BOT deputy governor Krirk Vanikkul said on Monday that such concerns are however serving as a warning to all that they should be cautious in spending.
He also insisted that financial institutions stand ready to amend their business strategies to cope with a sudden change of tide. Commercial banks have recently strengthened the requirements for the extension of mortgage loans for the purchases of the third houses.
At present, the commercial bank sector's NPLs stood at 2.5 per cent of outstanding loans.
"Though households' ability to repay declines, the NPLs haven't yet surged," he said.
