AI is changing finance through data analysis, forecasting, payments, compliance, and customer services—not just chatbots. It can help institutions work faster and tailor products, but it also creates operational and concentration risks and may amplify existing market vulnerabilities. Current evidence points to expanding use cases and investment plans, not a sector-wide transformation: the available sources do not establish a comparable 2026 AI-adoption rate for banks.
How is AI changing banking and financial services?
AI is being applied to several different kinds of financial work. The Financial Stability Board (FSB) identifies potential benefits including greater efficiency, regulatory compliance, advanced data analytics, and more personalised financial products. Its monitoring report describes possible applications and vulnerabilities across the sector; it does not show that all institutions have deployed AI at scale.
Operations, analysis, and oversight
AI can support processes that involve finding patterns in large datasets, summarising information, or generating forecasts for people to assess. The Bank for International Settlements (BIS), discussing central banks specifically, identifies data analysis, research, economic forecasting, payments, supervision, and banknote production as areas where AI may be used. That list shows the technology’s breadth, but it should not be read as evidence that every central bank—or every commercial bank—uses AI in each area.
Customer-facing services and compliance
Financial institutions may use AI to help personalise products or support regulatory compliance. Those uses can affect sensitive decisions and information, so efficiency is only one measure of success: institutions also need to consider data handling, model reliability, human oversight, and how errors are detected and corrected.

What does current AI investment evidence show?
The European Central Bank’s Survey on the Access to Finance of Enterprises (SAFE), round 39, asked euro-area firms about AI investment they planned for the next 12 months in the April–June 2026 survey period. These are declared plans from firms generally, not completed expenditure or a measure of banking-sector adoption. Respondents could select more than one spending category.
| Planned investment category | Share of firms planning AI investment |
|---|---|
| AI technologies and tools, such as software licences | 49% (ECB SAFE round 39, April–June 2026) |
| Employee training | 46% (ECB SAFE round 39, April–June 2026) |
| Data and infrastructure | 40% (ECB SAFE round 39, April–June 2026) |
| Hiring AI specialists | 12% (ECB SAFE round 39, April–June 2026) |
The categories are not mutually exclusive, so the percentages do not add up to a share of one total budget. They also suggest why AI adoption is not simply a matter of purchasing a model: firms may plan to spend on tools, staff skills, data, infrastructure, and specialist hiring.
How firms planned to finance that investment
Among firms planning AI investment, the ECB reported these intended financing sources. Multiple answers were allowed, and 18% did not select any of the listed options; the percentages therefore should not be added together as if they described a single funding mix.

The survey is useful as evidence of planned investment among euro-area businesses, but it cannot establish how many banks have adopted AI, how much they have spent, or whether the investment has improved productivity.
How should financial institutions govern AI?
Governance needs to cover the system’s lifecycle, from development and data choices through deployment, monitoring, and changes. The FSB’s June 2026 report proposes 12 organisation-wide sound practices for AI governance and management, aimed at boards and senior management and accompanied by implementation case studies. It is a consultation report, not a final binding standard or regulation.
For a financial institution translating governance principles into day-to-day oversight, useful questions include:
- Accountability: Is there a named owner for each AI system, with clear responsibility for its purpose, risks, approvals, and escalation?
- Data: What information enters the system, where is it processed, who can access it, and could sensitive or confidential data be exposed?
- Validation and human review: Has the model been assessed for the task and conditions in which it will be used, and can staff challenge or override its output?
- Monitoring: Are errors, changes in performance, and unexpected outcomes tracked after deployment, with a process to pause or revise the system?
- Suppliers and resilience: Does the institution understand its dependence on external model, cloud, data, or other service providers, including the consequences of an outage or supplier failure?
- Security and response: Are cyber threats and incidents addressed, with a tested route for containment, investigation, and recovery?
These are practical governance implications of the risks identified by the FSB and BIS, not a verbatim list of the FSB’s proposed 12 practices. The BIS guidance is written for central banks: it recommends an adaptive governance framework, ten practical actions, and building on existing risk-management structures such as the three lines of defence. Its central-bank scope matters because those institutions may handle highly sensitive information and play a distinctive role in markets.

Risks can arise inside an institution using AI and across the wider financial system. The FSB’s 2025 monitoring report highlights external-provider dependencies and concentration, market correlations, cyber risks, and challenges in model risk and governance. It also points to monitoring and data gaps as the AI ecosystem and supply chain evolve.
Operational and model risks
A model can produce an unreliable result, behave differently as conditions change, or be used outside the setting for which it was assessed. In its central-bank guidance, the BIS also flags hallucinations, confidentiality and data-security concerns, and reputational exposure. These concerns are especially consequential when outputs influence sensitive work or are presented as authoritative without adequate scrutiny.
Rank #4
Supplier concentration and cyber exposure
Dependence on outside providers can create a common point of failure if many institutions rely on the same service or a small number of suppliers. That is a potential vulnerability, not evidence that a particular provider has failed. Institutions need to account for dependencies and consider how they would maintain important functions during outages, cyber incidents, or a supplier’s loss of service.
System-wide correlations
If institutions use similar models, data, or strategies, their decisions may become more correlated. The FSB identifies market correlations as a vulnerability to monitor; this does not mean AI necessarily causes synchronized trading or a crisis. It does mean that risks should be considered beyond the reliability of an individual model.
Could AI-related investment affect financial stability?
AI can affect financial markets in two distinct ways: institutions may use it in their own workflows, while investors may also finance companies and infrastructure associated with AI. Market concerns about the second category are not proof that AI itself has caused instability.

In its May 2026 Financial Stability Report, the Federal Reserve summarized outreach by Federal Reserve Bank of New York staff to 20 market contacts in March and April, including people at broker-dealers, banks, investment funds, and advisory firms. Contacts raised concerns about AI-linked equity valuations, debt-financed capital spending that could increase leverage, possible labor-market weakness, and disruption to the credit quality of some private-credit borrowers. The report expressly says the survey summary does not represent the views of the Federal Reserve Board or the New York Fed; these are reported concerns, not predictions.
The International Monetary Fund’s April 2026 Global Financial Stability Report examines financing links among listed firms in what it defines as the AI circle. IMF staff reported that, after accounting for broader market effects, average correlation among those firms’ equity returns trended higher from the third quarter of 2025. For the defined group, staff estimated that increased correlation accounted for 7 percentage points of an approximately 12 percentage point cumulative equal-weighted return increase from early September through the end of December 2025, and about $40 billion of the rise in average market capitalisation from a starting base of around $2 trillion.
Those estimates are tied to the IMF’s group definition and late-2025 period; they are not a forecast for all markets. The report discusses circular financing and interconnected firms as possible spillover channels, while noting that core AI firms did not then show the same balance-sheet vulnerabilities as some less systemically important companies elsewhere in the AI ecosystem.

Official sources describe varied potential and current use cases, governance proposals, business investment plans, and risks that authorities are monitoring. Taken together, they support a measured conclusion: AI is becoming relevant to financial operations and investment decisions, but the pace and scale of adoption vary, and the available figures do not prove sector-wide deployment or a demonstrated productivity gain for banks.
