As the industry marks World Fintech Day, it is worth remembering what fintech actually runs on: the connections between machines, and the credentials that authorise them. Every open banking connection, payment integration and embedded finance partnership depends on an Application Programming Interface (API) key, a service account or a token. These non-human identities now far outnumber the people in any financial organisation, and most carry standing access that no one reviews until something goes wrong.

Cybercriminals have noticed: Verizon’s 2026 Data Breach Investigations Report found credential abuse featured in 39% of breaches, and third-party breaches surged 60% to account for nearly half of all cases – a direct warning for a sector built on integrations. Akamai’s research found 96% of financial services firms experienced at least one API-related security incident in 2025. Fintech’s greatest strength, its interconnectedness, is also its most exposed surface.

Regulators across APAC are responding in real time. Japan’s Financial Services Agency introduced mandatory cybersecurity self-assessment requirements for financial platforms effective April 2026, with penetration testing obligations to follow. The Monetary Authority of Singapore’s TRM Notice revision closes its consultation window this week, with compliance becoming mandatory within 12 months of the final notice – covering continuous monitoring, incident management, IT asset management, capacity planning and data backup with tighter third-party oversight as part of a parallel MAS initiative. Australia’s APRA prudential standards reinforce the same direction. The message from regulators across the region is consistent: continuous verification and documented control of privileged access are no longer optional.

For security and compliance teams in financial services, the practical response is clear. Standing privileges should give way to just-in-time access, and service accounts and API keys should carry least-privilege access by default. Phishing-resistant multi-factor authentication should be enforced at every login point, and the most sensitive data should remain encrypted at the infrastructure level. The controls apply equally to human users and the machine identities that now dominate fintech environments.

Fintech has earned its place in the financial system by making trust programmable. The next stage of that growth depends on proving that trust can also be governed. On World Fintech Day, the standard worth holding is this: verify every connection, account for every credential and log every session.
