It is my opinion, that Thailand has not, and will not raise Interest rates any time soon.
They will just let the people suffer with the increased Inflation.
The Government essentially is terrified of the backlash that this would cause throughout Thai Society.
House prices / Building costs are set to rise by some 5 % or so ( more like 10 % ), and this means Developers will incur additional charges on any Money borrowed from the Banks Etc, along with being burdened with Property they have less chance of selling due to increased Mortgage Rates and diminished demand.
The property Market has been on its rear end now for some Years, and any increase in Interest Rates would be a major issue in the loss of Revenue stream for the Government, and with Household Debt at record levels of near 100 % of GDP, any increase would push many more people over the edge into default on their Loans.
Either way the Government play the issue of inflation, they are running the risk of riots on the streets again, and this is something they desperately have to avoid to help the Tourism sector recover.
