Real-time payment (RTP) systems are centralized payment infrastructures operated by central banks, banking consortia, or government-mandated clearing houses that enable domestic bank-to-bank transfers settling within seconds to minutes, 24 hours a day, 7 days a week, 365 days a year — a significant improvement over traditional banking batch processing that limited transfers to business hours and required 1-3 day settlements. The major real-time payment systems globally include: FedNow (United States Federal Reserve, launched July 2023), The Clearing House RTP (US banking consortium, launched 2017), PIX (Brazil, Banco Central do Brasil, launched November 2020), UPI (Unified Payments Interface, India, NPCI, launched 2016), Faster Payments (UK, 2008), SEPA Instant (EU, 2017), and many others across Asia, Africa, and Latin America. These systems are the central banking system’s competitive response to the speed and cost advantages that cryptocurrency and stablecoin advocates have claimed: “why wait 3 days when Bitcoin settles in 10 minutes?” RTP systems answer: “you don’t have to wait — use our bank’s RTP integration.” The emergence of RTP creates competitive pressure on stablecoins for domestic payments (where stablecoin advantages over traditional banking were strongest), while stablecoins retain advantages in cross-border (RTP systems are domestic only), DeFi composability, and censorship resistance. PIX (Brazil) is considered the most successful instant payment system ever deployed — reaching 140+ million users within 3 years, handling $1B+ in daily transaction volume, and largely absorbing what could have been a major stablecoin adoption wave in Brazil.
