Writing executable financial contracts remains a challenge due to the linguistic gap between legal prose and computer code. Logical English (LE) bridges this divide, offering a human-readable yet executable framework. This article examines the emergence of “vibe coding”–an iterative, agentic workflow using Generative AI – to automate contract development. By leveraging Large Language Models to translate legal intent into formal LE structures anchored in the Common Domain Model, the industry can move toward a “vibe-to-code” reality. This approach harmonises the probabilistic power of AI with the deterministic certainty required for banking law and complex derivative documentation.
