· Sebastien Rousseau

Agentic payments in 2026 have moved from concept to live transaction. The banking challenge is no longer whether AI agents can initiate payments, but how consent, liability, identity, auditability, fraud controls, and protocol interoperability should work.

Agentic Engineering for Banks: A 2026 Blueprint for the C-Suite and the Engineers Who Will Build It

· Sebastien Rousseau

Agentic AI has crossed from pilot into production across global banking. 70% of institutions are using it to some degree; only one in five has a mature governance model. Meanwhile, autonomous adversaries are operating at machine speed, the legacy COBOL estate the new systems must interoperate with was written for the batch-processing assumptions of the 1960s, and the EU AI Act's August 2026 high-risk deadline is twelve weeks away. This is the engineering and governance position a bank needs to hold.
