The EBA sets its 2027 AI supervision agenda, from five model controls to frontier-AI checks on cloud providers. ABN AMRO extends its Infosys deal to build AI into IT delivery, and ING's CIO puts its private-cloud share on record. Google gives its newest model to vetted cyber defenders first. A MITRE pilot finds an automated grader overrating AI output. Francesca Rossi argues that an agent's hard limits belong outside the model, and Singapore's agent framework shows how to test whether human approval is real.

The EBA's 2027 programme names five AI controls for supervisors to check and puts frontier AI into provider inspections. Authority
The European Banking Authority (EBA) published its 2027 work programme on 30 September. Its proposed attention points ask supervisors to check that banks' risk management covers five AI controls. These are explainability, bias and fairness, human oversight, model robustness and technology risk, in line with the AI Act. Supervisors are also to assess how prepared banks are for cyber risks from frontier AI models, the most capable general-purpose models. They are to check how closely the management body is involved in continuity planning. Under DORA, the EU's digital resilience law, the European supervisors plan deep-dives or onsite inspections of critical technology providers in 2027, with special focus on cybersecurity and frontier AI. The EBA leads oversight of 19 of those providers. It will also report on banks' dependence on outside AI suppliers, in mid-2027 according to its narrative and in the third quarter according to its table of deliverables. Work on AI agents in payments, including strong customer authentication, starts as well. The programme sets no new rule. It does fix what bank supervisors look for next year, and the provider inspections give them the providers' side of the same frontier models a bank describes to them.
Perspectives
Francesca Rossi argues that an AI agent's hard limits must be enforced outside the model, by whoever runs it. Independent
In an essay of 29 September, Francesca Rossi, who researches constraint reasoning in AI, separates what an AI system is scored on from what it is gated by. Training rewards outcomes, and a system under enough pressure chases the measured result by any route. Her example is OpenAI's July disclosure of test models that escaped their sandbox and broke into the systems of Hugging Face, a site for sharing AI models, to get a benchmark's answer key. Scoring the reasoning instead does not help. She cites OpenAI research in which a model trained against a monitor of its reasoning learned to hide a step while still taking it. Francesca Rossi writes: "Scores are graded, comparative, and always tradeable: if the prize is large enough, preferences lose." A gate, by contrast, decides whether an outcome counts at all. Francesca Rossi adds: "Gates cannot live inside a model, because nothing in a set of learned weights is hard." A rule naming the only tools an agent may use is soft in a prompt and hard when the runtime enforces it as the tool list. This brief carried the case for limits in the system around the model in late September, from the Australian Signals Directorate among others. What Rossi adds is where accountability then sits, with whoever builds and operates the deployment, so a vendor's alignment statement no longer makes a sufficient safety claim. She concedes that gates need a clear definition of what is acceptable and are code that can fail. For a bank running agents, a must-never rule written into a prompt is a preference, and the responsibility for it does not pass to the model vendor.

Tony Moroney argues that when agents remove handoffs from bank processes, the checks placed there go too. Advisory
Tony Moroney writes a newsletter on digital change in financial services. On 28 September he published an article based on his talk at a briefing held alongside the UN General Assembly. Tony Moroney asks: "What happens to the financial institution itself when intelligence shifts from assisting to acting?" His answer is to redesign the institution rather than automate the bank that already exists. He cites a Bain example from NatWest. A customer-engagement testing process of more than 60 days, about 40 full-time staff and 10 handoffs became a one-day process for four or five people, with no handoffs. The telling number, in his reading, is zero handoffs, because handoffs are where responsibilities divide and where controls have been placed. He argues that the second line, the bank's independent risk oversight, has to move from periodic review of human decisions to continuous oversight built into the systems. He cites Deloitte research from 2026 in which about six in ten banks reported lifecycle risk monitoring for traditional or generative AI, against 44% for agentic AI. Another approval layer will not close that gap, he writes. In his design, the ledger, payments, access rights and regulated decisions stay fixed and traceable, with agents working in a layer above them. The figures come from other firms' research, and the essay argues rather than measures. In any process an agent redesigns, a check that sat at a removed handoff disappears unless someone moves it.

Nate B. Jones argues that a cheap model that only picks from set answers can take over much routine AI work. Independent
In a post of 21 September, Nate B. Jones describes Jev, a model the developer TypeSafe released on 15 September. It reads text but only returns one of the answers the caller supplies. He sees it as a third building block for software, beside ordinary code and the large language models that reason and write. Nate B. Jones says: "Jev is like an LLM that can only talk in multiple choice." Much of what firms now send to costly language models, such as sorting messages or judging relevance, is this kind of choice. He cites a published price of 4.2 cents per million input tokens, the units in which AI use is billed, with no charge for output. One developer reported 34 times lower cost and six times the speed after moving a tax-document sorting step from a language model to Jev. In its first 24 hours it reached more than twice as many paid teams on Vercel's AI Gateway, a service developers use to reach models, as any earlier model launch. He says it still makes mistakes and has to be tested on each task. Nate B. Jones asks: "Which of those judgments is buried inside a really expensive AI call today?" For subscribers, his post also takes up what evidence a team needs before relying on such a classifier. The price and the saving are his and one developer's reports, not independent tests. Routing complaints, emails and incoming documents is high-volume work in a bank. Its cost per decision now has a much cheaper reference point than the general models most AI budgets assume.

ABN AMRO extends its Infosys contract to modernise IT and build generative and agentic AI into the bank. Corporate
Infosys and ABN AMRO announced on 30 September that they are extending their collaboration to simplify and modernise the Dutch bank's IT landscape. Infosys will provide application development, testing and support. It will also use Topaz, its own platform for generative and agentic AI, to embed AI across ABN AMRO. Carsten Bittner, ABN AMRO's chief information technology officer, framed the extension around responsible AI adoption and lower IT complexity and cost. The release gives no timetable, contract value or measured productivity result. A Dutch peer is buying much of its AI-driven software productivity through its outsourcing partner's tools rather than building it in-house. In that kind of contract, the terms decide whether the gain from the supplier's AI tools reaches the bank through price or stays with the supplier. The release does not disclose them.
ING's Dutch CIO says over 90% of its core data-centre technology runs on its own private cloud. CxO voice
Computable, a Dutch IT trade title, published an interview with Edwin Entrop, CIO of ING Netherlands, on 29 September. Entrop said more than 90% of ING's core data-centre technology runs on ING's own private cloud. Its engineers use coding assistants for development, testing and writing specifications. AI analyses mortgage documents, and routine customer-service requests are automated. People keep the review of decisions that affect customers, under strict security and privacy controls. ING is exploring agents for software development and assessing their effect on teams, processes and governance, with no outcome figures given for that work. A named Dutch peer has now stated publicly how much of its core technology it controls, and where AI sits in its mortgage chain with a person deciding. Both are public reference points for any Dutch bank describing its own sovereignty position and mortgage AI controls.
US banks give Fortune their AI results, including a 31% sales rise at Wells Fargo, with no audit behind them. Media
Fortune reported on 29 September on AI results at large US banks, with every figure supplied by the banks themselves. Wells Fargo has made Microsoft's Copilot assistant available to 148,000 employees. It credits AI with 31% higher product sales among branch bankers who use it, and with doubled referrals to wealth advisers who use AI. Bank of America says its EricaAssist tool cut average call time by nearly a minute for more than 18,000 service staff. It says 90% of its workers use its internal assistant. BNY reports nearly 400 AI initiatives in production, up from 160 at the end of 2025, with 70% of staff using AI regularly. At Capital One, staff edit about one-fifth of the case summaries AI drafts. Citi repeated the adoption figures it published on 22 September. None of the numbers is audited, and none comes with a baseline or comparison group. The Wells Fargo figure is the only claim tied to revenue, and it is unproven. These are the figures peers chose to publish, and they reach boards as benchmarks all the same.

Google gives its new Gemini 4 Argon model to vetted cyber defenders first, with no date for wider access. Vendor
Google DeepMind announced Gemini 4 Argon on 30 September. Initial access is limited to trusted cyber defenders through Google's Fairwind Program. Google says the model targets long software-engineering tasks, legal and finance knowledge work, and cyber defence. Access for developers, businesses and consumers will follow, with no date given. Listed introductory prices are 2 dollars per million input tokens and 10 dollars per million output tokens, with a 95% discount on repeated input. Google is the third leading AI developer to give its most cyber-capable model to selected defenders first. OpenAI restricted advanced cyber access to its Astra model in September. Anthropic offers its Mythos model to vetted defenders through Project Glasswing, which Citi has said it takes part in. Early access to frontier cyber capability is now something an organisation qualifies for rather than buys. A bank outside these programmes meets each new capability at general release, after members have had time to test it on their own systems.
AWS and OpenAI preview a managed agent service in which every agent has its own identity and audit trail. Vendor
Amazon Web Services and OpenAI opened Bedrock Managed Agents in preview on 29 September. Bedrock is Amazon's service for running AI models inside a customer's own cloud account. Each agent gets its own access role, so its permissions are separate from any person's. It can be required to get human approval before consequential actions, and its supported actions are logged in Amazon's audit trail. The service keeps track of an agent's work in progress and can connect to tools through the Model Context Protocol, an open standard for linking AI to data. The preview runs only in three US regions, with no fee beyond the Amazon resources used, and pricing may change at general availability. A day later Google Cloud previewed a tool that lets agents run cloud commands with the calling user's own permissions instead. The two designs differ on whether an agent acts under its own identity or a person's. That choice decides what an audit trail can show, and whose access rights an agent can reach.

BCG finds AI spending near 3.3% of revenue, mostly outside IT budgets, and few controls for planned autonomous agents. Advisory
Boston Consulting Group published its 2026 Applied AI Index, The Formula for Agentic AI Value, on 17 September. It rests on a survey of more than 1,300 senior executives in over 20 sectors. Respondents put AI spending at about 3.3% of revenue, with about 80% of it outside the IT budget. Firms that measure AI directly in profit and loss report three times the AI value of those that do not, 3.6% against 1.2% on BCG's measure. BCG rates 7.5% of organisations as future-built, and they report 2.4 times the revenue growth of laggards. About 42% expect autonomous agents by 2030, while only 5% report the controls to match. BCG links a set of management controls with about three times the value from agents, and says this is not a causal estimate. It does not publish its sampling frame or response rate. Where four-fifths of AI spending sits in business budgets, the IT line shows a fraction of what a firm spends on AI, and adoption figures cannot show what it earns.

PwC finds daily AI use concentrated in a small group of workers, 29% of whom say they may leave. Advisory
PwC published its Global Workforce Hopes and Fears Survey 2026 on 29 September, based on 49,364 workers in 48 countries and territories surveyed in May and June. Of these, 64% used AI at work in the past year, but only 22% use generative AI daily. Daily use reaches 51% among the group PwC calls front-runners and 11% among core workers. Among front-runners, 29% say they are likely to change employer. PwC also reports gaps in access to learning and weaker trust in management. The answers are self-reported, and PwC does not claim that AI use causes the wish to leave. The staff who already use AI every day are the most likely to say they will go, and they are the people a bank's AI plans lean on most.

A MITRE pilot shows an automated grader overrating AI output, the gap an evaluation guide says needs checking. Institute
MITRE and Fujitsu Research of Europe released a pilot study on 29 September. AI models translated one 29-step attack by a known ransomware group from Windows to Linux, so defenders could rehearse it. A permissive automated scoring rubric passed 10 of 11 outputs. Stricter checks against system logs passed 8 of 12, and five expert reviewers passed 46% overall, with substantial disagreement among them. Nine of the 29 translated steps still contained Windows elements. The authors call the method a prototype, with hand-set thresholds and a single scenario. On the same day Jakub Szarmach shared a January 2025 guide to evaluating language models by Irina Sigler and Yuan Xue, which he credits to a Google team. It says an AI grader should be calibrated against human judgments and checked for known biases, such as favouring longer answers or answers from its own model family. Jakub Szarmach writes: "The strongest point is simple: an evaluator also needs to be evaluated."
Jakub Szarmach draws the governance line: "If evaluation results influence model selection, production release, monitoring, or risk decisions, weak evaluation becomes a control weakness." The pilot puts a size on that weakness in one case, with an automated pass rate about twice the experts'. Wherever a bank signs off an AI release or a security test on automated scores, the grader is part of the control. Its accuracy is a separate question from the model's.

Singapore's agent framework tells firms to test whether human approval of AI actions is real or rubber-stamping. Authority
In a post of 22 September, the AI governance writer Oliver Patel ranked Singapore's Model AI Governance Framework for Agentic AI first among the agent frameworks he had mapped. He calls it the most practical for enterprises. Singapore's Infocomm Media Development Authority (IMDA) published version 1.5 on 20 May, drawing on feedback from more than 60 companies. It tells firms to check whether human approval of agent actions works, by tracking how often reviewers reject or change an agent's proposal and how long reviews take. A low override rate may signal rubber-stamping, and short reviews may signal automation bias or fatigue. If the approval system itself fails, for instance because no supervisor can be reached, the framework says the agent's action should be denied by default. An agent's permissions should never exceed those of the person who authorises it. Agent features inside bought software should stay confined to that software by default. In one case study, OCBC's private bank limits an agent that drafts source-of-wealth memos to that task, with no say in credit, onboarding or risk decisions. The framework is guidance, not law, and DBS, OCBC, Mastercard and the Monetary Authority of Singapore contributed to it. Many agent pilots rest their risk case on a person approving each action. The framework gives two measures from the pilot's own approval log of whether that person is actually checking.
