Bank of Thailand governor said on Tuesday a rapid rise in the baht was not good for the country's economic recovery although it was not causing exports to decline.
Exports have faced several problems, including falling behind in technology innovation and a slow recovery in export markets, Bank of Thailand governor Veerathai Santiprabhob, told reporters.
But the baht's rapid appreciation in certain periods "is not conducive to the economic recovery and the central bank will closely monitor it," he said.
Baht's strength 'not good for economy
The baht was at 34.62 per dollar on Tuesday, hovering around its highest level in more than a year, driven by foreign fund inflows.
The currency has risen by 4% against the dollar this year, and Mr Veerathai said its strength was not greater than other regional currencies.
The central bank expects exports to fall for a fourth straight year in 2016.
