Are covered bonds different from securitization bonds? A comparative analysis of credit spreads

This study compares credit spreads and pricing determinants of securitization vis-à-vis covered bonds. Our analysis reveals that although ratings are the most important pricing determinant for asset-backed securities (ABS) and mortgage-backed securities (MBS) investors place relatively more importance on contractual, macroeconomic and banks' characteristics rather than ratings in pricing covered bonds. We find evidence of a mispricing effect in structured finance markets: ABS and MBS have higher credit spreads than similarly rated public-covered bonds and mortgage-covered bonds and security prices reflect information beyond credit ratings. We find no evidence of borrowing costs affecting banks' choice between securitization and covered bonds.     

Government intervention and adverse selection costs in foreign exchange markets

An important group of traders in the foreign exchange marketis governments who often adhere to a foreign exchange rate policyof occasional interventions with otherwise floating rates. Inthis article we provide a theoretical model and empirical evidencethat government foreign exchange interventions create significantadverse selection problems for dealers. In particular, our modelshows that the adverse selection component of the foreign exchangespread is positively related to the variance of unexpected interventionand that expected intervention has no impact on the spread.After controlling for inventory and order processing costs,we find that bid-ask spreads increase with U.S. dollar and Germandeutsche mark foreign exchange rate intervention during theperiod 1976-1994. Furthermore, when the intervention is decomposedinto expected and unexpected components, we find a statisticallyand economically significant increase in spreads with the varianceof unexpected intervention, while expected intervention hasno significant impact on spreads.     

U.S. Monetary Policy and International Bond Markets

This paper analyzes how U.S. monetary policy affects the pricing of dollar‐denominated sovereign debt. We document that yields on dollar‐denominated sovereign bonds are highly responsive to U.S. monetary policy surprises—during both the conventional and unconventional policy regimes—and that the passthrough of unconventional policy to foreign bond yields is, on balance, comparable to that of conventional policy. In addition, a conventional U.S. monetary easing (tightening) leads to a significant narrowing (widening) of credit spreads on sovereign bonds issued by countries with a speculative‐grade credit rating but has no effect on the corresponding weighted average of bilateral exchange rates for a basket of currencies from the same set of risky countries; this indicates that an unanticipated tightening of U.S. monetary policy widens credit spreads on risky sovereign debt directly through the financial channel, as opposed to indirectly through the exchange rate channel. During the unconventional policy regime, yields on both investment‐ and speculative‐grade sovereign bonds move one‐to‐one with policy‐induced fluctuations in yields on comparable U.S. Treasuries. We also examine whether the response of sovereign credit spreads to US monetary policy differs between policy easings and tightenings and find no evidence of such asymmetry.     

The effect of interest rate volatility and equity volatility on corporate bond yield spreads: A comparison of noncallables and callables

This research investigates the impact of interest rate volatility upon corporate bond yield spreads. We first consider the impact of interest rate volatility upon noncallable bond spreads. Because greater interest rate volatility likely increases the volatility of the firm's debt, we hypothesize that the relation will be positive. Given that we do find a positive relation, we thus investigate whether the positive effect of interest rate volatility on yield spreads is stronger or weaker for callable bonds. We find that the effect is weaker for callable bonds. This result indicates that there is a negative relation between default spreads and call spreads, which is consistent with the theory of Acharya and Carpenter (2002), but in contrast to the theory of King (2002). Furthermore, our results for the relationship between equity volatility and yield spread tend to support Acharya and Carpenter (2002) more than King (2002).     

Financial Intermediation and the Costs of Trading in an Opaque Market

Municipal bonds trade in opaque, decentralized broker-dealermarkets in which price information is costly to gather. We analyzea database of trades between broker-dealers and customers inmunicipal bonds. These data were only released to the publicwith a lag; the market was opaque. Dealers earn lower averagemarkups on larger trades, even though dealers bear a higherrisk of losses with larger trades. We estimate a bargainingmodel and compute measures of dealer’s bargaining power.Dealers exercise substantial market power. Our measures of marketpower decrease in trade size and increase in the complexityof the trade for the dealer. (JEL G0, G24)     

The cost of private debt over the credit cycle

We identify global and regional fluctuations in international private debt flows to emerging and developing countries using data on cross-border loans and international bond issuance over 1993–2009. We use micro-level data on syndicated cross-border loans and international bond placements to estimate the effects of individual borrower characteristics as well as macroeconomic conditions on the cost of foreign borrowing and test whether these effects differ across phases of the lending cycle. First, we find that borrower characteristics associated with lower loan spreads are not necessarily associated with lower bond spreads. Second, we find differential effects of borrower characteristics between cycle phases for loans and bonds separately. Third, we find strong reductions in the cost of debt finance during periods when international debt flows are more than one standard deviation above their mean, but not for expansionary periods, when the growth rate of debt flows is increasing. We also find that higher trade ratios in the borrower's home country raise loan spreads more in periods of high credit flows but have no effect on bond spreads. At the same time, borrowers residing in countries with high investment ratios pay lower spreads on bond issuance particularly during periods of high credit flows, but we find no similar effect for loan spreads. Inflation rates, real exchange rates and previous banking crises have small impacts on loan and bond spreads.     

THE CHALLENGE OF MANAGING CREDIT SPREADS: NEW TOOLS ON THE HORIZON

Broadly speaking, "credit spread" is the excess of a bond's yield over the appropriate Treasury rate that is necessary to compensate lenders for the perceived risk of default. In the primary market, credit spreads can significantly increase a corporation's borrowing cost. In the secondary market, the effect of fluctuating spreads is of material concern to investors and traders.
Credit spreads have exhibited considerable volatility in recent years, particularly during the fall of 1998. Although the absolute levels of spreads have ranged widely in recent years, from a few basis points to several hundred depending on rating category, their volatilities have been remarkably similar—about 25 to 39% on an annual basis. In spite of this high volatility, there are currently no cost-effective means of hedging credit spreads.
The recently announced S&P Credit Indices presage a leap forward in credit derivatives. Computed from the prices of selected liquid bonds, these indices can serve as a basis for exchange-traded futures contracts and options—tools that are in great demand for managing credit spread exposure.     

Dynamic effects of idiosyncratic volatility and liquidity on corporate bond spreads

We study the dynamic impact of idiosyncratic volatility and bond liquidity on corporate bond spreads over time and empirically disentangle both effects. Using an extensive data set, we find that both idiosyncratic volatility and liquidity are critical mainly for the distress portfolios, i.e., low-rated and short-term bonds; for others only volatility matters. The effects of volatility and liquidity shocks on bond spreads were both exacerbated during the recent financial crisis. Liquidity shocks are quickly absorbed into bonds prices; however, volatility shocks are more persistent and have a long-term effect. Our results overall suggest significant differences between how volatility and liquidity dynamically impact bond spreads.     

Corporate Yield Spreads and Bond Liquidity

We find that liquidity is priced in corporate yield spreads. Using a battery of liquidity measures covering over 4,000 corporate bonds and spanning both investment grade and speculative categories, we find that more illiquid bonds earn higher yield spreads, and an improvement in liquidity causes a significant reduction in yield spreads. These results hold after controlling for common bond‐specific, firm‐specific, and macroeconomic variables, and are robust to issuers' fixed effect and potential endogeneity bias. Our findings justify the concern in the default risk literature that neither the level nor the dynamic of yield spreads can be fully explained by default risk determinants.     

News spillovers in the sovereign debt market

We study the effect of a sovereign credit rating change of one country on the sovereign credit spreads of other countries from 1991 to 2000. We find evidence of spillover effects; that is, a ratings change in one country has a significant effect on sovereign credit spreads of other countries. This effect is asymmetric: positive ratings events abroad have no discernable impact on sovereign spreads, whereas negative ratings events are associated with an increase in spreads. On average, a one-notch downgrade of a sovereign bond is associated with a 12 basis point increase in spreads of sovereign bonds of other countries. The magnitude of the spillover effect following a negative ratings change is amplified by recent ratings changes in other countries. We distinguish between common information and differential components of spillovers. While common information spillovers imply that sovereign spreads move in tandem, differential spillovers are expected to result in opposite effects of ratings events across countries. Despite the predominance of common information spillovers, we also find evidence of differential spillovers among countries with highly negatively correlated capital flows or trade flows vis-á-vis the United States. That is, spreads in these countries generally fall in response to a downgrade of a country with highly negatively correlated capital or trade flows. Variables proxying for cultural or institutional linkages (e.g., common language, formal trade blocs, common law legal systems), physical proximity, and rule of law traditions across countries do not seem to affect estimated spillover effects.     

Yield Spread and Term to Maturity: Default vs. Liquidity

The aim of this paper is the analysis of the yield spreads between Treasury and non–Treasury Spanish fixed income assets and its relationship with the term to maturity. We find a downward sloping term structure of yield spreads for investment–grade bonds that seems to be contrary to the 'crisis at maturity' theory. However, we claim that this outcome is caused mainly by the effect of liquidity on yield spreads. Once the effect of liquidity and other factors are removed we find that there is a positive relationship between default premiums and term to maturity. That result is now consistent with the existing literature.     

The sovereign ceiling and emerging market corporate bond spreads

We use the spreads of emerging market bonds traded in secondary markets to study investors' perception of country risk. Specifically, we ask whether investors apply the “sovereign ceiling,” which says that no firm is more creditworthy than its government. To do this we compare the spreads of bonds issued by firms to those of bonds issued by the firms' home governments. We find several cases where a firm's bond trades at a lower spread than that of the firm's government, indicating that investors do not always apply the sovereign ceiling. Bonds for which this is true tend to have substantial export earnings and/or a close relationship with either a foreign firm or with the home government.     

Credit risk in covered bonds

Covered bonds are a promising alternative for prime mortgage securitization. In this paper, we explore risk premia in the covered bond market and particularly investigate whether and how credit risk is priced. In extant literature, yield spreads between high-quality covered bonds and government bonds are often interpreted as pure liquidity premia. In contrast, we show that although liquidity is important, it is not the exclusive risk factor. Using a hand-collected data set of cover pool information, we find that the credit quality of the cover assets is an important determinant of covered bond yield spreads. This effect is particularly strong in times of financial turmoil and has a significant influence on the issuer's refinancing cost.     

Liquidity and price pressure in the corporate bond market: evidence from mega-bonds

Larger bonds offer greater liquidity, which should reduce their yields. A simple way for firms to reduce financing costs is to sell bonds with large face values. We find that mega-bonds are more liquid than smaller bonds. However, offering yield spreads on mega-bonds are not lower and are higher than spreads of bonds issued by similar companies. The discount applied to large new issues is consistent with price pressure effects that are also present in the secondary market prices of the issuing firm's existing bonds. Our results suggest a hidden cost to issuing very liquid bonds.     

Do significant risk warnings in annual reports increase corporate bond credit spreads? Evidence from China

Based on listed companies issuing bonds on the Shanghai and Shenzhen Stock Exchanges from 2007 to 2017, this study analyzes the relationship between significant risk warnings in Chinese companies’ annual reports and corporate bond credit spreads. The main findings are as follows. First, in the Chinese market, “substantial warnings of significant risks” can significantly improve corporate bond credit spreads, reflecting the risk-warning effect; second, state-owned property rights weaken this effect, which only pertains to listed companies with poor risk management and low information quality; third, significant risk warnings increase investors’ heterogeneous beliefs, also affecting credit spreads; and fourth, through textual analysis, it is found that the corporate bond credit spread is greater when the disclosed risk factors are more pessimistic and less similar to those of the previous year. The findings of this paper help to enrich the literature on credit spreads and risk disclosure.     

The effect of bank relationships on bond spreads: Additional evidence from Japan

This study investigates the impact of bank relationships on bond spreads using data on Japanese bond-issuing firms. In doing so, it extends the existing literature, which found that bank relationships decrease bond spreads, consistent with the view that bond investors benefit from bank monitoring, but this is not the case for investment-grade bonds in the US. This study provides evidence that the influence on the yields of investment-grade bonds varies with the type of bank relationship. In this research, a main bank is defined as a bank that is not merely the top lender to a firm but also one of the ten largest shareholders, while firms that borrow money from banks but have no ties with main banks are considered to have support bank relationships. The regression results show that although main bank relationships are not systematically associated with the yields of investment-grade bonds, support bank relationships are positively associated with them. It is suggested that, even for a sample of investment-grade bonds, a specific type of bank relationship affects bond spreads and the association between them is consistent with the view that bond investors are concerned about the hold-up problem posed by banks.     

Factors affecting the yields of emerging market issuers: Evidence from the Asia-Pacific region

We investigate the yield spread between the sovereign bonds issued in international markets by major Asia-Pacific issuers (China, Korea, Malaysia, Philippines and Thailand) and matched with near maturity benchmark U.S. Treasury bonds (2, 5, 10 year maturities) to determine the extent that various factors affect changes in credit spreads. The results suggest that the credit spreads of these sovereign bonds tend to be negatively related to changes in interest rates on U.S. benchmark bonds and positively related to changes in the slope of the yield curve. The asset and exchange rate variables were only significant for spreads on Philippine bonds where it was negatively related to changes in the local stock market index, and positively to changes in the exchange rate. The complex dynamics of these processes highlight concerns for portfolio mangers when constructing portfolios of sovereign Asian bonds by aggregating bonds of different credit ratings.     

THE SLOPE OF THE TERM STRUCTURE OF CREDIT SPREADS: AN EMPIRICAL INVESTIGATION

In this article we analyze the slope of the term structure of credit spreads. We investigate the explanatory role of interest rate, market, and idiosyncratic equity variables that the recent empirical literature highlights as important determinants of credit spread levels. This study extends the analysis and assesses its effect on credit slopes for a sample of corporate bonds. We find that these factors affect credit spreads at short and long maturities in a significantly different way. A closer inspection of the credit spread slope also reveals that it is a useful indicator of the direction of changes in future short‐term credit spreads. This evidence has important implications for the trading and risk management of portfolios of bonds with different maturities.     

Securitized banking and the run on repo

The panic of 2007–2008 was a run on the sale and repurchase market (the repo market), which is a very large, short-term market that provides financing for a wide range of securitization activities and financial institutions. Repo transactions are collateralized, frequently with securitized bonds. We refer to the combination of securitization plus repo finance as “securitized banking” and argue that these activities were at the nexus of the crisis. We use a novel data set that includes credit spreads for hundreds of securitized bonds to trace the path of the crisis from subprime-housing related assets into markets that had no connection to housing. We find that changes in the LIB-OIS spread, a proxy for counterparty risk, were strongly correlated with changes in credit spreads and repo rates for securitized bonds. These changes implied higher uncertainty about bank solvency and lower values for repo collateral. Concerns about the liquidity of markets for the bonds used as collateral led to increases in repo haircuts, that is the amount of collateral required for any given transaction. With declining asset values and increasing haircuts, the US banking system was effectively insolvent for the first time since the Great Depression.
