Despite domestic fintech success via UPI, cross-border payments suffer from delays and lack of transparency. The RBI's directive to expedite inward remittances is a crucial policy corrective, addressing the "final domestic leg" bottleneck. While complex, an interoperable financial system is an economic imperative. Fragmentation, though, risks isolating new payment systems and reducing global GDP. The solution lies in ensuring innovation remains connected and standardized, fostering secure, effective communication between diverse financial protocols. India's progress shows how infrastructure, regulation, and entrepreneurship can transform finance, making speed and safety coexist globally.
