The Bank of England is considering emergency safeguards for artificial intelligence as officials warn that increasingly autonomous AI systems could one day trigger a major financial market crisis.

In one of its strongest warnings yet on the risks of AI in finance, the UK’s central bank said existing regulations may no longer be enough as advanced AI agents become capable of making trading decisions, executing payments, and carrying out complex financial tasks with little or no human intervention.

Speaking at the European Central Bank’s annual forum in Portugal, Bank of England Deputy Governor Sarah Breeden said regulators are exploring new measures, including market-wide “circuit breakers” or AI “kill switches” that could halt trading if faulty AI systems begin destabilizing financial markets.

The concern is not today’s AI—but what comes next.

While many financial institutions currently use AI for lower-risk functions such as research and operational support, experts believe the technology is rapidly evolving toward fully autonomous “agentic AI” capable of making decisions and acting independently.

Regulators fear that if thousands of AI systems respond to the same market signals at the same time, they could unintentionally amplify volatility, accelerate market crashes, or trigger widespread financial disruption during periods of economic stress.

According to a recent survey by the Cambridge Centre for Alternative Finance, more than half of financial firms are already using some form of agentic AI, suggesting the technology is moving into mainstream finance faster than many expected.

The Bank of England also warned that AI is expanding beyond trading. Future AI agents may authorize payments, manage investments, identify cyber vulnerabilities, and complete financial transactions on behalf of consumers—raising difficult questions about accountability, fraud prevention, and regulatory oversight.

The warning reflects a broader shift among global regulators. Organizations including the Financial Stability Board have increasingly called for stronger safeguards as AI systems become more powerful and autonomous, arguing that traditional financial regulations were never designed to oversee machines capable of making independent decisions at scale.

For investors, banks, and consumers, the message is clear: artificial intelligence has the potential to transform global finance, but without the right guardrails, the same technology could also introduce new systemic risks.

As AI adoption accelerates across the financial sector, regulators around the world are racing to ensure that tomorrow’s intelligent trading systems remain an asset—not the trigger for the next financial crisis.
