new biometric rules. Authorities estimate that more than 86 million accounts out of roughly 200 million are at risk if users fail to update their identity verification.

The State Bank of Vietnam has also introduced stricter thresholds for transactions:

• Facial authentication is mandatory for online transfers above 10 million VND (about $379).
• Cumulative daily transfers over 20 million VND ($758) also require biometric approval.

The policy is part of the central bank’s broader “cashless” strategy, aimed at combating fraud, identity theft, and deepfake-enabled scams.

AI Fraud Sparks Government Action

The timing follows several high-profile fraud cases. In May, police dismantled a network that used AI-generated facial scans to bypass banking checks, allegedly laundering more than 1 trillion VND (around $38 million USD).

Officials argue that biometric authentication has already reduced fraudulent incidents in some cases, even if direct causality remains hard to prove.

Impact on Foreigners and Inactive Accounts

While many Vietnamese citizens have updated their biometric data without issue, the measure has disproportionately affected:

• Foreign residents and expatriates who cannot easily return to local branches.
• Dormant accounts that had been left inactive for years.

These logistical hurdles, such as linking one-time passwords to local numbers and synchronizing crypto wallets, have added friction, fueling arguments from the self-custody crypto community, which views Bitcoin as a hedge against centralized banking restrictions.

Bitcoin as an Alternative?

For crypto advocates, Vietnam’s move illustrates how access to fiat funds can suddenly depend on state rules or biometric checks. By contrast, holding digital assets in self-custody wallets removes reliance on banks and centralized identifiers.

However, this “Bitcoin refuge” comes with its own risks:

• Price volatility.
• The need for strict key management.
• Reliance on fiat bridges for daily spending.

Ultimately, Vietnam’s biometric banking purge underscores the tension between security, inclusion, and personal monetary sovereignty. While it may strengthen defenses against AI-driven fraud, it also raises fresh concerns about citizens’ right to access and control their own money.

As the digital economy expands, the balance between state control and individual financial freedom is likely to remain a flashpoint.
