Abstract
In the Basel III Accord issued by the Basel Committee on Banking Supervision (BCBS) in 2010, banks’ liquidity risk management is included into Pillar I from Pillar II and is subject to quantitative supervision thereafter. The Committee has developed two minimum liquidity standards, which are Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR). Based on the Basel III framework for liquidity risk measurement, we attempt to get the two liquidity standards for 9 Taiwanese systemically important banks via public information. Even though the Basel III Accord has implemented the so-called microprudential regulation to measure liquidity risk for every individual bank, to some extent, it neglects the macroprudential measures. Hence, we make references to Chung (2011) attempting to build up a systemic risk model with credit risk, interbank contagion risk and liquidity risk involved altogether. By modifying several parameters such as deposits’ run-off rates and banks’ insolvency hurdle rates, we make the scenario analysis of multi-risk losses for 7 Taiwanese domestic banks. The empirical assessment shows that while the LCRs and NSFRs meet the supervisory requirements, or higher than 100%, for the 9 sample banks, they differ a lot with each other. Notwithstanding comparable business among banks, their operating strategies really differ. In addition, we find out that the higher the banks’ NSFRs are, the less likely they are to suffer from liquidity loss. Similarly, the higher the banks’ LCRs are, the more resilient they will be to survive the stressed events such as 2008 financial crisis. Under our reasonable assumptions, the scenario analysis helps to evaluate the financial health for the 7 sample banks and understand how the loss distribution and the VaRs change taking credit risk, interbank contagion risk and liquidity risk into account.
