Deposit Insurance Premiums and Bank Risk
利用监管数据和保险费率表中的拐点，估计存款保险费率对银行资产组合调整的影响，发现费率提高会削弱银行对准备金的需求、增加短期银行间贷款供给，为最优存款保险定价提供参考。
Abstract Deposit insurance premiums impose costs on banks’ balance sheets, narrowing profit margins and inducing banks to “search for yield.” This paper estimates the effects of deposit insurance premiums on bank portfolio rebalancing using supervisory data and a kink in the insurance premium schedule. We show that deposit insurance premiums weaken banks’ demand for reserves (a liquid asset with no credit risk) and strengthen the supply of short-term interbank loans (a less liquid asset with credit risk). We discuss the implications of these findings for optimal deposit insurance pricing.
