India’s Unified Payments Interface (UPI) through UPI International is expanding from a domestic phenomenon into a cross‑border contender. The question now is whether it can pry tourist spend and remittance flows away from the global card duopoly, and on what economics.
Why now
At home, UPI has become the operating system of everyday money. In August 2025, UPI processed ~20.01 billion transactions worth ₹24.85 lakh crore (just under USD 300 billion), which is a new monthly high and underscores the rail’s scale, reliability, and user habit formation.
Abroad, live merchant acceptance for UPI (NPCI’s “UPI Global Acceptance”) currently includes Bhutan, France, Mauritius, Nepal, Singapore, Sri Lanka, and the UAE, with Qatar added in late September 2025 via a tie‑up between NPCI International (NIPL) and Qatar National Bank, initially at Qatar Duty Free and expanding across QNB‑acquired merchants.
Meanwhile, India and Singapore have deepened the UPI–PayNow corridor through UPI International; in July 2025 the linkage expanded to 19 Indian banks, widening access for real‑time, low‑value cross‑border transfers.
A larger play looms: BIS’s Project Nexus, under which India joins Malaysia, Thailand, Singapore, and the Philippines to link domestic instant payment systems by 2026, potentially routing cross‑border payments “in 60 seconds”. If Nexus scales, UPI could interoperate with multiple fast-payment schemes through a single connection, rather than one-off bilateral deals.
Where UPI works today (and how)
Tourism corridors first. The strategy is pragmatic: turn on UPI International where Indian travelers already are. The UAE remains the number one destination for Indians, and UPI acceptance there continues to expand through local acquirers (NEOPAY/Mashreq, Network International, Magnati), providing merchants with a QR-based path to Indian spend without cards.
Europe is opening. France became the first EU market to accept UPI International, starting with Eiffel Tower tickets and later Galeries Lafayette’s Paris flagship, via NIPL’s partner Lyra, a template for other tourist‑heavy merchants.
Qatar just went live. The QNB–NIPL rollout enables UPI at Qatar Duty Free and other QNB-acquired merchants using QR codes at the point of sale which is well-timed for peak travel windows.
For users, UPI Global Acceptance is scan‑and‑pay. Apps display the final amount in both foreign and INR, along with applicable FX and fees before confirmation which is important because the FX spread (not a customer UPI fee) is the primary cost driver.
The UX advantage vs. cards
- Familiar flow: Indian users scan a QR and approve in their existing UPI app, which means no new wallet, no plastic, no PIN translation.
- Speed: End-to-end authorization is nearly instantaneous, mirroring domestic UPI. NPCI has also reduced API response times, resulting in faster merchant checkouts.
- Remittances, not just retail: UPI–PayNow enables small cross-border P2P transactions in seconds with daily limits (₹60,000) and narrow purposes of use which is perfect for gifts and maintenance.
Where cards still win big is ubiquity. Visa and Mastercard boast ~150 million merchant locations in 200+ markets, coverage UPI cannot match in the near term.
Can UPI beat card economics abroad?
For consumers: Indian credit cards often add ~2%–3.5% foreign currency mark‑ups (plus tax), though “zero‑markup” cards exist. Paying via UPI avoids issuer FX mark‑ups, but you still pay an FX spread embedded by the payment partner; the app displays this before you hit “pay.”
For merchants: Traditional card merchant discount rates (MDR) often land in the ~1–3% range (varies widely by region, scheme and risk), with scheme cross‑border assessments on top. QR‑based account‑to‑account acceptance can be priced more sharply in tourist corridors because it bypasses parts of the card stack and monetizes FX instead. (In India, regulators have kept UPI low‑cost domestically; that policy stance does not govern foreign acquirer pricing.)
For remittances: The global average cost of sending $500 was ~4.26% in Q1 2025, and it’s higher for smaller tickets; digital rails have been grinding that lower. If RTP linkages, such as UPI–PayNow or BIS Nexus, reliably deliver sub-3 % end-to-end, they start to crowd out legacy methods in popular corridors.
Card networks are not stationary targets. Their acceptance, risk controls, and loyalty economics are entrenched—and they can (and do) onboard A2A/Pay‑by‑Bank options via acquirers and open banking. UPI International’s advantage will be situational: Indian traveler flows, transparent FX, and instant confirmation at merchants who value conversion over card rewards.
Winners and losers (so far)
Likely winners
- Middle‑East & Southeast Asia acquirers that light up UPI QR at airports, malls, and attractions (NEOPAY, Network International, QNB): they capture Indian tourist spend and share in FX.
- European acquirers targeting tourism (e.g., Worldline with early UPI support): clear commercial upside where Indian footfall is material.
- NIPL and partner banks riding the UPI–PayNow corridor expansion to institutionalize small‑value remittances.
Potentially squeezed
- Cards on low‑ticket tourist spend where UPI QR is visible and FX is fair. Loyalty can still prompt spending back to cards for larger transactions or when tap-to-pay is faster.
What could go wrong
- Patchy acceptance. NPCI’s own live list shows just seven countries (plus Qatar now) where merchant acceptance exists, and it’s “select outlets” in most markets. Coverage, not tech, is the hurdle.
- Disputes & chargebacks. UPI has a formal dispute framework and revised TAT (45 days), but cards’ decades‑old chargeback rails are familiar to global merchants. Education and tooling will matter.
- Policy and pricing drift. India has debated introducing MDR on large domestic UPI transactions; while unrelated to cross‑border pricing, any confusion on “UPI is free” can hurt adoption abroad.
What success looks like (2026 horizon)
- Nexus goes live with India and four ASEAN peers: UPI payments flow to linked RTPs in under a minute with addressability (mobile/email) intact.
- Tourist hotspots in the UAE, Qatar, Singapore and France reach “table‑stakes” QR acceptance at airports and top attractions; large retailers display UPI/BHIM alongside Visa/Mastercard.
- Remittances in the India–Singapore corridor routinely settle via UPI–PayNow from dozens of banks, with corridor costs testing <3% at scale.
The investor takeaway
UPI will not displace cards globally in the next 12–24 months; acceptance is too narrow. But it will carve out meaningful share in a few high‑traffic corridors where Indian travelers concentrate and FX transparency resonates with price‑sensitive users. The real unlock is multilateral: if Project Nexus delivers plug‑and‑play connectivity, UPI evolves from an India‑centric overlay to a node in a global instant‑payments web—pressuring card economics on small cross‑border tickets and chipping away at remittance costs.
