Cambodia Digital Payment Growth 2020-2026: Bakong, KHQR, and Mobile Money Trends

The trajectory of Bakong transaction volumes tells the story of Cambodia's payment transformation. In its first full year of operation (2021), Bakong processed approximately 1.2 million transactions worth USD 2.1 billion. By 2022, that figure had tripled to 3.8 million transactions as banks completed integration and KHQR gained traction. The inflection point came in 2023, when NBC mandated KHQR interoperability across all licensed institutions, driving volumes to 11.8 million transactions worth USD 18.5 billion. The 2024 figures showed continued acceleration: 21 million transactions worth USD 26 billion, representing a 78% year-over-year increase in volume. Preliminary 2025 data suggests the system is on track to exceed 24 million transactions and USD 30 billion in value. The average transaction size has decreased from USD 1,750 in 2021 to approximately USD 1,250 in 2025, indicating broader retail adoption beyond the initial corporate and high-value use cases.

KHQR has been the critical demand-side driver of Cambodia's digital payment growth. Before KHQR standardization, merchants needed separate QR codes for each bank and wallet provider, creating confusion and friction. The NBC launched the KHQR standard in 2022 based on EMVCo specifications, mandating that all licensed payment institutions adopt the unified protocol. Merchant registrations grew from 50,000 at launch to 180,000 by end of 2023, accelerating to 350,000 by end of 2024 and exceeding 400,000 by early 2025. The geographic distribution shows concentration in Phnom Penh (52% of registrations) and Siem Reap (14%), with secondary cities like Battambang, Kampong Cham, and Sihanoukville accounting for the remainder. The NBC has set a target of 600,000 registered merchants by end of 2026, with a specific focus on rural market vendors and micro-enterprises through simplified registration processes.

Cambodia's mobile money ecosystem predates Bakong, with providers like Wing (Cambodia) and TrueMoney establishing significant user bases before 2020. The GSMA reports that registered mobile money accounts in Cambodia reached 21.3 million by end of 2024, up from 12.7 million in 2020. Given Cambodia's adult population of approximately 11 million, this implies an average of nearly two accounts per adult, reflecting the multi-provider nature of the market. Active accounts (defined as at least one transaction per 90 days) tell a more nuanced story. The 90-day active rate improved from 31% in 2020 to 48% in 2024, meaning approximately 10.2 million accounts were actively used. The most common transaction types shifted dramatically: person-to-person (P2P) transfers dropped from 72% of transactions in 2020 to 45% in 2024, while merchant payments grew from 8% to 31%, reflecting the KHQR-driven shift toward commercial use cases.

Cross-border payment corridors represent the next growth vector for Cambodia's digital payment infrastructure. The Bakong-PromptPay linkage with Thailand, operational since mid-2023, has been the most impactful. The ADB estimates that the Thailand-Cambodia remittance corridor handles over USD 1.5 billion annually, with approximately 1.2 million Cambodian migrant workers in Thailand sending regular remittances home. Prior to the Bakong-PromptPay link, the average cost of sending USD 200 from Thailand to Cambodia was approximately 10% of the transaction value through informal channels and 6-8% through licensed remittance agents. The bilateral QR linkage reduced this to under 5%, saving an estimated USD 75-100 million annually for migrant workers. The Malaysia-Cambodia DuitNow-Bakong corridor, launched in 2024, serves approximately 250,000 Cambodian workers in Malaysia and is expected to process USD 400 million in remittances annually.

The World Bank Global Findex data reveals the scale of Cambodia's financial inclusion gains. In 2017, only 36% of Cambodian adults had made or received a digital payment. By 2021, this figure reached 55%, and by 2024 it climbed to 73%. This 37-percentage-point increase over seven years represents one of the fastest financial inclusion trajectories in the developing world. The gender gap in digital payment usage also narrowed significantly. In 2017, the gap between male and female digital payment usage stood at 14 percentage points (43% male vs. 29% female). By 2024, this had narrowed to 6 percentage points (76% male vs. 70% female), driven by mobile money agents in rural areas and simplified KYC processes. The rural-urban divide similarly compressed from 28 percentage points in 2017 to 12 percentage points in 2024, with rural adoption reaching 65% compared to 77% in urban areas.

The commercial opportunity embedded in Cambodia's digital payment growth is substantial. CamFinTech estimates the total addressable market for payment processing fees, value-added services, and related fintech solutions at approximately USD 180-220 million annually by 2025. This includes merchant discount rates averaging 0.5-1.0% on card and QR transactions, payment gateway fees for e-commerce integration, and cross-border transaction margins. The payment revenue pool is growing faster than transaction volume because higher-margin segments are expanding. E-commerce payments, which carry gateway fees of 2.5-3.5%, grew from 3% of digital transactions in 2020 to an estimated 12% in 2025. Similarly, cross-border payments, which generate FX margins of 0.5-1.5%, expanded from 5% to 15% of Bakong value over the same period. The NBC's push to bring informal cash transactions into digital rails represents an additional addressable market estimated at USD 8-12 billion in currently undigitized retail payments.

Cambodia's digital payment market features three distinct competitor categories, each with different strengths. Commercial banks, led by ACLEDA Bank, ABA Bank, and Canadia Bank, dominate the Bakong ecosystem with a combined 68% share of Bakong transaction volume. Their advantage lies in existing customer relationships, regulatory compliance infrastructure, and direct Bakong API access as Tier 2 participants. Fintech companies, including payment aggregators and e-wallet providers, captured approximately 22% of transaction volume in 2024, up from 12% in 2022. Wing (Cambodia), backed by South Korea's Cellcard, remains the largest non-bank payment provider with over 8 million registered accounts. TrueMoney, backed by Thailand's Ascend Group, follows with 4.5 million accounts. Telecom-led mobile money services account for the remaining 10%, with Smart Axiata's SmartLuy being the most prominent. The trend favors fintech players gaining share, particularly in merchant acquisition and value-added services.

Based on current trajectory data and NBC policy signals, CamFinTech projects that Cambodia's digital payment ecosystem will reach several critical milestones by end of 2026. Bakong transaction volumes are expected to exceed 30 million annually, with total value surpassing USD 38 billion. KHQR merchant registrations should approach the NBC's target of 600,000, driven by the General Department of Taxation's CamInvoice mandate which creates a compliance incentive for merchant digitization. Three structural shifts will shape the 2026 landscape. First, the completion of ASEAN cross-border QR payment linkages will enable five or more bilateral corridors, transforming Cambodia from a remittance-receiving economy to a regional payment hub. Second, the integration of CamInvoice with Bakong payment data will create a unified commercial transaction record, enabling new credit scoring models for SME lending. Third, the entry of regional super-apps and digital banks, attracted by Cambodia's open infrastructure, will intensify competition and accelerate innovation in embedded finance, insurance, and credit products.
