FTSE Russell Adds 8 Vietnamese Banks to All-Cap Index: VPB Leads $308M Inflow Forecast

Overview

FTSE Russell’s September 2026 semi-annual review added 27 Vietnamese stocks to the FTSE All-Cap index, including eight banks: VPB, VCB, STB, HDB, SHB, SSB, BID and MSB. MBS estimates the bank cohort will draw USD 308 million in foreign inflows, with VPB (VPBank, HOSE) the single largest beneficiary at USD 75.2 million. The changes take effect from the 21 September 2026 trading session.

What Happened

FTSE Russell published the results of its September 2026 semi-annual review of the FTSE Global Equity Index Series for Asia-Pacific ex-Japan and China on 21 August. Twenty-seven Vietnamese securities were added to the FTSE All-Cap index. Selection criteria covered market capitalisation, free float, liquidity and, critically, accessibility for international investors as measured by remaining foreign-ownership headroom. Several large, liquid names, including MWG, MBB, TCB and REE, were excluded because foreign room available to buy was too limited.

MBS’s analyst team estimates that passive ETF flows allocated to Vietnamese stocks will exceed USD 1.8 billion, with active FTSE-linked capital of USD 5-8 billion. For the eight banks in the list, MBS forecasts USD 308 million of inflows, with roughly USD 31 million in the first phase. The index changes take effect after the close on 18 September 2026 and apply from the 21 September session. FTSE will roll out the allocation in four phases, starting 21 September 2026 and completing in September 2027.

Market Context

VPB closed at VND 26,950 on 12 September 2026 on HOSE, with HDB at VND 26,800, STB at VND 77,300 and VCB at VND 58,200. The bank group has been a core holding for foreign investors, and the FTSE inclusion adds a mechanical demand layer on top of existing active positioning. The upgrade of Vietnam’s weight in the FTSE Emerging All Cap Index to 0.49% from 0.329% signals a step-change in the country’s representation, though the phased schedule means flows will be spread over roughly twelve months rather than arriving at once.

Strategic Significance

The inclusion is a structural, not cyclical, event: it expands the pool of mandated buyers for these banks regardless of near-term earnings. VPB’s USD 75.2 million estimate is the largest single-stock figure in the bank cohort, reflecting its Mid Cap classification and available foreign room. For VCB, already a Large Cap constituent, the incremental flow is smaller relative to its market capitalisation but reinforces its status as the benchmark bank exposure. The exclusion of MBB and TCB on room constraints highlights a persistent feature of the Vietnamese market: foreign-ownership limits, not fundamentals, determine index eligibility, which in turn shapes which banks capture passive capital.

What to Watch

• FTSE Russell’s final list confirmation from 7 September 2026, after the 4 September adjustment deadline.
• The first-phase implementation on 21 September 2026 and the size of actual versus forecast inflows.
• Foreign-ownership room disclosures for VPB, VCB, HDB and STB as passive demand builds.
• MBS and other brokers’ revised inflow estimates once the final constituent list is locked.
• The timing of phases two through four, running through September 2027.
