South Korea’s Stablecoin Rules and Tax Repeal Put Crypto Policy at a Crossroads
South Korea is drafting stablecoin rules and a broader Digital Asset Basic Act while opposition lawmakers try to scrap the country’s planned crypto income tax. Both issues are before the National Assembly this week. Why does this matter? Because investors following Asia need answers to three very practical questions. How will exchanges operate? Who gets to issue won-backed stablecoins? Then there is the bill individual traders may owe. My take: the answers could reshape South Korea’s crypto market.
The Financial Services Commission (FSC) reportedly told the National Assembly on Wednesday that it plans to draft a single Digital Asset Basic Act with the ruling Democratic Party. The bill would cover stablecoin issuance and circulation, plus requirements for digital asset businesses and exchanges. It would also address disclosures, internal controls, and trading system reliability. That is a lot for one law. Maybe too much. Most guides treat one comprehensive bill as the tidy solution. That is only half right. Parliament already has 10 digital asset and stablecoin bills waiting after months of delays, so the alternative is hardly clean. Two disputes are holding things up: whether banks must own a majority stake in issuers of won-denominated stablecoins and whether large crypto exchanges should face ownership caps.
This puts real regulation pressure on South Korea’s crypto market, especially around stablecoins. The mechanics are blunt. A majority bank ownership rule would hand established financial groups a clear advantage and raise the barrier for crypto companies. That is not some footnote. It could determine which won-backed coins reach the market, how easily traders use them, and whether Upbit and Bithumb maintain enough liquidity in related trading pairs. I’ll be honest: ownership percentages matter more here than polished promises about innovation. New rules can move prices fast. Announcements from the US Securities and Exchange Commission have caused affected tokens to fall 5% to 10% within hours. South Korea could see similar jolts if the final bill catches traders off guard.
The tax dispute may hit individual traders sooner. The National Assembly’s Finance and Economic Planning Committee was due to review an opposition bill on Wednesday that would abolish South Korea’s crypto income tax. Under the current plan, annual crypto income above 2.5 million won, or roughly $1,700, would face a 20% levy plus 2% local income tax beginning January 1, 2027. That threshold is low. Really low. People Power Party lawmaker Song Eon-seok introduced the amendment on March 19, removing the provision taxing income from the transfer or lending of digital assets. A separate petition calling for repeal has collected more than 50,000 signatures and is awaiting review. The government and ruling Democratic Party want the tax to proceed. The opposition calls it unfair because most ordinary stock investors pay no similar tax. On May 7, the Finance Ministry said again that it plans to begin collection after several postponements. Counter to the usual framing, this is not simply a pro-crypto versus anti-crypto fight; it is also a dispute over whether two types of retail investor should face different tax treatment.
The outcome will provide an adoption signal, though probably not a clean one. Repeal would likely improve retail sentiment and push more volume onto Korean exchanges. Keeping the tax could deter newcomers because the exemption ends at 2.5 million won. Is that enough to drive traders abroad? Not by itself, but it could help tip the decision. Some may move funds to countries with friendlier rules. Portugal, for example, attracted crypto investors when it generally did not tax gains, while stricter tax systems have sometimes coincided with less trading. Taxes are not the only reason people enter or leave a market. Still, they matter. In my view, the immediate pressure point is demand for won trading pairs and local prices for BTC and ETH. Both sometimes trade above overseas prices, producing the gap known as the “Kimchi premium.”
What this means
Crypto investors have two decisions to follow. First, the Digital Asset Basic Act could end years of uncertainty. That sounds positive. It may also produce restrictive rules. Yes, those points pull in opposite directions, but both can be true. Bank ownership requirements could leave traditional financial institutions controlling most of South Korea’s stablecoin market, affecting DeFi services and reducing how people use crypto in the country. The actual ownership percentages deserve close attention, as do any caps on exchanges. Those figures will tell investors more than another speech about innovation. I would watch them first. They may force Upbit, Bithumb, and other major Korean platforms to change how they operate or limit the assets they list. The final text should also reveal the deeper policy choice: pull crypto into the existing banking system or let independent issuers compete.
The tax repeal is equally important. If the opposition succeeds, Korean traders will avoid a levy that has already been postponed several times, and retail trading may increase. If the tax begins on January 1, 2027, investors with more than 2.5 million won in annual crypto income will need to account for the 20% tax and the extra 2% local levy. Some may trade less. Others could hold assets longer to reduce taxable transactions or move their money abroad. Most commentary stops at the headline tax rate. I think that misses the behavioral part: the 2.5 million won threshold may change when people sell, not merely how much they owe. For now, investors should watch the Finance and Economic Planning Committee’s review and the FSC’s next draft. The details will determine the cost of trading BTC, ETH, and other digital assets in one of Asia’s busiest crypto markets.
