Deputy Governor Phạm Tiến Dũng told a Smart Banking seminar on October 22 that hackers had infiltrated some bank systems for months without the security teams detecting them, until hundreds of abnormal transactions worth tens of billions of dong surfaced in the middle of the night. Banking systems process about 100 million payment transactions a day, worth 1.2 million billion VND. He urged banks to invest seriously in security monitoring and build resilience, from early detection and rapid response to restoring services after incidents, and noted that the State Bank has required separate transaction monitoring teams. General Director Nguyễn Hưng of TPBank said 99.5% of its transactions are digital, while warning that AI could also be exploited by attackers.

- Hackers Infiltrate Many Banks for Months Without Being Detected
At the Smart Banking seminar on October 22, Deputy Governor Phạm Tiến Dũng warned that hackers had remained in banking systems for months without detection by security teams, until hundreds of unusual transactions worth tens of billions of dong appeared in the middle of the night. Banking systems process about 100 million payment transactions worth 1.2 million billion dong each day, so cybersecurity risk is now directly tied to business operations, reputation and stability. He urged banks to invest seriously in security monitoring systems, improving early detection, rapid response and service recovery, and the State Bank has also required separate transaction monitoring units. At TPBank, General Director Nguyễn Hưng said 99.5% of transactions are conducted through digital channels, while AI could also be exploited by bad actors to make attacks more sophisticated.
- Deputy Governor: 'Banks Must Closely Monitor the Safety of Their Systems'
At the Smart Banking seminar on October 22, Deputy Governor Phạm Tiến Dũng said the banking system processes about 100 million payment transactions a day, worth 1.2 million billion VND. He pointed to cyberattacks that stayed inside bank systems for months undetected, until hundreds of abnormal transactions worth tens of billions of VND appeared overnight. He urged banks to invest seriously in security monitoring, covering early detection, rapid response and service recovery, rather than focusing only on defense, and the State Bank now requires separate transaction-monitoring units. At TPBank, General Director Nguyễn Hưng said 99.5% of transactions are digital, while noting that AI can also be exploited by attackers.
- Digital payments are not just about fast transfers but must also be well managed
Digital payments are evolving from fast money transfers into a key link in the digital economy, requiring data connectivity, transparent cash flows and stronger governance. At a conference held on October 14 as part of Vietnam Digital Payment Day 2026, leaders from the State Bank of Vietnam (SBV), banks and technology firms stressed the need to complete institutional frameworks, ensure security and user rights, and counter fraud and high-tech crime. NAPAS said VietQRPay has 45 banks and intermediary payment organisations participating, while VietQRGlobal has connected six countries. MISA's representative argued that digital payments only deliver value when linked to daily reconciliation and the management of receivables and cash flow.
- State Bank of Vietnam Deputy Governor Pham Tien Dung: No one can succeed standing alone
At a seminar on the morning of October 14 in Hanoi, organized by Tien Phong newspaper and NAPAS, Deputy Governor Pham Tien Dung stressed that digital transformation matters only when it improves people's real-life experience. He recalled how his family in 2019 had to go through a discharge payment process at Bach Mai Hospital that took about 1.5 hours and left patients exhausted, whereas the Bach Mai Care app now integrates appointment booking, advance payments and drug purchases on one platform authenticated via VNeID. He argued that digital payments underpin healthcare, tax, transport and tourism services, calling for fewer unnecessary steps, a complete legal framework and stronger customer protection. He also warned that fast-evolving AI and technology are bringing increasingly sophisticated cybercrime.
- VDSC: New State Bank of Vietnam directive may push some banks over credit growth limits
According to VDSC, State Bank of Vietnam Official Dispatch 9608 asks banks to cut listed deposit rates by at least 0.5 percentage points a year for terms of 6 months or longer, and to cut lending rates by 1.5–2 percentage points a year for production and business sectors. Non-compliant banks could face adjusted credit growth targets for the rest of 2026, lower quotas in 2027, or stricter safety ratios. VDSC estimates SHB, TPBank and Techcombank already exceed their 2026 credit growth limits after counting outright L/C purchases. Although at least 19 banks cut deposit rates on October 19–20, VDSC expects lending cuts to exert short-term pressure on net interest margins (NIM), with the impact varying across banks.
- Many banks lend at average above 11% ahead of rate cut
According to VnExpress's tally of 30 banks, average lending rates kept rising in September, with OCB highest at 11.38% a year, followed by Techcombank (11.24%), TPBank (11.03%) and BVBank (11%). Other private banks mostly quoted 10.2-10.8%, VIB, ACB, PVcomBank and several others were around 9-9.8%, while BIDV and Agribank were at 7.73% and 8.42%. On October 18, the State Bank of Vietnam asked banks to cut lending rates by 1.5-2 percentage points for production, business and priority sectors, and to lower deposit rates for terms of 6 months or longer by at least 0.5 points. Banks that do not comply may face measures, including reduced or lowered credit growth targets. The August average lending rate was 10.7%, 1.7 points above late last year.

Techcombank posted VND 28,900 billion (up 23.7%), while LPBank reported VND 10,421 billion (up nearly 9%).

- World's Largest Gold Fund Dumps Over 10 Tonnes of Gold as Prices Slide
SPDR Gold Trust, the world's largest gold fund, continued net selling of nearly 12 tonnes of gold in the 22/10 session, bringing total sales over 2 sessions to nearly 15 tonnes and cutting its holdings to about 1,046 tonnes. Spot gold fell more than 2.8% to around USD 4,025 per ounce at the close of 22/10, and briefly dipped below USD 4,000 per ounce in the morning session of 23/10. Tensions in the Middle East pushed crude oil prices higher, raising concerns about inflation and further Fed tightening, and gold has still not attracted sustained safe-haven demand even as US Treasury yields fell. US September CPI rose 0.6% month on month and 3.7% year on year, while PPI rose 1.3% and 6.3%. Markets price about an 84% chance the Fed holds rates steady at its 27-28/10 meeting and a 16% chance of a 25 basis-point increase; September PCE data due on 29/10 is the next key factor to watch.

The State Bank's central rate was set at 25,627 VND/USD, down 5 dong, while Vietcombank quoted 25,660-26,040 VND/USD (buy-sell).
- Company Linked to Billionaire Pham Nhat Vuong Announces Major Good News

- International Business : Global stocks nosedive as Meta dents AI optimism
Global stocks retreated as tech earnings failed to ease concerns about the AI outlook, with MSCI's All-World index set for its largest daily fall in two weeks, down 0.4 per cent. Meta beat third-quarter revenue expectations, but its plan to issue non-voting stock revived worries about its mounting capital commitments, and a New Mexico judge ordered it to pay a $25 billion penalty in a data privacy case. Brent crude rose nearly 3% to $112 a barrel, near a five-month high, after more Houthi attacks in Saudi Arabia raised supply risks. Investors moved into government bonds, pushing the US 10-year yield down to 5.05%, below France's for the first time in 13 years, while French yields have climbed above 5% amid concerns over social unrest and debt.
