The effects of international off-site surveillance on bank rating changes

This article explores the determinants for off-site surveillance of short and long-term bank rating changes for rated banks in Asia, and the differences between them. An ordered logit model reveals that the CAMEL criteria for asset quality and capital adequacy and other financial variables such as asset size and mergers and acquisitions (M&A) play an important role that influences both the short-term and long-term bank ratings. Notably, it is found that higher capital to loan ratio and greater liquid asset ratio are likely to improve the probability of long-term creditworthiness, while higher impaired loan ratios are less likely to improve the short-term bank ratings. Results of the marginal effect suggest that the dividable scale helps to improve long-term creditworthiness through cross-selling tactics, synergy gains, and a better capability for fund raising.     

Measuring Credit Risk of a Bank's Corporate Loan Portfolio Using Advanced Internal Ratings Base Approach

Abstract

The use of technical and advanced approaches in the measurement of credit risk of banks' portfolios has nowadays become a very hot issue. The most recent technical report issued by the Basel Committee in May 2003 has concentrated heavily on the measurement of credit risk using either foundation or advanced Internal Ratings Base (IRB) approaches. This empirical research study attempts to measure credit risk of a bank's corporate loan portfolio, including firms from 10 different Turkish sectors. The monthly observations of the total amount of corporate loans and the total amount of corporate loans at default across various sectors are downloaded from the web page of Central Bank of Turkey (CBT) in a period of 1999-2002. This period covers 47 monthly observations since CBT has captured sectoral corporate loans beginning of 1999. Therefore, the observed sectoral default rates are needed to be simulated to obtain a nicely shaped distribution. Monte Carlo simulation is applied for 1,000 times. Based on the simulated default rates, the expected sectoral default rates are computed. Next, a credit quality rating scale is fitted into sectoral default rates distributions. Finally, the sectoral weights in the whole loan portfolio are multiplied by the expected sectoral default rates matrix, considering cross-sectoral correlations to get the total amount of the bank's credit risk and capital requirement. It is assumed that sectoral monthly default rates are a good representative of the default risk of a sample bank's corporate loan portfolio since no publicly available data on any particular bank's corporate loan portfolio composition exists. Nevertheless, this research may be a good application for measuring the credit risk of banks' corporate loan portfolios using advanced IRB approach.     

Payment shock and mortgage performance

The effect of payment shocks on subprime hybrid ARM mortgage prepayment and delinquency is examined. Using loan level data from private label securities, we modeled the effects of payment shocks on mortgage performance. Our study provided interesting empirical results in three main areas: First, we addressed the effect of payment shocks on subsequent mortgage delinquency. Second, we studied how the effect of payment shocks varies and decays over time. Third, we disentangled the impact of payment shocks based on the reason for the shocks: payment shock due to the expiration of a teaser rate (i.e. “teaser shock”) versus the payment shock due to index rate changes at the time of reset (i.e. “market rate shock”).We find that the effect of payment shock on loan performance varies by the delinquency status of the loan at the time of the shock. That is, the payment shock has the most significant effect on “current” loans rather than loans already in delinquency. Also of note, we find that the effect of a payment shock decays only gradually over time. We find that the impact of “teaser shocks” and “market rate shocks” on mortgage performance do not differ substantially, even though teaser shocks may be somewhat more predictable than market rate shocks. This suggests that either subprime ARM borrowers did not fully understand the product and the extent of the shock at the first reset date or that financially strapped borrowers used the product to speculate and were caught by the teaser shock when they were unable to refinance or sell (i.e. “flip”) their properties .The study suggests that any modification plan designed to eliminate potential payment shocks or to otherwise lower payments will be most effective for loans that are currently performing rather than loans that are already in delinquency.     

The interest rate spreads in the Czech Republic: Different loans,different determinants?

We analyze the determinants of interest rate spreads of different loan categories in the Czech Republic during 2004–2011. We employ a detailed bank supervisory dataset that allows us to construct the actual spreads for four loan categories, namely small and large corporate loans, consumer loans and mortgages, on a monthly basis. Our regression analysis shows that bank and macroeconomic characteristics matter more for setting the spreads for small corporate loans and mortgages rather than for large corporate loans and consumer loans. Interest rate risk determines the spreads for all loan categories. The global financial crisis has, to a certain extent, increased the responsiveness of spreads to interest rate risk and liquidity risk.     

Sovereign rating changes—Do they provide new information for stock markets?

The purpose of this paper is to examine the impact of sovereign rating changes on international financial markets using a comprehensive database of 42 countries, covering the major regions in the world over the period 1995–2003. In general, we find that rating agencies provide stock and foreign exchange markets with new tradable information. Specifically, rating upgrades (downgrades) significantly increased (decreased) USD denominated stock market returns and decreased (increased) volatility. Whereas the mean response is contributed evenly by the local currency stock returns and exchange rate changes that make up the USD returns, only the foreign exchange volatility was behind the USD denominated return volatility. In addition, we find significant asymmetric effects of rating announcements. The market responses – both return and volatility – are more pronounced in the cases of downgrades, foreign currency debt, emerging market debt, and during crisis periods. This study has important policy implications for international investors’ asset allocation plans and for regulatory bodies such as the Basel Committee who increasingly rely upon Moody's, Standard and Poor's and Fitch's ratings for their regulatory regimes.     

The accuracy of IMF crises nowcasts

The International Monetary Fund (IMF) provides loans to countries in economic crises as a lender of last resort. IMF loan approvals are tied to policy reforms and quantitative targets that reflect the IMF’s crisis assessment. An extensive literature scrutinizes the efficacy of IMF loan programs, instead, we examine the accuracy of the IMF’s crisis assessments (nowcasts) that predicate program designs. Analyzing an unprecedented 602 IMF loan programs from 1992 to 2019, we contradict previous findings that IMF nowcasts are generally optimistic. Disentangling the structure of the IMF’s nowcast bias, we find the IMF systematically overestimates high-growth recoveries GDPs, while low-growth recoveries for low-income countries (LICs) are underestimated. In contrast, non-LICs’ nowcasts exhibit no statistically significant optimistic and pessimistic bias. Interestingly, shorter nowcast horizons do not improve accuracy, and GDP growth nowcasts improved substantially since 2013, while inflation nowcasts remain inefficient. We also isolate the sources of IMF nowcast inefficiencies according to ((i) program objectives, ((ii) program conditionality type, ((iii) geographic regions, ((iv) global crises, and ((v) geopolitics (elections, conflicts, and disasters).     

Subprime lending and the housing bubble: Tail wags dog?

The cause of the “housing bubble” associated with the sharp rise and then drop in home prices over the period 1998–2008 has been the focus of significant policy and research attention. The dramatic increase in subprime lending during this period has been broadly blamed for these market dynamics. In this paper we empirically investigate the validity of this hypothesis vs. several other alternative explanations. A model of house price dynamics over the period 1998–2006 is specified and estimated using a cross-sectional time-series data base across 20 metropolitan areas over the period 1998–2006. Results suggest that prior to early 2004, economic fundamentals provide the primary explanation for house price dynamics. Subprime credit activity does not seem to have had much impact on subsequent house price returns at any time during the observation period, although there is strong evidence of a price-boosting effect by investor loans. However, we do find strong evidence that a credit regime shift took place in late 2003, as the GSE’s were displaced in the market by private issuers of new mortgage products. Market fundamentals became insignificant in affecting house price returns, and the price-momentum conditions characteristic of a “bubble” were created. Thus, rather than causing the run-up in house prices, the subprime market may well have been a joint product, along with house price increases, (i.e., the “tail”) of the changing institutional, political, and regulatory environment characteristic of the period after late 2003 (the “dog”).     

In search for yield? Survey-based evidence on bank risk taking

Monetary policy can have an impact on economic and financial stability through the risk taking of banks. Falling interest rates might induce investment into risky activities. This paper provides evidence on the link between monetary policy and bank risk taking. We use a factor-augmented vector autoregressive model (FAVAR) for the US for the period 1997–2008. Besides standard macroeconomic indicators, we include factors summarizing information provided in the Federal Reserve’s Survey of Terms of Business Lending (STBL). These data provide information on banks׳ new loans as well as interest rates for different loan risk categories and different banking groups. We identify a risk-taking channel of monetary policy by distinguishing responses to monetary policy shocks across different types of banks and different loan risk categories. Following an expansionary monetary policy shock, small domestic banks increase their exposure to risk. Large domestic banks do not change their risk exposure. Foreign banks take on more risk only in the mid-2000s, when interest rates were ‘too low for too long’.     

Are commercial bank lending propensities useful in understanding small firm finance?

We consider recent criticism by Berger et al. (J Bank Finance 31:11–33, 2007) of the use of commercial bank lending propensities (e.g., small business loans/total assets) as research tools. We use 2SLS cross sectional regressions with bank fixed effects to examine the relationship between small business lending and bank size. Our results indicate that the propensity to lend to small businesses declines as bank size increases, and the growth in small business lending does not keep pace with the growth in bank size. An increase in bank asset size from $1 billion to $100 billion reduces the ratio of small business loans to total loans and leases by 28 percentage points. Contrary to Berger and Black (2007) we find that most small business loans are made by small banks. For 1993 to 2006 as a whole, small banks (those under $1 billion) accounted for only 14.1% of total deposits and 9.7% of total banking assets, but they accounted for 28.4% of small business loans outstanding. This is consistent with the pattern shown by lending propensities. We conclude that these propensities remain very useful tools in research on small firm finance.     

Forecasting ultimate resource recovery

This paper considers Hubbert's model for forecasting ultimate resource recovery and its extensions by Kaufmann (1991, Resources and Energy 13, 111–127) and Cleveland and Kaufmann (1991, Energy Journal 12, 17–46). The emphasis of the paper is on econometric and forecasting issues, and it discusses alternative methods of estimating Hubbert's model. Using data on oil production in the U.S. lower 48 states, the paper reports the results of estimating the various specifications of the model and its extensions by the maximum-likelihood method, and provides the implied estimates for ultimate resource recovery and their associated standard errors. When economic factors are taken into account the estimates of ultimate resource recovery become state-dependent, and we find that in this case the estimates are higher than those obtained from the various specifications of Hubbert's original model. Although the accuracy of the estimates of ultimate recoverable reserves cannot be evaluated before oil reserves are actually exhausted, we examine how the various models estimated over the periods 1926–1985 and 1948–1985 perform in predicting oil production over the 1986–1990 period.     

Factors affecting delinquency of household credit in the U.S.: Does consumer sentiment play a role?

In this study, we provide both theoretical and empirical evidence on the determinants of household loan delinquency for home ownership, credit card and auto loans for the U.S. states in a panel framework over a period from 2003 through 2017. In particular, we examine the impact of consumer sentiments on loan delinquency rates. We show that improved current consumer sentiment significantly induce lower mortgage, credit card and automobile loan defaults in the American states subdivided into four different regions. We also find that the higher overall and expected consumer sentiment raise loan delinquencies. Implicit in this finding is the apparently excessive and inappropriate expansion of loans in the U.S. economy in the face of consumers’ optimism, which in turn, provides an intuitive understanding of the circumstances that could precede a depression or outbreak of anomalies in the financial sector. Our general findings further exhibit significant positive effect of unemployment rate and mostly adverse effect of per capita income on mortgage and automobile loan delinquency rates. The results provide some compelling evidence with regard to the effect of consumer confidence on household credit delinquency rates across various states in the U.S. and are robust to alternative measures of income and mortgage rates.     

Decomposing hospital productivity changes, 1985–1988: A nonparametric Malmquist approach

Annual data on U.S. hospitals from 1985–1988 are evaluated by ownership type—profit, nonprofit, state and local government, and U.S. Department of Veterans Affairs (VA)—for changes in hospital productivity over time. Distance functions are used to measure Malmquist indices of productivity change, which are then decomposed into indices of efficiency change and technology change. In contrast to previous studies using this approach, we allow for variable returns to scale and use both input and output orientations. We find that changes in technology dominate changes in inefficiency in determining changes in productivity.     

The bank lending channel of monetary transmission in Brazil: A VECM approach

This paper tests for the existence of a lending channel in the transmission of monetary policy in Brazil using aggregate monthly data for the period 1995:12 through 2008:6. The test is carried out in a VECM setting that allows for multiple cointegrating relationships among the variable of interest. We find evidence of two cointegrating vectors, which we identify as loan demand and supply functions by testing for a number of exclusion and exogeneity restrictions on the cointegrating relationships. Loan supply is found to be negatively related to the interbank deposit certificate rate, suggesting the existence of a lending channel for monetary transmission. The VECM's short-term dynamics show that loan demand is equilibrium-correcting. But short-term disequilibria in the supply of loans are corrected through changes in the interbank deposit certificate rate, suggesting that monetary policy plays a role in restoring equilibrium in the credit market by affecting the borrowing rate faced by banks to raise non-deposit funds.     

Spatial dependence in microfinance credit default

Credit scoring model development is very important for the lending decisions of financial institutions. The creditworthiness of borrowers is evaluated by assessing their hard and soft information. However, microfinance borrowers are very sensitive to a local economic downturn and extreme (weather or climate) events. Therefore, this paper is devoted to extending the standard credit scoring models by taking into account the spatial dependence in credit risk. We estimate a credit scoring model with spatial random effects using the distance matrix based on the borrowers’ locations. We find that including the spatial random effects improves the ability to predict defaults and non-defaults of both individual and group loans. Furthermore, we find that several loan characteristics and demographic information are important determinants of individual loan default but not group loans. Our study provides valuable insights for professionals and academics in credit scoring for microfinance and rural finance.     

Bank lending: The bank ownership focus in the pre- and post-global financial crisis periods

The objective of this research is to examine the impact of bank ownership on the composition of working capital, investment, and consumption loan types before and after the global financial crisis (GFC). The data has been grouped into pre-GFC and post-GFC sub-periods. The pre-GFC period encompasses the post-Asian crisis time period until 2006, just before the start of the GFC. The post-GFC period comprises the time period 2009 until 2016. Data were obtained from the Indonesian Banking Directory of the Indonesian Central Bank, commercial bank annual reports provided by Infobank magazine, and the Indonesian Banking Development Institute. The findings reveal the differences and changes in the composition of loan types for the different forms of bank ownership. Government-owned banks tend to focus on consumption loans, whereas foreign-owned banks outpace domestic-owned banks in the financing of working capital loans. After the GFC, government-owned banks increased their consumption loans significantly. This research augments the knowledge about loan portfolio compositions and trends pertaining to different bank types. It can serve as a benchmark and can be applied to enhance decision-making in the banking industry. Furthermore, Indonesian regulating authorities can utilize the information from a strategic and policy perspective to monitor, manage and control financial intermediation from a macroprudential perspective.     

On the determinant of bank loan contracts: The roles of borrowers’ ownership and board structures

Given the worldwide economic importance of bank loan financing, we empirically investigate the roles of borrowers’ ownership and board structure in bank loan terms through a comprehensive dataset, which includes the complete history of individual bank loan contracts for firms publicly listed in the Taiwan Stock Exchange (TWSE). We find that firms with smaller deviation in shareholder voting and cash flow rights, larger non-retail shareholding, fewer shares pledged by the board of directors, independent directors, and firms without dual boards are more likely to borrow from banks at lower spread. In addition, good governance practices are also associated with larger loan size or longer loan period, suggesting that banks take into account borrowers’ governance practices when designing loan contracts. This fact is consistent with the agency cost and information risk explanations of Bhojraj and Sengupta (2003). Furthermore, this study uncovers that the beneficial effect of good governance practices on bank loan contracting is more pronounced in borrowers with high leverage and poor rating, which implies that the monitoring role of governance is more crucial in risky firms. Our findings are robust to the various characteristics of firms and loans.     

Price support and spreads in the IPO aftermarket: An empirical microstructure study

Using the inventory components of spreads as a measure of inventory holding-risk, we test the hypothesis of Hanley et al. [Hanley, K. W., Kumar, A., & Seguin, P. J. (1993). Price stabilization in the market for new issues. Journal of Financial Economics, 34, 177–197] that price supports reduce market makers’ inventory holding-risk in the aftermarket of initial public offerings (IPOs). We find that both spreads and their inventory components are significantly smaller in the earlier periods of the IPO aftermarket than those in the later periods. More importantly, the inventory components of spreads are significantly smaller for stocks without over-allotment options (OAOs) exercised, and for stocks with lower or negative initial returns which are more likely to have price supports. The results are consistent with the price support hypothesis.

Is the secondary loan market valuable to borrowers?

In recent years, the secondary loan market has developed into an over-the-counter market where loans are not only sold but also subsequently traded. This shift away from traditional banking is altering the business of lending. Loan sales are valuable to banks because they free up capital, generate fee-based income and facilitate risk management; but they may be costly to borrowers because they negatively affect bank monitoring incentives. In this paper, however, we argue that there is another potential benefit to borrowers from loan sales. Borrowers with trading loans, in particular those with liquid loans, may “demand” a share of bank benefits from loan sales when they take out new loans as it will be easier for banks to sell these loans afterwards. We investigate this potential benefit of the secondary loan market by comparing the interest rates borrowers pay before their loans start to trade with the interest rates they pay on loans originated post-trading. Our results show that, on average, borrowers pay higher spreads on the loans they take out after the onset of trading on their loans. Importantly, our results also show that borrowers with liquid trading loans are able to borrow at lower interest rates after the onset of trading on their loans. Thus, while the banks’ decision to sell loans may initially impose a cost on borrowers, those whose loans enter the secondary loan market and become liquid benefit from an interest rate discount on their subsequent loans.
