The credit rating agency Moody's has warned that the financial sector's rapid adoption of artificial intelligence is creating a dangerous systemic dependency on a small group of Silicon Valley tech firms. While AI integration is expected to cut costs, Moody's cautions that a single outage at a major provider could trigger widespread disruptions across multiple banks. Additionally, unprofitable AI developers like OpenAI and Anthropic could exploit their market dominance to raise prices, while automated switching tools risk accelerating deposit flight.
Systemic dependency on AI providers
- ▪Moody's stated that banks can mitigate dependency risks by leveraging proprietary data, negotiating technology contracts, using open-source models, and forming partnerships
- ▪Moody's warned that banks' rapid adoption of artificial intelligence is creating a systemic dependency on a small group of foundation model and cloud computing providers
AI adoption in banking
- ▪Lloyds Banking Group chief executive Charlie Nunn committed to a £13 billion strategy built around artificial intelligence, targeting £2 billion in cost cuts that will affect staff
- ▪Moody's estimated there is a 20 percent probability that artificial intelligence will be capable of performing the work of a solid mid-level employee by 2030
- ▪A UK Treasury select committee report published in January 2026 found that more than 75 percent of financial firms in the City of London were already using artificial intelligence
Vendor pricing power
- ▪Moody's noted that pricing pressure is likely to increase as unprofitable generative artificial intelligence developers, including OpenAI and Anthropic, face investor pressure to deliver profits
- ▪Moody's warned that dominant artificial intelligence model and infrastructure providers could exert control over the prices banks pay for technology services
Data privacy concerns
- ▪Moody's warned that the use of artificial intelligence could increase risks related to data privacy, cybersecurity, fraud, and unexplained decisions made by automated systems
- ▪Moody's warned that artificial intelligence could accelerate deposit flight by making it easier for customers to automatically switch funds to accounts offering higher interest rates
Regulatory scrutiny expectations
- ▪Moody's expects that as artificial intelligence adoption deepens, financial regulators will increase their focus on operational resilience and third-party provider concentration
- ▪HM Treasury proposed an assurance framework in August 2026 to govern third-party artificial intelligence and increase scrutiny of critical technology suppliers
