It's not the best but way better than 0.4-0.5% from a savings account. I get 1.85% for a 7 months term at Bangkok Bank which is better than a 12 months term. I got 2.10% a year ago. I earn a total of about 22k baht per year from interest. (I have three accounts at the moment.) Not a fortune but I'm not complaining. It's just money. 😎
So you don't consider for example Nakhon Si Thammarat being out in the sticks way down south? I do. But of course you need to ask the immigration office where you're staying. That's a given. I did that when I opened my first FDA.
Well, every retiree here doesn't stay out in the sticks in Isaan. I don't have to ask "my" immigration office about it because I already have my money in an FDA.
