April 17 (Asia Today) — Corporate loan delinquency rates in South Korea are rising three times faster than household debt, increasing pressure on banks as lending expands, financial data showed Thursday.

According to the Financial Supervisory Service, the delinquency rate on corporate loans at domestic banks reached 0.76% at the end of February, up 0.09 percentage points from a month earlier and 0.08 points from a year earlier.

By comparison, the household loan delinquency rate rose 0.03 percentage points from the previous month to 0.45%, highlighting a much steeper increase in corporate defaults.

The corporate delinquency rate marked its highest level in nine months. Small and medium-sized enterprises recorded a rate of 0.92%, with small corporations at 1.02% and sole proprietors at 0.78%, indicating rising stress across the sector.

Delinquency rates among large corporations also increased, reaching 0.19% – the highest level in 28 months – suggesting that financial strain is spreading beyond smaller firms.

The trend comes as banks expand corporate lending under policies aimed at boosting “productive financing.” Outstanding corporate loans at the country’s five major commercial banks totaled about 859.8 trillion won ($573 billion) as of the end of March, up roughly 15.0 trillion won ($10 billion) in three months.

Loans to small and medium-sized enterprises accounted for about 79% of the total, while large corporate loans made up about 21%.

Regulators said rising delinquencies are most pronounced among smaller firms but warned that broader economic uncertainty could push default risks higher across the corporate sector.

Banks are responding by tightening risk management while maintaining lending growth. Major lenders are strengthening oversight from initial loan screening to post-loan monitoring, using systems such as early warning tools and AI-based credit assessments to identify high-risk borrowers.

Industry officials said the combination of expanding corporate lending and rising delinquency rates is rapidly increasing the burden on banks to maintain asset quality.
