Malaysia Advances ASEAN's First 24/7 RTGS System — Here Is What It Means for Regional Payments

The Facts

Malaysia has advanced the operational deployment of ASEAN's first 24/7 Real-Time Gross Settlement system — a milestone that elevates Malaysia's payment infrastructure to a level matching the most advanced payment systems globally. RTGS systems enable large-value interbank transfers to settle in real time around the clock, eliminating the overnight settlement windows that previously created liquidity risk and operational complexity for financial institutions.

The significance of 24/7 operation is substantial. Traditional RTGS systems operate during defined business hours on working days — meaning a payment initiated on Friday afternoon might not settle until Monday morning, creating a multi-day exposure window for the sending institution. Around-the-clock operation eliminates this window, enabling financial institutions to manage liquidity more efficiently and enabling new use cases like real-time corporate treasury operations and same-day cross-border business payments.

The Philippines' payment infrastructure has simultaneously reached a different milestone: InstaPay, the country's instant payment rail for retail transactions, recorded 4.6 billion transactions in 2025 — a threefold increase from 1.4 billion in 2024. E-wallets now serve over 70 million Filipinos, representing penetration of the majority of the adult population in a market that was significantly unbanked a decade ago.

Technical Deep-Dive

RTGS architecture processes each payment instruction individually and irrevocably as it arrives — "real-time" refers to settlement finality, meaning the receiving institution's account is credited immediately and the transaction cannot be reversed once settled. This is distinct from deferred net settlement systems, where individual transactions are netted against each other and a single net position is settled at defined intervals.

The 24/7 extension requires operational changes beyond simply keeping the payment engines running. Liquidity management becomes continuous rather than day-end — financial institutions must maintain sufficient reserves to cover outgoing payments at any hour, rather than managing daily net positions. System maintenance and software updates must be scheduled around payment flows rather than during overnight windows.

Cross-border integration is the next layer of complexity. The Nexus infrastructure, being architected with Endava, aims to link ASEAN countries' domestic instant payment rails into a unified cross-border system. The technical challenge is substantial: each country's system uses different message formats, settlement currencies, liquidity pools, and regulatory requirements. Nexus provides a translation layer that enables domestic payment systems to interoperate without requiring each to be rebuilt.

The ASEAN Perspective

The combination of Malaysia's 24/7 RTGS and the Philippines' InstaPay growth tells a regional story: ASEAN's payment infrastructure has reached a tipping point where digital payment capabilities are beginning to match the economic opportunity. The infrastructure that was being built over the past decade is now operational and scaling.

For Singapore businesses transacting with Malaysian counterparts, the 24/7 RTGS availability means that MYR settlements can be executed outside traditional banking hours — reducing the cash flow management complexity of cross-border trade financing. The SGD-MYR payment corridor is one of the highest-volume in ASEAN, and settlement speed improvements compound significantly across annual transaction volumes.

The Nexus cross-border integration project is the most significant medium-term development to monitor. If ASEAN's major instant payment systems — PayNow (Singapore), DuitNow (Malaysia), PromptPay (Thailand), and InstaPay (Philippines) — achieve genuine interoperability, the cost and speed of regional cross-border payments will improve dramatically for SMEs that currently use correspondent banking or money transfer operators.

RECATOOLS Verdict

ASEAN's payment infrastructure is converging toward a regional standard where instant, low-cost, 24/7 payments are the baseline expectation for consumers and businesses. The domestic rail improvements (Malaysia's RTGS, Philippines' InstaPay growth) are prerequisites for the cross-border integration (Nexus) that will genuinely change the economics of intra-ASEAN trade.

For businesses operating across ASEAN borders, the payment landscape in 2026 is meaningfully better than it was in 2023, and the trajectory is clear. The remaining bottleneck is cross-border regulatory harmonisation — the technical infrastructure is largely in place.
