Does sovereign risk matter? New evidence from eurozone corporate bond ratings and zero-volatility spreads

In this paper, we empirically examine if sovereign risk matters for corporate bonds in developed economies. Using a unique panel data sample of 897 corporate bonds from eleven countries within the Economic and Monetary Union (EMU), we investigate sovereign and corporate ratings as well as zero-volatility spreads (z-spreads). In the time period from March 2006 to June 2012, we find sovereign risk to be a significant driver of corporate risk. The effect is stronger for companies with domestic revenue structure, for companies that are (partly) owned by the government, and companies active in the utility and transportation sector. Interestingly, the impact of sovereign risk on corporate risk during the acute European sovereign debt crisis period decreases if ratings are examined, but increases if z-spreads are utilized. Rating agencies seem to take a more differentiated view on individual company risk during the sovereign debt crisis, while institutional investors might want to reduce their exposure to a country in financial distress as a whole, regardless of whether sovereign or corporate bonds are held.     

The pricing dynamics of cross-listed securities: The case of Chinese A- and H-shares

We develop a non-linear Markov error correction approach to examine the general co-integration relation between the H- and A-prices of cross-listed Chinese stock issuers across the period January 1999 to March 2009. We unravel three important dimensions of this relation. These pertain to (i) the long-run expectation of the H- (to A-price) discount; (ii) the level of short-run co-movement in prices; and (iii) the magnitude of error corrections. Findings point to significant improvements in all three areas. Policy and corporate governance change appears to be the principal force driving the efficiency gains. Weakening informational asymmetries underlie much of the change in the markets’ relative pricing. In contrast, sentiment effects strongly underpin the contemporaneous response and error correction adjustments. Finally, the escalating Global Financial Crisis of 2008 appears to have not only bolstered the A- and H-markets’ short-term pricing dynamic but also temporarily increased the long-term H-share discount.     

Do option markets undo restrictions on short sales? Evidence from the 2008 short-sale ban

The effectiveness of any sanction depends on the costs of avoiding its restrictions. We examine whether bearish option strategies were substitutes for short sales during the September 2008 short-sale ban. We find a significant diminution in option volumes and a significant increase in option bid-ask spreads for banned stock relative to unbanned stock during the ban period. Apparent violations of the put-call parity bound became significantly more frequent for banned stocks during the ban period. We conclude that the ban acted as an effective restriction on trading in options.     

The alchemy of CDO credit ratings

Collateralized loan obligations (CLOs) were one of the largest and fastest growing segments of the structured finance market, fueling the 2003-2007 boom in syndicated loans and leveraged buyouts. The credit crisis brought CLO issuance to a halt, and as a result the leveraged loan market dried up. Similar to other structured finance products, investors in CLOs rely heavily on credit rating provided by the rating agencies, yet little is known about CLO rating practices. This paper attempts to fill the gap. Using novel hand-collected data on 3912 tranches of collateralized loan obligations we document the rating practices of CLOs and analyze their structures.     

Common liquidity shocks and market collapse: Lessons from the market for perps

We show how a high degree of commonality in investor liquidity shocks can diminish incentives for intermediaries to keep markets open and lead to market collapse, even without information asymmetry or news affecting fundamentals. We motivate our model using the perpetual floating-rate note market where two years of explosive growth – in which issues by high quality borrowers were placed with institutional investors and traded in a liquid secondary market – were followed by a precipitous collapse when market intermediaries withdrew due to large order imbalances. We shed new light on the trade-off between ownership concentration and market liquidity.     

Political uncertainty and firms' information environment: Evidence from China

How political uncertainty affects the supply of value relevant information about a firm is an important but unresolved question. Using an emerging market setting where political leaders are expected to exert significant influence on economic activities, we examine the effect of political uncertainty caused by turnovers of local government leaders on a firm’s information environment. We find that during periods of political uncertainty, the total amount of idiosyncratic information about a firm that is available to the market is reduced. The adverse effect on information supply is manifest in firms that are more politically dependent and stronger when uncertainty is more severe. Further, we provide evidence suggesting that firms react to political uncertainty by reducing the amount and the quality of information provided to investors. We find that information intermediaries such as financial analysts and the media have a moderating effect on the information environment as they increase the production of information during periods of political uncertainty. However, these intermediaries do not negate the net loss of information.     

Transatlantic systemic risk

In this paper we study systemic risk for the US and Europe. We show that banks’ exposures to common risk factors are crucial for systemic risk. We come to this conclusion by first showing that relations between US and European banks are smaller than within each region. We then show that European banks react more strongly to the onset of the financial crisis than US banks. Regarding the consequences of systemic risk, we show that dependence between the banking sector and a wide range of real sectors is limited. Our results imply that regulators and supervisors should address international bank dependencies arising from common risk factors, while recessions in real sectors due to bank defaults should be a secondary concern.     

What slice of the pie? The corporate bond market boom in emerging economies

This paper studies the determinants of shifts in debt composition among emerging market non-financial corporates. We show that the determinants of bond market access in EMs vary with global cyclical conditions and across local and foreign currency markets. We find that the role for institutions and macro fundamentals in creating an enabling environment for markets increased during the post-crisis period for local currency markets. Foreign bank linkages additionally explain why local currency bond markets increasingly substituted for banks in channeling liquidity to EMs. In the case of foreign currency markets, in turn, global cyclical factors accounted for most of the variation. Furthermore, a country’s relative sensitivity to global factors appears to vary with the size of its foreign currency bond market rather than local fundamentals. Our results highlight the risk of capital flow reversal in those EMs that benefited from the upturn in the global financial cycle mostly due to the relative size of their bond markets rather than strong fundamentals.     

Credit Spreads in Illiquid Markets: Model and Implementation

This paper presents a methodology for estimating a family of credit spread term structures in a market with few transactions. The authors propose partitioning the market into risk classes and modeling credit spread term structures for each risk class using a multifactor Vasicek model with some common and some risk class-specific factors. The approach uses information on the cross section and time series of corporate bonds in all the risk classes to estimate the term structure of credit spreads in each risk class. The model is jointly estimated using an extended Kalman filter and implemented using Chilean corporate and government bonds.     

Market fragility and international market crashes

We extend the Pukthuanthong and Roll (2009) measure of integration to provide an estimate of systemic risk within international equity markets. Our measure indicates an increasing likelihood of market crashes. The conditional probability of market crashes increases substantially following increases of our risk measure. High levels of our risk measure indicate the probability of a global crash is greater than the probability of a local crash. That is, conditional on high levels of systemic risk, the probability of a severe crash across multiple markets is larger than the probability of a crash within a smaller number of markets.     

Determinants of sub-sovereign bond yield spreads – The role of fiscal fundamentals and federal bailout expectations

This paper investigates how bailout expectations affect the extent to which yield spreads for bonds issued by sub-sovereign entities within fiscal federations price in fundamentals related to default risk. The question is analysed both across and within federations using a novel dataset for sub-sovereign governments that includes Australian states, Canadian provinces, Swiss cantons, German Länder, US states, Spanish communities, and Indian states. The paper finds that sub-sovereign debt and deficit levels relative to GDP are important drivers of sub-sovereign spreads. However, the weight assigned by financial markets to fundamentals when pricing sub-sovereign bonds is reduced when the institutional set-up of the federation allows for bailouts. Moreover, within federations, the market’s expectation of a federal bailout and the capacity of the federal government to provide support to the weaker members of the federation similarly affect the extent to which fundamental factors are priced into spreads. The paper shows that the positive link between debt and risk premia tends to break down when sub-sovereign government debt rises above certain thresholds. This could reflect the market’s expectation of a federal bailout as fundamentals deteriorate. Additionally, larger sub-sovereign entities tend to pay higher premia as fundamentals worsen which could be linked to the limited capacity of the federal government to provide support as the size of the expected bailout increases. A pattern of rising risk premia as fundamentals worsen is also found for sub-sovereign entities when the central government faces borrowing constraints.     

Uncertainty,market structure,and liquidity

In this study we show that market uncertainty [measured by the Chicago Board Options Exchange Market Volatility Index (VIX)] exerts a large market-wide impact on liquidity, which gives rise to co-movements in individual asset liquidity. The effect of VIX on stock liquidity is greater than the combined effects of all other common determinants of stock liquidity. We show that the uncertainty elasticity of liquidity (UEL: percent change in liquidity given a 1% change in VIX) has increased around regulatory changes in the US markets that increased the role of public traders in liquidity provision, reduced the minimum allowable price variation, weakened the affirmative obligation of NASDAQ dealers, and abolished the specialist system on the NYSE.
