Global instant payments transaction values reached $22tn in 2024 across 15 major adopting economies and are projected to grow at 15 to 18 per cent annually over the next five years, pressuring traditional revenue pools for commercial banks and payment networks.
According to a study published by McKinsey & Company, infrastructure availability alone does not guarantee market adoption, creating starkly divergent outcomes across global markets.
Divergent Global Adoption Trajectories
India’s UPI and Brazil’s Pix have fundamentally reshaped their domestic ecosystems, with instant transactions accounting for nearly 30 per cent of total transaction volumes in both countries. Mandated bank participation, zero consumer pricing, and digital public infrastructure drove rapid scale. Conversely, the US (RTP and FedNow) and Mexico (CoDi and DiMo) continue to lag due to voluntary adoption, strong card economics, and existing consumer reliance on established payment alternatives like Zelle, ACH, or cash.
Pressure on Traditional Card & Acquiring Revenue
In high-adoption markets, real-time rails have rapidly displaced debit cards and traditional bank transfer slips. To protect profit margins, acquirers and payment networks are shifting strategic focus from processing fees to value-added merchant software, fraud prevention, cash management, and M&A integrations.
Product Innovation to Defend Lending Margins
Banks are adapting to real-time disintermediation by integrating credit mechanisms into instant rails. Innovations such as Brazil’s Pix Parcelado (installment-based instant transfers) and India’s linking of RuPay credit cards to UPI allow financial institutions to preserve high-yield credit products within zero-fee real-time payment flows.
Cross-Border and B2B as Next Frontiers
While consumer peer-to-peer (P2P) payments led early adoption, future volume growth is shifting toward B2B payments, wage distributions, and cross-border connectivity. Domestic networks including the US RTP and FedNow are laying regulatory and operational frameworks to link real-time rails across international borders.
