As fintech continues to reshape global finance, both startups and established players are learning that innovation often outpaces regulation. With no universal set of standards, this regulatory lag becomes even more pronounced. Companies expanding internationally need to navigate complex payment regulations that govern customer identification processes, data security measures, and operational authorization requirements.
We define regulatory arbitrage as the practice of establishing financial and technological operations in jurisdictions with lower regulatory barriers. The diversity of financial regulations worldwide creates both obstacles and opportunities, as companies leverage regulatory arbitrage by selecting jurisdictions and infrastructure configurations based on regulatory advantages.
Building financial systems in fintech requires designing solutions with compliance in mind. Organizations that engage in regulatory arbitrage strategically can expand more rapidly while establishing sustainable operations.
KYC and Identity Standards
Globally expansion begins with managing substantial variations in Know Your Customer (KYC) regulations. Different jurisdictions impose different standards, requiring fintech companies to work with diverse data points. For instance, U.S. fintech companies use credit bureau data alongside public records to verify identities, whereas companies in India must integrate with the government-issued biometric ID system, Aadhaar, for onboarding. In the EU, the eIDAS regulation adds another layer of compliance by enhancing digital signature security and identity validation procedures.
Companies need to create separate onboarding processes for each region, leading to parallel systems that meet local laws but increase engineering complexity and affect the user experience.
For example, an international retailer based in Europe paying sellers in the U.S. for cross-border sales might have a relatively simpler onboarding flow requiring only bank account or wallet details and tax information. However, payments to suppliers in China typically require additional checks, including verification of seller identity, business legitimacy, AML compliance, and submission of KYC documentation.
Regulatory compliance burdens often shift to fintech providers or even the importing customers. In the China example, fintechs may need to collect extensive documentation—such as itemized invoices and payment declaration forms—for transactions to clear. In South Africa, customers buying international products (as importers of record) must provide their South African National ID to ensure they stay within their annual import quotas.
Balancing Innovation and Regulation
The implementation of regulatory sandboxes by various countries aims to simplify compliance requirements while fostering technological innovation. These testing frameworks allows fintech companies to trial their products within controlled environments subject to fewer regulatory restrictions. The UK’s Financial Conduct Authority initiated this practice, prompting regulators like Singapore’s MAS and the Central Bank of Bahrain to adopt similar models. In Singapore, the sandbox enabled fintech companies to pilot cross-border remittance services before securing full licenses—accelerating market entry while ensuring legal compliance.
The South African Reserve Bank’s (SARB) Financial Surveillance department (FinSurv) administers a regulatory sandbox that allows select fintechs to innovate with the goal of simplifying regulatory reporting. Ozow, a South African fintech, recently took part in this initiative and successfully demonstrated a scalable cross-border solution. This solution enables international retailers such as Shein and Temu to pay sellers outside of South Africa directly into their bank accounts for retail imports—a significant improvement over the previous reliance on costly international credit or debit card transactions with added foreign transaction fees.
But sandboxes aren’t infallible. Several fintech companies have expressed disappointment over their restrictive nature. For example, GoPay’s transition from sandbox participation to full licensing in Indonesia took more than 18 months, hindering its ability to expand operations despite strong market demand.
Security vs. Speed in Global Fintech
The ongoing trade-off between security and speed remains one of the greatest continuous challenges fintech companies face when expanding across borders.
Data localization laws impose complex barriers to operations in different international markets. The EU’s GDPR, alongside India’s data sovereignty laws, requires payment data to be stored within national borders. As a result, fintech companies must deploy multiple regional infrastructure systems, increasing costs and reducing operational performance.
Some fintech payment operations have opted to route transactions through countries with less stringent regulatory frameworks. Within Europe, Ireland and Lithuania have emerged as major hubs due to their open regulatory environments and streamlined licensing procedures. Companies leverage licenses from these jurisdictions to process European transactions with greater flexibility and reduced compliance delays.
However, real-time payment systems—which enables fast transfers to customers—introduce increased security risks by shortening the window for compliance reviews. The legal framework in certain regions compound these risks. For instance, in Kenya, transactions via M-Pesa become irrevocable once received unless the recipient consents to reversal.
Real-time payment systems including Brazil’s Pix and India’s UPI have transformed local transactions through rapid processing and reliable service. By contrast, most cross-border transactions still move through correspondent banking networks, which offer slower yet regulator-endorsed, highly secure transaction pathways.
Each region presents its own distinct security risks. In Europe, PSD2’s Strong Customer Authentication (SCA) requirements help financial institutions reduce fraud activities. Meanwhile, in Latin America, fintech companies face prevalent threats like account takeovers and phishing attacks—necessitating adaptive security models that respond quickly to evolving regional threats.
Turning Regulatory Complexity into Competitive Advantage
Cultural expectations add another layer of complexity. Users in some countries will tolerate delayed payment processing if it includes strong anti-fraud measures. In contrast, users in the United States and Southeast Asia expect payments to be faster than real-time—anything slower feels broken. MENA users often prefer transacting via wallet apps like STC Pay, presenting payment providers and fintechs with added regulatory and technical complexity, as wallet infrastructures are not standardized like card networks. Fintech companies need to adapt their UX and infrastructure to meet user expectations and regulatory requirements, striking a delicate balance between performance and perception.
Expanding fintech businesses across borders now requires more than product innovation—it requires sophisticated legal engineering. The regulatory frameworks governing global payments demand strategic foresight. Every expansion decision involves regulatory and technical negotiation. Companies must tailor KYC protocols and manage fragmented data infrastructures, balancing speed with security. Those that navigate regulatory arbitrage while preserving user trust will gain more than just market entry. Building adaptable systems on resilient infrastructure positions companies to succeed in a shifting global environment. The future competitive edge for fintech will hinge not just on speed, but on making compliance a core pillar of global growth.
