One key component of Thailand’s support for the development of fintech innovations is its sandbox framework, supervised by the Bank of Thailand (BOT). This framework supports business operators in experimenting with new technologies under controlled conditions. This article explores the structure and significance of the BOT’s sandbox program in driving fintech innovation in Thailand.

Own Sandbox The Own Sandbox is an optional program that the BOT encourages for financial service providers and fintech operators implementing new technologies. This sandbox provides a more flexible environment for testing innovations that may not require the same level of regulatory scrutiny as those in the Regulatory Sandbox. Enhanced Regulatory
