Why Responsible AI Is Essential in Finance
AI has moved from pilot projects to production. It now influences credit decisions, fraud prevention, personalised banking, and regulatory reporting. In a sector built on trust, explainability and accountability are not a nice-to-have-they're the standard.
With regulation tightening, including the EU AI Act, finance leaders need a model for scaling AI without losing control. David Fearne, Vice President of AI at NTT DATA, lays out a path where governance enables innovation instead of blocking it.
Innovation vs. Governance: It's Not a Trade-Off
The smart move is to treat governance as a growth enabler. Start with clear design intent: define which decisions AI can influence, when it must defer to humans, and how risk tolerance changes by use case.
Embed governance into delivery. Decide on model selection rules, data provenance checks, evaluation criteria, and escalation thresholds before you write a line of code. Keep testing after deployment-continuous evaluation gives teams confidence and gives regulators visibility.
Biggest Risks at Scale-and How to Reduce Them
Overconfidence is a hidden risk. A model that works in a pilot can behave differently in production with more data, more users, and more edge cases. Opacity is another: if teams can't explain decisions, accountability erodes-especially in credit or customer disputes. This gets worse when AI is bolted onto fragmented legacy stacks.
Mitigation is practical. Set hard system boundaries and enforce them technically, not just in policy docs. Build evaluation frameworks, audit logs, and escalation paths. Keep humans in the loop with real oversight-people should challenge and override outputs, and the system should learn from those interventions.
Explainability and Accountability by Design
Accuracy alone won't meet regulatory or customer expectations. Explanations should fit the audience and context-clear for customers, detailed for risk teams, defensible for auditors and supervisors. Not every model needs full interpretability, but every system needs appropriate explanation.
Accountability must be traceable. Decisions involve data inputs, model behaviour, and human approval. Make ownership explicit. Treat explainability and accountability as functional requirements to reduce review cycles, build internal trust, and increase resilience.
Using AI to Strengthen Customer Trust
Trust grows when customers feel AI works with them, not on them. Be upfront about where AI is used, why, and how to appeal outcomes. Simple, plain-language explanations demystify decisions.
Use AI to reduce friction-faster resolutions, proactive alerts, and context-aware support. Avoid over-automation in sensitive or high-impact situations. Keep human access available at the right moments. Frame AI as an assistant for both customers and staff.
What Finance Can Learn from Healthcare and Aviation
Two lessons stand out. First, continuous evaluation: systems are monitored across their lifecycle, not approved once and forgotten. Second, role clarity: responsibility is explicit, even with automation in the loop.
Consistency matters too. Apply governance predictably, not selectively. That steadiness builds confidence with regulators, practitioners, and the public-and it enables safe scale-up.
How NTT DATA Makes Responsible AI Work in Legacy Environments
Most banks aren't rebuilding from scratch. NTT DATA integrates responsible AI into existing architectures using intermediary layers-evaluation services, audit pipelines, and decision orchestration-that sit alongside core systems. You gain transparency and control without rewriting the bank.
They align AI delivery with risk and compliance processes, mapping model behaviour to regulatory expectations in testable, repeatable ways. Skills transfer is a priority so teams can govern and improve systems long after the initial deployment.
What's Next: Adaptive, Continuous Governance
Static rulebooks won't keep pace with new models and use cases. Expect continuous oversight that blends real-time monitoring and automated evaluation with clear human responsibility. Governance will be built into systems, not layered on as an afterthought.
Controls will vary by impact. High-stakes use cases will carry tighter constraints; lower-risk applications will move faster under lighter checks. Banks that can show how their AI behaves, learns, and gets corrected will earn more trust-and turn governance into an advantage.
A Practical Checklist for Finance Leaders
- Define decision rights: where AI leads, where humans approve, and why.
- Segment use cases by risk; match explainability and control to impact.
- Enforce system boundaries in code (not just in policy).
- Instrument models with monitoring, audit logging, and alerting from day one.
- Set escalation paths and thresholds; rehearse failure scenarios.
- Provide audience-specific explanations (customer, risk, regulator).
- Create human-in-the-loop workflows that allow override and learning.
- Run continuous evaluation to detect drift and fairness issues early.
- Align with regulatory frameworks like the EU AI Act and document how controls meet expectations.
