The World Bank’s Global Findex 2025 surveyed approximately 148,000 adults across 141 economies, providing evidence on financial access, payments, mobile ownership, and digital financial services.
Fast payment systems can also help governments distribute payments and financial assistance more efficiently.
For developing economies, this infrastructure can become a foundation for broader digital financial services rather than simply another way to transfer money.
Real Time Payments in Emerging Markets
Emerging markets have played an important role in the development of fast payment systems.
India is a major example. The World Bank reported that India’s UPI ecosystem processed approximately 59 billion transactions between July and September 2025. In 2024, UPI processed around 172.2 billion transactions.
The same World Bank analysis found that fast payments represented 45% of digital payment volume in 11 Latin American and Caribbean countries in 2024, compared with only 2% in 2017.
These numbers show how quickly real time payments can scale when infrastructure, consumer adoption, merchant acceptance, and interoperability develop together.
Challenges of Real Time Payments
Despite their advantages, real time payment systems also introduce important challenges.
Fraud and Scams
Instant transactions can create a difficult security problem: legitimate payments need to be fast, but suspicious transactions also move quickly.
Fraudsters may attempt to exploit social engineering, fake identities, account takeovers, or fraudulent payment requests.
This makes real-time fraud detection and customer education essential.
Operational Reliability
A payment system that operates 24/7 cannot rely on long maintenance windows.
Banks and payment operators need highly resilient infrastructure, backup systems, monitoring, and incident-response procedures.
A major outage can affect millions of transactions within a short period.
Irreversible Transactions
Some instant payment systems make transactions difficult or impossible to reverse once completed.
This can be useful for finality and certainty, but it also means customers need to verify payment information carefully before confirming a transfer.
Cybersecurity
As payment infrastructure becomes more connected, the potential attack surface also increases.
Payment providers need strong authentication, encryption, access controls, monitoring, and security governance.
The World Bank has highlighted that the increasing scale of instant payment infrastructure can also create opportunities for bad actors to conduct fraud and scams at scale.
The Future of Real Time Payments
The next stage of real time payments will likely focus on interoperability and international connectivity.
Domestic instant payment systems are already operating in many countries, but connecting those systems across borders is more complicated.
BIS Project Nexus aims to connect domestic instant payment systems through standardized infrastructure. According to BIS, connecting instant payment systems could allow cross-border payments to reach recipients within 60 seconds in most cases.
In 2025, India, Indonesia, Malaysia, the Philippines, Singapore, and Thailand incorporated a legal entity called Nexus Global Payments to move the Project Nexus concept toward live implementation.
This could eventually make international transfers feel more similar to domestic instant payments.
Real Time Payments and ISO 20022
Another important development is the adoption of modern financial messaging standards.
ISO 20022 provides a standardized way for financial institutions and payment systems to exchange structured payment information.
Better payment data can improve:
- Transaction processing
- Compliance
- Fraud detection
- Reconciliation
- Cross-border interoperability
- Automated financial reporting
BIS’s 2025 cross-border payment monitoring found that adoption of ISO 20022 and APIs was progressing across payment systems, with many systems already processing or planning to adopt ISO 20022 messages.
Conclusion
Real time payments are becoming one of the most important developments in modern financial infrastructure. They allow money to move faster, support 24/7 transactions, improve convenience, and create new opportunities for consumers and businesses.
The global numbers show how quickly the technology is expanding. More than 120 fast payment systems were operating by 2024, while fast payment transactions reached 266 billion in 2023, growing by more than 42% in a single year.
However, speed alone does not make a payment system successful. The next generation of real time payments will need to combine speed with security, reliability, affordability, interoperability, and strong consumer protection.
