Abstract

Korean Abstract: 본 연구는 가계대출에 대한 다양한 신용정보(가계대출, 다중채무, 신용등급 등)와 시스템적 리스크의 관련성을 검증했다. 분석결과 가계대출 규모는 시스템적 리스크에 선행하는 것으로 나타났다. 특히 은행 가계대출 규모보다는 비은행 가계대출 규모가, 담보대출 규모보다는 신용대출 규모가 시스템적 리스크에 미치는 영향이 더 큰 것으로 나타났다. 또한 다중채무자나 비은행 금융기관의 중상위 신용등급 고객의 대출정보가 시스템적 리스크와 관련이 있는 것으로 나타났다. 본 연구는 개인 신용평가사(Credit Bereau, 이하 CB)가 보유한 개인신용 정보를 이용하여 시스템적 리스크와 가계대출과 관련한 다양한 개인신용 정보와의 관계를 밝혔다는 점에서 의의가 있다. 본 연구결과는 금융시장의 불안정을 나타내는 조기경보시스템 및 시스템적 리스크 측정수단 개발, 또는 거시건전성 정책 수립에 참고자료로 활용될 수 있다.English Abstract: This paper examines the relation between household’s loan information – such as household loans, multiple loan amount and consumer credit ratings ‒ and systemic risk.

家庭贷款和系统风险:信用信息的有用性(Household Loans and Systemic Risk: Usefulness of Credit Information)
Korean Abstract:本研究验证了对家庭贷款的多种信用信息(家庭贷款、多重债务、信用等级等)和系统风险的关联性。分析结果显示,家庭贷款规模先于系统性风险。特别是,非银行家庭贷款规模比银行家庭贷款规模、信用贷款规模比担保贷款规模对系统风险产生的影响更大。另外,多重债务者或非银行金融机关的中上游信用等级顾客的贷款信息与系统风险有关。本研究利用个人信用评价公司(Credit Bereau,以下简称CB)拥有的个人信用信息,表明了系统风险和与家庭贷款相关的多种个人信用信息之间的关系,因此具有重大意义。本研究结果可以作为金融市场不稳定的早期警报系统及系统性风险测定手段的开发,或者宏观健全性政策的树立的参考资料使用。英语Abstract: This paper examines the relation between household ' s loan information - such as household loans, multiple loan amount and consumer credit ratings - and systemic risk。We find that an increase in household loans is a leading indicator of systemic risk。In particular, systemic risk is related more to household loans from non-banks than to those from banks, and more to unsecured loans。This paper also shows that systemic risk is associated with the credit information pertaining to multiple-loan borrowers as well as non-bank borrowers holding medium-to-high credit。This study is distinctive in that the above relationship is verified based on the vast amount of data provided by credit bureaus (CBs)。我们findings could provide some important policy implications for the design of an early warning system, indicating financial market vulnerability, for measures of systemic risk;and for macro - prudential policy。
