Bank of Korea's Stablecoin Ban: A Flow Analysis of the Won's Digital Future

The Bank of Korea has drawn a clear line in the sand. In a report issued on February 23, 2026, it urged that only licensed commercial banks be allowed to issue won-backed stablecoins, framing a bank-led consortium as the primary path forward. This official stance directly confronts a powerful market momentum that has already begun to flow. The catalyst is the pending Digital Asset Basic Act, expected to pass within the first quarter of 2026, which has triggered a race between traditional bank alliances and agile fintech giants.

The market's counter-move has been swift and decisive. The first official won-backed stablecoin, KRWQ, has launched on the Fraxtal blockchain and is already moving substantial liquidity. It has surpassed 5 billion won in cumulative volume across key DeFi pairs, establishing a direct on-chain corridor between the domestic won and global digital finance. This launch is a direct attempt by private actors to capture a massive, unregulated flow of liquidity that the central bank is trying to contain and control.

The setup is now a classic regulatory stalemate. The government aims to pass the legalization bill, while the central bank pushes for a narrow, bank-dominated model. Meanwhile, the market is already building its own infrastructure, with five banking giants forming an alliance and Kakao running a rival task force. The flow of capital and innovation is moving faster than the policy debate, creating a volatile environment where the official framework may struggle to keep pace with the reality of the market.

The Liquidity War: Banks vs. Fintech

The battle for the next wave of won-denominated liquidity is now a direct infrastructure war. The stakes are the massive, high-velocity flows of retail payments and cross-border settlement that could migrate to a digital layer. The central bank's push for a bank-led model is meeting a rival alliance forming around big tech firm Kakao, creating a clear divide between traditional finance and agile fintech.

The bank-led consortium is moving fast. Five banking giants, led by Hana Financial Group, have joined an alliance to create a special-purpose company for issuing a won-pegged coin. Their plan is to build a system with 100% reserves, aiming to capture the flow of domestic currency by converting local funds into a stablecoin. This project is explicitly designed to align with the central bank's preferred model of a bank-dominated consortium, positioning them to be first in line for any legal change.

On the other side, fintech giants are building their own on-ramps. Naver Pay, Kakao Pay, and Toss are developing stablecoin integrations, targeting the colossal retail payment flows that already move through their platforms. Kakao is running a dedicated task force and reportedly working on a Kakao-branded won-pegged coin. This rival path aims to leverage existing user bases and digital ecosystems to capture liquidity from the start, bypassing the traditional banking gate.

The outcome will determine which ecosystem controls the flow. The bank alliance seeks to redirect existing settlement and treasury flows into a regulated, capital-intensive model. The fintech path aims to siphon off retail transaction volume and new digital money creation, potentially creating a parallel system. The war is for control over the next layer of the won's digital future.

Catalysts and Risks: The Flow's Next Destination

The immediate catalyst is the government's plan to pass the legalisation bill next month, which will lift the nine-year ban on domestic token issuance. This legislative event is the key trigger that will allow either the bank-led consortium or the fintech alliance to launch their won-pegged coins. The flow of capital and innovation is now waiting for this green light to move from planning to execution.

The primary risk is a regulatory stalemate, as seen in a recent pause on the next big crypto law due to disagreements on issuance control. The Bank of Korea's insistence on a bank-dominated model clashes with the Financial Services Commission's push for a more flexible approach. This impasse could delay the bill's final passage, freezing the market's momentum and allowing the current unofficial flow-like the KRWQ stablecoin already moving 5 billion won-to solidify a parallel system outside the official framework.

The real-time signal will be the first major volume spike. Watch which infrastructure wins: a bank-issued coin targeting treasury and settlement flows, or a fintech-issued coin leveraging existing retail payment rails. The winner will control the next wave of won-denominated liquidity, determining whether the digital future is built by traditional finance or agile tech.
