Rating the UK: the British government's sovereign credit ratings, 1976–8

The UK received its first sovereign credit ratings in 1978. Despite having required financial assistance from the International Monetary Fund only 18 months earlier, the British government managed to secure ‘triple‐A’ ratings from both Standard and Poor's and Moody's. Both assessments of creditworthiness reflected improving economic conditions but also British efforts to influence the sovereign ratings process. The Bank of England and the Treasury sought guidance from American investment banks to prepare for the ratings process and then controlled the flow of information available to the rating agencies accordingly, stressing the strengths of the national economy and downplaying the weaknesses. The British government subsequently launched its first bond issue in the New York market to high levels of investor demand. Consideration of these achievements complements the historiography concerning Britain's economic fortunes in the late 1970s. Scrutiny of events also offers a rare glimpse into the confidential sovereign ratings process. Both agencies relied on a combination of quantitative and qualitative evaluations of the UK. In addition, this article highlights the existence of a unique period in the history of sovereign credit ratings. From 1974 to 1985, the ratings industry enjoyed a cautious revival focused principally on ‘triple‐A’ borrowers.     

Sovereign Credit Ratings and Private Capital Flows to Low‐income Countries

Abstract: As low‐income countries obtain sovereign credit ratings in increasing numbers, this paper examines the potential effects on the composition and volume of private capital flows. Sovereign credit ratings are unlikely to overcome the informational asymmetries that impede private capital flows, and due to new international capital adequacy rules may actually raise the costs of capital for private borrowers. Nevertheless, they could help develop local and regional securities markets and assist mature private borrowers in hitherto unrated countries. Also, there may be beneficial disciplining effects on policy makers, and a growing differentiation between countries subject to an Africa‐wide risk premium.     

Exchange market pressure, trade, sovereign credit ratings, and U.S. exports in banking services

As a leader in providing banking services in the global market, it is important to understand the variables that influence U.S. exports in banking services. This paper examines the influence that trade, sovereign credit ratings, and exchange market pressure have on U.S. exports of banking services. The empirical evidence indicates that higher trade activity and a higher sovereign credit rating reduce U.S. exports of banking services. The results also suggest that exchange market pressure positively affects U.S. exports of banking services. Tests for individual and random effects across units suggest most of the variation in the estimators is within units.     

Managerial Ability and Credit Ratings

We test whether credit rating analysts consider managerial ability as a credit risk factor and find that higher‐ability managers obtain more favorable credit ratings. Controlling for past performance, these results suggest that managerial ability is itself a significant credit rating factor. Cross‐sectional analyses indicate that managerial ability is beneficial specifically in firms facing financial or competitive pressure. We find that high‐ability managers mitigate the adverse impact on ratings of other credit risk factors including negative earnings and low interest coverage. Our results contribute to a growing literature documenting economic benefits to hiring and retaining high‐quality management.     

Lessons from the great recession for developing countries

Many lessons can be taken from the Great Recession and the Euro crisis with respect to both pre‐crisis and post‐crisis policies. Appropriate measures can reduce the risk of crisis in individual countries, the severity of crises, and the magnitude of needed adjustments. These include an appropriate exchange rate policy (flexibility is highly desirable), ensuring the soundness of the financial system, not allowing expansion of credit at too high a rate, adopting structural fiscal budgeting policies, and avoiding dangerous sovereign debt build‐up. On the crisis resolution side, the lesson that stands out is the desirability of decisive and credible action to address the causes of the crisis. The issues that arise when the banking and financial system is weakened in the run‐up to crisis are extremely difficult, especially when sovereign debt is unsustainable. Therefore, while the important lesson is to avoid overly expansive credit build‐up during good times, in the event of a crisis, it is important that the health of the banks be restored as quickly as possible and that a viable supervision and resolution framework be put in place.     

Sovereign credit spreads and the composition of the government budget

This paper investigates the relationship between sovereign credit spreads and the composition of the government budget. The key result of this paper is that governments that invest more and spend less on consumption have significantly lower sovereign credit spreads. This finding is in accordance with the endogenous growth theory, which predicts a positive impact of government investment and a negative impact of government consumption on the long-term growth rate. Finally, a broader tax base significantly reduces sovereign credit spreads. A possible explanation may be that governments with more tax receipts are less likely to have liquidity problems to finance their debt charges.

Ambient Influences on Municipal Net Assets: Evidence from Panel Data

Governments’ net assets balances are viewed as a measure of fiscal health and have been linked to municipal credit ratings. This study explores the extent to which ambient socioeconomic factors are captured in aggregated restricted and unrestricted net assets balances (termed “liquid net assets”) to understand why such balances are relevant to credit analysts and others. We model liquid net assets balances using observable nonaccounting factors (e.g., unemployment rates) to learn whether they reflect such influences. We use panel data for fiscal years 2007–2011 so our results comprehend effects of recent economic fluctuations. We find that liquid net assets balances impound a rich array of influences, bearing a positive association with the mayor‐council form of government, community wealth, the incidence of property crimes, and increases in governments’ business‐type net assets. Liquid net assets balances bear a negative association with liabilities for postemployment benefits, unemployment, and violent crime. The results indicate that net assets balances capture noteworthy debt burden, administrative, and socioeconomic influences and, as such, have meaning beyond their basic accounting interpretation.     

The credit relationship between Henry III and merchants of Douai and Ypres, 1247–70

This article looks at an important but neglected aspect of medieval sovereign debt, namely ‘accounts payable’ owed by the Crown to merchants and employees. It focuses on the unusually well‐documented relationship between Henry III, King of England between 1216 and 1272, and Flemish merchants from the towns of Douai and Ypres, who provided cloth on credit to the royal wardrobe. From the surviving royal documents, we reconstruct the credit advanced to the royal wardrobe by the merchants of Ypres and Douai for each year between 1247 and 1270, together with the king's repayment history. The interactions between the king and the merchants are then analysed. The insights from this analysis are applied to the historical data to explain the trading decisions made by the merchants during this period, as well as why the strategies of the Yprois sometimes differed from those of the Douaissiens.

Assessing Local Government Debt Risks in China: A Case Study of Local Government Financial Vehicles

Strong credit expansion in China after the recent global financial crisis has brought local government financial vehicles (LGFV) into the spotlight. Rapid growth of LGFV has triggered concern about local government indebtedness, banks' asset quality and, more broadly, China's medium‐term financial stability and sovereign risk. This paper constructs a unique firm‐level dataset to evaluate the country's local government debt. We find an uneven distribution of LGFV, which are concentrated in the coastal areas, and a deterioration of their debt repaying ability from 2010 to 2012. We use principal component analysis (PCA) along with multivariate discriminate analysis (MDA) to identify the credit risk of LGFV based on conventional financial variables as well as local governments' fiscal status. We also estimate the safe boundaries of debt bearing at the provincial government level. The estimations reveal more severe local government debt risks in the middle‐western provinces and higher risks associated with LGFV at the municipal and county levels. Although it is very unlikely that there will be a national debt crisis in China, the high risk of LGFV should be noted and effectively controlled by improving the fiscal transparency of local governments and reforming the fiscal system.     

Forecasting Risk in Earnings

Conventional measures of risk in earnings based on historical standard deviation require long time‐series data and are inadequate when the distribution of earnings deviates from normality. We introduce a methodology based on current fundamentals and quantile regression to forecast risk reflected in the shape of the distribution of future earnings. We derive measures of dispersion, asymmetry, and tail risk in future earnings using quantile forecasts as inputs. Our analysis shows that a parsimonious model based on accruals, cash flows, special items, and a loss indicator can predict the shape of the distribution of earnings with reasonable power. We provide evidence that out‐of‐sample quantile‐based risk forecasts explain incrementally analysts' equity and credit risk ratings, future return volatility, corporate bond spreads, and analyst‐based measures of future earnings uncertainty. Our study provides insights into the relations between earnings components and risk in future earnings. It also introduces risk measures that will be useful for participants in both the equity and credit markets.     

Credit ratings and information asymmetry on the Chinese syndicated loan market

We study whether local credit ratings alleviate information asymmetry inherent in the fast growing Chinese market by examining the syndicate structure of loans issued by Chinese borrowers in 2003–2011. Despite the common criticism regarding the quality of Chinese credit ratings, our results suggest that they serve an important role in reducing information asymmetry in the market between corporate insiders and outside borrowers.     

Credit Ratings and CEO Risk‐Taking Incentives

This study examines the sophistication of rating agencies in incorporating managerial risk‐taking incentives into their credit risk evaluation. We measure risk‐taking incentives using two proxies: the sensitivity of managerial wealth to stock return volatility (vega) and the sensitivity of managerial wealth to stock price (delta). We find that rating agencies impound managerial risk‐taking incentives in their credit risk assessments. Assuming other things equal, a one standard deviation increase in vega (delta) will lead to an approximately one‐notch (two‐notch) rating downgrade. In addition, we evaluate the significance of credit ratings in the design of CEO compensation. Our findings suggest that rating‐troubled firms will gear down managerial incentives of risk seeking. In particular, other things equal, a rating downgrade to the lower edge of the investment category (i.e., BBB?) in the immediate prior year will bring about an approximately 51 percent reduction of vega incentive from options newly granted to the CEO in the current year. However, we find no evidence that firms' rating concerns significantly affect delta. Given the significance of credit ratings in the marketplace and their close connection to accounting, the findings of the current study advance our understanding, not only of how sophisticated rating agencies are in incorporating forward‐looking information (i.e., vega and delta) into risk assessments, but of how influential the raters are in changing firms' compensation policies. The findings also have implications on the role of accounting in constraining excessive managerial risk taking with improved disclosures on managerial compensation.

Information contents of collateral under heterogeneous borrower qualities on the bank loans market in China

We analyze the risk of default and provision of collateral for bank loans made to firms of varied credit qualities using a unique dataset obtained from a major state-owned commercial bank in China. Both high and low quality borrowers provide collateral more often than medium quality debtors do. Using models that explicitly incorporate heterogeneous borrower qualities, we find a positive relation between collateralization and risk of default for loans issued to debtors with low credit ratings. In contrast, collateral provided by debtors with high credit ratings is negatively associated with the risk of default. These results suggest that low quality borrowers may be required to provide collateral at the bank's request to mitigate moral hazard problem. On the other hand, high quality borrowers may provide collateral willingly to signal quality in order to mitigate adverse selection problem when competing for getting access to bank loans. Our findings shed new lights on different information contents of collateral on the bank loans market of China, and have important implications for banks in screening, contracting and monitoring the risk of commercial loans for clients with diverse credit qualities.     

Deciphering Tax Avoidance: Evidence from Credit Rating Disagreements

This study investigates the role of tax avoidance in the credit‐rating process and whether differences exist in how rating agencies account for the risk relevance of tax avoidance. Using a sample of initial credit ratings assigned to public debt issuances during 1994–2013, our evidence is consistent with Moody's Investors Service and Standard & Poor's assessing the costs and benefits associated with tax avoidance differently from one another, resulting in more frequent and pronounced rating agency disagreement. Rating agency disagreement over tax avoidance is most evident when it is accompanied by relatively high levels of uncertain tax positions, foreign activities, research and development activities, or tax footnote opacity. We also find evidence that decreases (increases) in tax avoidance or tax footnote disclosure opacity are positively (negatively) associated with the convergence of split ratings. This suggests that firms can exacerbate or mitigate rating agency disagreement subsequent to bond issuance. Our study complements prior research by examining why sophisticated information intermediaries disagree about the risk relevance of tax avoidance. It also sheds light on how firms can influence rating agencies’ understanding of tax avoidance.     

Does Other Comprehensive Income Volatility Influence Credit Risk and the Cost of Debt?

We examine the usefulness of other comprehensive income (OCI) to debt investors in nonfinancial companies. Motivated by Merton's (1974) real options framework, we construct a measure of incremental OCI volatility, designed to capture the effect of OCI on overall firm asset volatility, which is a primary driver of credit risk in Merton's (1974) model. We find that the volatility of incremental OCI influences the likelihood of default, credit ratings, and the cost of debt. Overall, our evidence suggests that creditors use information from OCI in their assessment of firm credit risk and in pricing debt contracts.     

结构性违约、信用分层与评级机构的策略性反应——来自中国信用债市场的证据

2014年以来,以主要集中于民企的"结构性违约"宣告了中国信用债市场刚性兑付的"结构性打破",债券市场进入了新的发展阶段。利用2013-2017年债券数据,本文深入分析了结构性违约对评级机构行为和效率的影响,主要有如下发现：首先,信用评级的市场公信力会因政府隐性担保导致的"刚性兑付"而削弱;其次,结构性违约爆发之后,信用评级的整体效率有所提升,但在不同发行主体呈现分化,对于非城投类企业,信用评级对发行利差的影响显著增大,意味着评级公信力的显著提升,而对于城投类企业,评级效率并未明显改善;进一步研究表明,出现这种情况的原因在于评级机构在违约后采取了差异化的评级策略,对于违约风险较大的非城投类债券,评级机构倾向采取"收紧评级"的策略;对于违约风险较低的城投债,评级机构倾向于采取"放宽评级"的策略。这种策略性行为是导致市场"信用分层"的重要原因,并有可能推升民营企业的融资成本。     

Sovereign Spreads and Contagion Risks in Asia

In the aftermath of the recent global financial turmoil, sovereign spreads have exhibited a significant degree of volatility. This paper explores how much of these movements in the spreads of Asian economies reflected shifts in global risk aversion or country‐specific risks, directly from worsening fundamentals, or indirectly from spillovers originating in other sovereigns, or risks and uncertainty surrounding their exchange rates. This analysis finds that earlier in the crisis, the increase in market‐implied contagion led to an increase of sovereign bond yields relative to the swaps. Higher‐rated sovereign bonds in Asia benefited from the flight to quality that accompanied the increase in global risk aversion during this period. Once the systemic risks in the financial sectors worldwide were contained, the risk of sovereign spillovers eased, which, together with a fall in perceived currency‐related risks, led to a fall in sovereign bond yields relative to swaps yields across the board. Comparing the situation to that of Europe, the present paper concludes that the debt crisis in the euro area has not affected the perception of sovereign risks of Asian economies. In fact, a fall in exchange rate and spillover risks, combined with stronger fundamentals, have led to a continued normalization of Asian sovereign spreads since the height of the financial crisis.
