The Democratic Sweep is a VN-Index Catalyst

The Democratic Party’s U.S. midterm sweep should act as a stronger catalyst for Vietnam’s stock market than for its economy by reducing tariff fears and improving the outlook for domestic interest rates.

• Vietnam’s GDP grew 9% in the first nine months of 2026, while 2026 earnings are expected to rise 25%, yet the VN-Index has remained broadly flat because of tariff concerns and elevated domestic interest rates.
• Vietnam’s exports to the United States increased 26% this year, high-tech exports rose by more than 50% year on year, and the bilateral trade surplus reached the equivalent of 30% of GDP.
• The Economist Intelligence Unit estimates that Vietnam’s effective average U.S. tariff is below 10% because exemptions and carve-outs limit the practical impact of headline tariff proposals.
• Vietnamese inflation is slightly above 5%, with roughly 3 percentage points attributed directly to war-related price increases, while lower oil prices and an easing loan-to-deposit ratio could support lower domestic interest rates.
• Export growth is likely to slow in 2027 because foreign-invested firms’ new export orders peaked in July and their imports of production inputs have declined after Vietnam’s trade deficit reached 7% of GDP around midyear.

Takeaway: Lower tariff risk, a possible end to the U.S.-Iran war and easing banking pressure could lift the VN-Index in the coming months, with the forward PEG ratio below 1x based on 12% expected earnings growth in 2027, although the economic boost should remain modest.
