Capital Adequacy Pre- and Postcrisis and the Role of Stress Testing

The financial crisis forced the development of new approaches for determining capital adequacy in banks since extant methods clearly did not prepare banks or their supervisors sufficiently. The success of stress testing as a crisis response tool, particularly in the U.S. in 2009, has led to its adoption postcrisis as the tool of choice for assessing capital adequacy in banks and testing resiliency to economic and financial shocks. But the increased reliance on stress testing in financial peacetime has given rise to a new risk concentration, namely, in the rather narrow set of scenarios and their translation to outcomes and impact on bank financials.     

On the Contagion Effect in the US Banking Sector

By using the spatial econometrics methodology, this paper investigates the contagion of the risk taking by banks in the US banking sector during 2001 to 2012. In addition, the contagion signals up to the Subprime crisis in 2008 are analyzed and different channels of contagion are studied in order to identify fragile groups of banks. Our analysis reveals that there is no significant contagion transmitted to the whole banking system. However, we observe that the bank contagion is significantly spread locally and for the group of banks that share similar characteristics related to size and bank regulations.     

Foreign bank penetration and the lending channel in emerging economies: Evidence from bank-level panel data

This paper examines the main implications of recently increasing foreign bank penetration on bank lending as a channel of monetary policy transmission in emerging economies. Using a dynamic panel model of loan growth, we investigate the loan granting behavior of 1273 banks in the emerging economies of Asia, Latin America, and Central and Eastern Europe during the period from 1996 to 2003. Applying the pooled OLS, system GMM, and panel VAR estimators, we find consistent evidence that foreign banks are less responsive to monetary shocks in host countries, as they adjust their outstanding loan portfolios and interest rates to a lesser extent than domestic private banks, independent of their liquidity, capitalization, size, efficiency, and credit risk, and although there exists a bank lending channel in the emerging economies, it is declining in strength due to the increased level of foreign bank penetration. We also explore possible driving factors for the different responses of foreign and domestic banks to monetary policy shocks by investigating foreign banks’ different behavior during banking crises and tranquil periods, the effects of mode of entry to host countries, the home-country effects, and the response of foreign banks from OECD countries vs. all foreign countries including non-OECD countries. We suggest the access of foreign banks to funding from parent banks through internal capital markets as the most convincing explanation.     

Disclosure Regulation in the Commercial Banking Industry: Lessons from the National Banking Era

I exploit variation in the adoption of disclosure and supervisory regulation across U.S. states to examine their impact on the development and stability of commercial banks. The empirical results suggest that the adoption of state‐level requirements to report financial statements in local newspapers is associated with greater stability and development of commercial banks. I also examine which political constituencies influence the adoption of disclosure and supervisory regulation. I find that powerful landowners and small private banks are associated with late adoption of these regulations. These findings suggest that incumbent groups oppose disclosure rules because the passage of such rules threatens their private interests.     

Securitization and the balance sheet channel of monetary transmission

This paper shows that the balance sheet channel of monetary transmission is stronger for US banks that securitize their assets. This finding is different, in spirit, from the widely-found negative relationship between financial development and the strength of the lending channel of monetary transmission. Focusing on the balance sheet channel, and using bank-level observations, we find that securitizing banks are more sensitive to borrowers’ balance sheets and that monetary policy has a greater impact on this sensitivity for securitizing banks. The optimality conditions from a simple partial equilibrium framework suggest that the positive effects of securitization on policy effectiveness could be due to the high sensitivity of security prices to policy rates.     

Conference on Housing,Stability, and the Macroeconomy: International Perspectives

This article provides an introduction to the JMCB special issue on housing bubbles, the global financial crisis, and the ensuing recessions in countries that experienced housing busts. We focus on five themes that are important for policymakers and researchers alike: the domestic and international factors driving housing booms and busts, the relevance of the housing sector for the real economy, how monetary policy should react to housing booms and busts, how housing and mortgage finance reform could affect financial stability, and the broad lessons learned for macroeconomics and macroprudential policy.     

The effect of monetary policy shocks on stock prices accounting for endogeneity and omitted variable biases

A new high frequency data set is used to estimate the impact of the Fed on the level and volatility of stock prices while accounting for endogeneity and omitted variable biases and potential asymmetries. Results show that after addressing these issues, the effect of policy shocks on the level and volatility of stock returns is higher than previously reported. GARCH findings indicate that the volatility impact is tent-shaped, spiking during policy announcements and declining before and after the release. The level and conditional volatility of stock returns is found to respond asymmetrically to the type of policy shocks (timing versus future path of monetary policy) and the type of policy action (easing versus tightening).     

Asymmetric effects of federal funds target rate changes on S&P100 stock returns,volatilities and correlations

We study the effects of FOMC announcements of federal funds target rate decisions on individual stock returns, volatilities and correlations at the intraday level. For all three characteristics we find that the stock market responds differently to positive and negative target rate surprises. First, the average response to positive surprises (that is, bad news for stocks) is larger. Second, in case of bad news the mere occurrence of a surprise matters most, whereas for good news its magnitude is more important. These new insights are possible due to the use of high-frequency intraday data.     

Bank Heterogeneity and Interest Rate Setting: What Lessons Have We Learned since Lehman Brothers?

A substantial literature has investigated the role of relationship lending in shielding borrowers from idiosyncratic shocks. Much less is known about how lending relationships and bank‐specific characteristics affect the functioning of the credit market in an economy‐wide crisis. We investigate how bank and bank–firm relationship characteristics have influenced interest rate setting since the collapse of Lehman Brothers. We find that interest rate spreads increased by less for those borrowers having closer lending relationships. Furthermore, firms borrowing from banks endowed with large capital and liquidity buffers and from banks engaged mainly in traditional lending were kept more insulated from the financial crisis.     

Global Banks,Financial Shocks,and International Business Cycles: Evidence from an Estimated Model

This paper estimates a two‐country model with a global bank, using U.S. and euro area (EA) data. Empirically, a model version with a bank capital requirement outperforms a structure without such a constraint. A loan loss originating in one country triggers a global output reduction. Banking shocks matter more for EA macro variables than for U.S. real activity. Banking shocks account for about 2–5% of the unconditional variance of U.S. GDP and for 3–14% of the variance of EA GDP. During the 2007–09 recession, banking shocks accounted for about 15% of the fall in U.S. and EA GDP, and for more than a third of the fall in EA investment and employment.     

Fiscal and monetary policies and the cost of sudden stops

This article investigates the effects of monetary and fiscal policies on output growth during sudden-stop balance of payments crisis in emerging markets and developing countries. Sudden stops in capital flows, and subsequent deep recessions, are a frequent occurrence in these countries but there is no professional consensus, and little systematic empirical evidence, shedding light on the macroeconomic policy mix most likely to limit output losses during these episodes. To address this issue, we investigate 83 sudden-stop crisis in 66 countries using a baseline empirical model to control for the various determinants of output losses during sudden stops. We measure the marginal effects of policy on output losses, and find strong evidence that monetary tightening (rise in the discount rate or unsterilized rise in international reserves) and discretionary fiscal contraction are significantly correlated with larger output losses following a sudden stop. Fiscal expansion is associated with smaller output losses following a sudden stop, but monetary expansion has no discernable effect. The macroeconomic policy mix associated with the least output loss during a sudden-stop financial crisis is a discretionary fiscal expansion combined with a neutral monetary policy.     

Identifying the effects of a lender of last resort on financial markets: Lessons from the founding of the fed

We use the founding of the Federal Reserve to identify the effects of a lender of last resort. We examine stock return and interest rate volatility during September and October, when markets were vulnerable because of financial stringency from the harvest. Stock volatility fell by 40% and interest rate volatility by more than 70% following the monetary regime change. The drop is insignificant if major panic years are omitted from the analysis, however. Because business cycle downturns occurred in the same year as financial crises, our results suggest that the existence of the Federal Reserve reduced liquidity risk.     

Regulatory Arbitrage in Cross‐Border Banking Mergers within the EU

Expanding the cross‐country footprint of an organization's profit‐making activities changes the geographic pattern of its exposure to loss in ways that are hard for regulators and supervisors to observe. This paper tests and confirms the hypothesis that differences in the size and character of safety‐net benefits available to banks in individual EU countries help to account for cross‐border merger activity. Our results suggest that central bankers need to develop statistical procedures for assessing the consequences of differences in supervisory strength and weakness in partner countries. We believe that the methods used here can help in this task.     

Foreign Direct Investment and Debt Financing in Emerging Economies

The rich dynamics of capital flows is an important characteristic of business cycles in emerging market economies. In the data external debt is always procyclical, while FDI is procyclical only in normal times. We provide a microfounded rationale for this pattern by linking financial shocks to capital flows. For this purpose, we build a small open economy model in which firms are subject to borrowing constraints, and are either owned domestically or by foreign investors who purchase firms through FDI. During a financial crisis, the valuation gap per unit net worth between foreign and domestic investors widens, which triggers more FDI inflow. Our model produces business cycle moments consistent with empirical observations.     

Identifying the balance sheet and the lending channels of monetary transmission: A loan-level analysis

We make a novel attempt at comparing the strength of the lending and balance sheet channels of monetary transmission. To make this comparison, we use loan-level data to determine how borrower balance sheets and bank liquidity are related to bank lending decisions and how monetary policy can affect these relationships. The key innovation in this paper is the use of loan-level data. This enables us to measure the independent effects of the two channels and directly account for borrower balance sheets and lender liquidity instead of using proxies. Our results show that the balance sheet channel is the main mechanism through which monetary policy shocks are transmitted to the economy and that the lending channel does not play a significant role.     

The impact of foreign stock markets on macroeconomic dynamics in open economies: A structural estimation

With the increased international financial integration in recent years, bilateral financial linkages between countries may have a growing influence on their real economies. This paper employs a structural two-country New Keynesian model, which incorporates a cross-border wealth channel, to estimate the effect that foreign stock market fluctuations may have on macroeconomic variables in open economy countries.The model is estimated using Bayesian methods on a sample of open economies that can potentially be affected by changes in a larger foreign stock market: Australia, Canada, New Zealand, Ireland, Austria, and the Netherlands. The estimation allows for deviations from rational expectations and for learning by economic agents.The empirical results indicate important cross-country wealth effects for Ireland and Austria, from fluctuations in the U.S. and U.K. and in the U.S. and German stock markets, respectively; the wealth effect is largest in Ireland. The data favor, instead, specifications with no significant wealth effect for the remaining countries. Foreign stock price fluctuations, however, still play a role by affecting domestic expectations about future output gaps in all countries in the sample.     

Macroprudential Policies and Housing Prices: A New Database and Empirical Evidence for Central,Eastern, and Southeastern Europe

Several countries in Central, Eastern, and Southeastern Europe used a rich set of prudential instruments during the recent credit and housing boom and bust cycles. We construct a comprehensive database of these policy measures covering 16 countries at a quarterly frequency. We use this database to investigate whether the policy measures had an impact on housing price inflation. The measures that appeared to be effective were capital measures (minimum capital adequacy ratio, maximum ratio of lending to households to share capital) and nonstandard liquidity measures (marginal reserve requirements (MRRs) on foreign funding, MRRs linked to credit growth).     

Granger-causality in peripheral EMU public debt markets: A dynamic approach

Our research aims to analyze the possible existence of Granger-causal relationships in the behavior of public debt issued by peripheral member countries of the European Economic and Monetary Union (EMU), with special emphasis on the recent episodes of crisis triggered in the eurozone sovereign debt markets since 2009. With this goal in mind, we make use of a database of daily frequency of yields on 10-year government bonds issued by five EMU countries (Greece, Ireland, Italy, Portugal and Spain), covering the entire history of the EMU from its inception on 1 January 1999 until 31 December 2010. In the first step, we explore the pair-wise Granger-causal relationship between yields, both for the whole sample and for changing subsamples of the data, in order to capture the possible time-varying causal relationship. This approach allows us to detect episodes of significant increase in Granger-causality between yields on bonds issued by different countries. In the second step, we study the determinants of these episodes, analyzing the role played by different factors, paying special attention to instruments that capture the total national debt (domestic and foreign) in each country.     

Foreign Bank Behavior during Financial Crises

This paper studies whether lending by foreign banks is affected by financial crises. We pair a bank‐level data set of foreign ownership with information on banking crises and examine whether the credit supply of majority foreign‐owned banks that underwent home‐country crises differ systematically from those of other foreign banks. In contrast to the literature, our broad global coverage allows us to exploit variations between foreign banks; this enables us to identify an average treatment effect directly attributable to crises. Our baseline results show that banks exposed to home‐country crises between 2007–08 exhibit changes in lending patterns that are lower by between 13% and 42% than their noncrisis counterparts. This finding is robust to potential alternative explanations, and also holds, though less strongly, for the 1997/98 Asian crisis.
