Seoul Regulators Unleash Warnings on Upbit & Bithumb’s Crypto Lending Schemes—Is DeFi’s Future at Stake?
South Korean regulators just dropped a regulatory hammer on two crypto giants—and the echo could shake the entire DeFi landscape.
The Crackdown Begins
Upbit and Bithumb, Korea’s top crypto exchanges, now face intense scrutiny over their lending products. Seoul’s Financial Services Commission (FSA) claims these platforms might be flirting with unlicensed securities offerings—a move that could spell trouble for yield-hungry investors.
Why This Matters
Crypto lending isn’t new, but regulators are done playing nice. The FSA’s warning signals a broader squeeze on high-yield products that promise ‘safe’ returns in a market that’s anything but. Remember Celsius? Yeah, they do too.
The Irony of Crypto ‘Innovation’
Banks get flak for their 0.1% savings rates, but when crypto offers 10%, suddenly it’s ‘too good to be true.’ Funny how that works. Either way, Seoul’s watchdogs aren’t laughing—they’re circling.
What’s Next?
If history’s any guide, expect tighter rules, ‘voluntary’ service suspensions, and a fresh wave of FUD. But for crypto? Just another Tuesday.
Growing Regulatory Compliance for Crypto Lending and Margin Trading Services
Bithumb initiated its cryptocurrency lending service on July 4, allowing users to borrow digital assets using their existing cryptocurrency holdings or Korean won as security, offering leverage ratios up to 4:1.
The service encompasses 10 digital currencies, including Bitcoin, Ethereum, Ripple, and Tether.
Coinciding with Bithumb’s launch, Upbit rolled out a comparable lending platform supporting three cryptocurrencies: Tether, Bitcoin, and Ripple. The platform is similarly collateralized by crypto assets or traditional currency deposits.
These platforms allow traders to borrow cryptocurrencies they don’t possess and execute short sales, generating profits when asset values decline, essentially creating short-selling mechanisms within the VIRTUAL asset marketplace.
Financial authorities have expressed strong concern that these exchanges may be contravening Korea’s Lending Business Act through their high-risk operations. They particularly pointed out Bithumb’s 4:1 leverage ratio, which surpasses the 2:1 leverage limitation established for Korea’s traditional equity markets.
Ki Young Ju, a Seoul-based crypto investor and founder of CryptoQuant, has also noted the dangerous nature of excessive margin trading, particularly when leverage exceeds 4:1 ratio.
In a recent social media post, Ju emphasized that utilizing leverage above 5:1 exponentially increases the probability of liquidation within a 24-hour period, noting:
“Bitcoin moved more than 2% on most days (82%) this month. If you play 50x Russian roulette every day, the chance of surviving a week is only 0.000612%.”

Bithumb responded by modifying its service framework while preserving its 4:1 leverage structure. The exchange has temporarily suspended new lending applications due to an exhausted lending inventory.
The FSC and FSS are planning to establish an industry collaborative task force to develop voluntary self-regulatory guidelines for cryptocurrency lending and margin trading operations.
South Korean Crypto Firms Grow From Gambling Status to Corporate Ventures
These developments occur amid a series of investment sector restrictions as Seoul regulators prioritize consumer protection measures.
On July 23, the FSS advised asset management companies to avoid “excessive inclusion” of cryptocurrency-related stocks such as Coinbase and MicroStrategy in their ETF portfolios.
However, some regulatory constraints may be reconsidered as South Korea considers reclassifying cryptocurrency trading and brokerage operations as “venture companies,” a designation that WOULD provide access to government subsidies, tax benefits, and financial assistance programs.
Current legislation, implemented in 2018, specifically prevents blockchain-based cryptocurrency firms from obtaining venture certification, categorizing them alongside gambling establishments and entertainment venues.
The proposed regulatory amendment seeks to reverse this classification, potentially legitimizing the country’s expanding digital asset industry.

— Regulation Asia (@RegulationAsia) July 31, 2025Venture company status in South Korea provides numerous advantages, including tax reductions and enhanced access to government-backed financing programs.
These benefits were previously denied to crypto firms, as demonstrated by Dunamu, Upbit’s parent company, which incurred an $18 million corporate tax liability following the revocation of its venture certification
