Last month saw a significant surge in household loans, putting the government on high alert regarding household debt management. Although the government has announced that it will keep the growth rate of household debt below the nominal economic growth rate again this year, as it did last year, the faster-than-expected increase in household loans is expected to force policymakers to carefully consider the intensity of future regulations.

Seoul Housing Prices Rise Due to Interest Rate Cuts and Lifting of Land Transaction Permit System, Household Loans Spike

According to industry sources on March 5, household loans across all financial institutions increased by approximately 5 trillion won compared to the previous month, as of the 27th of last month. Looking at February alone, this marks the largest increase in four years since February 2021, when household loans surged due to the prolonged low interest rates following the COVID-19 pandemic (9.7 trillion won). By sector, more than half of the 5 trillion won increase-about 2.61 trillion won-came from the five major banks: KB Kookmin, Shinhan, Hana, Woori, and NH Nonghyup.

The rapid increase in household loans at the beginning of the year is attributed to a combination of factors, including the Bank of Korea's policy rate cuts and the lifting of real estate regulations in Seoul, which led to a rise in property prices in the Gangnam area. The Bank of Korea shifted its monetary policy from tightening to easing by lowering the base rate in October last year. It continued to cut the base rate in November and again in February this year in response to economic sluggishness. Analysts point out that as banks' lending rates began to fall following the central bank's rate cuts, household loans also increased.

In addition, some point out that household loans increased even further when the Seoul Metropolitan Government lifted real estate regulations in the Gangnam area-including Jamsil, Samseong, Daechi, and Cheongdam-on February 12, which had previously been subject to the Land Transaction Permit System. According to the Korea Real Estate Board, apartment prices in Seoul rose by 0.11% in the fourth week of February compared to the previous week, marking four consecutive weeks of increases. The rise was particularly pronounced in areas such as Songpa-gu and Gangnam-gu, which were released from the permit system, and the upward trend is spreading to non-Gangnam areas as well. The Seoul real estate market began to heat up after Mayor Oh Se-hoon actively announced the consideration of lifting the permit system at a citizen forum on January 14, and following the actual removal of the system, housing prices surged in Gangnam, driving up loan demand.

With the speed and scale of household loan growth outpacing last year, the government's concerns are deepening. While financial authorities fundamentally aim to establish a system where household loans are managed autonomously by financial institutions, they also maintain a policy of active intervention when excessive lending threatens to constrain consumption or economic growth, thereby burdening the country as a whole. The authorities are willing to tolerate a certain level of household loan growth in a low interest rate environment, but if the increase becomes excessive, regulatory measures are likely to be strengthened.

DSR System to Be Strengthened, Additional Loan Regulations Expected

The representative regulation is the Debt Service Ratio (DSR). The DSR is the ratio of a borrower's total annual principal and interest payments on all loans to their annual income. Since financial institutions assess all loans-including mortgage loans, unsecured loans, and student loans-by aggregating their principal and interest, the DSR is considered a particularly strict regulation. Banks can only lend to borrowers whose DSR does not exceed 40%. Since the implementation of the current stress DSR, which applies an additional (stress) interest rate, lending has become even more restricted.

Financial authorities plan to tighten household lending by implementing the third phase of the stress DSR regulation starting in July. Under the current second phase, the stress interest rate is set at 0.75-1.20%, but in the third phase, it will rise to 1.50%. In the third phase, the strengthened regulations will apply equally to both banks and non-bank financial institutions. In addition, household loans that were previously exempt from income verification-such as those under 100 million won or used for interim payments or relocation expenses-will now require financial institutions to collect income data and use it to manage DSR-based loan regulations.

Financial authorities note that the specific scope and interest rate levels of the DSR system may be adjusted depending on the real estate market situation and trends in household debt. If signs of overheating appear in the real estate market, DSR regulations could be further tightened, especially in the Seoul metropolitan area. An official from the Financial Services Commission stated, "We plan to finalize the specific scope of DSR application and the level of the stress interest rate in April or May, after reviewing trends in household debt growth and the real estate market."

The Ministry of Economy and Finance will also hold a real estate market monitoring meeting on March 5, chaired by Vice Minister Kim Beomseok and attended by related ministries, to discuss countermeasures. The meeting will review the real estate market situation following the lifting of the permit system and discuss measures to cool down the market, such as tightening loan screening.
