저축은행 예수부채비율이 경영위험에 미치는 영향 ：저축은행 규모와 소재지역을 중심으로

[Purpose]The purpose of this study was to analyze the effect of deposit leverage ratio household loan on savings bank management risk. In addition, by categorizing by size and local areas, the effect of the deposit leverage ratio on management risk was confirmed. [Methodology]The empirical analysis period is from June 2014 to June 2018, and results were derived using a probability effect model for 79 savings banks. [Findings]The analysis results are as follows. First, as a result of estimating the relationship between the savings bank management risk and the deposit leverage ratio, the greater the equity－to－deposit ratio, the greater the management risk. Second, It was estimated that there is a difference in the management risk between large savings banks and small and medium－sized savings banks. The larger savings banks were found to have higher management risk, but the larger savings banks were found to have a lower management risk when the proportion of equity capital to deposits was higher. Third, it was estimated that there is a difference in the management risk of savings banks in the metropolitan area and local savings banks. Savings banks in the metropolitan area showed greater risk of management, but when savings banks in the metropolitan area had a greater share of equity capital compared to deposits, the risk of management decreased. [Implications]The implication is that if the leverage exceeds an appropriate level, it is necessary to recognize that the burden of interest expenses increases and management risks increase, and the deposit leverage ratio should be maintained at an appropriate level.
