FTSE Russell has officially reclassified the Vietnamese stock market from frontier market status to secondary emerging market status, effective from September 21, and has initiated a phased inclusion in its global equity index series.

The full transition will extend through September 2027, with market institutions projecting that combined passive index funds and active allocation capital could bring as much as $6 billion in net new inflows to Vietnam's equity market.

The first tranche accounts for 10% of the final investable weight, with the entire Vietnamese stock inclusion scheduled to complete in four stages over one year.

Starting from the opening of trading on September 21, Vietnamese equities will enter the FTSE Global Equity Index Series and related indices. Existing Vietnamese constituents will be removed from the FTSE Frontier Market Index in a single step, while the inclusion into the emerging market index will proceed in four stages to mitigate the impact of concentrated rebalancing on liquidity and trade settlement.

The initial phase is set for September 2026, incorporating 10% of the final investable weight. A further 20% will be added in March 2027, bringing the cumulative total to 30%. Additional increments of 35% are scheduled for June and September of that year respectively, completing the full weight allocation.

Following each adjustment round, FTSE Russell will assess whether index funds can smoothly replicate the benchmark changes before deciding whether to proceed with the next phase as originally planned.

A qualified list of 27 Vietnamese stocks

Based on data as of June 30, a total of 27 Vietnamese stocks have successfully passed the size, liquidity, and investability screening under the FTSE Global All-Cap Index. The list includes Vietcombank, Vingroup, Vinhomes, BIDV, Hoa Phat Group, VPBank, FPT, Masan Group, Vietjet Air, and Vinamilk, spanning sectors such as banking, real estate, industrials, technology, consumer goods, and aviation.

Based on closing prices as of August 21, Vietnamese equities are expected to represent approximately 0.031% of the FTSE Emerging Markets Index after the initial phase, with the weight projected to rise to about 0.309% once all four stages are completed. Within the FTSE Emerging All-Cap Index, the weight will gradually increase from roughly 0.049% to approximately 0.488%.

Index weight allocation generates sustained rebalancing demand

Following the effective inclusion, funds tracking the FTSE Emerging Markets and global equity indices will be required to allocate Vietnamese stocks according to the new weights. Since the adjustment is spread across four rounds, related buying activity will shift from a one-time concentrated inflow to a portfolio rebalancing process lasting approximately one year.

The projection of up to $6 billion in inflows encompasses both passive index capital and active funds that may increase allocations in response to the market upgrade. The actual scale depends on fund tracking scope, the free-float ratio of Vietnamese stocks, foreign ownership headroom, and subsequent market price movements.

The direct conditions enabling this upgrade include Vietnam's recent improvements to foreign institutional trading mechanisms, such as introducing a non-prefunding trading framework, establishing trade failure handling procedures, and advancing foreign institutions' access to the local market through global brokers.

FTSE Russell will continue applying foreign ownership limit screening to Vietnamese constituents, and stocks that fail to maintain liquidity or investability requirements may be removed in subsequent reviews.
