In July 2025, Brazil’s Pix, an instant payment system, became the target of a U.S. trade investigation led by the Office of the U.S. Trade Representative (USTR), which questions alleged unfair practices. Meanwhile, India’s Unified Payments Interface (UPI), a similar government-backed system, remains outside the U.S. government’s scrutiny, despite both transforming digital payments. The probe comes amid Donald Trump’s tariff escalation, which raised duties on Brazilian and Indian products to 50%, though for different reasons: Brazil for Pix and India for purchasing Russian oil. Comparing the two systems reveals structural and strategic differences that explain why Pix faces external pressure. Experts note that Brazil’s centrally controlled model benefits local companies, while UPI favors U.S. giants like Google and Walmart. The investigation reflects trade tensions and competition for strategic markets.
Launched in 2020, Pix revolutionized payments in Brazil, reaching 74% of the population in three years, a global adoption record. Free, instant, and available 24/7, the system enables transfers and purchases without bank details, competing with traditional credit cards. India’s UPI, created in 2016, processes 18 billion transactions monthly and is used by 500 million Indians, accounting for 83% of digital transactions. Both systems stem from public initiatives, but their structures and global impacts differ significantly.
The U.S. investigation, launched on July 15, claims Pix harms American companies like Visa and Mastercard by promoting a state-backed system. However, experts question this narrative, noting UPI is also state-driven but operates with significant U.S. tech involvement, possibly explaining its exemption from scrutiny. The case highlights the complexity of trade relations and Brazil’s strategic importance as a market for tech companies.
- Key differences between Pix and UPI:
- Pix is directly operated by Brazil’s Central Bank; UPI is managed by a private consortium under regulatory oversight.
- Pix adoption was mandatory for large financial institutions; UPI participation is voluntary.
- UPI supports offline payments and voice commands, features absent in Pix.
- UPI has international reach, operating in countries like France and Nepal; Pix operates internationally only through private solutions.
Origin and impact of UPI in Indiatypography
UPIMazI emerged as part of India’s India Stack, a government initiative to digitize services, including a digital ID and the demonetization of cash. Developed by the National Payments Corporation of India (NPCI), a consortium of banks under the central bank’s supervision, UPI was launched to reduce physical currency use and promote financial inclusion. It now dominates India/wellIndia’s market, handling 18 billion monthly transactions and serving 500 million users. Its infrastructure integrates with digital wallets like Google Pay and PhonePe, which process over 80% of transactions.
Pix’s structure and rapid adoption
In Brazil, Pix was designed and implemented by the Central Bank, which mandated adoption for institutions with over 500,000 accounts. This decision led to a rapid adoption rate, reaching 74% of the population in three years, compared to UPI’s 25% in India over the same period. The centralized model favored local digital banks and Fintechs, such as Nubank and PagBrasil, which developed international payment solutions like Pix in Argentina and Paraguay.
The system has driven local innovation. Colombia’s upcoming Bre-B system, inspired by Pix, was developed with Brazilian company Dock. Economist Paul Krugman praised Pix for its low-cost, near-instant transactions, suggesting Brazil may have pioneered the future of money. However, the state-controlled model has limited the participation of big techs like WhatsApp, unlike UPI’s open integration.

Relationship with big techs and trade tensions
A key difference lies in the relationship with tech giants. In India, UPI transactions are processed through digital wallets, with Google Pay and Walmart’s PhonePe dominating over 80% of the market. This benefits U.S. multinationals, potentially shielding UPI from U.S. criticism. In Brazil, Pix operates within bank and fintech apps, limiting big tech involvement. WhatsApp’s payment function, launched in 2020, was suspended by Brazil’s Central Bank over competition concerns, only resuming in 2023.
Researcher Polina Kempinsky, in a Harvard study, describes big techs as “losers” in Pix’s ecosystem, as Brazil’s policy strengthens local players. The USTR’s investigation reflects tensions over Brazil’s strategic market, a major hub for WhatsApp and Google.
International expansion and global competition
UPI leads in international expansion, operating in countries like Bhutan and France, and is promoted as an alternative to Swift, the global financial transaction system. RuPay, a UPI-integrated credit card, competes with Visa and Mastercard. Pix, while not yet officially internationalized, is used abroad through private solutions like PagBrasil’s real-time currency conversion tools.
Brazil’s focus on domestic markets may contribute to U.S. pressure, as it limits foreign tech giants’ access. Thiago Aragão from Arko Advice emphasizes Brazil’s strategic importance as a top market for WhatsApp and Google.
- Planned Pix innovations:
- Automatic Pix for recurring payments.
- Enhanced e-commerce and small business integration.
- New digital financial service integrations.
- Potential official internationalization.
Implications of the U.S. investigation
The USTR’s investigation into Pix, announced in July, coincides with Trump’s protectionist policies. While the document indirectly references Pix as a government-developed system harming U.S. firms, UPI faces no such scrutiny, likely due to its integration with American companies. Brazil’s defense, led by Minister Fernando Haddad and President Lula, highlights Pix’s role in financial inclusion and innovation. Data shows a 31.7% annual growth in credit card issuance from 2020 to 2022, a trend mirrored in India with UPI.
Regulatory differences and the future of payments
Brazil’s Central Bank acts as both operator and regulator of Pix, ensuring tight control. India’s central bank regulates but leaves UPI operations to private entities, facilitating big tech participation. Brazil plans to expand Pix functionalities, while India considers capping digital wallet market shares at 30% to address privacy and competition concerns.
The U.S. pressure on Pix may spark discussions on digital sovereignty and big tech regulation. While UPI solidifies its global presence, Pix faces the challenge of maintaining relevance without yielding to foreign giants.
