Artificial intelligence has already disrupted search, software, and customer service.
The next frontier is more consequential and less visible: the core infrastructure that moves money around the world
Governments and financial institutions are increasingly treating AI not as a tool to improve existing systems but as the foundation for building entirely new ones. That shift is beginning to reshape how banking, payments, compliance, and cross-border settlement actually work. Finance is becoming AI’s most important real-world deployment Financial systems are particularly attractive for AI deployment because they already depend on structured processes, repetitive workflows, and constant coordination between institutions.
Compliance screening, fraud detection, identity verification, payment routing, treasury management, and credit assessment all involve the kind of high-volume decision-making that AI systems are designed to accelerate. McKinsey’s review projects AI will drive up to 20% in net cost reductions for banks, with agentic AI expected to have the most significant operational impact. Sota Watanabe, CEO of Startale Group, said the shift is happening because modern financial systems already depend on exactly the kind of real-time coordination AI is built for. “Governments are starting to treat AI the same way they once treated the internet as national infrastructure,” Watanabe said.
