What Happened

According to data from FiinGroup, margin lending across Vietnamese securities firms has tightened significantly, with the industry’s margin debt-to-equity ratio reaching 99.7% at the end of March 2026. Several major firms are approaching the regulatory cap of 200%, including HCM (195.4%), MBS (177.6%), KBSV (184%), and Mirae Asset (167.9%). Total margin debt stood at VND 412.7 trillion, a modest 2.9% increase from the previous quarter, but growth was highly divergent among firms.

While some firms aggressively expanded lending—VPS (+35.8%), LPBS (+17.9%), SHS (+15.5%), ACBS (+12.3%)—others scaled back, including SSI (-5.3%), VND (-8.6%), and VIX (-18.9%). The report also highlights a disconnect between margin lending and brokerage market share: VPBankS, with over VND 36 trillion in margin loans (third largest), held only a 2.94% market share on HOSE, while VPS, the top broker with 15.32% share, had only about VND 30 trillion in margin loans. This suggests a portion of margin funds may be used for non-trading purposes, raising concerns about shadow banking.

Market Context

The tightening margin environment comes as the VN-Index corrected 6.16% in Q1 2026, breaking a four-quarter winning streak that saw gains of 29%. Despite the correction, margin debt continued to rise, albeit at a slower pace. The leverage ratio (margin debt to free-float adjusted market cap) increased to 14.1% from 12.8% at end-2025, indicating rising leverage usage. Market liquidity remains below the Q3 2025 peak by about 23%, though it improved 22% quarter-on-quarter. HCM shares closed at VND 27 on April 15, up 3.08% on high volume, while MBS closed at VND 21, down 0.95% on April 10.

Strategic Significance

The high margin debt-to-equity ratios at several firms signal elevated systemic risk, particularly if the market continues to decline. The divergence between margin lending and brokerage market share suggests that some firms may be engaging in shadow banking activities, extending credit for non-trading purposes. This could amplify risks if borrowers face financial stress, as margin calls and forced liquidations could spread beyond traditional retail investors. The trend also highlights the growing influence of bank-backed securities firms, which may be using margin lending as a channel for broader credit expansion.

What to Watch

• Q2 2026 margin debt data from FiinGroup to see if the ratio continues to rise or stabilizes.
• Regulatory actions from the State Securities Commission (SSC) regarding margin lending caps or tighter oversight.
• Earnings reports from HCM, MBS, and other high-leverage firms for any signs of credit losses or provisioning.
• Market liquidity trends and VN-Index performance, as a sustained downturn could trigger margin calls.
• Any disclosures of non-trading use of margin loans by listed securities firms.
