The announcement will determine which Vietnamese shares enter FTSE’s global benchmarks, but only 10% of their investability weight will be added in September under a four-stage transition.
MARKET INSIDER — FTSE Russell will publish the final list of Vietnamese stocks eligible for its Global Equity Index Series on August 21, an important milestone before Vietnam’s reclassification from frontier to secondary emerging-market status takes effect on September 21.
The announcement will give passive funds their definitive September trading list and may accelerate positioning by active managers. However, the upgrade will not generate all projected inflows immediately: FTSE will initially add only 10% of each eligible stock’s investability weight, with the remaining inclusion spread across three reviews through September 2027.
Key Highlights
- FTSE Russell will publish Vietnam’s final eligible-stock list on Friday, August 21.
- Vietnam will enter FTSE GEIS from September 21 through four tranches of 10%, 20%, 35% and 35%.
- Potential passive inflows are estimated at around $1.5 billion once inclusion is completed, rather than entirely in September.
- Market capitalization, free float, foreign ownership availability and liquidity will determine which stocks qualify.
Why the August 21 announcement matters
FTSE Russell has already confirmed Vietnam’s promotion to secondary emerging-market status. The August 21 review will not revisit that decision; instead, it will identify the securities that qualify for inclusion and establish the portfolio changes index-tracking funds must implement in September.
The distinction is important. Country classification determines whether Vietnam belongs in FTSE’s emerging-market universe, while the forthcoming constituent review determines which individual companies are investable under the index provider’s methodology.
FTSE’s existing indicative list was based primarily on data from the end of 2025. Prices, free float, foreign ownership availability, liquidity and corporate events have changed since then, meaning the final August list may differ.
Passive funds do not select companies according to valuation or earnings forecasts. Once FTSE confirms the constituents and their index weights, managers tracking the relevant benchmarks must buy the designated shares sufficiently closely to minimize tracking error.
Active emerging-market funds are not required to follow the changes mechanically, but many use FTSE indices as performance benchmarks. They may therefore begin accumulating eligible large-cap shares before the effective date, particularly where they expect passive demand to support liquidity.
FTSE’s official timetable confirms that the September semi-annual review—and the final list of eligible Vietnamese securities—will be published on Friday, August 21, according to FTSE Russell
Vietnam will enter global indices in four stages
Vietnam will be removed from the FTSE Frontier Index Series in a single step during the September annual review. Its addition to FTSE GEIS and related global and emerging-market indices will occur much more gradually.
The first tranche becomes effective at the market open on Monday, September 21, 2026, when FTSE will apply 10% of the eligible stocks’ investability weight.
A further 20% will be added in March 2027, followed by 35% in June and the final 35% in September 2027. The cumulative inclusion factor will therefore rise from 10% to 30%, 65% and ultimately 100%.
| Review | Effective date | Weight added | Cumulative factor |
|---|---|---|---|
| September 2026 | September 21, 2026 | 10% | 10% |
| March 2027 | March 22, 2027 | 20% | 30% |
| June 2027 | June 21, 2027 | 35% | 65% |
| September 2027 | September 20, 2027 | 35% | 100% |
FTSE said the phased approach was designed to manage capital flows, liquidity and the funding required under Vietnam’s non-prefunding arrangements. After each tranche, the index provider will assess whether index trackers have been able to replicate the changes before proceeding with the next stage.
This schedule limits the likelihood of a single, exceptionally large wave of compulsory buying in September. It also means the upgrade could provide recurring catalysts over more than a year rather than one isolated event.
Which Vietnamese stocks could qualify?
FTSE Russell’s April watch list contained 23 indicative securities that had passed its eligibility screens using data available at the end of 2025.
The large-cap candidates were BIDV, Vietcombank, Vingroup and Vinhomes. FPT and Hoa Phat were classified as mid-cap securities, while the prospective small-cap group included Binh Son Refining and Petrochemical, Duc Giang Chemicals, Gelex Electric, Khang Dien House, Kinh Bac City, Masan Group, Novaland, Sacombank, SHB, SSI Securities, Vietcap Securities, Vietjet, Vinamilk, Gelex, Vincom Retail, VIX Securities and VNDirect.
That list remains indicative rather than final. FTSE will treat Vietnamese shares as new, non-constituent securities when it applies minimum-size and liquidity tests for the September review. Consequently, inclusion cannot be assumed simply because a stock appeared on the earlier watch list.
Market capitalization alone is insufficient. FTSE considers investable market capitalization—the value of shares reasonably available to international investors—alongside trading liquidity, free float and foreign ownership restrictions.
This creates an important difference between a company’s headline valuation and its potential index weight. A very large company can receive a limited allocation if insiders, the state or strategic shareholders control most of its shares, or if little foreign ownership capacity remains.
Conversely, a somewhat smaller company with a broad free float and consistently strong liquidity may be more accessible to global funds.
Recent IPOs remain subject to the same screens
Vietcap has identified TCX, VCK and MCH as recent listings that meet its estimated eligibility requirements, while VPX, GEL and HPA were assessed as falling below the relevant investable-market-capitalization threshold.
According to the brokerage’s calculations, VPX, GEL and HPA had investable capitalizations of approximately $404 million, $304 million and $54 million, respectively, compared with an estimated qualifying threshold of around $483 million.
These remain Vietcap estimates, not confirmed FTSE decisions. Index thresholds are recalculated periodically and can change with regional market movements, exchange rates and the review’s final measurement data.
FTSE’s methodology provides that newly eligible companies, including IPOs, will enter using the same phased factor applied to other Vietnamese constituents. A company added in the early stages will therefore not receive its full investability weight immediately.
From September 21, Vietnamese IPOs may also qualify for FTSE’s fast-entry process if they exceed the thresholds applicable to the Asia-Pacific region excluding China and Japan, the FTSE Russell website showed.
Passive inflows will be gradual, not immediate
Vietcap estimates that approximately $1.4 trillion is managed by passive funds tracking relevant FTSE benchmarks. Once Vietnam reaches its full index weight, the brokerage expects potential passive inflows of around $1.5 billion.
FTSE’s projected March weights placed Vietnam at approximately 0.034% of the FTSE Global All Cap Index, 0.329% of the FTSE Emerging All Cap Index, 0.020% of the FTSE All-World Index and 0.192% of the FTSE Emerging Index.
Even small percentages can translate into substantial purchases when applied to global funds with hundreds of billions of dollars in assets.
The phased schedule nevertheless means only a fraction of the estimated total should be associated with the first implementation. Applying FTSE’s 10% initial factor to a $1.5 billion full-inclusion estimate suggests roughly $150 million of passive demand in the first tranche, although actual flows may differ because fund assets, prices, currencies and final constituent weights will change.
Another 20%, or approximately $300 million on the same simplified basis, could be associated with the March 2027 tranche. The two final stages could each represent about $525 million.
These figures illustrate the timing rather than provide precise trading forecasts. Some funds may pre-position, use derivatives or execute at different times, while other portfolios may track benchmarks that apply different mandates or implementation policies.
Reuters previously reported that passive inflows could reach approximately $1.5 billion through the full four-stage process. The broader total, including active allocations, has been estimated as high as $6 billion by some institutions, but those flows are discretionary and cannot be treated as guaranteed. Reuters
Global-broker reforms secured the upgrade
Vietnam’s promotion followed years of efforts to address barriers faced by foreign institutions, particularly settlement risk and the former requirement to deposit the entire value of a trade before execution.
FTSE confirmed the reclassification after its March 2026 interim assessment found sufficient progress in implementing the global-broker model. The arrangement allows foreign institutional investors to deal through global brokers with which they already maintain established counterparty relationships.
Circular 08/2026/TT-BTC created additional legal support for that model and strengthened Vietnam’s non-prefunding framework. FTSE said regulators, domestic brokers, global intermediaries, custodians and asset managers had aligned on key operational components, although bilateral broker agreements still needed to be completed.
These changes matter beyond index eligibility. Reducing the operational cost and counterparty risk of investing in Vietnam could encourage institutions to participate even when they do not passively follow an FTSE benchmark.
The World Bank estimates that emerging-market status could help generate $3 billion to $5 billion in portfolio flows over the first few years. It argues that the reforms can also deepen market liquidity and help Vietnamese companies access more long-term private financing, according to the World Bank.
Why active capital may arrive before passive funds
Passive inflows are relatively straightforward to estimate because they are linked to assets tracking an index and the weight assigned to Vietnam. Active capital is harder to forecast because managers retain discretion over whether, when and at what price to invest.
The August 21 list could nevertheless influence active portfolios in several ways.
Fund managers benchmarked against FTSE Emerging indices may buy prospective constituents before September to reduce the risk of becoming underweight when Vietnam enters the benchmark. Investors may also favor highly liquid stocks that are expected to receive repeated passive purchases across the four tranches.
At the same time, anticipation can push prices higher before the compulsory buying occurs. If valuations become excessive, active managers may choose to remain underweight despite the benchmark change.
The upgrade may also create selling pressure. Frontier-market funds will lose Vietnam exposure when the country is removed from FTSE’s frontier indices in September. Although the emerging-market asset pool is much larger, sales by frontier portfolios and purchases by emerging-market funds may not occur at identical times.
The net effect is expected to be positive over the full transition, but individual sessions could remain volatile.
The upgrade will not eliminate foreign-investor risks
FTSE inclusion improves Vietnam’s visibility and accessibility, but it does not remove the variables that determine international investment decisions.
Currency performance will be critical. Dollar-based investors can lose money even when Vietnamese share prices rise if the dong depreciates sufficiently against the US currency.
Valuation is another constraint. Global funds compare Vietnam with India, Indonesia, China, Malaysia and other emerging markets. Strong earnings growth can justify a premium, but expectations of index demand alone cannot sustain prices indefinitely.
Foreign ownership limits remain relevant, particularly in banking and other restricted sectors. A company may be large and profitable but receive a reduced index weight—or fail eligibility tests—if insufficient shares are available to international investors.
Corporate governance, English-language disclosure, settlement reliability and market liquidity will also determine whether active institutions build long-term positions rather than make short-term allocations around the index event.
These remaining obstacles explain why FTSE’s upgrade should be viewed as a structural opportunity rather than an automatic revaluation of every Vietnamese stock.
What investors should watch next
The August 21 announcement should be examined for three elements: the number of eligible companies, their investability weights and any differences from FTSE’s previous watch list.
Trading volumes and foreign net flows could increase as September approaches, especially among large-cap stocks with substantial projected index allocations. Investors should distinguish genuine long-term accumulation from short-lived positioning ahead of the rebalance.
The closing auction before the September 21 effective date could experience unusually large transactions as index funds align their portfolios. Increased volume does not necessarily indicate a change in a company’s fundamentals; it may reflect mechanical benchmark replication.
Progress on global-broker agreements and the performance of the non-prefunding system will be equally important. FTSE has reserved the right to evaluate index replication after each tranche before continuing the transition.
The August review will therefore answer the immediate question of which companies enter the indices. The larger test begins in September: whether Vietnam’s trading, settlement and foreign-access infrastructure can absorb global capital smoothly enough to complete all four stages by September 2027.
