Do the business cycle and revenue diversification matter for banks’ capital buffer and credit risk: Evidence from ASEAN banks

We examine the association of the business cycle and revenue diversification with the banks’ capital buffer and credit risk for a sample of banks from the Association of Southeast Asian Nations (ASEAN) region from 1998 to 2018, using 2847 banking firm–year observations. We find that ASEAN region banks react anticyclically in adjusting their capital buffer levels and credit risk. We find revenue diversification benefits and that banks, through revenue diversification, can reduce their credit risk while achieving capital savings when confronting economic downturns. Our results offer support for the Basel III accord. However, the relations revealed are somewhat moderated by the regulatory quality, competition, and phase of the business cycle encountered by ASEAN region banks.     

Contagion effect on bond portfolio risk measures in a hybrid credit risk model

This paper illustrates how modelling the contagion effect among assets of a given bond portfolio changes the risk perception associated to it. This empirical work is developed in a hybrid credit risk framework that incorporates recovery rate risk. Dependence structures among firms and between external shocks affecting firms together are considered. The presence of correlations among firm leverage ratios and the interrelation between default probabilities and recovery rates produces clusters of defaults with low recovery rates. This has a major impact on standard risk measures such as Value-at-Risk and conditional tail expectation. Consequently, an appropriate measurement of the contagion has a tremendous effect on the capital requirement of many financial institutions.     

中国影子银行发展成因实证分析——基于2002~2012年月度数据

综合运用格兰杰因果检验和分位数回归技术对我国影子银行的各种影响因素进行实证分析。结论表明,我国影子银行是在金融二元结构和利率管制格局下,金融活动主体为规避监管、分散风险以及投机套利而进行金融创新的产物。利率管制是促成我国影子银行发展的根本原因,经济结构变迁、经济周期运行及宏观调控政策在总量与结构层面作用于金融资源供求关系,通过扩大或收缩监管套利空间,也对影子银行规模变动产生了重要影响。     

Financial stability and Basel II

The Basel II Advanced Internal Ratings (AIRB) approach is compared to capital requirements set using an equilibrium structural credit risk model. Analysis shows the AIRB approach undercapitalizes credit risk relative to regulatory targets and allows wide variation in capital requirements for a given exposure owing to ambiguity in the definitions of loss given default and exposure at default. In contrast, the Foundation Internal Ratings Based (FIRB) approach may over-capitalize credit risk relative to supervisory objectives. It is unclear how Basel II will buttress financial sector stability as it specifies the weakest regulatory capital standard for large complex AIRB banks.      

Diversification,Fee Income,and Credit Union Risk

Australian credit unions (CUs) have introduced new fee generating activities, increased transaction fees on existing products, and diversified into residential mortgages. Using DeYoung and Roland’s degree of total leverage and other risk measures we find that more diversified CUs have lower risk and return. CUs that increase the revenue share of transaction fees (matched by a lower share of personal loan interest) increase risk and reduce returns while those that increase residential lending revenues reduce both risk and returns. There is also evidence of scale related economies with risk decreasing and returns increasing with CU size.JEL classification: G21Disclaimer: The views and opinions in this paper are those of the authors and do not necessarily reflect those of APRA.     

Does institutional ownership matter for international stock return comovement?

We study the link between international stock return comovements and institutional investment. We test whether the rise of institutional ownership has increased cross-country correlations and decreased cross-industry correlations. Using stock-level institutional holdings across 45 countries during the 2001–2010 period, we find that industry and global factors are relatively more important the country factors in explaining stock return variation among stocks with higher institutional ownership. Industry diversification strategies are more beneficial than country diversification strategies for stocks with high institutional ownership. We show that cross-border portfolio investment is a powerful force of international capital market integration and convergence of asset prices.     

Pricing credit-risky bonds and spread options modelling credit-spread term structures with two-dimensional Markov-modulated jump-diffusion

The relationship between company hazard rates and the business cycle becomes more apparent after a financial crisis. To address this relationship, a regime-switching process with an intensity function is adopted in this paper. In addition, the dynamics of both interest rates and asset values are modelled with a Markov-modulated jump-diffusion model, and a 2-factor hazard rate model is also considered. Based on this more suitable model setting, a closed-form model of pricing risky bonds is derived. The difference in yield between a risky bond and risk-free zero coupon bond is used to model a term structure of credit spreads (CSs) from which a closed-form pricing model of a call option on CSs is obtained. In addition, the degree to which the explicit regime shift affects CSs and credit-risky bond prices is numerically examined using three forward-rate functions under various business-cycle patterns.

Is ex-post credit risk affected by the cycles? The case of Italian banks

The objective of this research is to empirically examine if both credit and business cycle affect the ex-post credit risk (i.e. non-performing loans) in the banking system of Italy for the period 1995Q1–2014Q1. The increase in NPLs post-2008 has put into question the robustness of many European banks and the stability of the whole sector. It still remains a serious challenge, especially in Italy which is one of the countries that hit by the financial crisis. By employing fixed and random effects and a dynamic GMM estimation as econometric methodologies I find results that underline common causes for NPLs. Higher NPLs in Italy are mostly due to worse macroeconomic conditions (i.e. bad phase of business cycle) and due to excess credit. Through a Granger causality test, my arguments found even more support. Such findings can be helpful when designing macro-prudential as well as NPL resolution policies.     

Macroeconomic cycles and the stock market’s reaction to monetary policy

This paper examines cyclical variation in the effect of Fed policy on the stock market. We find a much stronger response of stock returns to unexpected changes in the federal funds target rate in recession and in tight credit market conditions. Using firm-level data, we also show that firms that face financial constraints are more affected by monetary shocks in tight credit conditions than the relatively unconstrained firms. Overall, the results are consistent with the credit channel of monetary policy transmission.     

Market discipline in international banking regulation: Keeping the playing field level

The focus of this article is the debt market as a powerful disciplinarian source for large and complex banking organizations around the world. We empirically study the interactions between reinforcing banks’ market discipline and preserving a level playing field in international banking. Our approach consists of conducting cross-country comparisons of the secondary market prices sensitivity to market measures of bank risk (traditional and financial strength ratings). The results are generally consistent with the market discipline paradigm. However, much progress still needs to be made (especially in Japan and certain European countries) in order to make the level playing field principle compatible with the reinforcement of market discipline on an international level.     

Efficiency and Risk in Latin American Banking: Explaining Resilience

Using an unbalanced panel of 272 commercial banks, we estimate cost and revenue efficiency scores for fifteen Latin American and Caribbean countries over the period 2001-8. Using Granger causality techniques, we find evidence that in the face of increased risk and lowered capital, banks have tended to improve cost efficiency. The results also indicate that cost efficiency is negatively related with revenue efficiency, both dynamically and across countries. Market concentration is related to greater revenue efficiency. In the absence of developed capital markets, competitive forces and strengthened regulation seem to be forcing cost-efficiency improvements. Banks with market power, however, seem to be able to pass on to customers the cost of raising capital buffers and provisioning for risk.     

Discussion of “Capital mobility and international sharing of cyclical risk”

This is a comment on “Capital mobility and international sharing of cyclical risk.” The comment focuses on the authors' choice of portfolio adjustment costs in explaining limited international risk sharing. The comment raises two main issues. One is that investors hold large gross positions that vary significantly in value over the business cycle. The second is that it is difficult to identify portfolio adjustment costs from trade costs within the authors' environment.
