Korea's CBDC Pilot Scales to 500,000 Users With Government Money on the Rail
South Korea's Financial Services Commission designated Project Hangang Phase 2 as an innovative financial service on July 15, expanding the CBDC pilot to 500,000 users with live government subsidy disbursements and programmable spending rails.
South Korea's Project Hangang Phase 2 is infrastructure for programmable state money, and it just got official cover to run indefinitely.
Key takeaways
- South Korea's Financial Services Commission officially designated Project Hangang Phase 2 as an "innovative financial service" on July 15, 2026, clearing nine banks to issue deposit tokens to up to 500,000 users, with live large-scale transactions planned for September.
- Phase 2 moves real government money through the system for the first time, starting with EV charging subsidies, and introduces biometric payments, P2P wallet transfers, and AI-triggered automatic payments with no fixed end date.
- Phase 1 reportedly cost 30 to 35 billion won in infrastructure to clear less than 700 million won in transactions, with 42.1% of distributed funds actually spent. Those numbers do not describe a fee-reduction program.
South Korea's Financial Services Commission designated Project Hangang Phase 2 as an "innovative financial service" on July 15, 2026, authorizing a sandbox expansion of the Bank of Korea's two-tier CBDC pilot to nine commercial banks and a hard cap of 500,000 deposit-token users. The BOK's own framing leaves little ambiguity: per a Bank of Korea official, "From the second phase, we will lay the groundwork for commercialization", the speaker was not named in available reporting.
What Phase 2 Actually Adds
Phase 2 is structurally different from Phase 1 in ways that matter. Per the FSC designation statement via Bloomingbit, the new feature set includes: biometric payments, person-to-person wallet transfers, AI-based automatic payments, smart-contract-enforced spending rails, and higher holding and transfer limits. Two banks, Kyongnam and iM Bank, join the original seven participants including KB Kookmin, Shinhan, Woori, Hana, NH Nonghyup, IBK Industrial, and BNK Busan.
The architecture is a two-tier system: the BOK issues wholesale CBDC exclusively to commercial banks, and those banks issue "deposit tokens" backed by that CBDC to retail users. Consumers never hold the wholesale instrument directly. The BOK retains settlement authority over every retail flow.
Phase 2 also introduces government subsidy disbursements for the first time, starting with EV charging infrastructure subsidies, with a pilot ministry to be selected in consultation with the Ministry of Finance and Economy. Phase 1 had no fixed end date problem to resolve because it was time-boxed. Phase 2 has no end date at all.
One technical constraint worth noting: the wholesale CBDC ledger and Korea's existing BOK-Wire+ real-time gross settlement system are not linked in real time. Per Governor Shin Hyun-song's paper "Realizing the Unified Ledger: Lessons From Project Hangang," presented at the ECB Forum on Central Banking 2026, the system operates as a transitional arrangement with the two ledgers reconciled offline rather than joined in real time, with balance snapshots taken at 3:00 p.m. the following business day. That is a material operational gap for a system the BOK is positioning as commercialization-ready.
The Math the BOK Isn't Highlighting
Phase 1 ran from April through June 2025. Roughly 80,000 wallets were opened against a 100,000-user cap. The system processed 114,880 transactions.
Only 42.1% of distributed funds were actually spent, per the HRF CBDC Tracker citing Korea Times reporting. Total transaction volume stayed below 700 million won.
Infrastructure cost: reportedly 30 to 35 billion won, per multiple secondary sources.
That is a roughly 50-to-1 cost-to-throughput ratio. The BOK reviewed those numbers and declared Phase 1 a success, then expanded the program. No payment efficiency argument survives that math.
The Russia digital ruble rollout follows an identical playbook: mandate participation through the banking sector, frame it as modernization, let the architecture mature before the policy questions get asked. Korea is further along the "voluntary" phase, which is precisely when the architecture is hardest to resist.
The programmability angle is where Phase 2 diverges most sharply from Phase 1. Smart contracts and AI-triggered automatic payments are explicitly part of the Phase 2 feature set. The EV charging subsidy pilot is the template: the government decides what the money is for, and the money enforces it.
The BOK's stated intent for government subsidy disbursements includes restricting the use of funds to streamline administrative costs, per the HRF CBDC Tracker. Technically, there is nothing in Phase 2's architecture that prevents spending conditions from being extended beyond subsidies. No Korean law currently prohibits it.
Once government payments flow through a CBDC rail, opting out carries a cost. You can decline to use the deposit token system, but if subsidy disbursements, and eventually broader public sector payments, run exclusively through that rail, declining means forfeiting access to those funds. Voluntary becomes mandatory without a mandate ever being passed. The UK surveillance infrastructure trajectory and France's DAC8 decree both followed the same pattern: build the monitoring capacity first, legislate the compulsion later.
The U.S. Senate included a provision in the 21st Century ROAD to Housing Act, passed 85 to 5 on June 22, 2026, barring the Federal Reserve from issuing a retail CBDC through December 31, 2030. President Trump has not yet signed it. Korea is not waiting to find out what happens next. The BOK is already planning a tokenized government bond pilot for 2027 built on the same wholesale CBDC infrastructure.
What to Watch Before September
The BOK plans to begin live large-scale transactions in September 2026. The key signal to watch is which ministry gets selected as the first government subsidy disburser and what spending conditions, if any, are attached to those tokens at launch. If restrictions are embedded from the first government disbursement, the commercialization path becomes considerably harder to route around.
Project Hangang Phase 2 is the operational proof of concept for programmable state money at consumer scale. The trigger that disproves it is equally specific: if Korea's legislature passes binding, enforceable privacy protections explicitly prohibiting transaction monitoring and spending conditionality on deposit tokens, and those protections are applied against the BOK and FSC, then this is a genuine payments modernization story.
The Digital Asset Basic Act, currently stalled on stablecoin issuer disputes, contains no such protections. Nothing in the current legislative pipeline does.

Frequently Asked Questions
The BOK issues wholesale CBDC only to commercial banks. Banks then create "deposit tokens" backed by that wholesale CBDC and distribute them to retail users. Consumers never hold the wholesale instrument. The BOK retains settlement authority over all retail flows through the two-tier structure, preserving the existing banking intermediary layer while giving the central bank visibility into every transaction the system processes.
Yes, technically. The programmability of smart contracts in Phase 2 makes spending restrictions straightforward to implement. The BOK's stated intent for government subsidy disbursements explicitly includes restricting use of funds to streamline administrative costs. No South Korean law currently prohibits the BOK or FSC from attaching conditions to how deposit tokens are used after disbursement.
The U.S. Senate passed a provision barring the Federal Reserve from issuing a retail CBDC through December 31, 2030, as part of the 21st Century ROAD to Housing Act (85 to 5 vote, June 22, 2026). President Trump has not yet signed the bill into law. Korea, by contrast, is planning live government subsidy disbursements through its CBDC infrastructure in September 2026 and a tokenized government bond pilot for 2027.
