• Regulators are reportedly tightening oversight of AI in banking, driven by cyberattack risk and the possibility of rogue AI agents; the account rests on unnamed sources cited by Reuters.
• The FSB's October 2025 report describes AI monitoring by authorities as early-stage, limited by data gaps and the lack of standardised taxonomies.
• Concentration in a few critical AI providers is a flagged vulnerability, because a single outage or compromise could hit many banks at once.
• For Gulf banks and challengers, the practical exposure is third-party AI vendor dependence, not in-house models.
• Watch for formal supervisory guidance, since the current reporting describes intent and not published rules.

Banking supervisors are reportedly stepping up their oversight of artificial intelligence. PYMNTS, relaying a Reuters report of Tuesday, 13 October, says the push is driven in part by the threat of cyberattacks on banks and by rogue AI agents that could hinder financial stability. The account relies on unnamed sources, and no new rule text has been cited, so it describes direction of travel rather than binding requirements.

What is actually confirmed

Little beyond intent is confirmed. The Reuters account, as summarised by PYMNTS, cites people familiar with the matter and names two drivers: cyberattacks on banks and rogue AI agents. It does not, in the summary available, name a regulator, a rule or a deadline. Treat it as a signal of supervisory attention, to be tested against the guidance that supervisors eventually publish.

The monitoring gap behind the push

Authorities are tightening oversight with weak instruments. The Financial Stability Board's October 2025 report on monitoring AI adoption, prepared at the request of the G20, describes monitoring as early-stage and cites data gaps and a lack of standardised taxonomies. It proposes direct and proxy indicators, gathered through surveys and supervisory engagement. Supervisors cannot yet measure the exposure they are trying to control.

Concentration is the systemic angle

The most concrete systemic worry in the FSB's work is dependence on a few providers. The October 2025 report includes a case study on the AI supply chain and raises concerns about criticality, concentration and substitutability of third parties. For banks, the point is that one vendor outage or compromise can hit many institutions at once, which turns a firm-level operational risk into a correlated one.

What it means for Gulf banks and challengers

Challengers are the most exposed to vendor concentration, because lean teams buy fraud scoring, onboarding checks and customer service automation instead of building them. Expect supervisors to ask which third-party AI sits in critical flows, what the fallback is, and who can switch it off. No Gulf regulator has been named in the reporting, so this is an inference from the global direction.

The practical response is documentation before regulation arrives: an inventory of AI systems in production, the vendor behind each, the human override path, and a tested manual fallback for authorisation, fraud and onboarding decisions. Banks that can show this will face lighter questions once formal guidance lands. What to watch next is whether any supervisor publishes text that converts the reported concern into obligations.
