    Key Findings

    • 2Open banking APIs now process over $1.2 trillion in transaction volume annually across major markets.
    • 3Africa's embedded finance opportunity is uniquely large due to the 57% unbanked adult population and mobile-first infrastructure.

    • 5The winners will be platforms that embed financial services invisibly into everyday commercial transactions.

    Sector Overview

    Open banking — the practice of sharing financial data through secure APIs — has moved from regulatory aspiration to commercial reality. The UK's Implementation Entity processes over 11 million API calls daily . The EU's PSD2 framework covers 450 million consumers. Brazil's Open Finance ecosystem has enrolled 30 million users since launch .

    But the real revolution isn't in banking — it's in what happens when financial services become invisible. Embedded finance — the integration of banking, lending, insurance, and payments into non-financial platforms — is fundamentally changing how consumers and businesses interact with money .

    When Shopify offers working capital to its merchants, when Uber provides instant driver payouts, when Amazon embeds buy-now-pay-later at checkout — these aren't technology add-ons. They're the future of financial services distribution .
