Global RTP Volumes Continue Expanding

‍

Global real-time payment transaction volumes are projected to increase from over 260 billion in 2023 to around 575 billion by 2028, according to ACI Worldwide and GlobalData. Over the same period, instant payments are projected to increase their share of global non-cash transaction volume from over 15% to over 20%, according to Capgemini Research reflecting their growing role within digital payment ecosystems.

‍

The expansion of RTP systems reflects broader shifts toward faster settlement, mobile-based payments, and account-to-account transaction models across both consumer and commercial payment environments. RTP infrastructure increasingly supports peer-to-peer transfers, bill payments, payroll processing, and selected commercial payment activities across multiple markets.

‍

Adoption patterns continue to vary significantly by region. India recorded the world’s largest RTP transaction volume at nearly 130 billion transactions in 2023, while Brazil reported the highest year-on-year growth rate at over 75%, supported by the continued expansion of Pix, according to ACI Worldwide and GlobalData. Europe continues developing instant payment infrastructure through SEPA Instant and PSD2 frameworks, while the U.S. market expands through parallel RTP and FedNow systems operating alongside ACH infrastructure.

Multi-Rail Infrastructure Expands Across Payment Ecosystems

‍

The growth of RTP systems is occurring alongside the expansion of increasingly complex multi-rail payment environments. Banks, merchants, and payment providers continue integrating cards, digital wallets, ACH transfers, instant payments, and alternative payment methods within unified payment infrastructures.

‍

According to Capgemini, payment orchestration adoption reaches approximately 70% among PayTech firms, compared to less than 50% among banks. At the same time, ACI Worldwide reports that over 60% of enterprise merchants use orchestration layers to connect with multiple payment service providers and local payment methods. These systems are increasingly used for transaction routing, failover management, reconciliation, and payment optimization across different regions and payment types. Payment providers are also expanding software-based capabilities alongside transaction processing, including fraud management, merchant tools, embedded finance, and operational analytics.

‍

As payment systems become more interconnected, infrastructure complexity also increases. Real-time payment environments require coordinated clearing, settlement, authentication, and fraud monitoring systems operating continuously across institutions and jurisdictions.

A2A Systems Continue Influencing Payment Economics

‍

The expansion of account-to-account payments continues influencing revenue structures across the global payments industry. Card-based payment systems remain linked to interchange, scheme, and processing fees, while many RTP and A2A systems operate with lower or regulated pricing structures.

‍

Real-time A2A payments account for approximately one-quarter of global retail digital payment transactions, while global A2A transaction volumes are projected to increase from 60 billion in 2024 to over 180 billion by 2029, according to Juniper Research.

‍

Merchant payment economics continue to support interest in lower-cost payment rails. Card-based payments often involve higher acceptance and processing costs due to intermediary fee structures, while A2A systems generally operate with fewer intermediaries and simplified cost models. At the same time, payment providers are increasingly generating revenue from software-integrated services rather than relying solely on transaction processing. Demand continues to expand for embedded finance solutions, fraud management capabilities, reconciliation tools, and operational support services integrated within broader payment ecosystems.

‍

Cross-Border Interoperability Remains Limited

‍

Despite strong growth in domestic RTP systems, cross-border interoperability remains limited across many payment environments. Most account-to-account systems continue operating primarily within domestic frameworks, while international transactions remain heavily dependent on correspondent banking and established card infrastructure.

‍

Global cross-border payment volumes continue to expand, reflecting growing international transaction activity across consumers, businesses, and financial institutions. At the same time, interoperability implementation across payment systems remains limited, as many banks continue to express interest in cross-border interoperability while adoption across payment networks progresses more slowly.

‍

Card networks continue maintaining advantages in cross-border transactions through standardized foreign exchange processing, dispute management, and broad international acceptance. In contrast, many A2A systems still lack unified authentication, chargeback, and settlement frameworks across jurisdictions.

‍

At the same time, interoperability initiatives continue developing across selected regions. In Europe, SEPA Instant infrastructure and PSD2 frameworks continue supporting account-based payment environments, while initiatives such as Wero aim to expand pan-European account-based payment infrastructure. Across Asia-Pacific, regional interlinking projects increasingly connect systems such as Singapore’s PayNow, Thailand’s PromptPay, and India’s UPI.

Regional RTP Development Continues Along Different Paths

‍

Regional RTP development continues to follow different infrastructure, regulatory, and market structures. In Europe, instant payment adoption is expanding primarily within retail and lower-value transaction environments, while its role within the broader electronic payments landscape continues to grow alongside regulatory and infrastructure developments.

‍

In the United States, RTP transaction activity continues to expand rapidly as financial institutions and payment providers increase real-time payment capabilities. At the same time, ACH infrastructure remains the dominant framework for account-to-account transactions, continuing to process the majority of payment activity across the market.

‍

India and Brazil remain among the largest and fastest-growing RTP markets globally. India’s UPI and Brazil’s Pix continue expanding through QR-based payment infrastructure, mobile-first payment environments, and interoperable account-based systems supported by central bank and regulatory frameworks. Meanwhile, the Middle East is projected to record some of the fastest RTP growth globally through 2028.

‍

Conclusion

‍

Global payment infrastructure in 2026 reflects continued expansion of real-time payments, account-to-account systems, and multi-rail payment environments across both developed and emerging markets. RTP adoption continues increasing across retail, commercial, and digital commerce environments, while payment providers, merchants, and financial institutions increasingly integrate multiple payment rails within broader payment ecosystems. At the same time, payment infrastructure remains fragmented across regions, particularly in cross-border environments where interoperability, regulatory coordination, and settlement integration continue developing gradually. Card-based payment systems continue maintaining strong positioning in international and credit-linked payment environments, while A2A systems expand primarily across domestic and lower-cost transaction use cases. Looking ahead, payment ecosystem development is expected to increasingly involve infrastructure integration, orchestration capabilities, and software-driven payment services operating alongside transaction processing activities.
