Few could have predicted that a domestic payment platform UPI (Unified Payments Interface) would become one of India’s key strategic tools for shaping its digital and economic influence worldwide.

As CNBC’s Inside India newsletter highlights, UPI’s global expansion is more than a convenience for Indian travelers; it’s part of a broader economic and technological strategy one aimed at exporting indigenous innovation and strengthening India’s digital sovereignty.

Let’s explore how this transformation happened, why it matters, and what lessons other emerging economies including Vietnam can learn from India’s playbook.

A Solid Foundation: UPI at Home

Before going global, UPI built an unparalleled foundation domestically.

• According to the Reserve Bank of India (RBI), UPI accounts for nearly 85% of all digital payment volumes in the country.

• The system processes tens of billions of transactions each month, demonstrating its stability and scalability.

• More importantly, UPI is part of India’s Digital Public Infrastructure (DPI) a set of open, interoperable, low-cost systems that include Aadhaar (digital ID) and RuPay (domestic card network). Together, they form the “India Stack,” a model admired globally for enabling financial inclusion and innovation at scale.

This domestic success created the credibility and technical maturity necessary for India to “export” UPI as infrastructure, not just as a payment app.

The Global Rollout: Key Milestones

India has methodically signed agreements and partnerships to expand UPI’s reach.

Japan: The East Asian Breakthrough

In October 2025, NPCI International Payments (NIPL) signed an MoU with NTT DATA to enable UPI acceptance at merchants across Japan — allowing Indian visitors to scan UPI QR codes and pay instantly in rupees. This marks a strategic step toward deeper fintech cooperation in East Asia.

Middle East and Qatar

Qatar recently became the latest country to join the UPI acceptance network, following a similar rollout in the UAE, where NIPL partnered with Magnati and Network International to enable UPI QR at retail stores, restaurants, and tourist destinations — letting Indian travelers “pay like at home.”

Singapore: Real-Time Cross-Border Linkage

The UPI–PayNow linkage between RBI and Singapore’s MAS has become a global model for instant, low-cost cross-border payments. It connects users’ mobile numbers directly to their accounts, cutting remittance time from days to seconds.

Beyond Asia

• India is negotiating with African and Latin American nations (including Namibia and Peru) to build “UPI-like” real-time payment systems, effectively exporting the architecture rather than just the brand.

• Meanwhile, PayPal is exploring linking its cross-border platform with UPI, signaling that global fintech giants view India’s framework as a future-ready standard.

UPI as an Instrument of Economic and Geopolitical Strategy

Why is India investing so heavily in exporting UPI? Three strategic motives stand out:

Real Economic Impact: Tourism, Trade, and Remittances

For the 30-plus million Indians who travel or work abroad, being able to use UPI reduces friction — no card fees, no currency-exchange hassle. This not only boosts outbound spending but also encourages inbound acceptance of Indian payment flows, strengthening trade and remittance efficiency.

Exporting Digital Infrastructure

UPI represents a blueprint for digital public infrastructure: APIs, authentication standards, QR formats, settlement layers, and data-security protocols. By helping other nations replicate or connect to it, India effectively exports know-how, governance models, and technical standards, gaining soft power through technology.

Setting Global Standards (“Standards Power”)

Control of standards not hardware defines influence in the digital economy. If UPI becomes a globally recognized or interoperable protocol, India gains a permanent seat at the table in defining how real-time payments operate across borders.

The Challenges Ahead

While the potential is vast, UPI’s international journey faces complex obstacles.

Legal and Data-Governance Barriers

Each jurisdiction has unique rules around data privacy, localization, anti-money-laundering (AML), and know-your-customer (KYC) requirements. Cross-border payment data sharing requires bilateral trust and clear security frameworks.

Currency Conversion and Settlement Costs

Even if QR payments are instant, the FX conversion and settlement layers can be expensive. Unless India and its partners create cost-effective clearing mechanisms, merchants may hesitate to adopt.

Competing Systems

Many countries already have domestic RTP networks — Thailand’s PromptPay, Brazil’s PIX, Malaysia’s DuitNow, etc. UPI’s success depends on interoperability and partnership, not replacement.

User Experience and Local Trust

Adoption hinges on clarity, transparency, and ease of use. If foreign users or merchants find UPI complex or unfamiliar, adoption will lag despite strong technical performance.

The evolution of UPI from a national digital payment solution to a strategic export illustrates how a developing nation can turn indigenous innovation into global economic leverage.

UPI is more than an app. It is an infrastructure, a philosophy, and a symbol of India’s belief in open, inclusive technology.

If India continues balancing regulation, security, and interoperability, UPI could emerge as a global payment standard transforming India’s position from user of technology to architect of the digital future.
