Regulatory sandboxes have become a central policy tool for supporting fintech innovation while managing risks. This article compares the economic effects of sandbox programs in Japan, Singapore, and the United Kingdom, focusing on how sandboxes affect firm financing, product development, market entry costs, and regulator learning. Drawing on global surveys, country descriptions and empirical work, the paper shows that sandboxes can shorten time-to-market for new products, raise follow-on investment for participating firms, and produce regulatory knowledge that reduces later compliance costs – yet they also concentrate selection effects, create potential competitive distortions, and require careful exit strategies to deliver net public benefit. The comparative evidence suggests that well-designed sandboxes – which combine clear eligibility rules, time-limited testing, consumer safeguards and pathways to authorization – produce positive economic returns, especially when embedded in a broader, coordinated policy framework.
