全球金融周期与跨境资本流动

本文从全球42个主要的股票市场指数提取全球股票市场因子,作为全球金融周期的代理变量,考察全球金融周期对跨境资本总流入的影响。结果发现:(1)当全球股票市场因子(全球风险规避和不确定性)上升时,跨境资本流入显著下降;(2)一国处于经济繁荣时期,经济增速和利率处于相对较高水平,全球金融周期对资本流入的影响会减弱;(3)一国资本账户开放程度或金融发展水平越高,全球金融周期对资本流入的影响会越强;(4)更具弹性的汇率制度尽管不能完全隔绝全球金融周期的影响,但相比固定汇率制度,可提高一国抵御全球金融周期冲击的能力;(5)美国货币政策冲击是全球金融周期的重要驱动因素,并通过全球金融周期影响跨境资本流动。本文的政策含义在于,一国应夯实经济基本面、采取富有弹性的汇率制度和适当的资本管制措施,以缓解全球金融周期给资本流动带来的冲击。     

美国次贷危机的演变趋势及其启示

次贷危机对美国乃至全球金融市场都产生了深刻的影响.次贷危机经历了从美国到全球金融市场,从次级贷款市场到整个货币市场与资本市场的演变.次贷危机的直接原因是房地产泡沫的破灭,其深层次的原因是错误的货币政策、高估的信用评级以及贷款标准的放松.为防范房地产市场的金融风险,必须严格贷款的审查标准,减少证券化中的信息不对称现象,加强对非银行金融机构的监管,并将资产价格纳入货币政策的监控体系.     

Emerging economies in the 2000s: Real decoupling and financial recoupling

The paper documents an intriguing development in the emerging world in the 2000s: a decoupling from the business cycle of advanced countries, combined with the strengthening of the co-movements in the main emerging market assets that predates the synchronized selloff during the crisis. In addition, the paper tests the hypothesis that financial globalization, to the extent that it creates a common, global investor base for EM, could lead to a tighter asset correlation despite the weaker economic ties. While an examination of the impact of alternative financial globalization proxies yield no conclusive result, a closer look at global emerging market equity and bond funds show that the latter indeed foster financial recoupling during downturns, reflecting the fact that they trade near their respective benchmarks and respond to withdrawals by liquidating holdings across the board.     

The real interest rate and aggregate supply

This paper analyzes the effects of the anticipated real interest rate on aggregate supply variables, in a model where time-to-produce and variable capital utilization play a crucial role. The potential importance of the present mechanism for business cycle theory lies in its ability to generate positive co-movements of employment, capital utilization, labor productivity, output and investment. These variables are predicted to be affected negatively by the real interest rate. Reduced forms for output and employment are derived and tested with Canadian data, taking estimates of the real interest rate prevailing in the United States as the relevant exogenous price.     

全球金融周期、美国货币政策与“三元悖论”

全球金融周期存在的背景下“三元悖论”是否依然成立充满争议。本文通过构建包含银行与金融摩擦的两国DSGE模型,为考察全球金融周期的形成提供了理论依据。美国货币政策通过资本流动传导到外围国金融市场,使外围国信贷利率、银行风险承担以及杠杆率与美国银行趋同,形成全球金融周期。金融渠道的传导速度快于实体经济渠道导致外围国国内经济周期与金融周期相背离,外围国想要稳定经济就不得不与美国保持同向的政策利率变化,货币政策独立性将不再存在。随着全球经济一体化进程加速,估值效应的作用越来越明显,浮动汇率制度并不能隔离全球金融周期的影响也无法保证货币政策的独立性。在资本账户开放的情况下,外围国金融市场越不发达,受全球金融周期的影响越大,货币政策越不独立。     

Economic engagement and within emerging markets integration

We explore the co-movements between emerging markets by employing dynamic conditional correlation approach. We additionally explore the factors that might drive the conditional correlations between emerging markets. We show that trade with the high income countries is a more important driver of the co-movements between emerging markets relative to trade with other emerging markets either within or outside the geographic region of the given country. We further document that the overall health of an economy, investment and market depth explain the correlation between emerging markets. Evidence is also provided that although, the recent emerging markets and global financial crises raised the correlation between emerging markets, not all country pair correlations increased around the period of the crisis. The findings show that economic engagement as opposed to geographic proximity is more relevant in describing within emerging markets integration. The findings suggest that diversification gains could be achieved by strategically investing across some emerging markets even in crisis periods.     

China,Japan and the US Stock Markets and the Global Financial Crisis

In this paper, while focusing on the impact that the global financial crisis had on the stock markets of China, Japan, and the United States, the stock-price volatilities and linkage between these three countries are analyzed. In addition, the relationships between macroeconomic variables (real-economy variables and monetary-policy variables) and stock price volatility in each country are investigated. The estimation results of the EGARCH model revealed that although China’s stock price volatility was far greater than those of Japanese and US stock prices, China was less affected by the global financial crisis in 2007 than Japan and the United States. For China, stock price volatility was greater in the early 1990s, shortly after the stock market had been established, than in 2007 when the global financial crisis occurred. Furthermore, it has been revealed that the linkage of Chinese, Japanese, and US stock prices has increased since the global financial crisis. Moreover, Granger causality testing revealed China’s real-economy variables and monetary-policy variables do not affect China’s stock price volatility.     

What determines the Japanese corporate credit spread? A new evidence

This paper investigates the determinants of the corporate credit spreads changes in the Japanese bond markets. We show that the business cycle risk and market skewness risk affect changes in the credit spread in Japan even after controlling for the frequently used variables. We also find that the magnitude of market skewness risk is relatively higher for low-rated bonds. Our results are robust to changes in credit ratings, different maturity groups and time periods around the recent global financial crisis.     

Bank health in varying macroeconomic conditions: A panel study

Using panel data on selected Financial Soundness Indicators (FSIs) this paper investigates the potential strengths and vulnerabilities of financial intermediaries across more than 50 countries. Our econometric analysis reveals strong influence of business cycle, inflation, and real effective exchange rates, and size of the industry on capital adequacy —a core indicator of banks' financial soundness. Furthermore, our analyses provide evidence that banks' profitability is determined by a combination of macroeconomic, bank specific and industry characteristics such as business cycle, inflation, credit risk, capital adequacy, and the level of competition.     

后金融危机时代中国信用卡产业的发展

信用卡资产证券化对美国信用卡危机的爆发起到了推波助澜的作用。与美国相比,我国信用卡产业总体运行状况良好,并未受到国际金融危机的严重冲击,市场拓展速度不断加快,风险控制要求更高,外包经营需求显现。但由于多种不稳定因素依然存在,产业发展之路并不平坦。各银行在后金融危机时代的信用卡业务发展中,要平衡市场拓展与风险管理之间的关系,在转型中谋发展,适时调整经营策略,注重产品与业务创新,密切加强与有关部门的交流与合作,从各个环节实施更为严格的风险管理措施,借助后台业务外包加速产业价值链整合,促进国内信用卡产业健康发展。     

International capital flows and the boom-bust cycle in Spain

We study the joint dynamics of foreign capital flows and real activity during the recent boom-bust cycle of the Spanish economy, using a three-country New Keynesian model with credit-constrained households and firms, a construction sector and a government. We estimate the model using 1995Q1-2013Q2 data for Spain, the rest of the Euro Area (REA) and the rest of the world. We show that falling risk premia on Spanish housing and non-residential capital, a loosening of collateral constraints for Spanish households and firms, as well as a fall in the interest rate spread between Spain and the REA fuelled the Spanish output boom and the persistent rise in foreign capital flows to Spain, before the global financial crisis. During and after the global financial crisis, falling house prices, and a tightening of collateral constraints for Spanish borrowers contributed to a sharp reduction in capital inflows, and to the persistent slump in Spanish real activity. The credit crunch was especially pronounced for Spanish households; firm credit constraints tightened later and more gradually, and contributed much less to the slump.     

Bank credit default swaps and deposit insurance around the world

We investigate the impact of deposit insurance schemes on banks' credit risk – a predictor of failure and a key element in the current financial crisis. Unlike most studies, which use balance sheet measurements of risk, we adopt a forward-looking and market-based measure of bank credit risk: the credit default swap (CDS) spread. We find that banks in countries with explicit deposit insurance systems have higher CDS spreads, supporting the “moral hazard” view. The results suggest that deposit insurance design features that lessen the adverse impact are risk-adjusted premium, coinsurance systems, government-established systems, “risk-minimizing” systems, and systems with dual-funding sources. Full coverage appears to stabilize bank risk only during the financial crisis period. More stringent bank regulation, such as capital adequacy regulation and independent supervision, could reduce the undesirable impact of deposit insurance. Deposit insurance seems to help stabilize volatile markets, as evidenced during the financial crisis and in countries with greater market volatility. In addition, we find that the adverse impact of deposit insurance on bank credit risk is more pronounced for banks with low asset quality and low liquidity.     

Enter the dragon: Interactions between Chinese,US and Asia-Pacific equity markets, 1995–2010

This paper applies a variety of short-run and long-run time series techniques to data on a broad group of Asia-Pacific stock markets and the United States extending to 2010. Our empirical work confirms the importance of crises in affecting the persistence of equity returns in the Asia-Pacific region and offers some support for contagion effects. Post-Asian financial crisis quantile regressions yield substantial evidence of long-run linkages between the Shanghai market, the US market and many regional exchanges. Cointegration is particularly prevalent at the higher end of the distribution. Our results suggest that the enormous growth of the Shanghai market in the new millennium has been accompanied by a meaningful level of integration with other regional and world markets in spite of ongoing capital controls.     

Fair value accounting,fragile bank balance sheets and crisis: A model

A topic of recent interest in accounting research has been the investigation of the role of fair value accounting (FVA) in the global financial crisis. This research focused on finding a link during the crisis time-period and often states that “accounting is only a messenger”. The model presented in this paper emphasises finding the link before the crisis and “accounting as money.” Use is made of an accounting model of the economy due to the inability of standard models of monetary transmission to incorporate global financial crisis characteristics such as feedback effects, systemic risk and the centrality of the financial sector in the crisis. The model shows FVA in banks to be an accelerator that amplifies the financial cycle upswing. Feedback effects noted in the model include changes in the demand for financial instruments and changes in demand in the real economy. Minsky-like, crisis is shown to be endogenous to the model, working through the fragility of balance sheets in the real sector as well as in the financial sector. Bank balance sheet fragility is caused by bad capital driving out good capital, banks reaching for yield and the inversion of the yield curve. The model shows that the practice of not meeting rising credit demand with increasing credit supply is an essential control mechanism in the financial cycle.     

新冠肺炎疫情、金融市场震荡与金融危机

新型冠状病毒感染肺炎疫情在全球快速蔓延后,美国等国家金融市场出现大幅度震荡,历史罕见。金融市场震荡是疫情影响投资者信心,金融市场本身的风险需要释放,以及经济基本面悲观预期等因素共同作用的结果。目前来看,疫情对实体经济造成冲击,疫情应对情况也在很大程度上决定了金融市场震荡是否演化为全球金融危机,国外金融市场震荡对国内金融市场的传导需要审慎理性处理。     

Credit market imperfections and business cycle asymmetries in Turkey

The credit market imperfections have important consequences for aggregate cycles, especially for developing countries. The research on the relationship between imperfections and output dynamics at the macro-level is ample, but the lack of wide coverage micro-data sets for developing countries limits the study of aggregate implications of the micro-level capital market imperfections. This paper presents micro-evidence on the credit market imperfections in Turkey and connects these imperfections to macro-movements. The first part of the paper documents the aggregate boom–bust cycles in Turkey and shows that the non-tradable sector is more volatile over the business cycle than the tradable sector. Additionally, this sector based asymmetry is found to be strongly correlated with aggregate credit movements. To establish the connection between the sector based asymmetries and the credit markets further, the second part of the paper constructs two micro-data sets. Using structural estimation, we find that the non-tradable sector is financially more constrained than the tradable sector. With the non-tradable sector being more constrained, credit movements become an important determinant of boom–bust cycles. Therefore, we can establish that the asymmetry in the financial constraints of the different sectors at the micro-level can generate the observed asymmetrical aggregate response of sectors over the business cycle.     

Capital Flows During Quantitative Easing: Experiences of Developing Countries

A potentially important side effect of quantitative easing (QE) by the United States Federal Reserve was the expansion of capital flows into developing countries. As a result, there were widespread concerns that reversing QE might trigger financial instability in those countries. The central objective of our article is to empirically investigate this important issue by (1) examining the effect of QE on capital flows into developing Asia and (2) identifying the most significant factors that influence the effect of a QE taper tantrum on exchange rate instability. We find that capital flows into developing countries during QE were at least comparable to those before the global financial crisis. We also find that capital flows during QE and the symptoms of those capital flows such as high inflation, credit expansion, and the deterioration of the current-account balance accounted for much of the destabilizing effect of a QE taper tantrum. While there is no evidence that macroprudential policies directly reduce the destabilizing effect, they can nevertheless be useful preemptive measures.

The effect of banking crisis on bank-dependent borrowers

We provide causal evidence that adverse capital shocks to banks affect their borrowers’ performance negatively. We use an exogenous shock to the U.S. banking system during the Russian crisis of Fall 1998 to separate the effect of borrowers’ demand of credit from the supply of credit by the banks. Firms that primarily relied on banks for capital suffered larger valuation losses during this period and subsequently experienced a higher decline in their capital expenditure and profitability as compared to firms that had access to the public-debt market. Consistent with an adverse shock to the supply of credit, crisis-affected banks decreased the quantity of their lending and increased loan interest rates in the post-crisis period significantly more than the unaffected banks. Our results suggest that the global integration of the financial sector can contribute to the propagation of financial shocks from one economy to another through the banking channel.     

中国金融周期与横向关联:时空双维度相结合视角

宏观审慎政策关注各金融子市场在时间维度上的金融周期和空间维度上的横向关联。本文结合时间维度与空间维度视角,使用股票市场、货币市场、房地产市场以及信贷市场的数据,测算2001—2019年中国金融周期和横向关联的波动特征、作用关系与频域叠加机理。研究结果表明:时间维度金融周期与空间维度横向关联的波动趋势具有一致性。我国金融周期长度约为10.33年,横向关联波动周期的长度约为10.58年。从作用关系上看,首先,我国房地产周期达到波峰后,会对股票市场和信贷市场产生较强的溢出效应。随后,股市周期达到波峰后,会向房地产市场和信贷市场产生较强的溢出效应。最后,我国信贷市场接受股票市场和房地产市场溢出后,信贷周期会逐渐达到波峰。从频域叠加机理的角度看,我国金融子市场间横向关联的波动主要由中低频波段驱动,中低频波段横向关联的持续期在2个月以上。
