Overview

Vietnam’s State Securities Commission (SSC) inspectorate fined OCBS Securities VND 342.5 million for failing to retain audio recordings of 21 telephone order transactions and for an incomplete private bond issuance file. In the same enforcement round, two executives of HNX-listed Tập đoàn CMH Việt Nam (CMS) were fined VND 225 million each for concealing beneficial ownership of CMS shares to avoid disclosure obligations.

Key Facts

  • OCBS Securities fined VND 342.5 million in total across two violations.
  • VND 250 million of that relates to an incomplete private bond issuance advisory file prepared for a client in August 2025.
  • VND 92.5 million relates to missing records, including no audio for 21 phone-based securities orders executed in 2025.
  • CMS Deputy General Director Trần Văn Trung fined VND 225 million for trading CMS shares via a Trần Ngọc Linh account at MB Securities between 13 January 2022 and 22 September 2023.
  • CMS chief accountant Đinh Thị Thủy fined VND 225 million for trading CMS shares via a Nguyễn Thúy Dung account at FPT Securities between 3 December 2010 and 15 August 2024.
  • Combined executive penalties total VND 450 million; the SSC said both concealed beneficial ownership to evade information disclosure duties.

What Happened

The SSC inspectorate issued the penalties in separate decisions announced this week. OCBS Securities was cited under rules requiring securities firms to maintain complete records of client order activity. The regulator found that during 2025 the company did not archive call recordings for 21 securities transactions placed by telephone across several accounts. A second, larger penalty concerned the firm’s advisory work on a client’s private bond issuance in August 2025, where the file did not contain all contents required by regulation.

Separately, the SSC penalized Trần Văn Trung, Deputy General Director of Tập đoàn CMH Việt Nam (CMS), and Đinh Thị Thủy, the company’s chief accountant. According to the regulator, Trung used a securities account held in the name of Trần Ngọc Linh at MB Securities to buy and sell CMS shares from 13 January 2022 to 22 September 2023. Thủy used an account in the name of Nguyễn Thúy Dung at FPT Securities over a much longer window, from 3 December 2010 to 15 August 2024. The SSC characterized both as concealing true ownership to avoid disclosure obligations. The decisions do not disclose the value or volume of the trades involved.

Market Context

CMS trades on HNX and last closed at 5,200 VND, a price level that places it among the smaller capitalized construction and materials names on the exchange. FPT, the broker named as the venue for Thủy’s account, trades on HOSE at 57,000 VND and is not accused of any wrongdoing; its mention reflects only where the nominee account was opened. The penalties are small in absolute terms relative to the Vietnamese securities market, but they extend a pattern of SSC enforcement focused on disclosure integrity and broker record-keeping rather than on trading manipulation.

Strategic Significance

For CMS, the enforcement matters less for the VND 450 million in fines than for what it reveals about governance at a small HNX-listed issuer: two senior officers, including the chief accountant, used nominee accounts over periods spanning years, with one window running from 2010 to 2024. That raises questions about the reliability of the company’s ownership disclosures and about internal controls around related-party trading. For OCBS, the bond-file deficiency is the more consequential finding, since it touches the advisory process for private placements, an area the regulator has scrutinized since the 2022–2023 corporate bond market stress. The missing call recordings point to operational compliance gaps that apply across the brokerage sector as order intake migrates to phone and chat channels.

What to Watch

  • Whether CMS files an updated ownership disclosure or issues a statement on the two executives’ current roles.
  • Any SSC follow-up on the private bond issuance OCBS advised on in August 2025, including issuer identity.
  • CMS’s next annual or semi-annual disclosure on related-party transactions and shareholder structure.
  • Broader SSC inspection results for other brokers on call-recording and order-retention compliance.
  • Trading liquidity and price reaction in CMS on HNX following the penalty announcement.
