The Dual Nature of Overdraft Accounts: Convenient Yet Risky for Investors

A 30-year-old office worker recently opened an overdraft account, borrowing 30 million won to invest in stocks for marriage and home purchase. While he has made profits from his investments, he faces the pressure of consistently earning more than the monthly interest of 120,000 to 150,000 won. Any fluctuation in stock prices increases his anxiety.

As the stock market thrives, more individuals are engaging in "investment borrowing," with many young people relying on overdraft accounts as a convenient funding source. By the end of May, the total overdraft limit in South Korean banks reached a staggering 130 trillion won.

The primary advantage of overdraft accounts is their convenience. Unlike traditional loans, users can withdraw only the amount they need from a pre-approved limit and pay interest only on that amount. For instance, if a user has a limit of 30 million won but only uses 5 million won, interest is charged only on the 5 million. There are no early repayment fees, and the limit is restored once the borrowed amount is repaid.

However, overdraft accounts are not without risks. Although they may seem like readily available funds, they are still loans. Using them without a plan or leaving them unused for extended periods can lead to unexpected risks. Excessive limits or prolonged use can negatively impact credit scores, as overdraft accounts often carry higher interest rates than standard loans. Failing to pay interest on time can result in late fees and a drop in credit scores.

When seeking additional loans, having an overdraft account can also be detrimental. Financial institutions often consider the overdraft limit as potential debt, which can reduce the amount available for other loans. This means that when applying for a mortgage or other credit loans, the limits may be lower. Recently, stricter regulations on the debt service ratio (DSR) have also made overdraft limits a factor in loan assessments.

Therefore, it is crucial to develop a repayment plan when opening an overdraft account. Due to the flexibility of early repayment, it is easy to end up in a situation where only interest is paid while the principal remains unchanged. However, if credit scores decline or income decreases at the time of annual renewal, the limit may be reduced or renewal denied. If renewal is denied, borrowers must repay their loans quickly, making it essential to consider repayment capabilities alongside investment expectations.
