中国银行资本监管模式选择研究

有效银行资本监管涉及降低银行倒闭风险所得到的社会收益与抑制金融业发展所产生的社会成本之间的平衡问题,理想的银行资本监管应随着这些成本和收益的变化而调整,设计一种激励相容的银行资本监管制度成为对银行资本监管的现实需要,无论是标准化模式还是内部模型法都是对银行具体风险评价和风险管理方法的约束,整体监管模式建立在预先承诺制的基础之上,注重激励相容、发挥市场约束和银行自身管理的作用,在适用性、稳定性、可操作性等方面都比内部模型法具有优势。     

关于巴塞尔新资本协议中过程监管模式的研究文献综述

巴塞尔新资本协议的实施正在深刻地重塑全国银行业的风险管理理念和市场格局,它将监督检查列为三大支柱之一,积极促进监管当局实现从规则监管模式向过程监管模式的转变.本文对当前国内外关于过程监管模式的研究文献进行整理,以求对过程监管模式有一个全面深入的综述,为进一步的研究奠定基础.     

银行资本监管与商业银行风险——对中国13家商业银行的实证研究

通过构建模型对2000～2005年我国商业银行风险与资本充足率变化进行实证检验，结果表明，我国实施银行资本监管能够促使已达到最低监管要求的银行提高资本充足率和降低银行风险，但对于达不到监管要求的银行，实施银行资本监管并不能促使其提高资本充足率和降低风险水平。实施银行资本监管不是我国商业银行风险降低的原因，资本监管在市场化程度较高的银行中会失效。市场及投资者并不因为银行资本充足率变化而对上市银行的收益或价值的评价产生变化。改革我国商业银行产权制度、建立显性的存款保险制度、加强市场约束是我国商业银行降低风险、提高资本监管有效性的基础。     

我国银行监管的制度变迁研究

控制性银行监管制度是我国经济快速增长和转型的伴生物,但是,它侵蚀了银行业自身的稳定和效率。目前,银行监管能否顺利实现从控制性监管制度向审慎监管制度的变迁已成为维护金融稳定和公众利益、提高监管有效性的关键环节。本文结合我国国情,从政府利益的角度,探讨了改革开放以来我国银行监管制度变迁的历史逻辑、动态趋向以及构建和强化审慎银行监管制度的制约因素和推动因素。

Bank Capital Adequacy versus Deposit Insurance

This paper re-evaluates the Diamond-Dybvig analysis of deposit insurance by constructing a model in which an agent not in need of liquidity sets up a financial intermediary to sell liquidity insurance to other agents who desire such insurance. This intermediary resembles a real-world bank in that it is financed by both demand deposits and equity. It also dominates the Diamond-Dybvig intermediary, which is funded only by demand deposits. Provided the intermediary has adequate capital, it also is perfectly safe. Deposit insurance then is both unnecessary and incapable of achieving a superior outcome to that which private agents could achieve on their own.     

Macroeconomic Impact of Bank Regulation and Supervision: A Cross-Country Investigation

Bank regulation and supervision (RS) is a formal institutional mechanism that aims to reduce the adverse selection and moral hazard risks in the banking sector. This paper offers an empirical exploration of the relationship between banking-sector performance and RS using data on the legal quality of bank regulation and supervision. The main channels via which RS affects bank performance are considered to be depositor trust, investment mobilization, and borrower discipline. An event study of up to fifty-three countries provides robust evidence that RS has significant positive effects on bank deposits and investment rate and significant negative effects on nonperforming loans.     

Bank Capital Regulation of Trading Portfolios: An Assessment of the Basel Framework

In setting minimum capital requirements for trading portfolios, the Basel Committee on Banking Supervision (1996, 2011a, 2013) initially used Value‐at‐Risk (VaR), then both VaR and stressed VaR (SVaR), and most recently, stressed Conditional VaR (SCVaR). Accordingly, we examine the use of SCVaR to measure risk and set these requirements. Assuming elliptically distributed asset returns, we show that portfolios on the mean‐SCVaR frontier generally lie away from the mean‐variance (M‐V) frontier. In a plausible numerical example, we find that such portfolios tend to have considerably higher ratios of risk (measured by, e.g., standard deviation) to minimum capital requirement than those of portfolios on the M‐V frontier. Also, we find that requirements based on SCVaR are smaller than those based on both VaR and SVaR but exceed those based on just VaR. Finally, we find that requirements based on SCVaR are less procyclical than those based on either VaR or both VaR and SVaR. Overall, our paper suggests that the use of SCVaR to measure risk and set requirements is not a panacea.     

Capital, Portfolio, and Growth: Bank Behavior Under Risk-Based Capital Guidelines

This paper examines banks' capital, portfolio and growth decisions from 1986 to 1995, when risk-based capital guidelines were proposed and implemented. Overall, we observe complementarity between equity financing and risk. We find no systematic differences in pre- and postregulation behavior consistent with banks reacting to risk-based capital standards implementation. We do find significant differences, however, between low-capital banks and other banks. For example, increases in equity generally do not lead to increases in assets unless the bank has low capital. We also find that the impact of regulatory variables, such as the ratio of equity to total assets or the of ratio risk-weighted assets to total assets, have the predicted, significant effects for low-capital banks but not necessarily for other banks.     

Jointly Optimal Regulation of Bank Capital and Liquidity

In an economy with financial frictions, banks endogenously choose excessive leverage and maturity mismatch in equilibrium, as they fail to internalize the risk of socially wasteful fire sales. Macroprudential regulators can achieve efficiency with simple linear constraints, which require less information than Pigouvian taxes. The liquidity coverage and net stable funding ratios of Basel III can implement efficiency. Additional microprudential regulation of leverage is required when bank failures are socially costly. Micro‐ and macroprudential rules are imperfect substitutes. Optimally, macroprudential policy reacts to systematic risk and credit conditions over the cycle, while microprudential policy reacts to systematic and idiosyncratic risk.     

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%).
