Interest Rate Hikes Dampen Expectations for Lower Borrowing Costs

Borrowers who increased their loans in anticipation of lower interest rates are now facing a backlash. With the likelihood of interest rate hikes growing, those who recently purchased homes using mortgage loans, known as the "young-gul" generation, are expected to experience increased repayment burdens.

On June 2, financial authorities reported that Lee Hyun-sung, the Governor of the Bank of Korea, stated the day before, "All indicators, including housing prices, household debt, and exchange rates, point in the same direction," indicating that there is sufficient room for monetary policy adjustments.

Market observers interpret this as a signal for potential interest rate increases. Rising housing prices, expanding household debt, and exchange rate instability all contribute to the need for tightening monetary policy to ensure price stability and financial security. The Governor's simultaneous mention of these indicators suggests a perception that there are few constraints on raising interest rates.

Financial analysts predict that the Bank of Korea may raise the benchmark interest rate twice in the second half of this year, potentially increasing it from the current 2.50% to 3.0% by year-end, and possibly reaching as high as 3.25% in early next year.

A significant concern is that much of the funding that has flowed into the housing market recently was predicated on expectations of interest rate cuts. As the U.S. adopts a more accommodative monetary policy and domestic economic slowdown concerns grow, many had anticipated lower borrowing costs.

According to the Bank of Korea, the outstanding balance of household loans at the end of the first quarter was 1,865.8 trillion won, an increase of 12.9 trillion won from the end of the previous year. Of this, housing-related loans accounted for 1,178.6 trillion won, making up 63.2% of total household debt.

Notably, the increase in loans is shifting from banks to non-bank financial institutions. While the growth of housing-related loans from commercial banks has slowed, loans from mutual finance, Saemaul Geumgo, and credit unions have expanded. This indicates that demand for housing purchases and loans continues despite stricter regulations in the banking sector.

When interest rates rise, the first to feel the impact are borrowers with large loan amounts. The "young-gul" generation, in particular, is sensitive to interest rate fluctuations. An increase in the benchmark rate leads to higher market and loan rates, exacerbating repayment burdens.

Financial experts believe that if interest rate hikes materialize, the burden will quickly escalate for borrowers with variable-rate loans. Fixed-rate loans that reach maturity are also likely to incur higher rates during renewal or refinancing processes.

Kim Dae-jong, a professor at Sejong University, stated, "The trend of rising benchmark rates will quickly translate into higher lending rates from commercial banks, putting significant pressure on the 'young-gul' generation with high debt service ratios (DSR)." He added, "It is essential to adopt a conservative approach focused on reducing debt and securing cash flow rather than aggressive asset expansion. Furthermore, measures such as expanding fixed-rate refinancing loans should be considered to prevent a chain of defaults among vulnerable borrowers."
