These tools can help incorporate information faster, but they do not guarantee better returns or more accurate risk estimates. Their outputs are analytical inputs: how they are validated, monitored, and used matters as much as the model itself.
What AI does in market risk and investment work
“AI” is not one system making decisions for a bank. It can refer to different analytical techniques used for different tasks. The Bank of England reports that algorithmic traders already widely use established techniques such as decision trees to calibrate trading algorithms, while some investment managers are turning to AI to generate insights. The extent and speed of wider deployment remain uncertain. Bank of England, Financial Stability in Focus: Artificial intelligence in the financial system, April 2025

In practice, an AI system may help process market information, identify patterns, or produce a signal. That output might inform a risk estimate, help tune a trading algorithm, or contribute to an investment judgment. The institution’s controls determine whether and how anyone acts on it. The available evidence does not establish that a particular bank uses one end-to-end AI system or delegates final investment decisions to a model.
Risk analysis and trading support are different jobs
A model used to support risk management helps inform an institution’s understanding of its exposures; a model used to calibrate a trading algorithm helps shape how that algorithm operates. An investment insight may inform a judgment without being a trade instruction. Comparing these uses as if they were interchangeable can obscure their different purposes, decision points, and risks.

What banks may gain—and what the evidence does not show
AI may let firms incorporate new information faster and make better use of available data. If more information is reflected in trading decisions, that could contribute to market efficiency. These are potential benefits, not proof that every AI-supported strategy produces better investment results or that a bank’s risk estimates become more accurate. The Bank of England describes both the possible efficiency benefit and the need for appropriate risk management in its April 2025 assessment.
The cited sources do not quantify an improvement in market-risk accuracy or investment returns, identify a best-performing model or vendor, or provide a bank-by-bank inventory of these systems. A claim that AI reliably boosts returns or reduces risk would go beyond what they establish.

How AI can create market-risk problems
Bad inputs or model flaws can distort exposures
If a model or its data have flaws that are not understood, the resulting exposure estimates may be measured or interpreted incorrectly. A firm could then be less prepared for market stress than its analysis suggests. Model complexity can also make it harder for decision makers to understand the risks they are taking. These are reasons to treat model outputs as something to scrutinize, not as self-validating facts. The Bank of England discusses these risks.
Historical performance may not cover extreme events
A model’s past performance cannot by itself show how it will behave during a shock unlike the events in its historical experience. Radical uncertainty and unprecedented conditions are difficult cases for data-driven systems precisely because the relevant examples may be missing or inadequate. Historical backtests can inform evaluation, but they cannot establish resilience to every future event.
Rank #3
Similar strategies may move markets together
Different firms can end up with correlated positions if their AI strategies converge. Shared data sets, common vendors, or similar models are possible contributors. The scale and systemic consequences of this risk remain uncertain; it is not evidence that all AI systems make the same trades. The Bank of England warns that AI-driven trading and investment strategies could increase the tendency for market participants to take correlated positions. Read its financial-stability analysis.
How to assess an AI-supported approach
There is no evidence in the cited sources that ranks specific AI models or providers. For a practical comparison, focus on the decision the system supports and the controls around it rather than a vendor label.

| What to examine | Questions to ask |
|---|---|
| Purpose and decision point | Is the system used for risk measurement, trading-algorithm calibration, investment insight generation, or another task? Who uses its output, and what decision can it influence? |
| Data quality and coverage | Are the inputs suitable and reliable for the intended use? Could gaps or flaws cause exposures to be misstated? |
| Validation and interpretability | Can the model’s performance and limitations be independently reviewed? Can decision makers understand its output well enough for the decision it informs? |
| Behavior under stress | How is the approach assessed in extreme conditions, especially those not well represented in historical data? |
| Concentration and correlation | Does the approach depend on a common vendor, model, or data set that might contribute to similar positioning elsewhere? |
| Governance and accountability | Who owns the model, defines permitted uses, monitors performance, and decides what mitigants or third-party controls are needed? |
These are evaluation criteria drawn from the supervisory concerns described by the PRA, the Bank of England, and the Financial Stability Board; they are not a published ranking or universal checklist for every use.

What current supervisory guidance says
UK PRA: model risk management for firms within scope
The current version of the PRA’s Supervisory Statement 1/23 was published and took effect on 23 April 2026. It applies to UK-incorporated banks, building societies, and PRA-designated investment firms with specified internal model approvals for credit, market, or counterparty-credit capital requirements. It is not a blanket rule for every bank or every AI application.
Best Value
SS1/23 covers model identification and classification, governance, development and use, independent validation, and mitigants. It calls for applicable AI and machine-learning model risks to be managed within broader model-risk management. The statement’s scope and principles are set out by the Bank of England and PRA.
FSB: proposed practices, not an international standard
On 10 June 2026, the Financial Stability Board published a consultation report proposing 12 sound practices. They span organisation-wide governance, risks across the AI development and deployment lifecycle, and cyber, information and communication technology, and third-party risks. The count refers to proposed governance practices, not evidence that AI is effective.
The FSB explicitly says the practices are not intended to establish an international standard or prescribe adoption of a particular technology. The report is a consultation proposal, not a globally binding rule. See the FSB consultation report.
