# Trefoil Consulting

Trefoil Consulting is a specialist risk and regulatory advisory firm based in London's financial district, serving financial institutions navigating complex regulatory frameworks and transformation initiatives. The firm provides expert guidance across market risk, capital modelling and regulatory compliance, with particular depth in Basel III and FRTB (Fundamental Review of the Trading Book) implementation.

The consultancy works with tier-one investment banks and financial firms tackling regulatory change programmes, stress testing requirements and capital model design. Their three founding partners bring over 50 years of combined experience in financial services, including leadership roles on enterprise-scale technology implementations and regulatory engagements with supervisory authorities.

What distinguishes Trefoil is their hands-on expertise in FRTB standardised approach implementation—Neal Coughlan designed the industry standard unit tests for FRTB-SA capital models on behalf of ISDA. The team combines strategic programme management with deep technical knowledge, able to own deliverables from requirements definition through to release testing. They excel at translating regulatory interpretations into practical solutions and managing large-scale transformations across both waterfall and agile delivery models.

Rather than generic consulting, Trefoil offers domain-specific support in stress testing integration, solution architecture, model validation and capital optimisation—the granular challenges financial institutions face during regulatory transformation. Their advisory extends to supervisory engagement preparation, helping firms represent current industry perspectives to regulators effectively.
