Indonesia’s Digital Payment Infrastructure Expands: QRIS Growth, BI-FAST and the Next Phase of Cross-Border Payments

From 6.11 Billion Monthly Digital Transactions to New QR Connectivity Initiatives with Hong Kong and Timor-Leste

Indonesia’s digital-payment ecosystem is moving into a new phase. The story is no longer only about whether consumers and merchants are adopting digital payments. The latest evidence points to a broader transition in which domestic transaction scale, national payment infrastructure, and cross-border interoperability are developing together.

Bank Indonesia reported that digital payment volume reached 6.11 billion transactions in August 2026, an increase of 40.36% year-on-year. Within that growth, QRIS transaction volume increased by 67.22% year-on-year, while retail transactions processed through BI-FAST reached 549 million transactions with a value of Rp1,346 trillion.

At the same time, Bank Indonesia is extending the international dimension of Indonesia’s payment infrastructure. On 24 September 2026, Bank Indonesia and the Hong Kong Monetary Authority signed a memorandum of understanding to strengthen cooperation on QR code-based cross-border payments. One day later, Bank Indonesia and Banco Central de Timor-Leste signed a separate agreement that provides a foundation for payment connectivity, including exploration of QRIS Cross-Border between Indonesia and Timor-Leste.

Taken together, these developments suggest that Indonesia’s digital-payment agenda is increasingly operating across three connected layers: domestic adoption, infrastructure capacity, and international interoperability.

Digital Payments Continue to Scale

The latest monthly indicators show that digital transactions remain one of the fastest-growing components of Indonesia’s payment environment.

According to Bank Indonesia’s September 2026 Board of Governors release, digital payment volume reached 6.11 billion transactions in August 2026. This represented growth of 40.36% compared with August 2025.

The growth was broad-based. Internet banking transaction volume increased by 15.12% year-on-year, while mobile banking transaction volume increased by 47.08% year-on-year. QRIS remained particularly strong, with transaction volume growing 67.22% year-on-year.

Verified payment indicators — August 2026

Digital payment volume: 6.11 billion transactions
Digital payment growth: +40.36% yoy
QRIS transaction growth: +67.22% yoy
BI-FAST volume: 549 million transactions
BI-FAST transaction value: Rp1,346 trillion

These figures are important because they show that digital-payment growth is occurring not only at the user-interface level. High transaction volumes also depend on the ability of the underlying infrastructure to process, route, settle, and secure an increasingly large number of transactions.

QRIS Is Expanding in Both Adoption and Strategic Role

During FEKDI x IFSE 2026, Bank Indonesia reported that QRIS acceptance had reached 69.32 million users and 47.11 million merchants as of August 2026.

The numbers reinforce QRIS’s role as national payment infrastructure rather than merely a payment feature. Its relevance now extends across consumer payments, merchant acceptance, financial inclusion, government digitalisation initiatives, and increasingly cross-border connectivity.

Methodological note: the user and merchant figures above are acceptance counts reported by Bank Indonesia. They should not automatically be interpreted as independently verified unique active individuals or continuously active businesses unless the underlying methodology explicitly establishes that distinction.

For ArrezaMP Research, this matters because the analytical question is changing. Earlier stages of QRIS development could be evaluated primarily through adoption. At the current scale, additional questions become increasingly important: infrastructure reliability, interoperability, consumer protection, merchant usability, operational resilience, and whether cross-border expansion produces sustained real-world transaction activity.

BI-FAST Shows the Infrastructure Layer Behind Digital Growth

QRIS is highly visible to consumers and merchants, but retail payment expansion also depends on the infrastructure operating behind the payment experience.

Bank Indonesia reported that BI-FAST processed 549 million retail transactions in August 2026, an increase of 37.72% year-on-year. The value of those transactions reached Rp1,346 trillion.

This provides an important second layer of evidence. Indonesia’s digital-payment transformation is not only a story of more QR codes or more mobile applications. It also requires payment rails capable of processing growing transaction volumes reliably and efficiently.

ArrezaMP analytical framing:
Digital Payment Adoption → Scalable Domestic Infrastructure → Cross-Border Interoperability

This framing is an analytical interpretation used by ArrezaMP Research. It is not terminology formally used by Bank Indonesia.

The Next Expansion Layer Is Cross-Border Interoperability

The latest developments with Hong Kong and Timor-Leste show that payment-system expansion is increasingly international.

Hong Kong: Cooperation Toward QR Interoperability

On 24 September 2026, Bank Indonesia and the Hong Kong Monetary Authority signed a memorandum of understanding on QR code-based cross-border payments.

The agreement establishes a cooperation mechanism covering relevant technical, operational, and regulatory matters. The two authorities will also explore arrangements to facilitate interoperability between QR payment systems in Indonesia and Hong Kong.

The distinction is important: the memorandum is evidence of institutional and technical cooperation. It should not yet be interpreted as evidence that a fully operational Indonesia–Hong Kong QR payment service is already available to all users.

Timor-Leste: A Foundation for Future Payment Connectivity

On 25 September 2026, Bank Indonesia and Banco Central de Timor-Leste signed a memorandum of understanding covering payment and settlement systems as well as digital financial innovation.

Bank Indonesia stated that the agreement provides a foundation for developing payment connectivity between the two countries, including the exploration of QRIS Cross-Border as a potential implementation.

Again, the evidence supports a conclusion about direction and institutional commitment, but not yet about operational usage. Transaction volumes, participating institutions, implementation timelines, fees, foreign-exchange arrangements, and user adoption will require later implementation evidence.

Why Cross-Border QR Connectivity Matters

Cross-border payment interoperability could reduce friction when individuals and businesses transact between countries. A QR-based system can potentially simplify the payment experience by allowing users to interact with familiar domestic payment applications while the underlying infrastructure handles interoperability between jurisdictions.

However, the economic value of such connectivity should not be assumed from the agreement alone. Actual impact depends on implementation quality and usage.

Evidence worth monitoring includes:

when interoperability becomes operational;
which banks and payment service providers participate;
transaction fees and foreign-exchange conversion mechanisms;
merchant acceptance in each market;
consumer-protection and dispute-resolution arrangements;
fraud and cybersecurity controls;
system availability and operational resilience; and
actual cross-border transaction volume and value after launch.

From Payment Adoption to Payment Infrastructure Governance

This development also extends the analytical chain identified in ArrezaMP Research’s previous R2 publication on SPP-TDLN.

That earlier analysis examined how digital-economy governance is moving closer to the infrastructure through which transactions occur. The latest payment-system evidence adds another dimension: the same infrastructure is becoming increasingly important not only for domestic commerce and regulatory administration, but also for international connectivity.

Read the previous R2 analysis: Indonesia’s Digital Economy Enters the Payment-Layer Tax Enforcement Era .

The combined analytical progression can therefore be viewed as:

Digital Economy Growth → Payment Adoption → Payment Infrastructure → Payment-Layer Governance → Cross-Border Interoperability

This does not mean that each stage replaces the previous one. Rather, additional layers of economic activity, infrastructure, regulation, and connectivity are being built on top of an increasingly mature digital-payment ecosystem.

What Businesses Should Watch

For businesses, the most useful signals will come from implementation rather than announcements alone.

The next evidence cycle should monitor:

continued QRIS transaction growth after August 2026;
changes in QRIS user and merchant acceptance;
BI-FAST volume, value, and infrastructure performance;
operational rollout of Indonesia–Hong Kong QR interoperability;
progress toward Indonesia–Timor-Leste QRIS connectivity;
participation by banks and payment service providers;
cross-border payment fees and foreign-exchange arrangements;
consumer protection and cybersecurity developments; and
measurable usage after new cross-border corridors become operational.

These indicators will help distinguish between policy intent, infrastructure readiness, and demonstrated market use.

ArrezaMP Assessment

The strongest conclusion from the current evidence is not simply that digital payments are growing.

Indonesia now has evidence of scale at multiple levels: billions of monthly digital-payment transactions, rapid QRIS growth, hundreds of millions of BI-FAST transactions, and an expanding institutional agenda for QR-based cross-border connectivity.

The structural shift is therefore becoming clearer:

Indonesia’s digital-payment transformation is moving from adoption at scale toward infrastructure at scale — and increasingly toward interoperable regional connectivity.

The evidence is strongest for domestic transaction growth and existing infrastructure usage. Evidence for the Hong Kong and Timor-Leste initiatives is currently at the cooperation and development stage.

That distinction should remain explicit. Memoranda of understanding demonstrate institutional direction and commitment, but they do not yet demonstrate operational transaction performance or economic impact.

For ArrezaMP Research, the next meaningful milestone will not be another announcement alone. It will be evidence that new cross-border connections have become operational, are being used, and are producing measurable improvements in payment accessibility, efficiency, reliability, or economic activity.

Research Note

This Research Update distinguishes between verified official evidence and ArrezaMP analytical interpretation.

The analytical chains “Digital Payment Adoption → Scalable Domestic Infrastructure → Cross-Border Interoperability” and “Digital Economy Growth → Payment Adoption → Payment Infrastructure → Payment-Layer Governance → Cross-Border Interoperability” are ArrezaMP Research frameworks. They should not be read as terminology formally adopted by Bank Indonesia or the partner central banks.

The article does not claim that the Hong Kong or Timor-Leste QR initiatives are already fully operational, nor does it claim that the agreements have already produced measurable economic benefits.
