Overview of Banks in Thailand

For the next 12-18 months, Moody’s Investors Service gives a stable outlook to banks in Thailand. The ratings agency’s outlook can be attributed to the improvement of the banks’ operating environment, as well as the strong capitalization and loan loss reserve coverage. However, the banking sector will be affected by weak private sector investment, political uncertainty and high level of household leverage.
