The Dawn of Digital Won: Korea's Most Ambitious Financial Experiment Yet

On March 18, 2026, the Bank of Korea officially launched Phase 2 of Project Hangang, its central bank digital currency (CBDC) initiative, expanding from seven to nine commercial banks and introducing real-world government subsidy disbursement for the first time. This isn't just another fintech pilot—it's a signal that Asia's fourth-largest economy is preparing to fundamentally reshape how 52 million citizens pay, save, and earn rewards.

For anyone invested in the mobile payment and reward app ecosystem, the implications are profound. From slashing credit card merchant fees to enabling instant government benefit transfers, the digital won could upend the very business models that power platforms like Toss, KakaoPay, and NaverPay.

What Is Project Hangang Phase 2?

Project Hangang is the Bank of Korea's framework for testing digital currency infrastructure in real-world conditions. The central bank has carefully positioned the system as "an intermediate stage between a CBDC and stablecoins," emphasizing that it is not premised on the immediate introduction of a full retail CBDC. Instead, it serves as a proving ground for how public financial infrastructure could function in a digital environment.

The nine participating banks now include KB Kookmin, Shinhan, Woori, Hana, NH Nonghyup, IBK Industrial, BNK Busan Bank, plus newly added Kyongnam Bank and iM Bank. Together, these institutions are issuing won-pegged deposit tokens built on a wholesale CBDC layer, designed to handle everything from high-value corporate transactions to everyday consumer payments.

Phase 1, which ran from April to June 2025, provided valuable baseline data: approximately 100,000 participants were invited, 80,000 opened digital wallets, 118,000 test transactions were executed, and 692.46 million won in transaction volume was recorded. Phase 2 introduces significant upgrades including biometric fingerprint authentication, peer-to-peer wallet transfers (a pain point in Phase 1), and automatic top-up functionality from linked bank accounts.

Core Analysis: The Three Pillars of Phase 2

Merchant Fee Reduction

The most commercially significant objective of Phase 2 is reducing payment processing costs for small and medium-sized merchants. BOK leadership has explicitly stated that the pilot will target "small merchants with high public relevance and significant payment fee burdens." In Korea's current system, credit card merchant fees range from 0.5% to 1.5% for small businesses and can exceed 2% for larger establishments. Deposit token-based payments could dramatically simplify this intermediary fee structure.

The banking sector collectively invested approximately 30–35 billion won (roughly $23–27 million) building Phase 1 infrastructure, with LG CNS serving as the core technology partner. Phase 2 will require additional significant investment, though cost-sharing arrangements between the BOK and participating banks remain under negotiation.

Government Subsidy Distribution

For the first time, Phase 2 integrates actual government subsidy disbursement into the digital won framework. South Korea's government is exploring allocating portions of its approximately $499 billion annual budget through this infrastructure—a test case for broader fiscal efficiency improvements. Electric vehicle charging infrastructure subsidies are expected to be among the first use cases, with digital currency disbursement planned for the first half of 2026.

This represents a paradigm shift in public finance. Rather than routing subsidies through complex multi-step administrative processes, funds could be deposited directly into citizens' digital won wallets, reducing administrative overhead and accelerating delivery.

Large-Scale Real-World Testing

Full-scale testing across all nine banks is planned for the second half of 2026, with stated objectives including reducing payment fees for small business owners and building financial infrastructure connected to new industries—including AI-based automatic payments. This timeline positions Korea to potentially move toward commercialization by 2027 if results are favorable.

Impact on Korea's Fintech Giants

The digital won's emergence creates both opportunities and existential challenges for Korea's dominant payment platforms. According to analysis published by Toss, CBDC is more likely to be integrated into existing financial apps as a new payment option rather than replacing them entirely. Users could see digital won appear alongside existing payment methods within Toss, KakaoPay, and NaverPay.

However, the competitive dynamics will shift significantly. If the digital won reduces remittance fees to near-zero, it directly threatens the transaction fee-based revenue models that underpin these platforms. The counterbalance lies in differentiation through value-added services—customized financial products, commerce platform integration, and data-driven personalization.

The market is already pricing in these changes. NH Investment Securities reportedly raised its price target for KakaoPay by 242%—from 38,000 won to 130,000 won—partially based on assumptions about digital currency ecosystem expansion. Meanwhile, Hana Card has launched a competing pilot offering 5% cashback on USDC-funded Visa payments, signaling that private stablecoins are advancing alongside the state-backed digital won.

A critical consideration is the potential impact on bank deposits. If digital won interest rates were set above commercial deposit rates, customers might shift funds toward CBDC holdings, potentially reducing banks' lending capacity. Proper rate management will be essential to prevent destabilizing capital flows.

Reward Apps and App-Tech: A New Paradigm

Korea's reward app ecosystem—led by CashWalk (16 million cumulative downloads), BankSalad, and dozens of smaller platforms—faces a transformative moment. Currently, most reward apps operate on advertising revenue and affiliate marketing models, with point accumulation rates that are modest at best (CashWalk, for instance, offers 1 cash point per 100 steps, up to 100 points daily).

The digital won could reshape this ecosystem in three critical ways. First, point-to-currency conversion could become seamless. Currently, converting reward app points to usable cash involves multiple steps and minimum thresholds. Direct integration with digital won wallets could enable instant, frictionless conversion. Second, merchant fee savings could translate to enhanced consumer rewards. If businesses save 1–2% on payment processing, some portion of those savings could be redirected toward customer-facing cashback and loyalty programs. Third, government subsidy management could become a new core feature for financial management apps like BankSalad, which could offer tools to track, manage, and optimize the use of digitally disbursed government benefits.

How Korea's Approach Differs from China's Digital Yuan

China's digital yuan (e-CNY) remains the world's most advanced CBDC deployment, with 180 million personal wallets and 7.3 trillion yuan (approximately $1 trillion) in cumulative transaction volume. But Korea's approach diverges in several fundamental ways.

Privacy protection is perhaps the starkest difference. China's government can monitor and control all digital yuan transactions, raising significant surveillance concerns. The Bank of Korea has committed to not tracking individual digital currency transaction histories as a core design principle. On operational structure, China uses a dual-tier system led by the People's Bank of China with four state-owned banks as distributors, while Korea is testing a decentralized model where commercial banks issue their own deposit tokens on a shared wholesale CBDC layer. On policy objectives, China aims to internationalize the yuan, while Korea focuses squarely on domestic payment convenience and fee reduction.

These distinctions matter enormously for user trust and adoption. Korea's privacy-first approach may prove more effective at driving voluntary participation in a society with deeply ingrained digital privacy expectations.

Maximizing Value: How to Prepare for the Digital Won Era

For consumers and app-tech enthusiasts looking to position themselves ahead of the curve, several strategies merit consideration. First, secure accounts at participating banks. The nine pilot banks—KB Kookmin, Shinhan, Woori, Hana, NH Nonghyup, IBK Industrial, BNK Busan, Kyongnam, and iM Bank—will be the first to offer digital won wallets. Having accounts ready will ensure early access.

Second, watch for early-mover promotions. When major payment platforms integrate digital won functionality, they will almost certainly offer promotional cashback and rewards to drive adoption—just as Phase 1 attracted 80,000 wallet sign-ups from 100,000 invitations. Early participants consistently receive the most generous incentives.

Third, track government subsidy digitization timelines. If you're eligible for government benefits—EV subsidies, youth housing support, childcare allowances—understanding when these shift to digital won disbursement could help you access funds faster and manage them more efficiently.

Risks and Regulatory Headwinds

Significant uncertainties remain. The Digital Asset Basic Act has yet to pass, creating legal ambiguity around bank-issued tokens. Four related bills are currently pending in the National Assembly, centered on capital requirements for token issuance. The BOK has mandated that won stablecoins be issued only by licensed commercial banks, which could limit fintech companies' direct participation and potentially redirect liquidity to unregulated channels.

The broader crypto market context adds complexity. With concentrated traders controlling over 90% of Korean exchange volume and a 20% stock market decline driving retail investors toward digital assets, the regulatory environment must carefully balance innovation with financial stability.

Conclusion: A Turning Point for Korean Finance

Project Hangang Phase 2 represents far more than a technology experiment—it's the opening chapter of Korea's digital currency future. With nine banks testing real-world deposit tokens, actual government subsidies flowing through digital infrastructure, and explicit goals of reducing merchant fees and enabling AI-powered payments, the digital won is positioned to become a genuine game-changer for Korean finance. The reward app and mobile payment ecosystem that emerges from this transformation may look fundamentally different from today's landscape. For consumers and investors alike, the time to start paying attention is now.
