Depreciation and Overvaluation of the Vietnamese Dong Lead to the Largest Foreign Capital Sell-off in Vietnam's Stock Market History
```
Due to increasing pressure from currency depreciation and profit-taking triggered by overvaluation in the stock market, foreign investors are withdrawing from Vietnam's stock market at an unprecedented pace, causing the market to experience the largest single-month capital outflow on record.
Global funds made net sales of $1.5 billion worth of local stocks from Vietnam's market in August, the largest single-month outflow since data records began in 2009. This large-scale divestment comes as the Vietnamese dong hits a record low against the US dollar, with some analysts predicting further weakening.
This wave of selling has put pressure on Vietnam’s stock market, which has outperformed its Southeast Asian peers this year. Vietnam’s benchmark VN Index resumed trading on Wednesday after a two-day holiday, dropping as much as 0.7%. Bearish sentiment in the currency market persisted, with the dong continuing to fall against the dollar that day.

Tyler Manh Dung Nguyen, chief market strategist at Ho Chi Minh City Securities Corporation, said that “concerns about unfavorable exchange rate prospects” are one reason behind the capital outflow, while the previous sharp rally in the market also triggered profit-taking.
Record Capital Outflows Intensify Depreciation Pressure
Data shows that August’s net outflow of $1.5 billion set a new record for Vietnam’s stock market. Notably, part of the outflow was concentrated in key stocks. Analyst Sufianti pointed out that last month, conglomerate Vingroup saw a net outflow of about VND 13 trillion (approximately $493 million), accounting for a significant portion of the total outflow.
However, Sufianti also added that capital outflow is not unique to Vietnam. “Most emerging markets have also seen capital outflows, so this does not appear to be a country-specific issue,” she said.
The exchange rate issue is at the core of current investor concerns. So far this year, the Vietnamese dong has depreciated about 3.4% against the US dollar, making it the worst-performing Southeast Asian currency. Analysts predict that due to rising import demand and a narrowing current account surplus, the dong will face further depreciation pressure.
Mitsubishi UFJ Financial Group (MUFG Bank) forecasts that by the end of this year, the dong may fall to 26,500 per US dollar. In Wednesday’s trading, the dong continued its weakness against the dollar.

Before the sell-off, Vietnam’s stock market experienced a strong rally. Driven by economic growth and expectations of a potential upgrade in market status, the VN Index has surged more than 32% so far this year, outperforming most Southeast Asian markets. However, this rebound also pushed valuations higher, creating conditions for foreign investors to lock in profits and seek exits.
Despite the large-scale withdrawal of foreign capital, the market isn’t entirely unsupported. Nguyen Anh Duc, head of institutional brokerage at SBB Securities, believes that Vietnam’s stock market is supported by “resilient domestic capital flows.” In addition, he noted that continuously improving corporate earnings should provide solid fundamental support for the market, which may help cushion the impact of foreign capital outflows.
