Vietnam's VN-Index Crashes Over 100 Points in Historic Single-Day Plunge as Middle East War Sparks Asia-Wide Sell-Off

Just 15 minutes into the morning session on March 9, the VN-Index plunged over 100 points, hitting a low of 1,663 before closing near 1,653 — a single-day drop of more than 6%.

It was the first time in history that the VN-Index fell more than 100 points in a single session.

And this wasn't even the first day of losses.
Last week (March 2–6), the VN-Index had already shed about 112 points — nearly 6% — sliding from around 1,880 to 1,768.
Including today's crash, the index has lost over 220 points in just six trading days.

What Happened?

The trigger was a rapid escalation of the Middle East conflict.

In early March, military clashes between the US-Israel coalition and Iran intensified. Iran's Revolutionary Guard Corps declared the Strait of Hormuz closed. Iran's government later denied a "complete blockade" on March 6, but by then hundreds of ships were already stranded and several major international maritime insurers had canceled war risk coverage for the region starting March 5.

About one-quarter of the world's oil and one-fifth of its liquefied natural gas pass through the Strait of Hormuz.
Any disruption there immediately sends shockwaves through global energy supply chains.

Brent crude surged to USD 118 per barrel on March 9, up roughly 30% in a single week.

It Wasn't Just Vietnam — All of Asia Was Selling

The sell-off was an Asia-wide phenomenon.

South Korea's KOSPI plunged more than 8%, forcing the exchange to activate its circuit breaker and halt trading for 20 minutes.
It was Korea's second circuit breaker in four trading days.
Samsung Electronics fell over 13% for the week, and SK Hynix dropped nearly 13%.

Japan's Nikkei 225 dove over 7% intraday before closing down about 5.5%, breaking below the 53,000 level.

Vietnam's decline wasn't the deepest among major Asian markets, but since it lacks an automatic circuit breaker mechanism (individual stocks have a 7% daily limit), panic selling was reflected directly in prices.

18 Out of 21 Sectors Fell

The board was almost entirely red.

Banking stocks hit the floor across the board: ACB, BID, CTG, HDB, SHB, TCB, VPB, and TPB all touched their daily lower limits.
Vingroup-linked stocks fared no better — VIC, VHM, VRE, and VPL all hit the floor.
Tech stocks dropped nearly 12%, retail fell over 10%, and real estate slid close to 9.5%.

The few bright spots were oil and gas and fertilizer stocks.
Oil and gas stocks rose over 8% as a group, fertilizer stocks climbed more than 11%, and individual names like DPM, DCM, and LAS gained 4–5%.

Why Did It Fall So Fast?

Beyond geopolitical panic, margin calls were the key accelerator.

When stock prices drop rapidly, brokerages and informal lenders demand investors top up their margin deposits.
If investors can't meet the call in time, the system automatically force-sells their holdings.
This chain reaction dragged the VN-Index down 100 points within the first 15 minutes of trading.

SSI Securities chairman Nguyễn Duy Hưng questioned the panic on his personal Facebook page: "Does the Vietnamese stock market really need to panic this much just because oil prices rose due to the Iran conflict?"

He argued that many stocks had already fallen to extremely low valuations.

What Comes Next?

VNDirect Securities laid out two scenarios in early March:

In the first scenario, tensions cool within weeks and don't escalate into a full regional war.
If that happens, market sentiment would gradually recover. Investors would shift focus back to domestic fundamentals — AGM season, corporate business plans for 2026, Q1 macro data, and FTSE Russell's March interim review of Vietnam's market upgrade.
Under this scenario, VNDirect estimates the VN-Index could retest 1,900 by late Q1 or early Q2.

In the second scenario, the conflict escalates into a full-blown regional war, keeping oil prices above USD 100 for an extended period.
That would hit global growth and push inflation back up, creating sustained downward pressure on Vietnam's stock market.

VNDirect also noted that historically, sell-offs triggered by geopolitical events tend to be short-lived and rarely turn into prolonged bear markets.

The FTSE Russell Upgrade Review Is a Wild Card

FTSE Russell is expected to conduct an interim assessment of Vietnam's market upgrade in March 2026.

Vietnam was confirmed for reclassification from Frontier to Secondary Emerging market status following FTSE Russell's September 2025 review, with an effective date of September 2026.
The March interim review will assess progress on direct market access for global brokerages.

If the review goes smoothly, FTSE estimates around USD 6 billion in passive fund inflows. The World Bank projects about USD 5 billion in the short term, with long-term potential reaching USD 25 billion by 2030.

This long-term positive catalyst is currently buried under geopolitical risk. But once tensions ease, it could become a powerful driver for a market rebound.

For Those With Investments in Vietnam

In the short term, volatility is extreme and uncertainty is high.

Oil price movements depend on the Middle East situation, which changes by the day.
The chain effects of margin calls may not be fully absorbed yet.

But if your investment horizon is longer, this may be the time to start watching for fundamentally strong stocks that have been caught in the indiscriminate sell-off.
The SSI chairman's view — that many stocks have fallen to very low valuations — represents at least one camp of market participants.

That said, until the situation clears up, managing leverage matters far more than trying to call the bottom.
