"We have not intervened in the baht value for a while," the bank's governor, Tarisa Watanagase, said in a report from the Thai News Agency. "Today, we cannot tell whether we will intervene to supervise the currency movement or not."

The baht is falling, but at a pace consistent with other regional currencies, the agency reported.

"We have our own ways to oversee the currency, but cannot tell in detail," Tarisa said.

On Friday, the baht was valued at 33.16 to a dollar.
