South Korean Loan Shark Sentenced After Charging Interest Rates as High as 6,083%
A South Korean appeals court has sentenced an unlicensed moneylender to three years and six months in prison in a case involving annual interest rates reaching 6,083%, threatening collection practices and a borrower who died by suicide after experiencing debt collection activity.
The Seoul Northern District Court’s 3rd Criminal Division reduced the defendant’s original four-year sentence by six months while describing the nature of the offenses as serious. The case provides an extreme example of the illegal lending and collection practices South Korean authorities have sought to combat through recently strengthened consumer financial protection laws.
Appeals Court Reduces Prison Sentence
The defendant, identified in Korean media reports by the surname Kim, was prosecuted for operating an unregistered lending business and collecting interest substantially above South Korea’s legal limits between July and November 2024.
According to reports on the appellate decision, the operation charged annualized interest rates ranging from 1,233% to 6,083%.
The court found that the collection conduct included threatening messages and abusive communications directed at borrowers as well as their relatives and acquaintances.
One borrower, a woman in her 30s who was raising a young daughter, died by suicide in September 2024 after experiencing collection activity. Reports said she left a suicide note.
The appeals court said the collection methods inflicted significant psychological and financial harm on victims, pointing to the frequency and duration of the conduct, the magnitude of the interest rates and the nature of the threats.
Despite those findings, the court reduced Kim’s sentence from four years to three years and six months. The court considered his partial admission of the offenses, expressions of remorse and additional settlements reached with victims during the appeal.
Prosecutors had sought an eight-year prison sentence.
South Korea Has Strengthened Protections Against Illegal Lending
The case comes amid a broader crackdown on illegal private lending in South Korea.
Under reforms implemented in 2025, certain lending agreements involving annual interest above 60% can be treated as antisocial illegal loan contracts, making both principal and interest unenforceable. Contracts involving violence, threats or certain prohibited debt collection provisions can also qualify for invalidation.
South Korea’s Financial Services Commission said the reforms were designed to deprive illegal lenders of financial gains and provide stronger protections for financially vulnerable borrowers. The government also substantially increased potential criminal penalties for operating an unregistered lending business and violating maximum interest-rate requirements.
The country’s current regulatory framework generally caps covered lending rates at 20% annually. By comparison, the rates attributed to Kim reached more than 300 times that threshold.
