LONDON (Reuters) - Banks must anticipate risks from using artificial intelligence (AI) and machine learning (ML) in their operations as part of their day-to-day governance, a top global banking regulator said on Wednesday.

There are unanswered questions on whether the use of AI or ML in banking is a net positive or negative to global financial stability, said Bank of Spain Governor Pablo Hernandez de Cos, who chairs the international Basel Committee on Banking Supervision.
