Vietnam FTSE Upgrade: VHM Leads Foreign Buying as $2.28B Inflow Nears

Overview

FTSE Russell will formally upgrade Vietnam’s stock market to Secondary Emerging Market status on September 21, a reclassification SSI Research expects to pull roughly USD 2.28 billion in passive inflows under its base case. The flow is phased rather than immediate, and the near-term picture remains mixed: foreign investors have net sold about VND 93,600 billion year-to-date, but bought Vinhomes (VHM), MCH and FPT in the latest week while selling VCB, HPG and DXG, according to MBS Securities.

Key Facts

• FTSE Russell confirms Vietnam’s upgrade to Secondary Emerging Market on September 21, with index inclusion flows beginning afterward.
• SSI Research base case: about USD 2.28 billion in passive inflows, based on Vietnam’s weight of roughly 0.49% in the FTSE Emerging All Cap Index.
• First tranche in September 2026 equals only 10%, or about USD 228 million; the remaining USD 2.05 billion is scheduled across March, June and September 2027.
• Bull case: if Vietnam’s weight rises to 0.95% by September 2027, passive inflows could reach USD 4.45 billion.
• Foreign investors net sold about VND 93,600 billion year-to-date, but August net selling fell 88.6% month-on-month to VND 1,400 billion, the lowest in five months.
• August market turnover averaged VND 18,700 billion per session, below the VND 26,900 billion average for the first eight months and VND 28,900 billion in 2025.
• MBS reported VND 1,446 billion of net foreign selling in the latest week, with net buys in VHM, MCH and FPT against net sells in VCB, HPG and DXG.

What Happened

SSI Research data shows the improvement in foreign flows came mainly from weaker selling rather than stronger demand. Total August sell value fell 22% month-on-month to VND 41,700 billion, while buy value held near VND 40,400 billion. That narrowing gap, not a surge in buying, explains the smaller net outflow.

The structural story is the FTSE reclassification itself. Vietnam’s weight in the FTSE Emerging All Cap Index rose from about 0.34-0.35% in March to 0.49-0.50% in August. MBS notes that frontier-market ETFs tracking the old classification may need to finish selling Vietnamese holdings before the switch, while emerging-market funds deploy only about 10% in 2026. The result, per MBS, is a “sell once, buy in many tranches” pattern that can keep technical supply pressing on the market in the short term.

Market Context

Vinhomes (VHM) trades on HOSE and closed at VND 73,100 on September 10, 2026. The stock was among the names foreign investors bought on a net basis in the latest week, alongside MCH (VND 142,000) and FPT (VND 74,500), while VCB (VND 59,000), HPG and DXG were sold. The divergence matters because it shows foreign money is rotating selectively rather than exiting broadly. Market-wide, August turnover of VND 18,700 billion per session is well below the 2025 average, indicating the recent rebound rests on fading sell pressure rather than decisive domestic demand.

Strategic Significance

For long-term investors, the upgrade changes the buyer base rather than the near-term flow. Once Vietnam sits inside FTSE emerging-market benchmarks, index-tracking capital becomes a structural, recurring source of demand tied to weight changes, not sentiment. The phased schedule, however, means the market must absorb frontier-fund supply with domestic money first. Real estate names such as VHM, which already appear on foreign buy lists, are positioned to benefit if index funds build positions early, but the thesis depends on earnings and liquidity recovering enough to absorb the transition supply.

What to Watch

• FTSE Russell’s official September 21 announcement and any confirmation of index weight and transition timeline.
• Monthly foreign net flow data from SSI Research and MBS for September and October, to see whether August’s slower selling persists.
• Daily market turnover versus the VND 18,700 billion August average, as a gauge of domestic absorption capacity.
• Foreign ownership room and ETF rebalancing filings for VHM, FPT, MCH, VCB, HPG and DXG.
• Any revision to SSI’s USD 2.28 billion base-case estimate if Vietnam’s index weight moves toward the 0.95% bull-case level.
