The bright side of market power in Asian banking: Implications of bank capitalization and financial freedom

Using a sample of listed banks in the Asia-Pacific region from 2000 to 2016, this paper documents that higher market power reduces risk taking but increases loan growth and performance in banking. This highlights the "bright side" of bank market power in general. However, the positive effect of market power on bank stability is more pronounced for well-capitalized banks, although their performance tends to decline, and loan growth is unaffected by market power. Hence, bank capitalization plays an important role in strengthening financial stability due to an increase in bank market power. Moreover, banks with higher market power located in countries with a lower degree of financial freedom exhibit lower riskiness, higher loan growth, and better performance. Greater control by authorities in the financial sector is essential, not only to enhance financial stability, but also to boost financial intermediation and bank performance following an increase in bank market power.     

Financial Econometrics, Financial Innovation, and Financial Stability

Innovation in financial markets, spurred to a significant extentby developments in finance theory and financial econometrics,has played a critical role in spurring economic growth. However,the current turmoil in financial markets raises fundamentalquestions about the nature of financial innovation and the roleof policymakers in maintaining financial stability. This paperexplores these questions, focusing on the complexities of modelingfinancial risk and the potential trade-off between policiesaimed at combating short-run financial instability on the onehand and the potential financial market distortions and moralhazard that can result from such policies on the other.     

存款保险、市场竞争与银行经营稳健性

本文基于银行存款市场空间竞争模型,探讨存款保险制度的实施效果和福利效应,及其与市场竞争政策的交互作用。研究表明,政府隐性担保尽管能够保障存款人利益,但会降低存款人对银行经营稳健性的要求,使得银行追求高风险高收益资产从而降低经营稳健性;而市场化的存款保险制度通过费率与风险挂钩的激励机制,能够有效提升银行经营稳健性,同时避免过高政策成本负担,实现较高的社会福利水平。随着市场竞争强化,引入风险差别费率保险制度,在提升银行经营稳健性和增进社会福利方面的效果逐渐增强。模型分析表明,当长期允许机构自由进出市场时,政府强化竞争政策短期可能降低银行的经营稳健性,但长期内高风险银行逐渐退出市场而更有效率的低风险银行进入市场,这种柔性市场退出机制使得银行业整体经营稳健性增强。因此,在金融市场中强化竞争政策,推行并完善当前市场化的风险差别费率存款保险制度,长期内有助于在保护存款人利益的同时,提升银行稳健性和社会福利。     

Complexity and financial stability in a large random economy

I study the limit of a large random economy, in the ideal case of perfect competition, where full information is available to all market participants, and where a set of consumers invests in financial instruments engineered by banks in order to optimize their future consumption. This provides a picture of how unregulated financial innovation pushes an economy towards the ideal limit of complete markets. Hedging new products with existing products allows financial institutions to reduce the associated risk and hence the risk premium. This has the expected consequence that markets, under such ideal conditions, converge to market completeness as the repertoire of financial instruments expands. As markets approach completeness, however, two ‘unintended consequences’ also arise: (i) equilibrium portfolios develop a marked susceptibility to idiosyncratic shocks and/or parameter uncertainty and (ii) hedging engenders divergent trading volumes in the interbank market. Combining these suggests an inverse relation between financial stability and the size of the financial sector, which can be quantified within the present framework. These results suggest that even under perfect competition and symmetric information, the pursuit of market efficiency—in terms of completeness—may erode financial stability. The proliferation of financial instruments exacerbates the effects of market imperfections and, in order to prevent an escalation of perverse effects, markets may require institutional structures that become more and more substantial as their complexity expands.     

监测系统性金融风险——中国金融市场压力指数构建和状态识别

对系统性金融风险进行识别和评估,日益成为各国中央银行的核心关切。囿于数据频率,基于金融机构经营稳健性评估的金融系统性风险监测存在一定的滞后性,不利于中央银行及时进行风险应对,利用金融市场交易数据进行风险监测可极大程度克服滞后性问题。本文根据中国金融市场特点,选取债券市场、股票市场、货币市场和外汇市场17个有代表性的指标,运用经验累积分布函数法分别构造了各子市场的压力指数,以各子市场之间时变的相关关系刻画系统性金融风险的跨市场传染特征,合成金融市场压力指数,并通过建立马尔可夫区制转换模型,对金融市场压力状态进行识别。金融市场压力指数能有效反映样本域内的压力事件,并兼具稳健性、能逐日监测等优点,为监测评估系统性金融风险、选择政策实施窗口和评估政策实施效果等提供了有力工具。     

基于房地产市场的我国系统性金融风险测度与预警研究

本文阐释了基于房地产市场的系统性金融风险形成机制,据此建立了分阶段、跨部门的房地产市场的系统性金融风险网络模型,并运用2006-2017年16家上市银行数据,分析和测度了我国房价大幅下跌所引发的系统性金融风险水平和结构,构建了基于房地产市场的系统性金融风险预警指标并进行测算。研究发现:在房价下跌30%的压力情景下,我国金融体系的潜在总损失总体呈级数式上升,年均增长22.70%;基于房地产市场的系统性金融风险值(SR)呈现先上升后波动下降的总体趋势;系统性金融风险(SR)的脆弱性指标(FLI)整体呈现波浪式振荡变化,且与房地产贷款/权益整体呈反向变动,系统性金融风险(SR)的传染性指标(CTI)在2012-2017年呈持续下降趋势,且与金融市场压力指数、金融机构间资产占总资产比重呈现出高度的一致性变化趋势。最后,基于房地产市场的系统性金融风险预警指标(SRWI)值呈收敛式振荡走势,表明基于房地产市场的系统性金融风险总体可控且呈收敛式下降。     

引入国债期货合约能否发挥现货市场稳定效应?——基于中国金融周期的研究视角

我国国债期货市场能否发挥稳定现货市场功能,金融周期风险是否会改变国债期货市场对现货市场波动的影响,是投资者实施风险管理和监管部门构建市场稳定机制的重要依据。本文通过信息传递机制和交易者行为两个维度探析国债期货市场发挥稳定功能的微观机理,分析金融周期风险对衍生工具稳定功能的影响,解析引入国债期货合约能否缓解金融周期波动对国债市场冲击,同时关注我国国债期货交易机制改进与现券波动关系。研究发现:(1)我国国债期货市场已实现抑制现货市场波动的功能,金融周期风险会引发现货价格波动,国债期货市场能够降低金融周期的波动冲击;(2)改善现货市场深度和套保交易是国债期货市场发挥稳定功能的微观路径,国债期货市场增进国债预期交易量流动性、减弱非预期交易量干扰,金融周期低波动区间套保交易稳定作用受到抑制;(3)国债期货投机交易和波动溢出效应助长现货市场波动,正负期现基差对国债波动影响具有非对称特征。     

How strong are the linkages between real estate and other sectors in China?

International experience points to the critical role of stable property markets in maintaining financial stability. This paper investigates the real and financial linkages between real estate sector and other sectors. The real linkage based on input–output analysis shows that the linkages have strengthened. The financial linkages in terms of credit risk spillovers across sectors are studied by using DAG method and SVAR. We find that that credit risk in the real estate sector has large-scale spillover effects onto other sectors. Consequently, shocks to the property market could have much larger impact on the Chinese economy than suggested by headline figures.

Identifying systemically important financial institutions in Turkey

This paper examines the systemic risk of financial firms in Turkey. Using Component Expected Shortfall, we provide estimates of systemic risk in Turkey using daily data from 2005 to 2018 and a comprehensive data set encompassing 54 financial firms. Empirical results show that the preponderance of systemic risk in the sample in Turkey is due to large commercial banks. Top ten systemically important financial institutions dominate systemic risk measures in Turkey and account for more than 90 % of total risk over the sample. Consequently, the risk in the Turkish financial system is concentrated in specific financial institutions and makes close monitoring of the top firms essential. Historical incidence of systemic risk in the sample shows elevated levels of systemic risk correspond to well-known external events. Finally, a bivariate VAR model shows that systemic risk is correlated with measures of global financial risks and has significant negative effects on the real economy particularly on industrial production. This is important from a financial stability point of view in that close monitoring of the systemic risk is important in maintaining a healthy financial system and a well- functioning market economy.     

国际资本异常流动对经济增长具有非线性效应吗?--基于汇率制度和金融市场发展视角

本文基于64个经济体1999-2017年的季度面板数据,采用工具变量广义矩估计(IV-GMM)方法,从汇率制度和金融市场发展视角研究国际资本异常流动对经济增长的非线性效应。研究表明,资本流动激增显著促进了经济增长,资本流动中断、外逃和撤回对经济增长具有负向影响。有弹性的汇率制度显著减弱了四种资本异常流动情形对经济增长的冲击效应;金融市场发展显著降低了激增、中断和撤回对经济增长的冲击影响,强化了外逃对经济增长的冲击效应。随着汇率制度弹性和金融发展程度变化,新兴经济体与发达经济体资本外逃对经济增长的影响呈现明显的异质性。本文结论对于各国防范国际资本异常流动风险、维护国内经济金融稳定,以及稳步有序推进汇率市场化改革和金融市场建设具有重要的参考价值。     

The 2011 European short sale ban: A cure or a curse?

This paper examines whether the 2011 European short sale ban on financial stocks proved to be successful or had a negative impact on financial markets. We explicitly take an options market perspective and focus on market participants’ changes in beliefs and expectations. During the ban, short positions in banned stocks decreased, whereas they increased for non-banned stocks. Our results indicate that the ban increased implied jump risk levels, thereby negatively impacting the banned financial stocks. However, we also observe that after the announcement of the ban, financial contagion risk actually dropped for banned stocks. Instead of a substitution effect between regular short selling and synthetic shorting through single stock puts, we observe a migration out of single stock puts into the EuroStoxx 50 index options market. We conclude that this type of migration diversified selling pressure initially concentrated in financial stocks across a larger share of the stock market, thereby reducing systemic risks and enhancing overall financial stability.     

Global investigation on the country-level idiosyncratic volatility and its determinants

Adapting the Fama–French three-factor model to a global context, this paper investigates idiosyncratic volatility as a measure of country-specific risk, and explores its determinants by using the equity and risk data of 47 developed and emerging countries during the period 1995–2016. We find the stock market turnover to have a positive and significant impact on the country-level idiosyncratic volatility, while information disclosure and investor uncertainty avoidance degree are negatively associated with country-level idiosyncratic risk. Moreover, improvements in economic, financial, and political risks, as measured by GDP growth, FX stability, foreign debt health, and non-corruption degree decrease the country-level idiosyncratic volatility significantly. Among all sets of market structure, investor preference, and economic, financial, and political risk variables considered, we find financial risk factors, FX stability and foreign debt health, to have the highest explanatory power over the cross-sectional differences in country-level idiosyncratic risk.
