Instant payments reached nearly $22 trillion across the top 15 adopting economies in 2024, representing about 1% of the roughly $2 quadrillion in global payment flows. According to an August 2026 report by McKinsey & Company, the value of instant payments is expected to expand by 15% to 18% annually over the next five years. However, global take-up remains starkly uneven, with emerging markets like India and Brazil driving rapid consumer and business adoption, while mature economies like Mexico and the United States lag behind.
India and Brazil have established world-leading real-time payment ecosystems through strong regulatory mandates and zero-fee structures. India’s Unified Payments Interface, launched in 2016 following the 2010 rollout of IMPS, now processes over 19 billion monthly transactions and accounts for nearly a third of all national payments, fueled by merchant subsidies, interoperable mobile apps, and the 2016 demonetization policy. Similarly, Brazil’s central bank introduced Pix in 2020 with mandatory bank participation and zero consumer fees, allowing it to capture nearly 30% of total transaction volume and 40% of small business sales. Brazilian lenders are now expanding Pix into installment financing, challenging traditional credit cards while 95% of large corporate clients plan to increase its usage.
In contrast, adoption in Mexico and the United States remains low due to entrenched payment habits and fragmented bank participation. Despite Mexico’s SPEI-backed CoDi and DiMo systems, instant payments comprise under 5% of overall transaction volume, as cash remains the primary method for a third of consumers and only 18% regularly use mobile tap-to-pay or QR codes. In the United States, The Clearing House’s RTP network processed 447 million transactions in 2025 while the Federal Reserve’s FedNow handled 8 million—a minuscule share of the nation’s 345 billion annual payments—leaving bank-backed Zelle to dominate private peer-to-peer flows with 4.2 billion transactions. As a result, McKinsey expects instant payments in mature markets to serve primarily as business treasury, liquidity, and embedded finance tools rather than fully replacing established card networks.
