- Global Frameworks: European Union PSD2/PSD3 (Payment Services Directives), Bank for International Settlements (BIS) Open Banking Standard Frameworks.
1. The Decentralization of Financial Intermediation
The global FinTech architecture represents a structural shift from traditional, centralized banking systems to decentralized, technology-driven financial service platforms. This transformation leverages APIs, cloud computing, and automated data networks to unbundle core banking products into agile, specialized digital solutions.
2. Open Banking and Regulatory Directive Architectures
- PSD2/PSD3 Frameworks: In the European Union and the UK, Payment Services Directives mandate that commercial banks securely open their customer transaction data networks to licensed third-party providers, conditional on explicit customer consent.
- Account Information Service Providers (AISPs): Aggregators that extract and consolidate multi-bank transactional data into a single financial overview interface for the user.
- Payment Initiation Service Providers (PISPs): Platforms that trigger digital payment transactions directly from a user’s bank account, bypassing traditional, high-fee card payment rails (such as Visa or Mastercard).

3. Peer-to-Peer (P2P) Lending and Crowdfunding Mechanics
Digital platforms bypass traditional bank balance sheets by directly matching surplus capital providers with deficit capital consumers.
- P2P Credit Underwriting: Employs non-traditional alternative data (e.g., e-commerce transaction histories, utility billing records) paired with machine learning algorithms to assess creditworthiness in real time. This process broadens access to credit while skipping the delays of manual bank approval loops.
