코로나 이후 가계부채의 현황과 위험도 점검

The study presents a comprehensive analysis of household debt issues in Korea, particularly focusing on the post-COVID-19 era characterized by rapid economic changes and increased interest rates. It critically examines the trajectory of household debt since the mid-2000s, emphasizing the period surrounding the 2021 interest rate hike. With household debt becoming a growing concern, especially after the pandemic, its dramatic escalation has been identified as a potential catalyst for economic instability. Notably, the household debt-to-GDP ratio reached a concerning 104.3% in the first quarter of 2022, as reported by the International Institute of Finance (IIF). This elevated ratio, one of the highest globally, underscores the urgent necessity for an in-depth examination of the issue. This study serves the purpose of assessing the current state and risk factors associated with household debt. Despite the absolute high levels of debt, delinquency rates have remained relatively low. However, the research underscores growing concerns about household insolvency in light of the recent abrupt changes in the economic environment, such as rising inflation and interest rates, and the downward trend in the real estate market. These factors could potentially trigger financial instability, heightening the risk of loan defaults and exerting further pressure on the financial system. Employing micro-level data analysis, the research delves into the implications of rising interest rates and economic fluctuations on household debt vulnerability. It highlights the significant impact of excessive household debt on consumer spending and the broader economy, particularly during economic shocks. The study emphasizes the importance of utilizing borrower and household-level data for macroprudential management, as aggregate data alone can be insufficient for a comprehensive risk assessment. The research extends beyond the traditional focus on financial institutions' risks to evaluate the financial vulnerability from the borrowers' perspective. It estimates the changes in the Debt Service Ratio (DSR) due to rising interest rates, examining the likelihood of debt default and the overall increase in debt burden leading to possible consumption contraction. The period of analysis includes both the rapid increase in loans during COVID-19 and the subsequent deleveraging phase due to rising interest rates. By analyzing Credit Bureau data, the research sheds light on the changes in creditworthiness and income distribution among new borrowers during this period. It evaluates the characteristics and distribution of vulnerable debtors and assesses the risk levels across different financial institutions and products. Additionally, the study estimates the increase in interest burden for borrowers during the 2022 interest rate hike, analyzing its impact on consumer expenditure and providing insights into the monetary policy implications of household debt. The conclusion of the study indicates that, overall, the risk to the banking sector from household debt in Korea appears manageable in the short term, despite the increased delinquency rates due to higher interest burdens. The research suggests that while the risk is not significant in the banking sector, it is concentrated in certain non-bank financial institutions, especially those with a high exposure to real estate. The study also explores the regulatory implications and the need for sound management of household debt. It highlights the necessity for realistic adjustments in Loan-to-Value (LTV) ratios and advocates for the implementation of stricter Debt Service Ratio (DSR)-based regulations to ensure financial soundness. Emphasizing the importance of strict adherence to DSR regulations without exceptions, the research underscores the risks associated with relaxing these regulations for the purposes of price stabilization. Such relaxation could undermine the effectiveness of these measures in maintaining financial stability. In summary, the study offers a comprehensive analysis of the dynamics of household debt in Korea, highlighting the importance of macroprudential management to ensure economic stability and resilience. It provides valuable insights into the risks associated with household debt and suggests policy measures for effective risk management and financial stability.
