摘要

摘要本研究探讨了资本、市场风险和银行流动性状况之间的关系。在估计SVAR回归模型时,采用格兰杰因果关系、脉冲响应函数和预测误差方差分解对结果进行估计。数据样本包括2009年至2018年期间的商业银行。实证结果表明,流动性冲击是由结构性冲击共同引起的。格兰杰因果关系、脉冲响应函数和预测误差方差分解表明,从长期来看,对市场风险的敏感性是影响银行业流动性状况的关键因素。此外,实证结果表明,资本充足率在短期内对流动性状况的影响最小。改革市场风险敏感性政策、资本充足率政策和流动性政策措施可以成为减少流动性短缺和避免银行资不抵债的宝贵政策工具。

An Empirical Analysis of the Relationship Between Capital, Market Risks, and Liquidity Shocks in the Banking Industry
Abstract This study explores the relation between capital, market risks and banks’ liquidity conditions. In estimating the SVAR regression model, Granger causality, impulse-response functions and forecast error variance decomposition were employed and used for estimation of the results. The data sample comprised of commercial banks over the 2009 to 2018 period. The empirical results showed that liquidity shocks are caused by a combination of structural shocks. The Granger causality, impulse-response functions and forecast error variance decomposition documented that sensitivity to market risk is the key factor affecting liquidity conditions in the banking sector in the long run. In addition, the empirical results showed that capital adequacy has minimal impact on liquidity conditions in the short run. The reforming rate to sensitivity to market risk policies, capital adequacy policies and liquidity policy measures can be valuable policy tools to minimize liquidity shortages and avoid insolvent banks.
