COVID-19 and the Health of Banking Sector in Japan and South Korea : A Comparative Study

The economies of Japan and South Korea are dominated by banks. Both countries have created a complex financial structure, including a well-established banking industry at their heart that supports economic operations. However, both countries’ banking sectors have previously faced crises such as the Asian Financial Crisis (mostly in South Korea), the Japanese economic slowdown, and the financial crisis of 2007-08 (both). While the Bank of Japan (BOJ) approved the quantitative easing (QE) monetary policy and lowered interest rates to manage the crises, the Bank of Korea (BOK) pursued interest and financial restructuring as well as banking system digitization to overcome the crises. Covid-19 has disrupted the normal operation of banks, and the central banks and governments of both countries have implemented a variety of monetary and other measures to mitigate its economic and financial consequences. This study aims to identify and assess the health of domestic banks in Japan and South Korea for the Covid-19 ex-ante and interim periods. Several important variables, i.e., portfolios of assets and liabilities, asset productivity, stockholders' equity, profitability, and operating efficiency, have been included to evaluate the health of their banks. This compari-son of health metrics for 2010 to 2020 could help identify changes or shifts in the banking sector of Japan and Korea. The study has used ex-ploratory and descriptive methodologies to undertake qualitative and quantitative evaluations of important bank health indicators in the ex-ante and interim periods of Covid-19. It also used a hybrid method to produce research goals and arguments, including a framework based on what was already known in the field
