Time series analysis for financial market meltdowns

There appears to be a consensus that the recent instability in global financial markets may be attributable in part to the failure of financial modeling. More specifically, it is alleged that current risk models have failed to properly assess the risks associated with large adverse stock price behavior. In this paper, we first discuss the limitations of classical time series models for forecasting financial market meltdowns. Then we set forth a framework capable of forecasting both extreme events and highly volatile markets. Based on the empirical evidence presented in this paper, our framework offers an improvement over prevailing models for evaluating stock market risk exposure during distressed market periods.     

Bubbles,banks and financial stability

The macroeconomic impact of rational bubbles in a limited commitment economy crucially depends on whether banks or ordinary savers hold the bubble. Banks hold the bubble asset when their leverage is high, when long-term real interest rates are low or when lax supervision allows them to enjoy high deposit insurance subsidies. When banks are the bubble-holders, this amplifies the output boom by reducing loan–deposit rate spreads while the bubble survives but also deepens the recession when the bubble bursts. In contrast, the real impact of bubbles held by ordinary savers is more muted.

Market discipline, financial crisis and regulatory changes: Evidence from Indonesian banks

Following the 1997/1998 financial crisis, Indonesian banks experienced major regulatory changes, including the adoption of the blanket guarantee scheme (BGS) in 1998, a limited guarantee (LG) in 2005, and changes in capital regulation in 1998 and 2001. We examine the impact of these regulatory changes on market discipline during the period 1995-2009. The price of deposits is used to measure market discipline in a dynamic panel data methodology on a sample of 104 commercial banks. We find a weakening of market discipline following the introduction of the BGS. The result is consistent with the deposit insurance scheme being credible in the lower capital requirement environment. The adoption of LG in a recovering economy also mitigates the role of market discipline. However, market discipline is more pronounced in listed banks than unlisted banks and in foreign banks than domestic banks. These results have important implications for banking regulation and supervision, particularly during a crisis period.     

Competition and financial stability in European cooperative banks

Cooperative banks are a driving force for socially committed business at the local level, accounting for around one fifth of the European Union (EU) bank deposits and loans. Despite their importance, little is known about the relationship between bank stability and competition for these small credit institutions. Does competition affect the stability of cooperative banks? Does the financial stability of banks increase/decrease when competition is higher? We assess the dynamic relationship between competition and bank soundness (both in the short and long run) among European cooperative banks between 1998 and 2009. We obtain three main results. First, we provide evidence in line with the competition-stability view proposed by Boyd and De Nicolò (2005). Bank market power negatively “Granger-causes” banks' soundness, meaning that there is a positive relationship between competition and stability. Second, we find that this fundamental relationship does not change during the 2007–2009 financial crisis. Third, we show that increased homogeneity in the cooperative banking sector positively affects bank soundness. Our findings have important policy implications for designing and implementing regulations that enhance the overall stability of the financial system and in particular of the cooperative banking sector.     

Systemically important banks and financial stability: The case of Latin America

This paper addresses the issue on how bank size and market concentration affect performance and risks in 17 Latin American countries between 2001 and 2008. The objective is to evaluate whether a too-big-to-fail behavior has been present in the region. Surprisingly, we do not find evidence to support a higher fragility of large Latin American banks. Our results show that systemically important financial institutions appear to outperform others in terms of both cost and profit without the need of taking more risks. This result holds even in concentrated markets, i.e., where there are few dominant banks and many others with small size in relation to the market. A highly unequal banking market in terms of assets, however, is detrimental for the performance of smaller banks and it also decreases stability of the whole system. We conclude that regulators should deal with market concentration by reducing the size gap between large and small banks, instead of dealing specifically with systemically important banks.

Private sector share of external debt and financial stability: Evidence from bank loans

In the last two decades, the private sector has contracted a substantially larger share in the total amount of foreign-currency international debt (private sector share of external debt), especially in developing countries. In this paper, I empirically examine the effect of this phenomenon on bank loan prices. I find that the private sector share of external debt negatively and significantly impacts the price of bank loans. This result supports the hypothesis that private sector debt contributes to international financial stability to a greater degree than sovereign debt. Nevertheless, this impact is canceled out in the presence of fixed exchange regimes that are unsuitable with respect to fundamentals. In such circumstances, the private sector may take advantage of capital market distortions that are maintained by official authorities and thus exposes the country to further financial instability. Additional results corroborate the observation that the gain in financial stability stems from more efficient use of funds and reduced monitoring costs.     

FDI versus exports: Evidence from German banks

We use a new bank-level dataset to study the FDI-versus-exports decision for German banks. We extend the literature on multinational firms in two directions. First, we simultaneously study FDI and the export of cross-border financial services. Second, we test recent theories on multinational firms which show the importance of firm heterogeneity [Helpman, E., Melitz, M.J., Yeaple, S.R., 2004. Export versus FDI. American Economic Review 94 (1), 300–316]. Our results show that FDI and cross-border services are complements rather than substitutes. Heterogeneity of banks has a significant impact on the internationalization decision. More profitable and larger banks are more likely to expand internationally than smaller banks. They have more extensive foreign activities, and they are more likely to engage in FDI in addition to cross-border financial services.     

Fundamental analysis of banks: the use of financial statement information to screen winners from losers

This study investigates the efficacy of a fundamental analysis-based approach to screen U.S. bank stocks. We construct an index (BSCORE) based on fourteen bank–specific valuation signals. We document a positive association between BSCORE and future profitability changes, as well as current and one-year-ahead stock returns, implying that BSCORE captures forward looking information that the markets are yet to impound. A hedge strategy based on BSCORE yields positive hedge returns for all but two years during our 1994–2014 sample period. Results are robust to partitions of size, analyst following, and exchange listing, and persist after adjusting for risk factors. We further document a positive relation between BSCORE and future analyst forecast surprises as well as earnings announcement period returns, and a negative relation between BSCORE and future performance-based delistings. Overall, our results show that a fundamental analysis-based approach can provide useful insights for analyzing banks.     

The Dynamic and Dependence of Takaful and Conventional Stock Return Behaviours: Evidence from the Insurance Industry in Saudi Arabia

This paper investigates the dynamics of volatility in the stock market using competing univariate GARCH specifications. Moreover, it provides a study of the pairwise correlation pattern of stock returns for a wide range of Saudi Arabian insurance business lines by using a dynamic DCC-GARCH model. Our results show that volatility responds asymmetrically to shocks with a persistence of variance in the stock return data, supporting the presence of irrational behaviour as well as the effectiveness of a cross-market diversification strategy. Finally, we reach a point at which, between every two-business line stock returns, there is a dynamic conditional correlation.

Political influence and banks: Evidence from mortgage lending

We show that banks expand mortgage lending in the home states of Senate Banking Committee chairs, and the effect is more pronounced in counties where the incumbent senator faces a competitive re-election race. Banks strategically target politically active borrowers. Consequently, banks’ profitability increases after favoring the incumbent politicians’ constituents, but they suffer a deterioration in mortgage asset quality in the long run. Our findings imply that political power could distort private capital allocation beyond conventional political contribution channels.     

Does the debt market assess large banks, risk? : Time series evidence from money center CDs

Uninsured bank liabilities should offer a promised yield that compensates depositors for their expected default losses. However, the conjectural, guarantees available to large U.S. banking firms makes it questionable whether large depositors should or do feel themselves exposed to credit risk. Prior papers have evaluated the determinants of bank risk premia using cross-sectional data, with relatively inconclusive results. This paper investigates the same issue in a methodologically independent fashion: using time series data on specific banks' daily offering rates during the period May 1982 through July 1988. We find that CD rates paid by large money center banks include significant default risk premia.     

Asymmetric effects of oil shocks on stock market returns in Saudi Arabia: evidence from industry level analysis

We examine the impact of oil price shocks on stock market returns in Saudi Arabia using the country-level as well as the industry-level stock market data. We find that the relation between changes in oil prices and equity returns is positive and significant at the country-level and at the industry level. Our results show that oil prices have asymmetric effects on equity returns for 4 out of 15 industrial sectors (e.g., hotel and tourism, insurance, multi-investment, and petrochemicals). These results have significant implications for investors, portfolio managers, policymakers, and corporate finance managers.     

Beyond state-owned banks: Evidence from Shanghai bank customers

In light of a reformed and liberalized banking sector in China, this article sets out to examine the role of socio-demographic factors and customers’ banking experiences and priorities in customers’ selection of banks. As state-owned banks have long dominated the banking industry, the article also investigates the receptiveness of the Shanghai Chinese towards newer commercial banks, such as the joint-stock banks, and the penetration of foreign banks into China's banking industry. Comparing customers who use state-owned banks only and those who patronize joint-stock banks, it is found that education, income, age, occupation sector and location of hometown affects customers of state-owned banks only. Further, it is also found that state-owned banks remain dominant despite the opening up of the banking sector, and perception towards state-owned banks remains favourable.     

Time series models of mortgage choice: Evidence of lender influence

Unit root, co-integration, and Granger Causality are used to test specification of a generalized time series model of mortgage choice. Unit root tests determine that both the fixed-adjustable spread (FAsp) and the proportion of ARM originations (AP) are first difference stationary. The cointegrating vector between FAsp and AP was found to be weak, raising questions regarding their long-term relationship. Causality tests determined that ARM originations Granger causes the fixed-adjustable mortgage spread (APFAsp) rather than FAspAP. This result suggests that mortgage originators adjust the current FAsp spread based on last periods allocation. The coefficient vector for this specification was unstable and became increasingly negative during the 1980s.     

Investment-cash flow sensitivity cannot be a good measure of financial constraints: Evidence from the time series

Investment-cash flow sensitivity has declined and disappeared, even during the 2007-2009 credit crunch. If one believes that financial constraints have not disappeared, then investment-cash flow sensitivity cannot be a good measure of financial constraints. The decline and disappearance are robust to considerations of R&D and cash reserves, and across groups of firms. The information content in cash flow regarding investment opportunities has declined, but measurement error in Tobin's q does not completely explain the patterns in investment-cash flow sensitivity. The decline and disappearance cannot be explained by changes in sample composition, corporate governance, or market power—and remain a puzzle.     

Cost efficiency of banks in transition: Evidence from 289 banks in 15 post-communist countries

To understand the transformation of banking in the post-communist transition, we examine the cost efficiency of 289 banks in 15 East European countries. We find that banking systems in which foreign-owned banks have a larger share of total assets have lower costs and that the association between a country’s progress in banking reform and cost efficiency is non-linear. Early stages of reform are associated with cost reductions, while costs tend to rise at more advanced stages. Private banks are more efficient than state-owned banks, but there are differences among private banks. Privatised banks with majority foreign ownership are the most efficient and those with domestic ownership are the least.
