With my U.S. bank, you update your address in the app from your recliner.
Dear Bangkok Bank, if your app is secure enough to transfer all your money out of your account, why isn’t it secure enough to update your mailing address?
Using a dedicated, interest bearing fixed deposit account is a no brainer. Yes it’s just 2%, but that helps lessen the pain of 7% inflation slightly.
Protip #1: Open the new bank accounts before you close the existing account. Fund the account so the balances overlap by a few business days.
Protip #2: life is too short to fight bureaucrats. Hire a respected agent. In CM, this means one trip to the bank with the agent to flash my passport and bank book, and a second 3-5 minute appointment at immigration to sit for a photograph.
