Bank Portfolio Allocation: The Impact of Capital Requirements, Regulatory Monitoring, and Economic Conditions

This paper develops a structural, dynamic model of a banking firm to analyze how banks adjust their loan portfolios over time. In the model, banks experience capital shocks, face uncertain future loan demand, and incur costs based on their proximity to regulatory minimum capital requirements and the intensity of regulatory monitoring. Implications of the model then are estimated using panel data on large U.S. commercial banks operating continuously between December 1989 and December 1997. The estimated model is used to simulate the optimal bank response to (1) past and proposed changes in capital requirements, (2) changes in regulatory monitoring intensity, and (3) economic downturns. The simulation results are used to shed light on the decline in loan growth and the rise in bank capital ratios witnessed over a decade ago as well as the possible impact of the current proposed modification to capital requirements.

Potential Competitive Effects of Basel II on Banks in SME Credit Markets in the United States

We examine the likely competitive effects of implementation of Basel II capital requirements on banks in the market for credit to SMEs in the U.S. Similar competitive effects from Basel II may occur for other credits and financial instruments in the U.S. and other nations. We address whether reduced risk weights for SME credits extended by large banking organizations that adopt the Advanced Internal Ratings-Based (A-IRB) approach of Basel II might significantly adversely affect the competitive positions of other organizations. The analyses suggest only relatively minor competitive effects on most community banks because the large A-IRB adopters tend to make very different types of SME loans to different types of borrowers than community banks. However, there may be significant adverse effects on the competitive positions of large non-A-IRB banking organizations because the data do not suggest any strong segmentation in SME credit markets among large organizations.

中国银行业实施逆周期资本缓冲工具研究

基于《各国监管当局实施逆周期资本缓冲指引》,依据中国金融机构信贷和宏观经济数据,采用“信贷余额/GDP”指标,计算需要计提逆周期资本缓冲的时期和数量,检验逆周期资本缓冲工具对中国银行业的有效性。针对模型与中国国情不符问题,宜将信贷/GOP 指标与相关经济指标配合使用,将系统风险变动作为衡量标准,同时注意与宏观政策的配合。     

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。     

Effects of the New Basel Capital Accord on Bank Capital Requirements for SMEs

Using data from three countries (US, Italy and Australia) and surveying related studies from several other countries in Europe, we investigate the effects of the New Basel Capital Accord on bank capital requirements for small and medium sized enterprises (SMEs). We find that, for all the countries, banks will have significant benefits, in terms of lower capital requirements, when considering small and medium sized firms as retail customers. But they will be obliged to use the Advanced IRB approach and to manage them on a pooled basis. For SMEs as corporate, however, capital requirements will be slightly greater than under the existing Basel I Capital Accord. We believe that most eligible banks will use a blended approach (considering some SMEs as retail and some as corporate). Through a breakeven analysis, we find that for all of our countries, banking organizations will be obliged to classify as retail at least 20% of their SME portfolio in order to maintain the current capital requirement (8%).

The role of regulatory capital in international bank mergers and acquisitions

When investigating the role of regulatory capital in bank mergers and acquisitions (M&As) we finds that US targets are better capitalized than their acquirers and non-acquired peers and that US banks maintain higher capital levels than European banks. Thus, US banks strategically raise their capital levels to avoid regulatory scrutiny. Furthermore, more value is created for targets with high excess capital and in M&As involving targets with considerably higher excess-capital ratios than their acquirers. Thus, the excess regulatory capital hypothesis is supported. Finally, market prices reflect the influence that capital has on the probability of the merger's regulatory approval.     

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.     

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.     

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.     

Why is credit-to-GDP a good measure for setting countercyclical capital buffers?

We examine banks’ loan losses in Europe in 1982–2012 using a nonlinear three-factor model that takes into account output growth, real interest rate, and the ratio of private credit to GDP relative to its trend (i.e., “excessive indebtedness”). We find that a drop in output has an intensified impact on loan losses if the private sector is excessively indebted. Because increased bank credit risk should be matched with higher bank capital, the result motivates the Basel III's countercyclical capital buffers as a function of private indebtedness relative to its trend. The result also helps to explain differences in the amount of loan losses in different recessions across time and across countries. The model also indicates that low interest rates during the recent recession have clearly mitigated loan losses.     

Risk–Return Profiles of Islamic Equities and Commodity Portfolios in Different Market Conditions

Motivated by the recent phenomenal growth in Islamic finance and the financialization of commodities, this study makes an initial attempt to investigate the risk–return profiles of optimized portfolios combining (a) Islamic equities with commodities and (b) conventional equities with commodities during the crises and noncrises periods. The findings tend to indicate that Islamic equity–commodity portfolios provide relatively higher diversification benefits than the conventional equity–commodity portfolios during the 1997 Asian Financial Crisis triggered by the financial sector compared to the 2008 global financial crisis triggered by the real housing sector. The findings further suggest that except for a few cases, commodities in general and gold in particular improve diversification benefits.
