South Korean household debt surges in June amid stock market boom

Household lending in South Korea experienced a sharp increase in June, reaching its largest monthly growth since August 2024. According to data from the Bank of Korea, total household loans at financial institutions rose by 7.6 trillion won ($5.6 billion) in June. This expansion was fueled by both housing-related loans and a significant increase in 'other loans,' which include general credit loans and overdrafts.

Housing-related loans saw a rise of 4.3 trillion won, attributed to increased housing transactions in the Seoul metropolitan area and demand for mid-term payments on new housing developments. However, loans for home rentals, known as jeonse loans, continued their decline for the tenth consecutive month, decreasing by 700 billion won.

Considering the usual two-to-three-month time lag between housing sales contracts and mortgage disbursements, the impact of increased transaction volumes before the end of the capital gains tax deferral grace period (May 9) may continue to be reflected in housing-backed loans for some time.

The surge in 'other loans' by 3.3 trillion won is particularly noteworthy, as it is strongly linked to the booming stock market. Individuals have increasingly turned to credit loans to finance their stock investments. This trend raises concerns about the potential for increased household debt volatility and the need for proactive risk management by financial institutions.

Overall bank lending to corporations also increased by 5.1 trillion won in June, though this was a slower pace compared to the previous month. Lending to small and medium-sized enterprises (SMEs) grew by 1.7 trillion won, while large corporations saw an increase of 3.4 trillion won. The financial authorities have urged financial institutions to strengthen household debt management, especially considering the potential lagged impact of increased housing transactions prior to the expiration of a tax incentive and the ongoing risks associated with credit lending.

Preemptive risk management is necessary to prepare for the potential expansion of volatility in credit loans.
