Vietnam’s Growth Slows as Energy Costs Rise

Vietnam’s economy lost some momentum in the first quarter

Vietnam’s economy started 2026 with strong but slower growth than at the end of last year, as rising energy costs and broader external uncertainty weighed on the outlook. According to the latest data, GDP expanded 7.83% year on year in the first quarter, down from 8.46% in the fourth quarter of 2025. The slowdown still leaves Vietnam among the faster-growing economies in the region, but the loss of momentum matters because it arrives just as the country is trying to pursue a far more ambitious growth trajectory for 2026.

The shift is especially notable against earlier expectations. Official planning had previously pointed to an exceptionally high growth ambition for 2026, while Bloomberg reported at the end of March that Hanoi’s push for rapid economic expansion and industrial upgrading was being tested by the Iran-linked fuel shock and the rising cost of energy inputs.

Higher energy prices are feeding inflation

The most immediate pressure point has been energy. Bloomberg reported that Vietnam’s two domestic refineries cover about 70% of the country’s fuel demand, but much of the crude they process comes from the Middle East, especially Kuwait. That leaves the economy exposed not only to higher oil prices but also to any disruption in supply flows and shipping.

Inflation has already responded. Data aggregating official statistics show Vietnam’s annual inflation rate accelerated to 4.65% in March 2026 from 3.35% in February, the highest reading since January 2023. The consumer price index also rose to 106.82 points in March from 105.52 in February. For an economy trying to preserve domestic demand, export competitiveness and investor confidence at the same time, that is a more difficult macro combination.

Why the energy channel matters so much

Vietnam’s vulnerability is tied to its growth model. The economy remains deeply integrated into manufacturing and export supply chains, making it especially sensitive to fuel prices, shipping costs, electricity expenses and imported raw materials. Bloomberg said Vietnamese leaders had already reached out to counterparts in Japan, South Korea, Algeria and Angola to help shore up supplies, warning that the country could face difficulties if the disruption continued through April.

That makes the energy shock more than an inflation story. It is also a margin story for industry. Vietnam has benefited in recent years from manufacturing relocation, electronics expansion and export-assembly growth, but that model is highly exposed to any rise in transport, power and imported fuel costs. The risk is becoming more visible just as policymakers try to move the economy beyond low-cost manufacturing toward a more technology-driven growth path.

Industry and exports are still holding up

Even so, the economy is not yet showing signs of a broad reversal or sector-wide collapse. The first-quarter data indicate that growth remained broad-based: industry and construction expanded 8.92%, services rose 8.18%, and agriculture grew 3.58%. That suggests the slowdown is a cooling in momentum rather than a breakdown in the model.

Some export segments are also still showing resilience. Vietnam News reported in early April that the agricultural sector maintained export growth in the first quarter, even though falling prices for several key commodities were weakening the quality of that expansion. That matters because external trade remains one of the main supports for overall Vietnamese growth.

The fast-growth target is becoming harder to reach

For Vietnam’s economic leadership, the key question is now less whether growth continues and more whether it can stay near the government’s stated ambitions. Official planning had earlier aimed at a growth target around 10% for 2026, far above most outside forecasts. But external projections are already more cautious. The Vietnamese government’s official information channel reported that UOB had raised its 2026 Vietnam growth forecast to 7.5%, and even that improved estimate remains well below the domestic target.

That is why the 7.83% first-quarter figure cuts both ways. On one hand, it remains one of the stronger growth rates in the region. On the other, it is already a slowdown at the start of the year, arriving alongside an energy shock, firmer inflation and a more fragile external environment. In that sense, even a strong headline figure begins to read as a warning that the path ahead is getting tougher.

Uncertainty is arriving through global channels as well

Vietnam’s challenge is broader than domestic fuel pricing alone. The energy shock has landed at a time of wider global trade and geopolitical stress. Bloomberg reported in January that the economy had ended 2025 with stronger-than-expected growth thanks to manufacturing, investment and trade even in the face of tariff-related headwinds. The latest shock makes that balancing act harder: growth remains high, but the margin for error is narrowing because new external disruptions pass more quickly into prices, production costs and business expectations.

That matters especially for a country that depends both on imported fuel and on the confidence of international manufacturers. For foreign investors, Vietnam still looks like a strong industrial platform, but rising energy costs increase the importance of supply resilience, energy infrastructure and the government’s ability to smooth fuel shocks quickly. That shift changes the conversation for both the real economy and for new investment decisions.

As International Investment experts report, Vietnam’s first-quarter slowdown in 2026 does not yet amount to a crisis, but it does show how vulnerable even a fast-growing manufacturing economy remains to an external energy shock. If fuel pressure persists, the main risk for the country will not be a sudden collapse in growth but a slower, more difficult combination of higher inflation, weaker industrial margins and a tougher path toward its ambitious 2026 targets. If policymakers succeed in stabilising supply and containing prices, Vietnam can still remain one of Asia’s most resilient markets, but on a much more expensive energy base.
