Thailand's economy slowed slightly in the first quarter ahead of impending U.S. tariff hikes that have cast uncertainty over the outlook, prompting officials to downgrade their growth forecast for the year ahead.

Gross domestic product rose 3.1% from a year earlier, the Office of the National Economic and Social Development Council said Monday.

That compared with a revised 3.3% expansion in the fourth quarter and the 2.8% growth forecast by 13 economists in a Wall Street Journal poll.

On a seasonally adjusted quarterly basis, the economy grew 0.7% in the first three months of the year, up from 0.4% in the fourth quarter, the data showed.

Thai officials now expect the economy to grow 1.3% to 2.3% in 2025, down from the earlier forecast of 2.3% to 3.3%. That compares with growth of 2.5% seen in 2024.

Monday's data release follows the Bank of Thailand's decision to cut rates again in April amid rising global uncertainty.

The central bank said at its April meeting that the economy will likely grow more slowly than previously expected, citing risks from trade policy uncertainty and a decline in tourism.
