Thailand’s banking sector crossed a threshold in June 2025 that few believed would arrive so quickly. The Bank of Thailand approved three virtual banking licenses (commonly referred to as digital banks), authorising consortiums led by SCB X, Krungthai Bank and Ascend Money to establish digital-only banks targeting the nation’s substantial underbanked population. With operations required to commence by June 2026, this sets the stage for the most significant competitive disruption Thailand’s financial services industry has witnessed in decades.
The approvals represent more than regulatory housekeeping. They signal Thailand’s calculated bet that technology-native banks can reach segments traditional institutions have struggled to serve profitably, whilst simultaneously forcing incumbents to accelerate digital transformation they might otherwise have delayed for years.
The Winners and What They Bring
The three approved consortiums reveal careful regulatory thinking about which combinations of capital, technology and distribution could succeed in Thailand’s competitive market.
SCB X, parent company of Siam Commercial Bank, partnered with South Korea’s KakaoBank and China’s WeBank – two of Asia’s most successful digital banking operators. The consortium brings established banking infrastructure combined with proven digital banking expertise from markets that have already navigated this transition.
Krungthai Bank’s consortium includes Advanced Info Service (AIS), Thailand’s leading telecommunications provider with 46.3 million mobile subscribers, and PTT Oil and Retail Business, which operates extensive convenience store networks. The combination offers immediate distribution reach to millions of potential customers through existing touchpoints.
Ascend Money, operator of the TrueMoney e-wallet with over 32 million users, secured approval alongside backing from Ant Group. The CP Group connection provides access to Thailand’s most extensive retail network, including over 15,000 7-Eleven stores – physical touchpoints that could differentiate their digital offering.
The Market Opportunity
Thailand’s financial services landscape combines high formal banking penetration with persistent underbanked segments – a paradox these digital banks are designed to address. A substantial portion of Thailand’s adult population remains either unbanked or underbanked, representing the target market digital banks aim to capture through digital-first propositions tailored to demographics traditional banks have found difficult to serve profitably.
Digital payment infrastructure has developed rapidly. The PromptPay system, launched in 2017, enables instant peer-to-peer transfers and has achieved widespread adoption. Mobile and internet banking reached 144.3 million accounts by October 2024, processing more than 6.28 billion transactions, according to Bank of Thailand data.
This infrastructure provides the foundation digital banks need. Rather than building payment rails, they can focus on layering lending, savings and wealth management products atop existing real-time payment systems.
How Incumbents Are Responding
Thailand’s established banks haven’t waited passively. Major institutions have accelerated digital transformation investments, recognising that defensive positioning requires more than incremental improvement.
Kasikornbank announced a $2.7 billion strategic programme in July 2022 aimed specifically at boosting access among Thailand’s unbanked and underbanked populations, small businesses and self-employed individuals. The bank’s partnership with LINE to offer social banking services through LINE BK leverages LINE’s 56 million monthly active users in Thailand – providing distribution reach that matches or exceeds what digital banks can immediately achieve.
CEO Kattiya Indaravijaya characterised KBank’s initiative as combining the strengths of a heavyweight traditional lender with the DNA of a challenger bank to empower a whole new generation. “We’re taking a bold step and, through technological leadership, aim to transform banking in Thailand in ways that can help more people enter the banking system and benefit from banking products and services,” she said.
Siam Commercial Bank announced a major core system overhaul in 2024, partnering with Sunline to replace decades-old infrastructure. The four-year integration project positions SCB as what executives describe as a “full-fledged digital banking” leader by completion. “This is the first IT architecture revamp in over a decade. The partnership will enable SCB to quickly offer tailored financial solutions and seamless experiences to individual customers and corporate clients, setting a new benchmark for the finance industry on both the domestic and global levels,” said CEO Kris Chantanotoke.
David Becker, managing director for Asia Pacific at Mambu, captured the competitive dynamic: “A lot of us think that the virtual banks coming in 2026 will be cloud-first, cloud-native. That’s a given. They will be agile, customer-centric from the start, and will set a new bar for speed and innovation. The opportunity for the incumbents is still there, if they can execute in the right way.”
The Profitability Question
Digital banking’s economic viability remains unproven in Southeast Asia. Across Asia-Pacific, regulators have licensed numerous digital-first banks yet few have reached profitability quickly. The transition typically requires three to eight years, according to industry analysis.
Hong Kong’s eight digital banks, licensed since 2019, have made significant market inroads but most remain distant from reporting net yearly profit. Singapore’s digital banks face similar timelines.
Thailand’s approved digital banks hold one advantage: only three licenses were granted, compared to eight in Hong Kong and multiple approvals in Singapore. Reduced competition could accelerate the path to profitability by allowing each entrant to build meaningful market share before fragmentation occurs.
The consortiums’ structures suggest awareness of this challenge. By combining established customer bases – telecommunications subscribers, e-wallet users, retail touchpoints – with digital banking expertise, they’re attempting to shortcut the customer acquisition costs that have burdened purely digital entrants in other markets.
Regional Implications
Thailand’s approach differs meaningfully from other Southeast Asian markets. Singapore licensed digital banks with explicit mandates to serve SMEs and underserved segments. Malaysia’s digital banking licenses emphasised financial inclusion for underbanked populations. Indonesia’s digital bank approvals focused on extending services to the archipelago’s geographically dispersed population.
Thailand’s framework sits somewhere between. The consortiums approved combine technology sophistication with established distribution networks – a hybrid model that could prove more sustainable than purely digital approaches elsewhere in the region.
If successful, Thailand’s model could influence regulatory thinking across Southeast Asia, potentially leading to similar hybrid licensing approaches in Vietnam, Philippines and other markets considering digital banking frameworks.
What Determines Success
Customer acquisition costs in competitive markets have plagued digital banks globally. The approved consortiums’ access to existing customer bases through telecommunications, e-wallets and retail networks could mitigate this challenge; or prove insufficient if traditional banks successfully defend relationships through improved digital offerings.
Technology execution will separate winners from also-rans. Cloud-native architectures, AI-driven underwriting and seamless user experiences aren’t merely nice-to-haves but competitive necessities. Digital banks that launch with clunky interfaces or limited product sets will struggle regardless of capital backing.
Regulatory evolution will shape the playing field. If the Bank of Thailand concludes initial approvals succeeded in expanding financial inclusion, additional licenses could follow. If concerns emerge about stability or consumer protection, regulatory constraints could tighten.
For Thailand’s financial services industry, the introduction of digital banks represents an inflection point. Whether they ultimately reshape the competitive landscape or become niche players absorbed by incumbents depends on execution over the next two to three years.
What’s certain is that Thailand’s banking sector in 2028 will look markedly different from 2024, and the transformation began with those three approvals in June 2025.
