Korea’s crypto market faces tax fight, trading slump, and USDT laundering crackdown
South Korea’s cryptocurrency industry is entering a politically sensitive stretch as investors, exchanges, and regulators confront a mix of tax uncertainty, shrinking trading volumes, and growing scrutiny over crypto-linked money laundering.
At the center of the debate is the government’s plan to begin taxing crypto gains in January 2027 after three previous delays. Under the current plan, annual crypto profits exceeding 2.5 million won ($1,650) would be taxed at 22%. The framework was first formalized in 2020, but implementation was postponed several times amid concerns over investor protection, market readiness, and political resistance.
According to the Hankyoreh newspaper, opposition has intensified after lawmakers scrapped the country’s financial investment income tax, which would have applied to gains from stocks and funds. Critics argue that taxing crypto while most retail stock investors remain exempt from capital gains tax creates an uneven playing field.
Crypto tax petition advances
A public petition calling for the abolition of crypto taxation has already gathered more than 54,000 signatures, clearing the threshold for review by a National Assembly committee. The petitioner argued that the issue needs a full reconsideration, including the possibility of scrapping the tax altogether.
The opposition People Power Party has also proposed legislation to abolish the crypto tax, saying it would be inconsistent to impose a separate income tax on crypto assets after eliminating the broader financial investment tax. The ruling Democratic Party, meanwhile, is expected to take up the issue more seriously after the June 3 local elections.
The government says there has been no change to its position and that crypto taxation is still scheduled to begin next January. But it has ruled out, at least for now, any renewed discussion on the financial investment income tax, fueling claims that the tax system is treating crypto investors unfairly.
The tax dispute comes as Korean crypto exchanges are already grappling with a steep drop in trading activity. Retail investors have been shifting money into equities, drawn by a strong KOSPI rally and momentum in chip and AI stocks, draining activity from the crypto market.
According to CoinMarketCap data cited by ETNews, Upbit’s average daily trading volume in the first quarter stood at about $1.55 billion, down 38.8% from the second half of last year. Bithumb’s first-quarter daily average was roughly $647 million, a 44.4% drop over the same period.
The decline continued after the first quarter. From Jan. 1 to May 20, Upbit’s average daily volume fell to about $1.38 billion, down 45.5% from the second half of 2025. Bithumb’s average dropped to about $600 million, widening its decline to 48.5%.
That slowdown has hit earnings. Dunamu, the operator of Upbit, reported first-quarter operating revenue of 234.6 billion won and operating profit of 88 billion won ($58 million), down 55% and 78% year-on-year, respectively. Bithumb posted revenue of 82.5 billion won ($55 million) and operating profit of just 2.9 billion won ($2 million), down 57.6% and 95.8%, while swinging to a net loss of 86.9 billion won ($58 million).
The structural problem is that Korean exchanges still rely heavily on retail spot-trading fees. Unlike major global exchanges, domestic platforms have limited room to expand into derivatives, institutional custody, stablecoin payments, and other higher-margin businesses. Rising compliance costs, including customer verification and anti-money-laundering (AML) upgrades, are adding to the burden.
USDT dominates $77M laundering case
Separately, Korean police said they apprehended 149 suspects accused of laundering about 117 billion won ($77.5 million) through a network linked to a China-based laundering group in Shenzhen, according to the Seoul Economic Daily. Seven suspects were formally arrested, and police said all suspects identified so far are Korean nationals.
USDT accounted for 72% of the funds moved, while bogus gift-card operations made up 19% and ordinary bank transfers 9%. Authorities said the scheme used accounts opened under other people’s names and overseas crypto exchanges to make the funds harder to trace.
Meanwhile, sentiment among Korean crypto investors remains mixed but not entirely bearish. A weekly survey by CoinNess and Kratos found that 34.1% of respondents expected Bitcoin to rise or surge this week, while 36.3% expected sideways movement and 29.6% expected a decline.
Asked whether the crypto market could recover this year, 38.5% said the current downturn looked like a healthy correction with room for a rebound, while 29.7% said the market would not only recover but also set new highs. Combined, 68.2% of respondents expected some form of recovery this year.
Still, pessimism remains. Another 17.7% said the crypto market had peaked and was unlikely to rebound, while 14.1% said they had already left the market and no longer had expectations.
At the time of publication, Bitcoin (BTC) was trading at $76,677.43, up 0.1% over the past week, reflecting a largely range-bound market.
