With UPI now accepted in nine countries, Indian travelers are choosing between digital convenience and traditional forex cards. Understanding the cost differences—from currency markup fees to interbank exchange rates—is key to optimizing travel budgets.
What Happened
The Unified Payments Interface (UPI) has rapidly extended its global reach, now operational in nine countries including Singapore, the UAE, Nepal, Bhutan, France, Mauritius, Qatar, Sri Lanka, and Cambodia. Developed by the National Payments Corporation of India (NPCI) through its international arm, NIPL, this expansion allows Indian travelers to scan and pay at select international merchant outlets using their familiar mobile banking apps. This development is challenging the long-standing dominance of traditional foreign exchange (forex) cards, prompting travelers to reconsider how they manage money while abroad.
Why This Matters For Investors
For the broader financial ecosystem, this shift represents a move toward digital-first, low-friction cross-border payments. Traditionally, banks and fintech companies have earned significant revenue from forex cards and international credit card transactions through currency conversion markups and issuance fees. The adoption of UPI for international payments introduces competition to these legacy revenue streams. While UPI is not yet a complete replacement for forex cards, it signals a strategic evolution where digital payment networks—backed by domestic infrastructure like India's UPI—are increasingly challenging international card networks (like Visa and Mastercard) in specific corridors. This development is a key monitorable for investors tracking the digital transition in the banking and fintech sectors, as it impacts how transaction fees are captured and how payment infrastructure is utilized.
Comparing Costs and Practicality
Choosing between UPI and forex cards involves understanding different cost structures. Forex cards allow travelers to lock in exchange rates before their trip, providing budget certainty. However, these cards typically carry a currency markup fee—often ranging from 1% to 3.5% plus GST—along with potential issuance and reloading charges.
In contrast, UPI transactions generally use the prevailing interbank exchange rate at the time of payment. While the app itself might not charge a fee, the user's bank may still levy a foreign exchange markup or conversion spread on the transaction. Investors and travelers should note that while UPI is cost-effective for small, daily expenses, it does not currently offer the same universal acceptance as physical or virtual forex cards, which are supported by global payment gateways.
Regulatory and Practical Realities
While the convenience is evident, UPI’s international usage is subject to specific constraints. Regulators have implemented security measures, such as the requirement for live scanning of QR codes, to prevent misuse and ensure compliance with international financial norms. Furthermore, merchant acceptance is not yet uniform. In many countries, UPI is popular at large retail chains, airports, and tourist hubs, but small, local vendors may still prioritize cash or traditional card payments. Additionally, users may experience occasional network latency or app-specific issues depending on the partnership between the Indian bank and the local acquiring entity.
How Investors May Read This
For investors, the key monitorable is the pace of adoption. As UPI infrastructure matures in these nine countries and potentially expands to others, the volume of cross-border transactions processed through domestic rails will rise. The real-world competition will be between the convenience of 'scan-and-pay' versus the reliability and high acceptance of traditional forex instruments.
Successful cross-border expansion for UPI could lead to broader integration, where digital payment platforms become the primary interface for international spending. However, until universal merchant acceptance is achieved, a hybrid approach—carrying a forex card for large expenditures and emergencies while using UPI for day-to-day purchases—remains the industry-standard recommendation. Investors should watch for further partnerships between NPCI and global banks, as these will determine the speed at which this payment corridor grows and how it eventually impacts the profitability of traditional forex business models.
