Vietnam’s consumer price index (CPI) rose 0.62% in September from the previous month, bringing the index up 4.20% from December 2025 and 5.08% year on year, according the data release by the National Statistics Office on October 3.
Nine of the 11 major groups of consumer goods and services recorded price increases, while two groups saw declines.
Transport recorded the largest increase, rising 3.97% and contributing 0.40 percentage points to the overall CPI increase. Domestic petrol prices rose 9.39%, while diesel prices increased 4.53%, largely reflecting movements in global fuel markets.
Education prices rose 1.41%, contributing 0.08 percentage points to overall CPI growth. Education service prices increased 1.60%, while demand for textbooks, stationery and school supplies also rose at the beginning of the new academic year.
Food and catering services increased 0.19%, contributing 0.07 percentage points, as food prices rose 0.27% and rice and other staple food prices increased 0.11%.
Housing, electricity, water, fuel and construction materials rose 0.28%, driven by higher kerosene, gas and rental prices. Electricity prices, however, fell 0.13% amid lower consumption during the rainy and stormy period.
Meanwhile, culture, entertainment and tourism prices fell 0.28%, while information and communications prices declined 0.14%.
Average CPI in the third quarter increased 4.80% year on year. For the first nine months, average CPI rose 4.52%.
Core inflation increased 0.11% month on month in September and 4.45% year on year. Average core inflation for the first nine months rose 4.26%, below headline CPI growth, partly because volatile items such as fuel, gas, food and fresh produce, and healthcare services are excluded from the core inflation calculation.
