How much money do I need to show at Thai immigration?

When entering Thailand, it's generally recommended to have at least 20,000 Thai Baht (or equivalent in other currencies) on hand as proof of funds, although many travelers report never being asked to show this amount. For visa exemption entries, having 10,000 Baht per person is suggested. Most travelers find that while the requirement exists, it is rarely enforced unless there are additional concerns such as frequent entries or visa extensions.
