Discuss how India's Unified Payments Interface (UPI) is emerging as a tool of digital diplomacy in South Asia and beyond. Illustrate with recent examples.

UPI, which had onboarded nearly 55.49 crore users by June 2026 [3], has outgrown its role as a domestic payment rail. India now exports it as Digital Public Infrastructure (DPI), converting a technology stack into an instrument of influence, goodwill and economic integration.

Anchoring the neighbourhood

• The Favara-UPI corridor, live since 30 July 2026, lets Maldivian users transfer funds in Rufiyaa for credit in rupees, initially through Bank of Maldives and Maldives Islamic Bank [1].
• Built by NIPL with the Maldives Monetary Authority after a July 2025 agreement, with QR-based merchant payments planned next [1].
• It complements the 2024 India-Maldives Joint Vision on economic partnership, currency swap support and local-currency settlement [2] — evidence that digital connectivity can stabilise a relationship after political friction.
• Similar linkages in Nepal, Bhutan and Sri Lanka extend the "Neighbourhood First" logic to everyday transactions [4].

Extending reach beyond South Asia

• The UPI-PayNow link with Singapore and acceptance in the UAE and Mauritius serve large Indian diaspora and worker populations [4].
• Entry into France marked UPI's first European foothold, projecting India as a standard-setter rather than a rule-taker [4].

Diplomatic dividends

• Cheaper, real-time remittances shift flows from informal channels to regulated ones, deepening financial inclusion [1].
• Rupee-denominated settlement supports internationalisation of the INR and reduces dollar dependence.
• DPI offered as a global public good builds soft power in the Indian Ocean Region, where strategic competition is sharpening.

Constraints remain: most corridors are currently one-directional and person-to-person, adoption depends on partner regulators and banks, and cross-border data and settlement norms are still evolving [1].

UPI thus links technological capability to diplomatic purpose. Widening corridors to two-way merchant payments, pairing them with RuPay acceptance and local-currency trade settlement, would turn a payments network into durable regional public infrastructure — advancing both India's economic interests and its SAGAR vision of shared regional growth.
