Bank of Thailand Governor Veerathai Santiprabhob also said the central bank had no policy to intervene in currency markets to gain an advantage in trade.

The central bank will only act to smooth any excessive moves in the baht, he told a business seminar.

The central bank has left its policy interest rate steady at 1.50 percent, near record lows, since April 2015.

But at the March 28 meeting, the vote to hold was 6-1, with the dissenting member voting for a hike.

It next reviews policy on May 16. Most analysts expect no policy change for the rest of 2018, though some predict rate increases in the second half of this year.
