SSI, TCBS Lead Vietnam Securities Capital Race as Margin Debt Hits VND 435,000B

Overview

Vietnamese securities firms are competing to raise charter capital, with TCBS reclaiming the industry lead at VND 33,293 billion after issuing nearly 555 million dividend shares, while SSI (HOSE) stands at VND 30,033 billion following its own 500-million-share issuance. The race is driven by margin lending demand, which reached an estimated VND 435,000 billion market-wide by the end of Q2. VIX and HSC are also scaling up, making capital adequacy a competitive variable across the brokerage sector.

What Happened

The leadership position in the securities industry has changed hands repeatedly within just over a month. TCBS moved back to the top after completing a dividend share issuance that raised its charter capital to VND 33,293 billion, according to company disclosures dated 5 October. That followed SSI’s completion of a more than 500-million-share issuance from owner’s equity, which lifted its charter capital to VND 30,032.94 billion and briefly returned it to first place. SSI had already raised nearly VND 25,000 billion earlier in the year through an offering of more than 415 million shares to existing shareholders.

Behind the two leaders, VIX sits at nearly VND 26,000 billion and VPS at more than VND 24,000 billion. HSC accelerated after completing two issuance plans for existing shareholders and employees, lifting charter capital from nearly VND 10,808 billion to nearly VND 13,728 billion, with a full-year target above VND 15,000 billion through three issuance methods. The article attributes the race primarily to margin lending demand, noting that securities firms’ total outstanding loans may not exceed two times their owner’s equity, which ties lending capacity directly to capital size.

Market Context

SSI closed at 19,050 on 12 October 2026 on HOSE, while VIX closed at 11,700. The capital-raising wave spans the securities sector, where charter capital rankings have shifted with each issuance and the absolute gap between the top two firms has widened even as the order keeps changing. Margin lending remains concentrated among leading firms including TCBS, SSI, VPS, VPBankS and HSC, with market-wide balances estimated at VND 435,000 billion at end-Q2. Brokerage market share is a separate contest: VPS led Q3 2026 stock brokerage at 11.54%, ahead of SSI at 11.09% and TCBS at 10.03%.

Strategic Significance

For long-term investors, the relevant question is not which firm holds the largest charter capital in any given month, but how efficiently that capital is deployed. The two-times-equity cap on margin lending means capital size sets the ceiling on lending revenue, yet the article notes that large charter capital does not automatically translate into superior profit or market share. Cost of funding, risk management and collateral quality determine whether the additional equity generates returns above its cost. Firms that raise capital repeatedly through share issuance also dilute existing holders, so the pace of equity expansion relative to margin balance growth is the metric that separates value creation from simple balance-sheet inflation.

What to Watch

• Q3 2026 earnings releases from SSI, VIX and HSC, showing whether margin balances and lending revenue grew in line with the enlarged capital base.
• Further issuance tranches at HSC under its three-method plan to exceed VND 15,000 billion in charter capital this year.
• HoSE quarterly brokerage market-share data to track whether capital increases translate into share gains.
• Regulatory guidance on the two-times-equity cap for margin lending, which directly limits how much of the new capital can be lent.
• Updates on market-wide margin balances for Q3, versus the VND 435,000 billion recorded at end-Q2.
