Coinbase CEO Brian Armstrong warned that banks failing to adopt stablecoins and crypto infrastructure will be “left behind” as the financial system evolves. He said Coinbase is already working with several major U.S. banks on pilots involving stablecoin payments, trading and crypto custody, signalling growing institutional acceptance. Armstrong argued that stablecoins offer faster, cheaper and more efficient payment rails compared to traditional systems, and banks that embrace them will gain long-term advantages. He added that regulatory clarity and rising global adoption make stablecoin integration increasingly necessary for banks aiming to stay competitive in the next wave of digital finance.
