TAIPEI (Taiwan News) — Taiwan’s consumer prices rose in April, driven by higher fuel and transport costs following a surge in international oil prices linked to the Iran War.

The Directorate-General of Budget, Accounting and Statistics announced Thursday that the consumer price index rose 1.74% year-over-year in April, per CNA. This marked a sharp increase from March’s 1.2%, with fuel costs jumping 13.6%.

Transportation and communications recorded the largest increase among the seven main CPI categories, rising 2.66% from a year earlier. Higher fuel prices, train fares, and airline tickets all contributed to the increase.

Core CPI, which excludes fruit, vegetables, and energy, rose 1.91% year-over-year, slightly lower than March’s 1.94%, CNA reported. Meanwhile, the CPI for key household necessities rose 1% in April, a smaller increase than in March.
