Deposit insurance system,risk-adjusted premium and bank systemic risk: Evidence from China

In this paper, we investigate whether and how the Deposit Insurance (DI) system and its Risk-adjusted Premium (RAP) scheme affect the systemic risk of Chinese banks. Based on bank-level panel data from 2007 to 2020 and the difference-in-differences (DID) method, we find that the establishment of the explicit DI system in China increases bank systemic risk, while the implementation of RAP alleviates this negative impact by reducing systemic risk. We further find the mechanism behind this phenomenon that bank profit acts as a mediator. We also find evidence for international heterogeneity using cross-country data and show that, as China has a longstanding implicit government guarantee, the establishment of explicit DI actually reduces the extent to which banks are protected, thus increasing bank systemic risk. Our study highlights the specificity of Chinese DI system, offers important policy implications for the design of financial safety nets in China and worldwide.     

Financial inclusion and bank profitability: Evidence from a developed market

Previous literature supports the view that financial inclusion leads to economic growth and helps alleviate poverty; however, it is still unclear whether financial inclusion increases bank profitability. Using a sample of 122 Japanese banks from 2004 to 2018, we investigate this question. We find that financial inclusion is important even in a developed economy; branch contraction reduces the profitability of Japanese banks, although the numbers of loan accounts and automated teller machines (ATMs) do not affect bank profitability. Among bank-specific variables, cost management, credit risk management, and bank size are the key drivers of profitability.     

Self-fulfilling dynamics: The interactions of sovereign spreads,sovereign ratings and bank ratings during the euro financial crisis

During the euro-area financial crisis, interactions among sovereign spreads, sovereign credit ratings, and bank credit ratings appeared to have been characterized by self-generating feedback loops. To investigate the existence of feedback loops, we consider a panel of five euro-area stressed countries within a three-equation simultaneous system in which sovereign spreads, sovereign ratings and bank ratings are endogenous. We estimate the system using two approaches. First we apply GMM estimation, which allows us to calculate persistence and multiplier effects. Second, we apply a new, system time-varying-parameter technique that provides bias-free estimates. Our results show that sovereign ratings, sovereign spreads, and bank ratings strongly interacted with each other during the euro crisis, confirming strong doom-loop effects.     

A macro-financial analysis of the euro area sovereign bond market

We estimate the ‘fundamental’ component of euro area sovereign bond yield spreads, i.e. the part of bond spreads that can be justified by country-specific economic factors, euro area economic fundamentals, and international influences. The yield spread decomposition is achieved using a multi-market, no-arbitrage affine term structure model with a unique pricing kernel. More specifically, we use the canonical representation proposed by Joslin et al. (2011) and introduce next to standard spanned factors a set of unspanned macro factors, as in Joslin et al. (forthcoming). The model is applied to yield curve data from Belgium, France, Germany, Italy, and Spain over the period 2005–2013. Overall, our results show that economic fundamentals are the dominant drivers behind sovereign bond spreads. Nevertheless, shocks unrelated to the fundamental component of the spread have played an important role in the dynamics of bond spreads since the intensification of the sovereign debt crisis in the summer of 2011.     

Commercial bank mutual fund activities: Implications for bank risk and profitability

This paper examines the risk structure of bank holding companies and the effect of mutual fund activities on bank risk and profitability over the period 1987–1994. Findings from structural change tests indicate a significant decline in bank risk occurred near the mid-point of the study. Results from a confirmatory factor analytic model employed to examine the impact of mutual fund activities on banks suggest that mutual fund activities moderated bank industry systematic risk during the sample period. Mutual fund activities also increased the profitability of banks. These results suggest that mutual funds represent a productive avenue of expansion for bank holding companies.     

The euro area sovereign debt crisis: Identifying flight-to-liquidity and the spillover mechanisms

Looking at the daily period between January 2006 and December 2012, besides the traditional credit and liquidity risks, which explain the developments of sovereign yields relative to the Bund for Greece, Ireland, Portugal, Spain and Italy, two additional factors have played a key role in the developments of euro area sovereign yield spreads: flight to liquidity benefiting the German Bund and the spillover effect from Greece. The flight to liquidity premium, which is estimated by constructing the spread between a German state guaranteed agency bond and the Bund, is behind the pricing of all euro area spreads and, specifically, is the only factor explaining the sovereign spreads for Finland and the Netherlands. The spillover effect from Greece, which is identified using complementary approaches, has contributed to developments in spreads of countries with weaker fiscal fundamentals, a lower degree of competitiveness and a higher need of foreign financing. However, a large fraction of the spillover across countries remains unexplained.     

Effect of rollover risk on default risk: Evidence from bank financing

We study the effect of rollover risk on the risk of default using a comprehensive database of U.S. industrial firms during 1986–2013. Dependence on bank financing is the key driver of the impact of rollover risk on default risk. Default risk and rollover risk present a significant positive relation in firms dependent on bank financing. In contrast, rollover risk is uncorrelated with default probability in the case of firms that do not rely on bank financing. Our measure of rollover risk is the amount of long-term debt maturing in one year, weighted by total assets. In the case of a firm that depends on bank financing, an increase of one standard deviation in this measure leads to a significant increase of 3.2% in its default probability within one year. Other drivers affecting the interaction between rollover risk and default risk are whether a firm suffers from declining profitability and has poor credit. Additionally, rollover risk's impact on default probability is stronger during periods when credit market conditions are tighter.     

The impact of revenue diversification on bank profitability and risk: evidence from MENA banking industry

The aim of this paper is to investigate the effects of revenue diversification on bank performance while shedding light on the impact of the shift towards non-interest income sources. To this end, we use a sample of 275 banks from fourteen MENA countries over 1990–2011. The model estimation using the GMM system reveals that diversification, when taken as a whole, improves bank profitability. We also split the non-interest income and we find that trading-generating business lines contribute the most to boosting profitability and stability. Engaging in non-interest-related activities worsens the benefit-cost trade-off of diversification, induced by the increased insolvency risk.     

An analysis of euro area sovereign CDS and their relation with government bonds

We compare the market pricing of euro area government bonds and the corresponding Credit Default Swaps (CDSs). In particular, we analyse the “basis” defined as the difference between the premium on the CDS and the credit spread on the underlying bond. Our sample of weekly data covers the period from January 2007 to December 2012 and contains several episodes of sovereign market distress. Overall, we observe a complex relationship between the derivatives market and the underlying cash market characterised by sizable deviations from the no-arbitrage relationship (i.e. basis equal to zero). We show that short-selling frictions explain the persistence of positive basis deviations while funding frictions explain the persistence of negative basis deviations which are observed for countries with weak public finances. Moreover, we show that the “flight-to-quality/liquidity” phenomenon in bond markets is a key driver of the large positive basis of better rated countries.     

The interest rate pass-through in the euro area during the sovereign debt crisis

We investigate the pass-through of monetary policy to bank lending rates in the euro area during the sovereign debt crisis, in comparison to the pre-crisis period. We make the following contributions. First, we use a factor-augmented vector autoregression, which allows us to assess the responses of a large number of country-specific interest rates and spreads. Second, we analyze the effects of monetary policy on the components of the interest rate pass-through, which reflect banks' funding risk (including sovereign risk) and markups charged by banks over funding costs. Third, we not only consider conventional but also unconventional monetary policy. We find that while the transmission of conventional monetary policy to bank lending rates has not changed with the crisis, the composition of the pass-through has changed. Specifically, expansionary conventional monetary policy lowered sovereign risk in peripheral countries and longer-term bank funding risk in peripheral and core countries during the crisis, but has been unable to lower banks' markups. This was not, or not as much, the case prior to the crisis. Unconventional monetary policy helped decreasing lending rates, mainly due to large shocks rather than a strong propagation.     

The impact of SEPA in credit transfer payments: Evidence from the euro area

This paper analyses the effect of the implementation process of the Single Euro Payments Area (SEPA) project on credit transfer payments in euro area countries during the period between 2008 and 2013. Using both univariate and multivariate fractional regression models, we found that, when controlling for socio-demographic, economic, technological and institutional factors, the progress in the migration to SEPA formats had a relevant positive impact on the share of payments made with credit transfers. Our results provide for the first time empirical evidence of the direct effect of the implementation of SEPA on payment habits and set the basis for the discussion of some of the possible implications of payments digitalization from both economical and societal perspectives.     

The financial Kuznets curve: Evidence for the euro area

The paper introduces a new specification of the Kuznets curve, where turning point per capita income is conditioned on the level of financial development. We then provide new evidence on income inequality dynamics for the euro area (EA) countries since the mid-1980s. We find evidence in favor of an EA-wide financial Kuznets curve, also resilient to the recent financial and economic crises. From a policy perspective, our findings highlight the importance of financial development in fostering not only economic growth, but also a more even distribution of income.     

Central bank reserves and interbank market liquidity in the euro area

The market-oriented approach promoted by the European Central Bank in the design of its refinancing operations creates incentives to credit institutions to use actively the interbank market to manage their liquidity needs. In this context, we examine the ability of the overnight segment to guarantee the timely provision of unsecured funds to banks to smoothly absorb their liquidity shocks. This paper specifically focuses on the speed of reversion of transaction costs and available depth to their equilibrium levels in this market for overnight unsecured funds. The reported evidence points to time-varying liquidity adjustments and identifies liquidity, market activity and the institutional setting of the ECB’s refinancing operations as significant determinants of the observed resiliency regimes. Our analysis also shows how the speed of mean reversion of market liquidity, by affecting the level and the volatility of the overnight market rate, also affects the anchoring of the yield curve in the euro area.     

The impact and the spillover effect of a sovereign rating announcement on the euro area CDS market

This paper analyzes the impact and the spillover effect of a sovereign rating announcement on the euro area CDS market. Through the event study technique, we demonstrate that downgrades and upgrades considerably affect financial markets. The relevance of the impact is due to the introduction of “new” information after a rating change announcement (information discovery effect) and to the role of rating in the current financial regulation (certification effect). Conversely, the CDS market does not seem to react significantly to rating warning (outlook and review) announcements. Furthermore, we find evidence of a spillover effect only after a downgrade announcement. Our results show that the size of the spillover effect is influenced by economic and financial conditions of analyzed countries and that international bank flows between EMU Members represent an important transmission channel of the spillover effect.     

Volatility risk and the value premium: Evidence from the French stock market

This paper documents that systematic volatility risk is an important factor that drives the value premium observed in the French stock market. Using returns on at-the-money straddles written on the CAC 40 index as a proxy for systematic volatility risk, I document significant differences between volatility factor loadings of value and growth stocks. Furthermore, when markets are classified into expected booms and recessions, volatility factor loadings are also time-varying. When expected market risk premium is above its average, i.e. during expected recessions, value stocks are seen riskier than their growth counterparts. This implies in bad times, investors shift their preferences away from value firms. Instead they use growth stocks as hedges against deteriorations in their wealth during those times. The findings are in line with the predictions of rational asset pricing theory and support a “flight-to-quality” explanation.     

Crash risk of the euro in the sovereign debt crisis of 2009–2010

The economic-political instability of a country, which is tied to its credit risk, often leads to sharp depreciation and heightened volatility in its currency. This paper shows that not only the creditworthiness of the euro-area countries with weaker fiscal positions but also that of the member countries with more sound fiscal positions are important determinants of the deep out-of-the-money euro put option prices, which embedded information on the euro crash risk during the sovereign debt crisis of 2009–2010. We also find evidence of information flow from the sovereign credit default swap market to the currency option market during the crisis.     

Estimating volatility clustering and variance risk premium effects on bank default indicators

The profitability and investment premium: Pre-1963 evidence

I investigate the profitability and investment premium in stock returns using hand-collected data from Moody's Manuals for 1940–1963. Controlling for value, the profitability premium emerges as important in this period. In contrast, there is no reliable relation between investment and returns, regardless of whether investment is measured using growth in total assets or book equity and even after extending the data back to 1926. In spanning regressions, factors constructed from profitability and book-to-market ratios (RMW and HML, respectively) improve the mean-variance efficient tangency portfolio but the investment factor (CMA) does not.     

Fintech,macroprudential policies and bank risk: Evidence from China

We explore the relationship between fintech, macroprudential policies, and commercial bank risk-taking. Based on system generalized method of moment modeling on a panel data of 114 commercial banks in China from 2013 to 2020, results show that there are functional differences in the impact of fintech on bank risk-taking. Payment and settlement technology (PST), capital raising technology (CRT) and investment management technology (IMT) are positively correlated with bank risk-taking. In contrast, market facility technology (MFT) negatively correlates with bank risk-taking. We also find that macroprudential policies weaken the promotion effect of CRT on bank risk-taking and strengthen the inhibition effect of MFT on bank risk-taking while having no significant moderating effect on PST and bank risk, IMT and bank risk. Further, the micro characteristics of banks (capital adequacy ratio, asset scale, liquidity level) affects the moderating strength of macroprudential policies. Various robustness tests confirm our conclusions.     

Short-term determinants of the idiosyncratic sovereign risk premium: A regime-dependent analysis for European credit default swaps

This study investigates the dynamics of the sovereign CDS term premium, i.e. difference between 10Y and 5Y CDS spreads. It can be regarded a forward-looking measure of idiosyncratic sovereign default risk as perceived by financial markets. For some European countries this premium featured distinct nonstationary and heteroskedastic pattern during the last years. Using a Markov-switching unobserved component model, we decompose the daily CDS term premium of five European countries into two unobserved components of statistically different nature and link them in a vector autoregression to various daily observed financial market variables. We find that such decomposition is vital for understanding the short-term dynamics of this premium. The strongest impacts can be attributed to CDS market liquidity, local stock returns, and overall risk aversion. By contrast, the impact of shocks from the sovereign bond market is rather muted. Therefore, the CDS market microstructure effect and investor sentiment play the main roles in sovereign risk evaluation in real time. Moreover, we also find that the CDS term premium response to shocks is regime-dependent and can be ten times stronger during periods of high volatility.
