Thailand's banks only forsee a small impact from the troubles facing Credit Suisse and some banks in the United States due to their low external exposures and strong capital positions, the country's banking group said on Thursday.

Thai lenders had worked closely with the central bank on supervision to strengthen their positions, Kobsak Duangdee, secretary general of the Thai Bankers' Association, told reporters.

"They don't have large overseas borrowing and their investment with those troubled banks is not much. So, an indirect impact is not big," he added.

On Wednesday, Finance Minister Arkhom Termpittayapaisith said there had been no impact on Thailand so far from the U.S. bank problems and that the government was ready to act should there be any impact on the country from the volatility.
