Bank Capital: Lessons from the Financial Crisis

Using a multicountry panel of banks, we study whether better capitalized banks experienced higher stock returns during the financial crisis. We differentiate among various types of capital ratios: the Basel risk‐adjusted ratio, the leverage ratio, the Tier 1 and Tier 2 ratios, and the tangible equity ratio. We find several results: (i) before the crisis, differences in capital did not have much impact on stock returns; (ii) during the crisis, a stronger capital position was associated with better stock market performance, most markedly for larger banks; (iii) the relationship between stock returns and capital is stronger when capital is measured by the leverage ratio rather than the risk‐adjusted capital ratio; (iv) higher quality forms of capital, such as Tier 1 capital and tangible common equity, were more relevant.     

Government finances and bank bailouts: Evidence from European stock markets

Using a sample of European banks and a series of events affecting governments' finances, we conduct an event study to examine whether there is a relationship between governments' fiscal difficulties and banks' stock returns. We find a significant reaction of banks' stocks to news concerning governments' finances. Banks' stock returns fall in response to a deterioration of governments' financial situation. We find little difference in the reaction between large and small banks. The evidence points towards all banks being equally likely to be bailed out. Our data are consistent with a policy during the Eurozone sovereign-debt crisis in which “no bank is too small to save”.     

Bank Liquidity Creation and Risk‐Taking: Does Managerial Ability Matter?

This study investigates the impact of managerial ability on banks' liquidity creation and risk‐taking behavior. We find that higher ability managers create more liquidity and take more risk. During times of financial crisis, however, higher ability bank managers reduce liquidity creation as a way to de‐leverage their balance sheets. Our findings inform recent theoretical and empirical studies that investigate determinants of liquidity creation and risk by introducing managerial ability as a prominent antecedent of the banks' intermediation and risk‐transforming service. Moreover, this study has policy‐related implications, since managerial ability can be quantified as a key performance indicator for prudential supervision of banks and could help regulators to target intervention efforts more purposefully during times of crisis.     

How Banks' Value-at-Risk Disclosures Predict their Total and Priced Risk: Effects of Bank Technical Sophistication and Learning over Time

Using a sample of eight large commercial banks from 1994 to 2000, Jorion (2002) finds that banks' VaR disclosures for their trading portfolios predict trading income variability. We extend Jorion's findings using a larger sample of 17 banks from 1997 to 2002 reporting trading VaRs under FRR No. 48 (1997). We find that banks' trading VaRs have predictive power for trading income variability that increases with bank technical sophistication and over time. We find that banks' trading VaRs have predictive power for a bank-wide measure of total risk, return variability, and for two bank-wide measures of priced risk, beta and realized returns.     

The credit crisis around the globe: Why did some banks perform better?

Though overall bank performance from July 2007 to December 2008 was the worst since the Great Depression, there is significant variation in the cross-section of stock returns of large banks across the world during that period. We use this variation to evaluate the importance of factors that have been put forth as having contributed to the poor performance of banks during the credit crisis. The evidence is supportive of theories that emphasize the fragility of banks financed with short-term capital market funding. The better-performing banks had less leverage and lower returns immediately before the crisis. Differences in banking regulations across countries are generally uncorrelated with the performance of banks during the crisis, except that large banks from countries with more restrictions on bank activities performed better and decreased loans less. Our evidence poses a substantial challenge to those who argue that poor bank governance was a major cause of the crisis because we find that banks with more shareholder-friendly boards performed significantly worse during the crisis than other banks, were not less risky before the crisis, and reduced loans more during the crisis.     

Estimating risk efficiency in Middle East banks before and after the crisis: A metafrontier framework

The aim of this study is three-fold. Firstly, it attempts to analyse the effect of risk on Middle East banks' efficiency levels before and after the recent financial crisis. Secondly, it seeks to determine the influence of bank size taking into consideration the possible inefficiency originated to risk abatement cost. Thirdly, it investigates the possible effect of oil price shocks on banks' performance. To examine these issues we introduce a risk efficiency index based on an output orientated directional distance function with weak and strong disposability assumptions. The methodology has been applied on a panel of Middle East banks spanning the period 1998–2014.The empirical findings suggest that on average small banks are more efficient and their size has less negative impact on their technical efficiency and risk management. On the other hand, large banks' risk management is found to be more flexible during the financial crisis. Moreover, banks with higher fixed assets are associated with more costly disposals of non-performing loans justifying the rejection of a positive relation between bank size and technical efficiency. Finally, oil price shocks play a significant role.     

International compliance with new Basel Accord principles for risk governance

We assess international compliance with the Basel Committee's 2010 guidance on governance of banking organisations. Based on an extensive examination of regulatory documents in selected advanced economies, we find that reform is incomplete in jurisdictions most affected by the financial crisis, and with the largest financial centres. In contrast, other countries less affected by the financial crisis have enacted risk governance reforms as protection against potential future contagion. We provide insights for policy‐makers charged with improving governance at banks, and a richer understanding for international regulators as they revise the guidelines and aim for greater compliance at the national level.     

On the Role of Regulatory Banking Capital

In this paper the authors study the role of regulatory banking capital and analyze the incentive effects of the Basel II Accord. They argue that Basel II may become a source of systemic risk due to endogenous risk and the risk sensitivity of the capital requirements. In this context they note that financial instability may enter via the asset side of the banks' balance sheets when banks are forced to sell assets in order to maintain the capital buffer prescribed by Basel II.     

Loan loss provisions and return predictability: A dynamic perspective

This paper examines the impact of loan loss provisions (LLPs) on return predictability during 1994–2017. We find that on average, LLPs are negatively associated with one year ahead stock returns. This effect is particularly significant during the global financial crisis but much weaker during the Basel II and III periods. Consistent with these findings, a long–short trading strategy based on LLPs generates positive abnormal returns during the Basel II and III periods but negative abnormal returns during the financial crisis. Cross-sectional tests show that this effect is more pronounced among banks with greater information asymmetry. Decomposition of LLPs suggests that these findings are driven mainly by nondiscretionary LLPs. Overall, our results suggest that the relationship between LLPs and future stock returns is not linear but contingent on bank regulations and macroeconomic conditions.     

Banks and Corporate Decisions: Evidence from Business Groups

Banks who can influence clients' governance may steer those clients into mergers to reduce the banks' own risk. Empirical evidence based on Japan's mergers and acquisitions (M&As) during the country's 1990s banking crisis indicates that acquirers with stronger bank ties made acquisitions that they would not have normally made. These acquirers lost more shareholder value via mergers than acquirers with weaker bank ties. The banks' risk was reduced, while the banks' shareholders gained significant excess returns from their borrowers' mergers. This paper offers implications for corporate governance of firms with strong bank ties and advances the existing knowledge on business groups.     

The interest rate pass-through in the euro area during the sovereign debt crisis

We investigate the pass-through of monetary policy to bank lending rates in the euro area during the sovereign debt crisis, in comparison to the pre-crisis period. We make the following contributions. First, we use a factor-augmented vector autoregression, which allows us to assess the responses of a large number of country-specific interest rates and spreads. Second, we analyze the effects of monetary policy on the components of the interest rate pass-through, which reflect banks' funding risk (including sovereign risk) and markups charged by banks over funding costs. Third, we not only consider conventional but also unconventional monetary policy. We find that while the transmission of conventional monetary policy to bank lending rates has not changed with the crisis, the composition of the pass-through has changed. Specifically, expansionary conventional monetary policy lowered sovereign risk in peripheral countries and longer-term bank funding risk in peripheral and core countries during the crisis, but has been unable to lower banks' markups. This was not, or not as much, the case prior to the crisis. Unconventional monetary policy helped decreasing lending rates, mainly due to large shocks rather than a strong propagation.     

Short-term wholesale funding and systemic risk: A global CoVaR approach

We use the CoVaR approach to identify the main factors behind systemic risk in a set of large international banks. We find that short-term wholesale funding is a key determinant in triggering systemic risk episodes. In contrast, we find weaker evidence that either size or leverage contributes to systemic risk within the class of large international banks. We also show that asymmetries based on the sign of bank returns play an important role in capturing the sensitivity of system-wide risk to individual bank returns. Since short-term wholesale funding emerges as the most relevant systemic factor, our results support the Basel Committee’s proposal to introduce a net stable funding ratio, penalizing excessive exposure to liquidity risk.     

中国商业银行脆弱性的诱发因素及监管——基于资产减值和杠杆率视角

选取2008年前上市的16家银行2008-2018年的财务数据,对商业银行脆弱性进行分析。研究发现：商业银行脆弱性虽然是多方面因素共同作用的结果,但其对杠杆率变动尤其敏感;国有商业银行对商业银行总体脆弱性贡献占比较大;股份制商业银行更易受到资产减值风险的冲击。政策模拟结果显示,增加四家系统重要性银行的权益资本并对其进行严格的杠杆率监管是降低商业银行总体脆弱性较为有效的途径。     

This Time Is the Same: Using Bank Performance in 1998 to Explain Bank Performance during the Recent Financial Crisis

Are some banks prone to perform poorly during crises? If yes, why? In this paper, we show that a bank's stock return performance during the 1998 crisis predicts its stock return performance and probability of failure during the recent financial crisis. This effect is economically large. Our findings are consistent with persistence in a bank's risk culture and/or aspects of its business model that make its performance sensitive to crises. Banks that relied more on short‐term funding, had more leverage, and grew more are more likely to be banks that performed poorly in both crises.     

Ambiguity and risk factors in bank stocks

The determinants of banks' cost of equity are not well understood. We depart from prior work assuming rational expectations and instead explore the impact of Knightian uncertainty or ambiguity on bank stocks. We test a large set of asset pricing models and find that investors' lack of confidence in both the drift and correlation structure driving bank stock returns affects banks' cost of capital. We also investigate the economic relation among ambiguity, market liquidity, and banks' capital shortfall, which reveals the transmission channels through which ambiguity may increase the probability of a systemic crisis. Our findings have implications for macroprudential policy.     

Banks’ capital buffer,risk and performance in the Canadian banking system: Impact of business cycles and regulatory changes

Using quarterly financial statements and stock market data from 1982 to 2010 for the six largest Canadian chartered banks, this paper documents positive co-movement between Canadian banks’ capital buffer and business cycles. The adoption of Basel Accords and the balance sheet leverage cap imposed by Canadian banking regulations did not change this cyclical behavior of Canadian bank capital. We find Canadian banks to be well-capitalized and that they hold a larger capital buffer in expansion than in recession, which may explain how they weathered the recent subprime financial crisis so well. This evidence that Canadian banks ride the business and regulatory periods underscores the appropriateness of a both micro- and a macro-prudential “through-the-cycle” approach to capital adequacy as advocated in the proposed Basel III framework to strengthen the resilience of the banking sector.     

Banks’ equity performance and the term structure of interest rates

Using an extensive global sample, this paper investigates the impact of the term structure of interest rates on bank equity returns. Decomposing the yield curve to its three constituents (level, slope and curvature), the paper evaluates the time‐varying sensitivity of the bank's equity returns to these constituents by using a diagonal dynamic conditional correlation multivariate GARCH framework. Evidence reveals that the empirical proxies for the three factors explain the variations in equity returns above and beyond the market‐wide effect. More specifically, shocks to the long‐term (level) and short‐term (slope) factors have a statistically significant impact on equity returns, while those on the medium‐term (curvature) factor are less clear‐cut. Bank size plays an important role in the sense that exposures are higher for SIFIs and large banks compared to medium and small banks. Moreover, banks exhibit greater sensitivities to all risk factors during the crisis and post‐crisis periods compared to the pre‐crisis period; though these sensitivities do not differ for market‐oriented and bank‐oriented financial systems.     

Did Good Corporate Governance Improve Bank Performance during the Financial Crisis?

This paper focuses on the effects of corporate governance on bank performance during the financial crisis of 2008. Using data on large publicly traded U.S. banks, we examine whether banks with stronger corporate governance mechanisms were associated with higher profitability and better stock market performance amidst the crisis. Our empirical findings on the effects of corporate governance on bank performance are mixed. Although the results suggest that banks with stronger corporate governance mechanisms were associated with higher profitability in 2008, our findings also indicate that strong governance may have had negative effects on stock market valuations of banks amidst the crisis. Nevertheless, we document that banks with strong corporate governance practices had substantially higher stock returns in the aftermath of the market meltdown, indicating that good governance may have mitigated the adverse influence of the crisis on bank credibility.     

A model of liquidity hoarding and term premia in inter-bank markets

Financial crises are associated with reduced volumes and extreme levels of rates for term inter-bank loans, reflected in one-month and three-month LIBOR. We explain such stress by modeling leveraged banks' precautionary demand for liquidity. Asset shocks impair a bank's ability to roll over debt because of agency problems associated with high leverage. In turn, banks hoard liquidity and decrease term lending as their rollover risk increases over the term of the loan. High levels of short-term leverage and illiquidity of assets lead to low volumes and high rates for term borrowing. In extremis, inter-bank markets can completely freeze.     

IS THE BOOK‐TO‐MARKET RATIO A MEASURE OF RISK?

We develop a leverage‐based alternative to traditional asset pricing models to investigate whether the book‐to‐market ratio acts as a proxy for risk. We argue that the book‐to‐market ratio should act as a proxy because of the expected relations between (1) financial risk and measures of capital structure based on the market value of equity and (2) asset risk and measures of capital structure based on the book value of equity. We find no relation between average stock returns and the book‐to‐market ratio in all‐equity firms after controlling for firm size, and an inverse relation between average stock returns and the book‐to‐market ratio in firms with a negative book value of equity.
