South Korea to Tighten Borrowing Rules Amid Debt Concerns

South Korea will enforce stricter borrowing rules from July to curb rising household debt, the Financial Services Commission (FSC) announced. The move comes as the Bank of Korea signals further interest rate cuts this year.

The FSC will tighten stress debt-to-service ratios (DSRs), a rule first introduced in February 2024 and reinforced in September, to account for fluctuations in borrowing costs. The aim is to limit household debt growth to 3.8%, aligning with the country’s projected nominal GDP expansion and stabilizing the household debt-to-GDP ratio at 90.5%.

With South Korea’s household debt reaching 1,927.3 trillion won ($1.34 trillion) by the end of 2024—the fastest rise in 2.5 years—the government is reinforcing its stance on debt control. The country already has some of the world's most complex borrowing rules, particularly for mortgage loans, which factor in both income and property values by region.

The policy shift coincides with the Bank of Korea's recent rate cut to 2.75%, with expectations for one or two more reductions this year. Despite easing monetary policy, the FSC remains firm on preventing excessive borrowing, citing economic uncertainty and an unpredictable real estate market.

As one of the most heavily indebted economies, South Korea’s financial authorities are walking a fine line—balancing economic stimulus through lower interest rates while tightening lending regulations to prevent financial instability.
