Taiwan is among the world’s first countries to implement financial regulatory sandbox by legislation. The proposed FinTech Innovation Experimentation Bill is now being reviewed by the Legislative Yuan, and is expected to have significant impact on the country’s financial market and FinTech ecosystem. The Bill focuses mainly on how to conduct the experimentation per se rather than on how to enable the sandbox entity to continue to engage in the tested innovative activity/business after the experimentation is completed and proved to be successful. This paper reviews the post-experimentation arrangement set forth by the Bill, and argues the need for implementing a tiered licensing regime, and for different approaches by financial institutions and FinTech firms to bringing their innovation to life. This paper further proposes to redesign the post-experimentation phase, and suggests necessary amendments to the Bill.
