Instant Payments Break the Card Tollbooth
Real-time account-to-account networks are reaching enough consumers and merchants to challenge cards for everyday payments. Regulation and open-banking standards are accelerating adoption by making instant transfers ubiquitous and easier to initiate at checkout. Wallets and payment platforms that can monetize commerce around these rails gain share, while card networks and legacy acquirers face slower volume growth and fee compression. This is a bank-rail disruption story, distinct from cryptocurrency or stablecoin adoption.
