When India’s Unified Payments Interface launched in 2016, it was designed to solve a domestic problem — making digital payments accessible to hundreds of millions of Indians through a simple, interoperable, real-time system. It succeeded beyond most projections.

Now UPI is going international. And the ambitions behind that expansion say a great deal about where Indian fintech is heading.

Where UPI Works Internationally Today

As of early 2026, UPI-based payments are accepted in several countries through bilateral arrangements:

Singapore. The UPI-PayNow linkage, operational since February 2023, allows real-time transfers between Indian and Singaporean bank accounts. Indian travellers can scan PayNow QR codes in Singapore, and Singaporean residents can transfer money to Indian accounts instantly.

UAE. UPI acceptance at merchant terminals in the UAE went live in mid-2023, primarily targeting the large Indian expatriate and tourist population. Remittances using UPI infrastructure are being piloted.

France. The NPCI International partnership with Lyra Network enables UPI payments at select merchant locations in France, focused on tourist corridors.

Sri Lanka, Bhutan, Nepal, and Mauritius. RuPay card acceptance and limited UPI QR-based payments are operational in these markets, reflecting India’s neighbourhood-first strategy for payments diplomacy.

Japan and South Korea. Merchant QR code acceptance is being rolled out at tourist-heavy locations.

The pattern is clear: NPCI International is prioritising corridors where Indian travellers and diaspora populations create immediate demand. The strategy is pragmatic rather than aspirational.

The Strategic Logic

India’s push to internationalise UPI serves multiple overlapping objectives.

Remittance costs. India receives more remittances than any other country — approximately $125 billion annually. Traditional remittance channels charge 3-7% in fees. UPI-based cross-border transfers, once fully operational, could reduce this to under 1%. Even a partial shift would save Indian families billions of rupees annually.

Payments diplomacy. Exporting UPI is a form of soft power. When another country adopts Indian payments infrastructure, it creates technology dependence, commercial relationships, and diplomatic leverage. India is competing with China’s Alipay and WeChat Pay for influence in emerging market payment systems.

Trade facilitation. Real-time, low-cost cross-border payments reduce friction in bilateral trade, particularly for small businesses that find traditional trade finance expensive and slow.

Standard-setting. If UPI becomes the template for real-time payment systems in multiple countries, Indian fintech companies gain a natural advantage in those markets. They already understand the protocols, the architecture, and the regulatory patterns.

What’s Working

Merchant payments by Indian travellers. The most straightforward use case — an Indian tourist scanning a QR code abroad and paying in rupees while the merchant receives local currency — works well where it’s deployed. The experience mirrors domestic UPI usage, which reduces friction.

Bilateral bank transfers. The Singapore linkage has demonstrated that real-time, low-cost transfers between national payment systems are technically feasible. The volumes are modest but growing.

Diplomatic traction. Multiple countries have expressed interest in either linking their domestic systems to UPI or adopting UPI’s technical architecture for their own payment systems. This positions India as an exporter of financial infrastructure rather than just a consumer of Western financial technology.

What’s Not Working Yet

Volume. International UPI transactions remain a tiny fraction of domestic volumes. Adoption is limited by merchant acceptance, consumer awareness, and the availability of participating banks in partner countries.

Interoperability complexity. Each bilateral linkage requires separate technical integration, regulatory negotiation, and currency conversion arrangements. There’s no single “plug and play” framework that allows a new country to connect to UPI quickly. Each connection is a bespoke project.

Currency conversion costs. While the transaction itself may be low-cost, currency conversion margins still apply. Banks and payment processors earn their margin on the exchange rate spread. Until this is addressed through competitive FX marketplaces or regulated rate transparency, the cost savings for consumers will be less than headline figures suggest.

Regulatory mismatches. Different countries have different KYC requirements, data localisation rules, and transaction limits. Reconciling these with India’s regulatory framework for each bilateral connection is a slow process.

Implications for Indian Fintech

UPI’s international expansion creates several opportunities and pressures for the broader Indian fintech ecosystem.

Cross-border payment startups. Companies that can build services on top of UPI’s international rails — travel cards, remittance apps, trade payment platforms — have a growing addressable market. The infrastructure layer is being built by NPCI International; the application layer is open for competition.

Technology export. Indian fintech companies with deep UPI expertise are consulting with foreign governments and central banks on building real-time payment systems. This advisory and implementation business is a new revenue stream for the sector.

Competition with global rails. Visa, Mastercard, and SWIFT have dominated cross-border payments for decades. UPI’s international expansion directly challenges their business model, at least in corridors involving India. The response from incumbents — lower fees, faster settlement, better digital experiences — benefits consumers regardless of who wins.

RBI’s evolving role. The central bank is increasingly acting as a payments diplomat, negotiating bilateral agreements that have both economic and geopolitical dimensions. This elevates the importance of NPCI and the RBI’s payments division within India’s broader international economic strategy.

The Five-Year View

UPI won’t replace Visa and SWIFT globally. That’s not the realistic trajectory. What it will likely achieve is becoming the dominant payment method for India-connected corridors — the 20-30 countries with the largest Indian diaspora, tourist flows, and bilateral trade volumes.

For Indian fintech, this means the total addressable market is expanding beyond domestic borders. For Indian consumers, it means cheaper remittances and more convenient international payments. For India as a country, it means a seat at the table in shaping the future of global payments infrastructure.

The execution challenges are real, and progress will be slower than the optimists predict. But the strategic direction is set, and it’s backed by genuine technical capability and growing diplomatic momentum.
