Sovereign to Corporate Risk Spillovers

The first Greek bailout on April 11, 2010 triggered a significant reevaluation of sovereign credit risk across Europe. We exploit this event to examine the transmission of sovereign to corporate credit risk. A 10% increase in sovereign credit risk raises corporate credit risk on average by 1.1% after the bailout. The evidence is suggestive of risk spillovers from sovereign to corporate credit risk through a financial and a fiscal channel, as the effects are more pronounced for firms that are bank or government dependent. We find no support for indirect risk transmission through a deterioration of macroeconomic fundamentals.     

Public debt,bailouts, and common bonds

We look at a model where countries of different sizes provide local public goods with positive spillovers. Matching grants can give rise to optimal expenditure levels, but countries can induce bailouts. We study the characteristics of these bailouts in a subgame-perfect Nash equilibrium and how these characteristics are affected by the introduction of common bonds. Partial substitution of common for sovereign bonds has two implications. First, it lowers the average and marginal borrowing costs of countries which may be eligible for bailouts. This effect leads to higher borrowing in these countries irrespective of their bailout expectations. Second, the lower borrowing costs mitigate the incentives of countries to induce a bailout and, therefore, constrain the parameter set for which a soft budget constraint equilibrium exists. As a result, the introduction of common bonds can also be in the interest of those countries that provide the bailouts.     

Is it punishment? Sovereign defaults and the decline in trade

Sovereign defaults are associated with declines in defaulting countries trade. Are these declines the result of trade sanctions as the trade sanctions argument of sovereign borrowing would suggest? We devise an empirical strategy to evaluate this issue based on the idea that if trade sanctions are causing the declines, bilateral trade with creditor countries should fall more than trade with other countries. We find that this is not the case. The analysis does not yield much evidence of broader punishment strategies including a league of major creditors either. These results contradict the predictions of the trade sanctions theory of sovereign borrowing.     

IMF bailouts, contagion effects, and bank security returns

The Asian financial crisis that started in mid-1997 led to the International Monetary Fund's (IMF) bailout of three previously high growth economies: Thailand, Indonesia, and Korea. Using data for 114 large banks from 16 countries worldwide, we study the impact of the IMF bailout announcements on bank security returns. The announcement that the IMF will provide a rescue package for a country has a positive impact on domestic bank stock prices in the countries receiving the bailouts, which supports the view that these bailouts help ameliorate systemic risk. Our results show that banks in the nonbailout countries generally experience either insignificant or negative abnormal returns, which is contrary to the view of opponents of IMF bailouts, who argue that these bailouts lead to moral hazard among international banks. Our results support the view that the reaction of investors differs from bank to bank, but consistent with the contagion and the heterogeneous creditor hypotheses, banks' stock price reactions are not proportional to their loan exposure.     

An analysis of IMF-induced moral hazard

Three channels through which the IMF rescue package may affect international lending can be distinguished: debtor-side moral hazard, creditor-side moral hazard, and debtor and creditor-side moral hazard. We show that if the rescue package fully benefits the debtor, no credit contract between him and the creditor arises. The other two kinds of moral hazard, where the creditor receives the rescue package either fully or in part, increase the scale of international lending relative to the case where no rescue package is forthcoming. The increase is larger if the creditor receives the whole rescue package than if it is shared between the creditor and the debtor.These results are based on the analysis of two sequential credit relationships, the first one between a bank and a government and the following one between the IMF and the government. Each of these credit relationships is characterized by asymmetric information and modeled by a moral hazard model. The two moral hazard models are linked by considering the different channels of the IMF rescue package.     

The effect of IMF lending on the probability of sovereign debt crises

This paper explores empirically how the adoption of IMF programs affects sovereign risk over the medium term. We find that IMF programs significantly increase the probability of subsequent sovereign defaults by approximately 1.5–2 percentage points. These results cannot be attributed to endogeneity bias as they are supported by specifications that explain sovereign defaults and program participation simultaneously. Furthermore, IMF programs turn out to be especially detrimental to fiscal solvency when the Fund distributes its resources to countries whose economic fundamentals are already weak. Our evidence is therefore consistent with the hypothesis that debtor moral hazard is most likely to occur in these circumstances. Other explanations that point to the effects of debt dilution and the possibility of IMF triggered debt runs, however, are also possible.

Contagion during the Greek sovereign debt crisis

We examine the impact of news about Greece and news about a Greek bailout on bank stock prices in 2010 using data for 48 European banks. We identify the twenty days with extreme returns on Greek sovereign bonds and categorise the news events during those days into news about Greece and news about the prospects of a Greek bailout. We find that, except for Greek banks, news about Greece does not lead to abnormal returns while news about a bailout does, even for banks without any exposure to Greece or other highly indebted euro countries. This finding suggests that markets consider news about the bailout to be a signal of European governments' willingness in general to use public funds to combat the financial crisis. Sovereign bond prices of Portugal, Ireland, and Spain respond to both news about Greece and news about a Greek bailout.     

Exchange Rate Policy and Sovereign Bond Spreads in Developing Countries

This paper analyzes how exchange rate policy affects the issuance and pricing of sovereign bonds for developing countries. We find that countries with less flexible exchange rate regimes pay higher spreads and are less likely to issue bonds. Changing a free‐floating regime to a fixed regime decreases the likelihood of bond issuance by 5.5% and increases the spread by 88 basis points on average. Countries with real overvaluation have higher spreads and higher bond issuance probabilities. The effects of real overvaluation on sovereign bonds tend to be magnified for countries with fixed exchange rate regimes.     

基于道德风险视角的资本类逆周期监管工具的比较分析

2007—2009年的全球金融风暴使监管者最终认识到宏观审慎管理的重要性,其主要目的是缓解顺周期问题。然而,我们认为宏观审慎管理可以兼顾"大而不能倒"的金融机构引发的道德风险问题。本文对这一问题做了初步性的探索,结论为:时间可变的资本充足率不能很好地解决"大而不能倒"的金融机构所面临的道德风险问题;或有资本可以部分解决金融机构的道德风险问题;救助保险基金能够很好地解决道德风险问题。     

Question the Unquestionable Beauty of A Collective Proceeding for All Sovereign Debt Claims

The new challenges presented by the current Eurozone crisis and the NML Capital v. Argentina case are likely to shift the international community's attention from holdout behavior in foreign bonds restructuring to inter‐creditor issues. In the past years, many academics, and nongovernmental organizations concerned with debt relief, have put forward proposals to create a bankruptcy regime for states. But none of these proposals has seriously examined what rules should apply to treatment among creditors. Moreover, all insist that there must be a collective proceeding for all sovereign debt claims, without explaining why. This approach is simply taken for granted, as it is one of the fundamental principles of bankruptcy law. The article questions this orthodoxy through examining the nature of sovereign debt crisis, the feature of the limited pool of sovereign assets, and the nonliquidable fact of the sovereign debtor. It also argues that the common pool problem does not exist in the sovereign debt context.     

On the role and effects of IMF seniority

We analyze the IMF as a lender to countries in financial distress highlighting the fact that it is a senior creditor. An advantage of delegating senior lending in a single institution rather than on competitive markets is that it would be able to reach the socially optimal solution. This would require the IMF not to intervene when the crisis is severe enough. However, a commitment device might be needed to achieve the socially optimal solution. If IMF lending were done for all shocks, the country would be always ex-post better off but lenders would be worse off when the country situation is either good or weak, which is consistent with empirical evidence. Anticipation of senior lending might make the country better off by preventing inefficient liquidation. However it might actually hurt the country ex-ante and too much rescuing in the future could lead to too little lending in the present which is contrary to the moral hazard critique.     

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.     

The reaction of emerging market credit default swap spreads to sovereign credit rating changes

This paper examines the effect of sovereign credit rating change announcements on the CDS spreads of the event countries, and their spillover effects on other emerging economies’ CDS premiums. We find that positive events have a greater impact on CDS markets in the two-day period surrounding the event, and are more likely to spill over to other emerging countries. Alternatively, CDS markets anticipate negative events, and previous changes in CDS premiums can be used to estimate the probability of a negative credit event. The transmission mechanisms for positive events are the common creditor and competition in trade markets.     

Bailing out conflicted sovereigns

How should sovereign bailouts take account of the effects bailouts have on policy reforms? Conflicted recipient governments complicate bailout choices because some reforms that spur growth reduce rents that benefit government decision makers. Our model takes account of whether bailout generosity and policy reforms are strategic substitutes, strategic complements or both, and each case implies a different optimal bailout contract, which generally cannot achieve First Best. Conditional forgiveness of some loan payments when economic outcomes are sufficiently favorable can achieve outcomes closer to First Best, and this is so for a small ex ante amount of the bailout subsidy.     

Bailout uncertainty in a microfounded general equilibrium model of the financial system

This paper develops a micro-founded general equilibrium model of the financial system composed of ultimate borrowers, ultimate lenders and financial intermediaries. The model is used to investigate the impact of uncertainty about the likelihood of governmental bailouts on leverage, interest rates, the volume of defaults and the real economy. The distinction between risk and uncertainty is implemented by applying the multiple priors framework to beliefs about the probability of bailout.Results of the analysis include: (i) An unanticipated increase in bailout uncertainty raises interest rates, the volume of defaults in both the real and financial sectors and may lead to a total drying up of credit markets. (ii) Lower exante bailout uncertainty is conducive to higher leverage, which in turn raises moral hazard and makes the economy more vulnerable to expost increases in bailout uncertainty. (iii) Bailout uncertainty affects the likelihood of bubbles, the amplitude of booms and busts as well as the banking and the credit spreads. (iv) Higher bailout uncertainty is associated with higher returns’ variability in diversified portfolios and higher systemic risks, (v) Pre-crisis expansionary monetary policy reinforces those effects by inducing higher aggregate leverage levels. (vi) The larger the change in bailout uncertainty and the change in aversion to this uncertainty, the stronger the pre-crisis buildup and the deeper the ensuing crisis.A central policy implication of the analysis is that the vaguest is bailout policy prior to a crisis, the lower is the magnitude of investments destroyed or missed due to errors in evaluating bailout and other intervention policies. On the other hand, the clearer is bailout policy upon the eruption of a crisis, the smaller the contraction of credit and the destruction of investment activity.     

Understanding and managing interest rate risk at banks

Banks in many countries hold significant quantity of bonds issued by their sovereign. This nexus of bank balance sheets with the sovereign debt can amplify in a two-way loop the effect of a rise in sovereign debt yields on banks and vice-versa. The rise in sovereign debt yields tends to be episodic, exhibiting conditional volatility, and banks need to manage this risk proactively to dampen the two-way loop. Lessons are drawn from this perspective for understanding and managing of interest rate (or ‘duration’) risk at Indian banks from their holdings of government securities. Moral hazard implications of regulatory forbearance policies when the two-way loop materializes are also discussed.     

US government TARP bailout and bank lottery behavior

Considerable debate surrounds how the US government's TARP bailout intervention has affected the risk-taking and moral hazard behavior of U.S. banks around the global financial crisis. We examine this issue with a focus on lottery behavior introducing MAX/MIN as a new measure of lotteryness in banking to capture the loss protection from bank bailout guarantees. We find that the TARP bailout increased the likelihood of bank lotteryness and risk shifting. Lottery-like bank equities are riskier after TARP and exhibit fatter right to left tails. A consistent pattern of risk taking and lottery behavior extends both before and after the 2008–2009 crisis, engulfing the largest systemic banks (SIFIs). While confirming that lottery-like bank equities have lower short-term return, we find they exhibit better cumulative long-term return performance. Our findings have important policy implications regarding government intervention in banking crises.     

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.     

International lending of last resort and moral hazard: A model of IMF's catalytic finance

This paper analyzes the trade-off between official liquidity provision and debtor moral hazard in international financial crises. In the model, crises are caused by the interaction of bad fundamentals, self-fulfilling runs and policies by three classes of optimizing agents: international investors, the local government and an international official lender. Limited contingent liquidity support helps to prevent liquidity runs by raising the number of investors willing to lend to the country for any given fundamentals, i.e., it can have catalytic effects. The influence of the official lender is increasing in the size of its interventions and the precision of its information. Unlike the conventional view stressing debtor moral hazard, our model identifies circumstances in which official lending actually strengthens a government's incentive to implement desirable but costly policies.
