Bank of Ireland Names First Chief AI Officer, Hiring Citigroup's Prag Sharma

What happened

Bank of Ireland has appointed Prag Sharma, formerly of Citigroup, as its first-ever chief AI officer. The move marks a significant structural commitment by one of Ireland's largest retail and commercial banks to embed artificial intelligence at the executive level, rather than treating it as a technology-department concern.

Sharma's arrival from a global institution of Citigroup's scale signals that Bank of Ireland is looking to accelerate AI adoption across its operations, bringing in senior expertise with international banking credentials to lead that effort from the top.

Why it matters

Creating a dedicated chief AI officer role — particularly a first-ever appointment — is a deliberate organisational design choice, not merely a hiring decision. It tells customers, staff and competitors where the bank believes value will be created and destroyed over the next decade. For customer experience practitioners, this is the moment when AI moves from pilot project to boardroom mandate: decisions about how customers are served, how complaints are handled, how products are personalised and how friction is removed will increasingly flow through an executive with a direct seat at the leadership table.

From a behavioural economics perspective, the appointment also carries a strong signalling function. Banks compete on trust as much as on rates or features. Elevating an AI leader publicly communicates confidence in the technology while simultaneously placing accountability — and therefore a human face — on algorithmic decisions that affect customers' financial lives. That accountability architecture matters enormously when customers are asked to trust automated underwriting, AI-driven advice or predictive fraud detection.

The Renascence take

Most commentary on appointments like this focuses on the individual's credentials or the bank's ambition. What tends to go unexamined is the organisational question underneath: who does the chief AI officer actually serve — the P&L, the technology stack, or the customer?

The risk with a chief AI officer role is that it becomes an internal efficiency mandate dressed up as a customer-experience transformation. The behavioural principle at stake is trust calibration: customers will accept AI in their banking journey only when they believe the system is working in their interest, not the bank's. A customer-obsessed operator should therefore insist that the chief AI officer's success metrics include customer-perceived fairness and ease — not just cost reduction or model accuracy. If Sharma's mandate is framed around operational optimisation alone, Bank of Ireland will have hired brilliantly for the wrong job.
