Can regulators allow banks to set their own capital ratios?

Basel regulators have received widespread criticism for failing to prevent two credit crises that hit the U.S. over the last two decades. Nonetheless, banks were considerably overcapitalized prior to the onset of the 2007–2009 subprime crisis compared to those which had undergone the 1990–1991 recession. Therefore, if capital requirements were achieved prior to the subprime crisis, how could the Basel framework be blamed again for having accelerated if not caused another credit crunch? We find that the answer to this question lies in the relationship between the capital ratio and the leverage ratio which is governed by risk-weights categories determined by the Basel regulation. We show that changes to risk-weight categories which affect the correlation pattern between both ratios are not reflected in the subprime crisis. This minimizes the implication of the Basel II regulation in the crunch that succeeded its announcement, in contrast to Basel I. We demonstrate that these dynamics are governed by a formula linking the two ratios together which derives from the sensitivity of the risk-based capital ratio to a change in its risk-weight(s). One implication of our work regarding the Basel III regulation consists in validating the newly established capital increments in a mathematical rather than heuristical approach.     

Political connection and leverage: Some Malaysian evidence

This paper extends prior work on the linkage between politically connected (PCON) firms and capital structure in developing countries. Specifically, this paper focuses on the association between Malaysian PCON firms and leverage, and is motivated by the results of Fraser et al. (2006) who report a positive association between leverage and political patronage. Controlling for a potential misspecification in that paper, this study documents that a significant proportion (almost 12%) of the Malaysian PCON firms have negative equity, and builds on the previous paper by providing fresh evidence that market to book ratio is positively associated with leverage, and that borrowing PCON firms have significantly lower ROA compared to non-PCON firms.     

Incentives and financial crises: Microfounded macroprudential regulation

We provide a micro-based rationale for macroprudential capital regulation of financial intermediaries (banks) by developing a model in which bankers can privately undertake a costly effort and reduce the probability of adverse shocks to their asset holdings that force liquidation (deterioration risk). A decline in the fundamental risk of assets ameliorates funding conditions, boosting the banks’ ability to expand their balance sheets. In principle, a higher continuation value would improve incentives to put effort. However, the rise in asset demand and prices also increases the payoff in liquidation, eventually reducing the equilibrium optimal effort. Poor incentives impose socially inefficient liquidation and can be corrected through a regulatory capital requirement. We show that the requirement should be high when fundamental risk is low. Therefore, the model suggests a theoretical foundation for macroprudential regulation and the countercyclical capital buffer of Basel III.     

巴塞尔协议的演变历程梳理

巴塞尔协议在金融国际化和全球化程度不断加深的大背景之下成立并随着经济形势的变化而不断演进。巴塞尔协议经历了三个历史阶段,每一次巴塞尔协议的演进都是对前一次的补充和修订,最低资本要求是三代巴塞尔协议的核心内容之一。本文旨在对巴塞尔协议的相关文件进行逻辑梳理,为其演变历程找出清晰的脉络。     

从固定资产重估看银行资本的提升

分析在国内外会计准则下,通过固定资产重估提升银行资本、缓解监管压力的可行性。根据我国会计准则的相关要求,在固定资产重估方面,目前只能通过投资性房地产重估、固定资产转换与并购重组三种路径提升银行资本,从而达到提升资本充足率的目的,但前两种方法却在一定程度上降低了杠杆率水平,且其市场实施效果也并不乐观。     

On the relation between the market-to-book ratio, growth opportunity, and leverage ratio

The negative relation between the market-to-book ratio and leverage ratio is one of the most widely documented empirical regularities in the capital structure literature. Most related studies take this negative relation as given and debate about its economic interpretation. We show that firms with higher market-to-book ratios face lower debt financing costs and borrow more. The relation between the market-to-book ratio and leverage ratio is not monotonic and is positive for most firms (more than 88% of COMPUSTAT firms and more than 95% of total market capitalization). The previously documented negative relation is driven by a subset of firms with high market-to-book ratios.     

Do the business cycle and revenue diversification matter for banks’ capital buffer and credit risk: Evidence from ASEAN banks

We examine the association of the business cycle and revenue diversification with the banks’ capital buffer and credit risk for a sample of banks from the Association of Southeast Asian Nations (ASEAN) region from 1998 to 2018, using 2847 banking firm–year observations. We find that ASEAN region banks react anticyclically in adjusting their capital buffer levels and credit risk. We find revenue diversification benefits and that banks, through revenue diversification, can reduce their credit risk while achieving capital savings when confronting economic downturns. Our results offer support for the Basel III accord. However, the relations revealed are somewhat moderated by the regulatory quality, competition, and phase of the business cycle encountered by ASEAN region banks.

The Impact of Owner’s Identity on Banks’ Capital Adequacy and Liquidity Risk

In this article, we test the potential impact of the owner’s identity on banks’ capital adequacy and liquidity risk as defined by the Basel III regulatory framework. Using a unique dataset on a sample of banks domiciled in the Middle East and North Africa region, we find that the ownership structure is an important driver of banks’ regulatory capital and liquidity risk. Private and foreign investors exhibit a stronger preference for higher levels of capital, whereas the impact of government ownership on banks’ risk remains inconclusive. Moreover, privately-owned banks evidenced lower levels of liquidity risk compared to the other groups during the last financial crisis because of tighter budget constraints and more compelling liquidity needs.     

Competitive effects of Basel II on US bank credit card lending

We analyze the potential competitive effects of the proposed Basel II capital regulations on US bank credit card lending. We find that bank issuers operating under Basel II will face higher regulatory capital minimums than Basel I banks, with differences due to the way the two regulations treat reserves and gain-on-sale of securitized assets. During periods of normal economic conditions, this is not likely to have a competitive effect; however, during periods of substantial stress in credit card portfolios, Basel II banks could face a significant competitive disadvantage relative to Basel I banks and nonbank issuers.     

Financial Innovation,Basel Accord III,and Bank Value

I examine how financial innovation and Basel III capital requirements in Taiwan respond differently to banking crises and market competition. My panel data set comprises data from thirty-four banks for 2000-2012. I find a significant negative relationship between derivatives and the value of a bank and significant positive relationships among the capital adequacy ratio, bank-specific variables, and the value of a bank. Larger bank size and operational diversification tend to be positively associated with a bank's value, the holding of a relatively high amount of capital requirements, and nonperforming loans that are large. The latter result may simply reflect the scale of economy and improvement of efficiency in terms of financial innovation in the banking sector.

股票流动性对公司资本结构的影响研究

本文分析了流动性对公司资本结构的影响。理论分析表明,一个公司股权交易流动性的提高,使得公司股权融资成本得以降低,公司更倾向于采用增发、配股等股权融资的方式融资,这会降低公司的财务杠杆率。同时,借鉴资本结构动态调整的思想分析,发现个股流动性越高,资本结构的调整速度越快。本文基于2002—2010沪深两市发行的非金融业A股数据,采用面板数据回归等方法研究了股票流动性等因素对公司资本结构的影响,本文的经验结果支持这一理论假设。
