For banks, the question is whether to consume cloud or design it — under converging pressure from agentic commerce, agentic unit economics, harvest-now-decrypt-later quantum risk, MCP security and algorithmic contagion, cryptographic agent identity, continuous-treasury demands, and the EU AI Act.contact@sebastienrousseau.com (Sebastien Rousseau)Agentic Engineering for Banks: A 2026 Blueprint for the C-Suite and the Engineers Who Will Build Ithttps://sebastienrousseau.com/yo/2026-05-18-agentic-engineering-banks-blueprint-2026/2026-05-18T06:06:06+00:002026-05-18T06:06:06+00:00Agentic 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.contact@sebastienrousseau.com (Sebastien Rousseau)Stablecoin Yield by Another Name: BlackRock's BRSRV and BSTBL Filings Decodedhttps://sebastienrousseau.com/yo/2026-05-15-blackrock-brsrv-bstbl-genius-act-tokenised-mmf/2026-05-15T06:06:06+00:002026-05-15T06:06:06+00:00Stablecoins cannot pay yield under the GENIUS Act. On 8 May 2026, BlackRock filed two SEC registrations for products that solve this constraint by being regulated as money market funds rather than stablecoins — while behaving, in the wallet, like yield-bearing dollars.

With the G7 roadmap published in January 2026, the EU, UK, and ASD timelines clarified, and the BIS Project Leap proving feasibility at the central-bank level, the question for boards is no longer whether to migrate — it is whether the migration can be completed before the cryptographic shelf-life of today's data expires.contact@sebastienrousseau.com (Sebastien Rousseau)The November 2026 pacs.008 Structured-Address Deadline: A Six-Month Viewhttps://sebastienrousseau.com/yo/2026-05-12-iso-20022-pacs008-structured-address-deadline/2026-05-12T06:06:06+00:002026-05-12T06:06:06+00:00From November 2026, SWIFT CBPR+ requires structured postal addresses in cross-border payment messages. Unstructured address lines (AdrLine alone) will no longer be accepted for key party fields in pacs.008. At minimum, TwnNm and Ctry are required, with StrtNm and BldgNb or PstBx recommended.
