Blockchain technology offers one path to that goal, but only if systems can connect. Citi has built its own tokenized platform and linked it to its broader banking network, including a 24/7 U.S. dollar clearing system with more than 300 banks. Still, Rugg emphasized that internal upgrades alone are not enough.

“This is another tool in the toolkit,” he said, adding that banks must also modernize traditional infrastructure and connect it with digital systems.

The broader industry faces fragmentation. A growing number of banks, fintech firms and crypto projects are building separate networks, often using different standards. That risks recreating the same inefficiencies blockchain aims to fix.

Rugg argued that shared infrastructure — built “for the industry, by the industry” — will be key to scaling tokenized finance, citing models such as Swift’s global messaging network.

At the same time, regulation remains a constraint. Large banks require clear legal frameworks before rolling out new products. “Unless it is 100% permissible, we are not going to do that,” Rugg said.
