The Bank of England’s governor, Andrew Bailey, has joined the throng of figures warning about the global risks posed by the most advanced artificial intelligence technology.
In a two-page letter sent to international finance ministers and central bank governors as part of his role as chair of the international Financial Stability Board (FSB), Bailey said “frontier” AI models were “showing increasingly sophisticated autonomy and problem-solving abilities, as well as threat capabilities”.
He said the models risked destabilising the “highly interconnected” global financial system via cyber-disruption that “can spread across jurisdictions”.
Bailey wrote to G20 finance ministers and central bank governors before their meeting in North Carolina, US, this week: “Recent developments have also highlighted to me that many jurisdictions do not have the protocols in place to manage the development, release, and deployment of advanced frontier AI models, heightening risks for the financial sector and beyond”.
His letter adds to alarm bells about AI that have been sounded by prominent technologists over the past few weeks – and mirrors his previous calls for international cooperation to tackle growing AI threats, when he told City bosses: “No country can seal itself off from the cross-border nature of systems that are prevalent today.”
Last month, a letter signed by 1,367 researchers and engineers at frontier AI labs – mainly OpenAI, Anthropic and Google DeepMind – also shone a light on the concerns of the engineers working on the technology every day.
It stated: “There is a real risk that capability development rapidly accelerates beyond our ability to understand or control the resulting systems,” before going on to ask for the US government’s support for “an international effort to develop the technical and governance tools needed to deliberately pace the frontier of automated AI development”.
Earlier this month, it also emerged that OpenAI staff observed signs of rogue behaviour among its cutting-edge AI agents weeks before they escaped their training environment to launch an unprecedented hacking crusade that spread global alarm.
Extending this theme into the world of financial policy, Bailey continued: “For the financial system, the most immediate concern is the potential impact of frontier AI on cyber-risk. Frontier AI may have the ability materially to alter the speed, scale and economics of cyber-risk, which could undermine market confidence system-wide, especially due to highly concentrated third-party service providers.”
Bailey called on those tasked with safeguarding the world’s financial systems to prioritise “appropriate steps to support safe and responsible model release and deployment on a global basis”.
The letter also noted Bailey’s concerns about the increased use of leverage in bond and equity markets, which he said was combining with high valuations in concentrated financial markets – particularly fuelled by investor optimism about the prospects of AI – in a way that could amplify a future market correction.
“I remain concerned therefore that a large shock or combination of shocks could concurrently trigger multiple vulnerabilities,” Bailey wrote.
Bailey has been governor of the Bank of England since March 2020, and previously headed both the Financial Conduct Authority and the Prudential Regulation Authority, the UK’s two main financial regulators. He was appointed chair of the FSB last year.
The FSB, based in Basel, Switzerland, coordinates the work at international level of national financial authorities and international standard-setting bodies in an effort to develop effective regulation and policies in the interest of financial stability.
Four leading AI models discuss this article
"The centralization of frontier AI infrastructure creates a systemic fragility that current market valuations fail to account for as a potential catalyst for a liquidity-driven shock."
Andrew Bailey’s warning highlights a critical 'concentration risk' in the financial sector. By relying on a handful of cloud providers—AWS, Azure, and Google Cloud—for frontier AI, the global financial system has created a single point of failure. If an AI-driven cyberattack exploits these shared infrastructures, the contagion would be instantaneous. While the market currently prices in AI as a productivity tailwind, it ignores the systemic fragility of these dependencies. We are essentially building a global financial grid on top of an unproven, autonomous software layer. This isn't just about cyber-risk; it's about the potential for a liquidity trap if automated trading algorithms react to a common AI-triggered shock.
The strongest counter-argument is that AI-driven defensive security tools are evolving faster than offensive capabilities, potentially making the financial system more resilient to cyber-threats than it was in the pre-AI era.
"The real risk isn't rogue AI attacking exchanges—it's that AI-driven asset concentration + existing leverage creates a fragile system where any shock (AI disappointment, geopolitical event, rate surprise) triggers synchronized margin calls across illiquid positions."
Bailey's letter conflates two distinct risks that deserve separate scrutiny. The cyber-disruption threat to financial infrastructure is real but largely speculative—no demonstrated AI-enabled breach has yet destabilized markets. More concrete is his second concern: elevated leverage + concentrated valuations + AI-driven euphoria creating a fragile system vulnerable to 'large shocks.' The timing matters. He's essentially warning that if AI hype deflates or a geopolitical shock hits, margin calls cascade through concentrated positions faster than regulators can respond. This isn't fearmongering; it's a structural vulnerability. But the article conflates frontier AI autonomy risks (largely theoretical) with actual financial fragility (measurable today).
Bailey chairs the FSB, an institution whose relevance and budget depend on identifying systemic threats—regulatory agencies have structural incentives to overstate risks. Moreover, if AI cyber-threats were imminent, he'd likely be more specific about incidents or timelines rather than speaking in abstractions.
"Frontier AI's immediate threat to financial stability is overstated; the material risks are traditional cyber, liquidity, and leverage dynamics rather than frontier AI breakthroughs."
Bailey's warning underscores plausible tail risks from frontier AI and heightened cyber exposure due to outsourcing and vendor concentration. Yet the article's framing risks overstating immediacy: 'frontier' AI is poorly defined, and we lack empirical evidence that autonomous AI will meaningfully alter cyber risk on a system-wide scale in the near term. The real miss is context: regulators are already strengthening cyber governance, and market infrastructure is diversified across multiple service providers. The bigger near-term shock drivers remain leverage, liquidity strains, and macro shocks, not unproven capabilities of frontier AI. Expect policy chatter to outpace actionable risk management in the coming months.
Even if the probability is low, the tail risk of a systemic AI-driven cyber blow could erase confidence and liquidity; such an event would be destabilizing regardless of its anticipated likelihood. Moreover, overzealous regulation could trigger volatility or misallocate capital away from productive activities if policy moves are reactionary rather than evidence-based.
"Bailey flags plausible AI-amplified cyber and leverage risks but the letter supplies no evidence these threats are near-term or unmanageable under existing protocols."
Bailey's FSB letter highlights frontier AI's capacity to scale cyber attacks across concentrated third-party providers, potentially triggering system-wide confidence loss, while AI-fueled leverage in equities and bonds could magnify any correction. The piece underplays that current financial cyber defenses and existing stress-testing regimes already target similar tail risks, and no verified frontier-model incidents have yet materialized in live financial infrastructure. The letter's timing before G20 talks points more to regulatory positioning than immediate danger. Markets may price in these warnings as standard FSB caution rather than new information.
These concerns rest on hypothetical capability jumps; no data shows frontier models have altered cyber economics in finance today, and historical tech warnings have often preceded productive integration without systemic events.
"Regulatory responses to AI cyber-risk will likely entrench cloud provider monopolies by creating insurmountable compliance costs for smaller fintech competitors."
Claude and Grok are missing the second-order effect of 'regulatory capture' via AI compliance. If the FSB mandates proprietary, audited AI security layers, we create a barrier to entry that cements the dominance of current cloud incumbents. This isn't just about systemic fragility; it’s about creating an oligopoly where only AWS, Azure, and Google can afford the compliance overhead. The real risk isn't just an AI-driven crash—it's the permanent stifling of fintech innovation through mandated, expensive security theater.
"Regulatory mandates on AI security don't automatically entrench incumbents—they could force interoperability that reduces concentration risk."
Gemini's regulatory capture thesis is sharp, but it conflates two separate dynamics. FSB mandates on AI security don't inherently favor incumbents—they could equally force AWS/Azure/Google to open APIs or share audit trails, lowering barriers for smaller competitors. The real oligopoly risk isn't compliance overhead; it's that three providers already control 65%+ of cloud infrastructure. Regulation might actually fragment that, not cement it. The fintech stifling concern is valid, but it's a cost-of-safety trade-off, not a hidden mechanism.
"Regulation can reduce concentration risk if it enforces interoperability and open auditability, not entrench incumbents through costly 'security theater'."
Gemini's claim that AI compliance would automatically entrench the incumbents rests on a worst-case cost view. In practice, a security framework that mandates interoperable APIs and verifiable audits could dilute cloud-concentration by lowering switching costs for fintechs and enabling best-of-breed security providers to compete. The risk remains if standards are narrow or expensive, but dismissing regulation as merely protectionism ignores the potential for higher resilience and vendor diversity through open standards.
"AI security mandates will likely deepen cloud concentration by turning compliance into an incumbents-only revenue stream."
Claude assumes FSB rules could force API openness and fragment the 65% cloud oligopoly, yet compliance regimes typically raise fixed costs that only scale players absorb first. AWS, Azure, and Google already operate the audit infrastructure; they will package mandated security layers as paid add-ons, converting regulatory burden into deeper lock-in. This directly magnifies the concentration risk Bailey flagged rather than offsetting it.
The panel agrees that the reliance on a few cloud providers for AI in finance poses significant risks, including systemic fragility and potential regulatory capture. They warn of a 'concentration risk' that could lead to a single point of failure in case of an AI-driven cyberattack. However, they differ on the immediacy and the impact of these risks, with some panelists arguing that the market is overstating the threat of frontier AI.
