The Eurozone banking sector in the time of COVID-19: Measuring volatility connectedness

This article investigates the volatility connectedness of the Eurozone banking system over the last 15 years (from 2005 to 2020). Applying the Diebold-Yilmaz Connectedness Index model to the daily stock return volatilities of 30 major Eurozone banks, we are able to measure the risk spillover effects and to capture the COVID-19 outbreak's impact on banking stability. The empirical findings show that the 30 banks are highly interconnected. Furthermore, we show the strong impact of the COVID-19 pandemic on the volatility dynamics, i.e., on the structure of the Eurozone banking system. Dynamically, we find that volatility connectedness increases during crises, reaching its maximum peak at the time of COVID-19. The analysis points out the critical role of volatility transmission played by large banks, highlighting the “too-big-to-fail” characteristic of this banking system. However, we find that small-medium banks are important actors of contagion, supporting the thesis that the Eurozone banking system is also “too-interconnected to fail.” Finally, we document the heterogeneity effect of the COVID-19 pandemic between Eurozone banking systems. This heterogeneity impact could be a future source of financial instability within the Eurozone.     

金融政策竞争中性与民营企业融资纾困——来自突发公共卫生事件的准自然实验

本文以新冠肺炎疫情这一突发公共卫生事件为准自然实验,选择疫情前后我国债券市场数据,研究金融政策竞争中性原则实现情况及其途径。研究发现,相比国有企业,民营企业融资成本在疫情期间明显降低,金融政策的竞争中性得到进一步体现;那些为供应链上下游提供商业信用支持的民营企业,其融资成本降低幅度更大。同时,疫情期间一些应急性融资工具也向民营企业倾斜,更有利于降低民营企业的融资成本。进一步检验发现,供应链上下游受影响程度越严重、为上下游提供的商业信用期限越长,民营企业的融资成本降低幅度越大;疫情期间的金融政策并没有导致民营企业出现“脱实向虚”现象,反而降低了其金融化水平、提升了资金使用效率。研究结果显示,对民营企业不愿贷、不敢贷的现象并不等于金融政策存在非竞争中性,而是源于金融机构在执行层面的顾虑,我国应对突发公共卫生事件推出的金融政策有效缓解了信贷市场执行层面的这一顾虑。本文研究结论从金融政策竞争中性出发,为给民营企业营造公平竞争环境提供了有益启示。     

The International Bank Lending Channel of Monetary Policy Rates and QE: Credit Supply,Reach‐for‐Yield,and Real Effects

We identify the international credit channel by exploiting Mexican supervisory data sets and foreign monetary policy shocks in a country with a large presence of European and U.S. banks. A softening of foreign monetary policy expands credit supply of foreign banks (e.g., U.K. policy affects credit supply in Mexico via U.K. banks), inducing strong firm‐level real effects. Results support an international risk‐taking channel and spillovers of core countries’ monetary policies to emerging markets, both in the foreign monetary softening part (with higher credit and liquidity risk‐taking by foreign banks) and in the tightening part (with negative local firm‐level real effects).     

Does economic policy uncertainty drive the dynamic spillover among traditional currencies and cryptocurrencies? The role of the COVID-19 pandemic

The paper examines the dynamic spillover among traditional currencies and cryptocurrencies before and during the COVID-19 pandemic and investigates whether economic policy uncertainty (EPU) impacts this spillover. Based on the TVP-VAR approach, we find evidence of spillover effects among currencies, which increased widely during the pandemic. In addition, results suggest that almost all cryptocurrencies remain as “safe-haven” tools against market uncertainty during the COVID-19 period. Moreover, comparative analysis shows that the total connectedness for cryptocurrencies is lower than for traditional currencies during the crisis. Further analysis using quantile regression suggests that EPU exerts an impact on the total and the net spillovers with different degrees across currencies and this impact is affected by the health crisis. Our findings have important policy implications for policymakers, investors, and international traders.     

Banking sector reactions to COVID-19: The role of bank-specific factors and government policy responses

This paper examines the impact of bank-specific factors and variations in the context of stringency of government policy responses on bank stock returns because of the COVID-19 pandemic. A sample of 1,927 publicly listed banks from 110 countries is used for the period of the first major wave of COVID-19, that is, January to May 2020. Our findings indicate that stock returns of banks with higher capitalization and deposits, more diversification, lower non-performing loans, and larger size are more resilient to the pandemic. While banks’ environment and governance scores do not have a significant impact, higher social and corporate social responsibility strategy scores intensify the negative stock price reaction to COVID-19. We further observe that the pandemic-induced reduction in bank stock prices is mitigated as the strictness of government policy responses increases, mainly through economic responses such as income support, debt and contract relief, and fiscal measures from governments.     

Exploring the relationship between cryptocurrencies and hedge funds during COVID-19 crisis

In this paper, we investigated the relationship between cryptocurrency market and hedge funds in two different ways. First, we focus on the dependence between Cryptocurrency hedge funds and conventional hedge funds strategies using VAR and VECM models, while analyzing the impact of COVID-19 on the hedge funds' values. Secondly, we choose between ARDL and ARDL-ECM models to study the effects of cryptocurrency price changes on Crypto- Currency hedge funds' values during COVID-19 crisis. Our empirical findings demonstrate that there is substantial interactions between Crypto-Currency and conventional hedge funds. The COVID-19 pandemic has significant negative impact on the performance of the following hedge funds: Event Driven, Relative Value and Distressed Debt fund strategies, this has reflected in a significant drop in their values during this critical period. However, we demonstrate that COVID-19 pandemic did not affect the relationship between crypto-currency hedge funds and both bitcoin and Ethereum. These findings hold profound implications for hedge funds managers, cryptocurrency market main players and policy makers. Our study is crucial in forecasting the performance of these markets especially during global pandemics.     

When bitcoin lost its position: Cryptocurrency uncertainty and the dynamic spillover among cryptocurrencies before and during the COVID-19 pandemic

This paper examines the dynamic spillovers among the major cryptocurrencies under different market conditions and accounts for the ongoing COVID-19 health crisis. We also investigate whether cryptocurrency policy (CCPO) uncertainty and cryptocurrency price (CCPR) uncertainty affect the dynamic connectedness. We adopt the Quantile-VAR approach to capture the left and right tails of the distributions corresponding to return spillovers under different market conditions. Generally, cryptocurrencies show heterogeneous responses to the occurrence of the COVID-19 pandemic. We find that the total spillover index (TCI) varies across quantiles and rises widely during extreme market conditions, with a noticeable impact of the COVID-19 pandemic. Bitcoin lost its position as a dominant “hedger” during the health crisis, while Litecoin became the most dominant “hedger” and/or “safe-haven” asset before and during the pandemic period. Moreover, our analysis shows a significant impact of market uncertainties on total and net connectedness among the five cryptocurrencies. We argue that the COVID-19 pandemic crisis plays a vital role on the relationship between CCPO as well as CCPR and the dynamic connectedness across all market conditions.     

Covid-19 pandemic,a catalyst for aggressive earnings management by banks?

This paper investigates the effects of the Covid-19 pandemic on the financial reporting quality of European banks by examining the occurrence of earnings management specifically income smoothing. Using a sample of listed European banks, we employ panel estimation to compare income smoothing in the pre-pandemic period (2019Q1-2019Q4) and the pandemic period (2020Q1-2021Q4). We find that earnings management has significantly increased during the pandemic years, evidencing how the quality of financial reporting is affected during the crisis period. Our findings further suggest that amid the crisis, governance quality limits the incidence of earnings management and emphasizes how the strength of country-level governance and institutional framework affects the quality of financial reporting. Further analysis shows that though banks are inclined to manage earnings during a crisis, nevertheless, the presence of high-quality audit is a limiting factor on the incidence of earnings management in the face of crisis. Our findings which are relevant to investors, market participants, and regulators among others make a significant contribution to the accounting literature and specifically complement the strand of literature on the discretionary use of loan loss provision for earnings management during crisis.     

Role of bank credit on local growth: Do politics and crisis matter?

Although state-owned banks are expected to promote the growth of less-developed regions, especially in developing economies, several cross-country studies report that lending by state banks is associated with the inefficient allocation of credit and low levels of development. Further, state banks have been found to lend to their cronies, especially around elections. In this paper, we study the lending activities of state-owned and private banks during the period 1992–2010 and analyze the relationship between the credit these banks provide and local economic growth in Turkey during crisis periods and in election years. We find that the share of state-owned banks in the credit market in crisis periods and local election years is significantly higher than their share in non-crisis and non-election periods. The per capita real credit that state-owned banks provide during crisis years is found to be positively associated with local growth in all provinces. Our results suggest that although state-owned banks might issue loans for political reasons in election periods, they also seem to play an important role in offsetting the adverse effects of economic shocks, especially in developed provinces.     

The Effect of Firms' Information Exposure on Safeguarding Employee Health: Evidence from COVID-19

We show that information exposure through international business networks enables firms to take proactive measures that benefit employees and potentially the local community. Specifically, in the early days of COVID-19, firms that have business networks with China and Italy are more likely to be aware of the severity of the disease, and proactively implement work-from-home (“WFH”) policies that can protect their employees. Using Safegraph foot traffic data, we find a higher stay-at-home ratio before local governments impose lockdowns in zip codes where firms have a larger information exposure. These areas are also associated with a lower spread of COVID-19. Our main findings are more pronounced when local governments face constraints in quickly responding to COVID-19 and when firms have a higher WFH capability or have more investors with socially responsible preferences. Collectively, we present evidence on the role of private corporations in mitigating the negative effects of a public health crisis before government intervention.     

Zombie companies in China in the COVID-19 era

COVID-19 poses novel sources of uncertainty and risk to companies, but it also offers many opportunities. In the COVID-19 era, unprecedented government and central bank interventions to tackle the economic crisis precipitated by the pandemic have reinvigorated the debate on the threat of a zombification of the economy in China, caused by unviable companies being kept alive artificially. This particular consequence of COVID-19 may aggravate the economic problem of zombie companies in China, increase the risk of further zombification, and create new zombie companies. Recognizing the risk factors of zombie companies and revisiting corporate insolvency law in China, this article aims to address a gap in knowledge related to how zombie companies are being handled in practice in China in the era of the pandemic. In particular, we will investigate the definition, recognition, and uniqueness of zombie companies in the context of COVID-19, and propose several policy actions, primarily through Chinese insolvency law, to mitigate the risk of the return of zombie companies or a further zombification of the economy. It is anticipated that these measures will help to enhance China's sustainable economic recovery in the wake of the COVID-19 pandemic.     

Risk contagion of COVID-19 in Japanese firms: A network approach

The novel coronavirus disease (COVID-19) is one of the worst pandemics in human history. Our research objective is to assess the contagion effect on Japanese firms and to evaluate the Japanese government's COVID-19 measures during the period from April 7, 2020, to May 25, 2020. We propose a susceptible-infected-recovered-dead model for COVID-19 and derive COVID-19 parameters for Japan. Subsequently, we analyze the effect of COVID-19 on Japanese firms through correlation-based network and credit risk analyses. The main findings are that the Tokyo Stock Price Index moved in the opposite direction of COVID-19 parameters and COVID-19 parameters are almost the only risk factors that impact a firm's credit risk during the period. Finally, we find that the interconnection analysis between the COVID-19 infection network and the financial networks contribute to the existing pandemic risk management knowledge.     

Government interventions and default risk: Does one size fit all?

We examine the effectiveness of the financial sector rescue packages provided by the national governments during the 2008 financial crisis. This study questions the implicit assumption that government interventions have an uniform effect on the default risk of individual banks. After testing the results for sensitivity, our main findings suggest that there exists a significant negative relationship between the announcement of the financial sector rescue packages and the daily change of the credit default premium. However, quantile regressions show that the effectiveness of these packages differs across banks: most interventions do not decrease the risk of intermediate to low-risk banks, while they do reduce the risk of high-risk banks. Besides, we find that interventions aimed at specific financial institutions are more effective in restraining banking risk than broad interventions taken to stabilize the financial market as a whole.     

Investor information and bank instability during the European debt crisis

Outside of financial crises, investors have little incentive to produce private information on banks’ short-term liabilities held as information-insensitive safe assets. The same does not hold during crises. We compare the information effects of different policy interventions. We measure information production using credit default swap spreads during the Global Financial Crisis and the European debt crisis. We study abnormal information production around major events and find that capital injections reduced abnormal information production while early European stress tests increased it. High levels of information production predict bank balance sheet contraction and higher government expenditures to support financial institutions.     

绿色信贷政策得不偿失还是得偿所愿？——基于资源配置视角的PSM-DID成本效率分析

党的十九大报告聚焦生态文明体制改革,明确提出了发展绿色金融的战略要求。商业银行作为实施绿色信贷政策的主体,更加关注因此而产生的成本效率问题,即考量银行自身是得不偿失抑或得偿所愿？本文基于2005—2017年间73家中国商业银行的数据,首先,运用SFA模型测算商业银行的成本效率;其次,运用倾向得分匹配—双重差分法(PSM-DID)实证分析绿色信贷政策对银行成本效率影响的净效应;最后,采用边际动态检验方法考察绿色信贷政策净效应的影响趋势。文章发现绿色信贷政策的实施会通过成本效应机制降低银行成本效率,但同时因其改善了银行的信贷风险管理、提升了银行的声誉,从而对银行成本效率施加正向影响。此外,文章还发现绿色信贷政策的净效应呈现U型趋势,表现为2007—2013年绿色信贷政策净效应负向影响加深,2014年后出现转好信号,现已越过U型谷底。因此,从长期看,绿色信贷政策将有利于银行成本效率提升。     

A shot in the arm: Economic support packages and firm performance during COVID-19

We use firm-level data to provide some early evidence on the effectiveness of COVID-19 economic policy packages. Our empirical strategy relies on the varying degree of vulnerability to the pandemic across industries. We find a robust association of fiscal support with changes in firm performance indicators (as measured by sales-to-assets ratio, profit margin, interest coverage ratio as well as probability of default) in pandemic-prone sectors. We also observe marginal effects of monetary policy on the sales-to-assets ratio and of foreign exchange intervention on the interest coverage ratio in the hardest-hit firms. These results broadly survive a battery of exercises to address endogeneity. Additionally, we show that firms with a better financial position are more likely to take advantage of the support packages to withstand the pandemic shock. Overall, this preliminary evidence suggests that policy interventions have bought time for the hardest-hit industries, by supporting turnover and improving liquidity.     

COVID-19 as a stress test: Assessing the bank regulatory framework

The broad economic damage of the COVID-19 pandemic poses the first major test of the bank regulatory reforms put in place after the Global Financial Crisis. Our study assesses the U.S. regulatory framework, with an emphasis on capital and liquidity requirements. Prior to the COVID-19 crisis, banks were well capitalized and held ample liquid assets, which partly reflects enhanced requirements. The overall robust capital and liquidity levels resulted in a resilient banking system, which maintained lending and market making through the early stages of the pandemic. Trading activity was a source of strength for banks, reflecting in part a prudent regulatory approach. That said, leverage requirements are associated with more repo position netting by banks, with potential implications for market making.     

On the role of Islamic and conventional banks in the monetary policy transmission in Malaysia: Do size and liquidity matter?

This paper empirically investigates the impact of monetary policy on the credit supply of Islamic versus conventional banks of Malaysia using an unbalanced panel dataset over the period 2005-2016. While estimating the effects of three alternative measures of monetary policy on banks' credit supply, we include several bank-specific and macroeconomic variables in the specification as control variables. We provide strong evidence on the existence of the credit channel of monetary policy transmission mechanism in Malaysia. Yet, we show that Islamic banks respond considerably less to changes in monetary policy instruments as compared to their conventional counterparts. We also find that the monetary policy measures affect small-sized banks and less-liquid banks more as compared to large-sized and more-liquid banks. Our findings suggest that for an effective monetary policy, there is a vital need to consider the nature of Islamic banking while devising any monetary policy instruments to manage credit supply in the economy.     

Does CSR matter in times of crisis? Evidence from the COVID-19 pandemic

The debate over how firm stakeholder engagement is tied to preserving shareholder wealth has received growing attention in recent years, especially in the wake of the COVID-19 crisis. Against this backdrop, we examine the relation between corporate social responsibility (CSR) and stock market returns during the COVID-19 pandemic-induced market crash and the post-crash recovery. Using a sample of 1750 U.S. firms and two major sources of CSR ratings, we find no evidence that CSR affected stock returns during the crash period. This result is robust to various sensitivity tests. In additional cross-sectional analysis, we find some supporting evidence, albeit weak, that the relation between CSR and stock returns during the pandemic-related crisis is more positive when CSR is congruent with a firm's institutional environment. We also find that Business Roundtable companies, which committed to protecting stakeholder interests prior to the pandemic, do not outperform during the pandemic crisis. We conclude that pre-crisis CSR is not effective at shielding shareholder wealth from the adverse effects of a crisis, suggesting a potential disconnect between firms' CSR orientation (ratings) and actual actions. Our evidence suggests that investors can distinguish between genuine CSR and firms engaging in cheap talk.
