Financial Spillovers to Emerging Markets During the Global Financial Crisis

In this paper potential financial linkages between liquidity and bank solvency measures in advanced economies and emerging market (EM) bond and stock markets are analyzedduring the latest crisis. A multivariate GARCH model is estimated in order to gauge the extent of co-movements of these financial variables across markets. The findings indicate that the notion of possible de-coupling (in the financial markets) had been misplaced. While EM stock markets reached their peak in the last quarter of 2007, interlinkages between funding stress and equity markets in advanced economies and EM financial indicators were highly correlated and have seen sharp increases during specific crisis moments.

Transmission of Liquidity Shocks : Evidence from the 2007 Subprime Crisis

We examine the linkages between market and funding liquidity pressures, as well as their interaction with solvency issues surrounding key financial institutions during the 2007 subprime crisis. A multivariate GARCH model is estimated in order to test for the transmission of liquidity shocks across U.S. financial markets. It is found that the interaction between market and funding illiquidity increases sharply during the recent period of financial turbulence, and that bank solvency becomes important.

Oil Prices and Bank Profitability: Evidence from Major Oil-Exporting Countries in the Middle East and North Africa

This paper analyzes the relationship between oil price shocks and bank profitability. Using data on 145 banks in 11 oil-exporting MENA countries for 1994-2008, we test hypotheses of direct and indirect effects of oil price shocks on bank profitability. Our results indicate that oil price shocks have indirect effect on bank profitability, channeled through country-specific macroeconomic and institutional variables, while the direct effect is insignificant. Investment banks appear to be the most affected ones compared to Islamic and commercial banks. Our findings highlight systemic implications of oil price shocks on bank performance and underscore their importance for macroprudential regulation purposes in MENA countries.

Global Market Conditions and Systemic Risk

This article examines several key global market conditions, such as a proxy for market uncertainty and measures of interbank funding stress, to assess financial volatility and the likelihood of crisis. Using Markov regime-switching techniques, it shows that the Lehman Brothers failure was a watershed event in the crisis, although signs of heightened systemic risk could be detected as early as February 2007. In addition, we analyse the role of global market conditions to help determine when governments should begin to exit their extraordinary public support measures.

The Effectiveness of Central Bank Interventions During the First Phase of the Subprime Crisis

This paper provides evidence that central bank interventions had a statistically significant impact on easing stress in unsecured interbank markets during the first phase of the subprime crisis which began in July 2007. Extraordinary liquidity provisions, such as the Term Auction Facility by the Federal Reserve, are analyzed. First a decomposition of the Libor-OIS spread indicates that credit premia increased in importance as the crisis deepened. Second, using Markov switching models, central bank operations are then graphically associated with reductions in term funding stress. Finally, bivariate VAR and GARCH models are adopted to econometrically quantified these impacts. While helpful in compressing Libor spreads, the economic magnitudes of central interventions have overall not been very large.

Financial Intermediation in the Pre-Consolidated Banking Sector in Nigeria

This paper uses unique bank-by-bank balance sheet and income statement information to investigate the intermediation efficiency in the Nigerian pre-consolidated banking sector during 2000-05. The author analyzes whether the Central Bank of Nigerias policy of recent banking consolidation can be justified and rationalized by looking at the determinants of spreads. A spread decomposition and panel estimations show that the reform of the banking sector could be the first step to raise the intermediation efficiency of the Nigerian banking sector. The author finds that larger banks have enjoyed lower overhead costs, increased concentration in the banking sector has not been detrimental to the spreads, both increased holdings of liquidity and capital might have led to lower spreads in 2005, and a stable macroeconomic environment is conducive to a more efficient channeling of savings to productive investments.

Bank Efficiency, Ownership, and Market Structure: Why are Interest Spreads so High in Uganda?

Using a unique bank-level data set on the Ugandan banking system during 1999-2005, the authors explore the factors behind consistently high interest rate spreads and margins. While foreign banks charge lower interest rate spreads, they do not find a robust and economically significant relationship between privatization, foreign bank entry, market structure, and banking efficiency. Similarly, macroeconomic variables can explain little of the over-time variation in bank spreads. Bank-level characteristics, on the other hand, such as bank size, operating costs, and composition of loan portfolio explain a large proportion of cross-bank, cross-time variation in spreads and margins. However, time-invariant bank-level fixed effects explain the largest part of bank variation in spreads and margins. Further, the authors find tentative evidence that banks targeting the low end of the market incur higher costs and therefore higher margins.

Sovereign Wealth Funds and Financial Stability - An Event Study Analysis

This paper examines financial stability issues that arise from the increased presence of sovereign wealth funds (SWFs) in global financial markets by assessing whether and how stock markets react to the announcements of investments and divestments to firms by SWFs using an event study approach. Based on 166 publicly traceable events collected on investments and divestments by major SWFs during the period from 1990 to 2009, the paper evaluates the short-term financial impact of SWFs on selected public equity markets in which they invest. The impact is analyzed on different sectors (financial and nonfinancial), actions (buy and sell), market types (developed and emerging markets), and level of corporate governance (high and low score). Results, based on these 166 events, show that there was no significant destabilizing effect of SWFs on equity markets, which is consistent with anecdotal evidence.

Recent Credit Stagnation in the Mena Region; What to Expect? What Can Be Done?

This paper examines the recent credit slowdown among Middle Eastern and North African (MENA) countries from three analytical angles. First, it finds that, similar to other regions and to its past history, a credit boom preceded the current slowdown, and that a protracted period of sluggish growth is likely going forward. Second, it uncovers a key role played by bank funding (deposit growth and external borrowing slowed considerably) but whose effect was frequently dampened by expansionary monetary policy. Third, bank-level fundamentals - capitalization and loan quality - helped to explain differences in credit growth across banks and countries.

Is Banks’ Home Bias Good or Bad for Public Debt Sustainability?

Motivated by the recent increase in domestic banks’ holdings of domestic sovereign debt (i.e., home bias) in the European periphery, this paper analyzes implications of banks’ home bias for the sovereign’s debt sustainability. The main findings, based on a sample of advanced (AM) and emerging market (EM) economies, suggest that home bias generally reduces the cost of borrowing for AMs and EMs when debt levels are moderate to high. A worsening of market sentiments appears to diminish the favorable impact of home bias on cost of borrowing particularly for EMs. In addition, for AMs and EMs, higher home bias is associated with higher debt levels, and less responsive fiscal policy. The findings suggest that home bias indeed matters for debt sustainability: Home bias may provide fiscal breathing space, but delays in fiscal consolidation may actually delay problems until debt reaches dangerously high levels.
