美国次贷危机传导机理分析

美国次贷危机爆发后,迅速在国内和国际传导蔓延。从国内看,危机先从信贷市场传导至资本市场,又从资本市场回传到信贷市场,并对实体经济造成冲击。从国际看,危机通过金融渠道、贸易渠道和心理渠道向世界各国扩散。分析本次危机的传导机理,对日后有效防范金融危机的产生和蔓延具有理论和现实意义。     

U.S. investors and global equity markets

This study examines international equity flows of U.S. residents to emerging markets in Latin America and Asia and to developed markets in Europe, Canada, and Japan. The major issues addressed are (1) appropriate means of measuring relationships between returns and flows, (2) role of volatility in these relationships, and (3) effects of the Asian crisis. Basic findings include: (1) the information contribution argument is stronger than the feedback trading argument (flows affect returns more than past returns affect flows), (2) volatility of flows and of returns are not of major importance, (3) the Asian crisis effects are important and strongest for Asia followed by developed markets and by Latin America, and (4) regional measures and U.S. returns play significant roles in international equity flows to many countries.     

What drives U.S. financial sector volatility? A Bayesian model averaging perspective

We investigate the driving forces behind the quarterly stock price volatility of firms in the U.S. financial sector over the period from 1990 to 2017. The driving forces represent a set of 28 economic indicators that are routinely used to detect financial instability and crises and correspond to the development of the financial, monetary, real, trade and fiscal sector as well as to the development of the bond and equity markets. The dimensionality and model choice uncertainty are addressed using Bayesian model averaging, which led to the identification of only seven variables that tend to systematically drive the stock price volatility of financial firms in the U.S.: housing prices, short-term interest rates, net national savings, default yield spread, and three credit market variables. We also confirm that our results are not an artefact of volatility associated with market downturns (for negative semi-volatility), as the results are similar even when market volatility is associated with market upsurge (positive semi-volatility). Given the identified drivers, our results provide supporting empirical evidence that dampening credit cycles might lead to decreased volatility in the financial sector.     

Trade Credit,the Financial Crisis,and SME Access to Finance

Mounting evidence indicates that firms, particularly SMEs, suffered from a significant credit crunch during this crisis. We analyze for the first time whether trade credit provided an alternative source of external finance to SMEs during the crisis. Using firm‐level Spanish data we find that credit constrained SMEs depend on trade credit, but not bank loans, and that the intensity of this dependence increased during the financial crisis. Unconstrained firms, in contrast, are dependent on bank loans but not on trade credit.     

我国银行金融数据跨境流动的法律规制

随着全球范围内银行金融数据跨境流动日益频繁,欧盟和美国在整体数据跨境流动规则下,形成了各自不同的银行金融数据跨境流动规制模式。我国也在自身国情基础上,建立了将"数据主权、数据保护与发展数字经济相统一"的整体数据跨境流动规制理念,但仍存在不同部门的规制思路有待进一步协调,以及对不同类型的银行金融数据跨境流动进行规制的针对性有待进一步提高等问题。本文认为,未来对银行金融数据的跨境流动的规制应在明确金融监管部门特殊规制权限的基础上,建立以下有区别的规制模式:针对基于商业需求而产生的银行金融数据跨境流动,应当在"知情、同意"的前提下,原则上允许跨境流动,并实行备案管理;针对基于数据流入国监管机构要求而产生的跨境流动,除存在国际协定或其他国际合作形式外,原则上不予认可。     

The exposure of international banks to cross-country interdependencies: An empirical analysis of overdue claims

We analyze the performance outcomes on UK-owned bank lending to borrowers in 17 foreign countries, 1991–2000. Our analysis is unique in its use of bank-specific data on overdue claims in individual countries. Results indicate that credit repayment in a country can be influenced by exports to, and economic activity in, other countries linked by trading relationships. This extends prior research on bank credit performance from a global perspective to the perspective of interdependencies between countries linked by trade. It also extends research on the international transmission of financial shocks from the analysis of credit quantity to the analysis of credit quality.     

Did the financial crisis affect the market valuation of large systemic U.S. banks?

We examine the impact of the financial crisis on the stock market valuation of large and systemic U.S. bank holding companies (BHCs). Using the Bertsatos and Sakellaris (2016) model of fundamental valuation of bank equity, we provide evidence that the financial crisis has not altered investors’ attitudes towards bank characteristics. In particular, before, during, and after the crisis, investors in large and systemic U.S. BHCs seemed to penalize leverage, albeit temporarily. Both before and after the crisis, they reward size in the short run. This pattern is appearing only briefly during the crisis. We also show that bank opacity plays no role in market valuation either in the short run or in the long run. Last but not least, we find evidence that stress testing has been informative to the market and that those BHCs that failed at the post-crisis stress tests were not subsequently valued differently by the market.

Spillovers of U.S. unconventional monetary policy to emerging markets: The role of capital flows

We employ a structural global VAR model to analyze whether U.S. unconventional monetary policy shocks, identified through changes in the central bank’s balance sheet, have an impact on financial and economic conditions in emerging market economies (EMEs). Moreover, we study whether international capital flows are an important channel of shock transmission. We find that an expansionary policy shock significantly increases portfolio flows from the U.S. to EMEs for almost two quarters, accompanied by a persistent movement in real and financial variables in recipient countries. Moreover, EMEs on average respond to the shock with an easing of their own monetary policy stance. The findings appear to be independent of heterogeneous country characteristics like the underlying exchange rate arrangement, the quality of institutions, or the degree of financial openness.     

The impact of the European sovereign debt crisis on banks stocks. Some evidence of shift contagion in Europe

This paper analyzes the influence of the recent European sovereign debt crisis on banks’ equity returns for 15 countries. Our data span the period December 14th 2007 - March 8th 2013 that encompasses several episodes of economic and financial turmoil since the collapse of the subprime credit market. Our contribution to the literature is twofold. First, we use an explicit multifactor model of equity returns extended with a sovereign risk factor. Second, we adopt a Smooth Transition Regression (STR) framework that allows for an endogenous definition of crisis periods and captures the changes in parameters associated with shift contagion. We find that the negative impact of the European sovereign debt crisis on banks’ equity returns has been mostly confined to European banks, whereas U.S. banks appear to be unharmed by its direct impact and may even have benefited from it. Besides, we find some evidence of shift contagion across Europe.     

Information Effects During the U. S. Subprime Crisis

We investigate the impact of the U. S. subprime crisis on the stock markets of the Asia-Pacific countries on various event dates. Using data from Hong Kong, Indonesia, Malaysia, Singapore, and Taiwan, we find that the subprime crisis negatively affects these stock markets and investor behavior, especially in Hong Kong and Taiwan. In addition, the subprime crisis generally works through more financial linkages than trade linkages. However, when the subsamples are classified according to industry, this result exists only for the banking industry, but both financial and trade linkages become important to explain the impact of the crisis on the manufacturing industry.     

Net Equity and Debt Flows to Emerging Market and Developing Economies in the Post-Crisis Era

We investigate the determinants of net equity and debt flows into 60 emerging and developing countries during 1986–2012, with a special focus on the period following the onset of the global financial crisis (GFC). Our results controlling for endogeneity show that net equity flows to emerging markets were mostly influenced by global risk factors, while net debt flows were affected by country-specific factors. We further distinguish the factors that were more pronounced in determining net portfolio flows to emerging markets since the GFC. The US real interest rate had significant spillover effects on net equity flows after the GFC. An increase in country’s domestic credit attracted net debt inflows before the GFC, while it was associated with net equity outflows after the GFC. We also find that capital controls moderated net debt flows since the GFC.     

How common are credit-less recoveries? Firm-level evidence on the role of financial markets in crisis recovery

We study firm recoveries from systemic sudden stops in developing countries, where firms' cash flows suffer exogenous shocks. Contrary to macro studies suggesting that output recovery precedes that of the financial sector, firm-level data shows that only in less than a third of firms, operating cash flows recover without a recovery in external credit, and even these firms have access to other sources of cash. Specifically, firms with high prior short-term debt exposure do experience a sharp reduction in short-term credit but increase operating cash flows during a crisis. Firms with high prior cash holdings experience negative cash flows and deplete their cash holdings. Thus, firms' financial prepositioning predicts recovery in cash flows and is consistent with trade-off theories of capital structure and with precautionary motives for cash holdings. We find no support for the maturity mismatch hypothesis, which predicts that firms with high short-term debt should have harder recoveries post crisis.     

The global financial crisis: Causes,threats and opportunities. Introduction and overview

This essay introduces the papers presented at a conference held in April 2009 on the global financial crisis. The issue begins with four articles that survey the key events and analyze important issues around the crisis from the context of four asset classes: the equity market, fixed income market, foreign exchange market, and emerging markets. The goal is to provide readers with a reference source for understanding what happened in each asset class, when and why it happened, and the consequences. The second group of papers provides in-depth analysis of specific aspects of the crisis. These studies include issues such as the FX carry trade, macro shocks and capital flows, Taylor rules in a low-inflation environment, and the credit boom that preceded the crisis.     

Trade credit and the joint effects of supplier and customer financial characteristics

We examine how access to bank credit affects trade credit in the supplier–customer relationships of U.S. public firms. For identification, we use exogenous liquidity shocks to supplier firms in the form of staggered changes to interstate bank branching laws. Using a variety of tests, we show that supplier firms with greater access to banking liquidity offer more trade credit to their customers. We also show that when bank branching restrictions are relaxed in the supplier’s state, the supplier–customer relationship is more likely to survive.     

INTERNATIONAL BANK FLOWS TO EMERGING MARKETS: INFLUENCE OF SOVEREIGN CREDIT RATINGS AND THEIR REGIONAL SPILLOVER EFFECTS

We examine whether changes in sovereign credit assessments help determine international bank flows to emerging countries. We focus on the bank flows of G7 countries to a sample of 55 emerging market borrowers for 1995–2008. We find evidence indicating that sovereign credit rating revisions have significant and positive influences on international bank flows from developed markets even after controlling for other determinants. In addition, we find strong regional rating spillover effects. Ratings improvements in one emerging market region tend to reduce bank flows to the other regions. However, there is an exception from the Asia Pacific to Eastern Europe.     

Trade credit and bank credit: Evidence from recent financial crises

This paper studies the effect of financial crises on trade credit for a sample of 890 firms in six emerging economies. Although the provision of trade credit increases right after a crisis, it contracts in the following months and years. Firms that are financially more vulnerable to crises extend less trade credit to their customers. We argue that the decline in aggregate trade credit ratios is driven by the reduction in the supply of trade credit that follows a bank credit crunch, consistent with the “redistribution view” of trade credit provision, whereby bank credit is redistributed via trade credit from financially stronger firms to weaker firms.     

Macroeconomic consequences of the real-financial nexus: Imbalances and spillovers between China and the U.S.

Relying on quarterly data since 1998 we estimate, for China and the U.S., small scale econometric models that economize on the number of variables employed and yet are rich enough to provide useful insights about spillover effects between the two countries under different maintained assumptions about the exogeneity of the macroeconomic relationship between them. We conclude that inflation in China responds to credit shocks. Indeed, the monetary transmission mechanism in China resembles that of the U.S. even if the channels through which monetary policy affects their respective economies differ. We also find that the monetary policy stance of the PBOC was helpful in mitigating the impact of the 2008–9 global financial crisis on China's financial conditions. Finally, spillovers from the U.S. to China are significant and originate from both the real and financial sectors of the U.S. economy.     

Hot money in bank credit flows to emerging markets during the banking globalization era

This paper investigates the relative importance of hot money in bank credit and portfolio flows from the US to 18 emerging markets over the period 1988–2012. We deploy state-space models à la Kalman filter to identify the unobserved hot money as the temporary component of each type of flow. The analysis reveals that the importance of hot money relative to the permanent component in bank credit flows has significantly increased during the 2000s relative to the 1990s. This finding is robust to controlling for the influence of push and pull factors in the two unobserved components. The evidence supports indirectly the view that global banks have played an important role in the transmission of the global financial crisis to emerging markets, and endorses the use of regulations to manage international capital flows.     

The determinants of private capital flow volatility in Sub-Saharan African countries

The study investigates the underlying factors of patterns of volatility for FDI, portfolio equity and cross-border bank lending inflows for sub-Saharan African countries using a panel framework with data from 1990 to 2011. No other study has focussed exclusively on sub-Saharan Africa when investigating the determinants of private capital flow volatility. This study is further unique in that it employs clearly-delineated cross-border bank lending data from the Bank of International Settlements’ (BIS) Locational Banking Statistics that has not been used by similar prior studies. The findings of the study are as follows: (1) global liquidity lowers FDI volatility while private sector credit increases volatility; (2) global liquidity increases portfolio equity volatility with growth and the quality of macroeconomic policies found to be important pull factors in lowering volatility; and (3) the quality of macroeconomic policies and trade openness are important pull factors in lowering cross-border bank lending volatility while financial openness increases volatility.
