European financial regulators gathered in Sintra, Portugal this week to confront a growing problem. Artificial intelligence is advancing so quickly that the rulebook cannot keep up. The traditional process of writing financial regulations takes years. AI models now improve in weeks or months.
Nikhil Rathi, CEO of the UK's Financial Conduct Authority, put it bluntly. "Technology moves incredibly fast, and we need to think differently about some of the innovations that we are seeing on AI."
Rathi's comments came during the ECB's annual meeting, held the week of July 3, 2026. The meeting highlighted a tension between innovation and safety. Regulators want to encourage AI adoption but fear they are losing control.

The Sintra gathering, an annual event hosted by the European Central Bank, has become a key venue for debating the future of financial regulation. This year, the rapid ascent of generative and agentic AI dominated discussions. Officials acknowledged that while the technology can boost productivity and efficiency, its ability to operate autonomously and at scale introduces unprecedented systemic risks. The dialogue reflected a global consensus: existing frameworks, designed for slower-moving technological change, are ill-equipped to handle the current pace.
She noted that officials have talked about cybersecurity risks like hacking and data theft for about a decade. "But with the acceleration and deepening of AI models, we are confronted with a much more serious risk, because it is happening very, very quickly, and because the means of defense - and the funding required for them - have yet to be found."
Bank of England Deputy Governor Sarah Breeden pointed to an emerging threat: agentic AI. This is artificial intelligence that can take actions on its own, not just generate text or images. Currently, trading firms mainly use autonomous AI in low-stakes functions like research activities.
"But that could change quickly," she said. Breeden warned, "Agentic AI could amplify volatility during bouts of market stress."
European policymakers are not just worrying - they are planning. ECB Vice-President Boris Vujčić stated that Europe needs to build its own AI expertise. "Europe is now in a situation where… it has to, of course, develop its own capabilities in the AI sphere."
Rathi added that regulators do not want to block adoption but need transparency about risks. "We don't want to stand in way of adoption but we need to be transparent about where risks lie."
