| Abstract: | The paper proposes a simple, new, analytical framework for assessing the cost and benefits of macroprudential policies. It proposes a measure of net benefits in terms of parameters that can be estimated: the probability of crisis, the loss in output given crisis, policy effectiveness in bringing down both the probability and damage during crisis, and the output-cost of a policy decision. It discusses three types of policy leakages and identifies instruments that could best minimize the leakages. Some rules of thumb for policymakers are provided. |

| Abstract: | There has recently been a proliferation of new quantitative tools as part of various initiatives to improve the monitoring of systemic risk. The "SysMo" project takes stock of the current toolkit used at the IMF for this purpose. It offers detailed and practical guidance on the use of current systemic risk monitoring tools on the basis of six key questions policymakers are likely to ask. It provides "how-to" guidance to select and interpret monitoring tools; a continuously updated inventory of key categories of tools ("Tools Binder"); and suggestions on how to operationalize systemic risk monitoring, including through a systemic risk "Dashboard." In doing so, the project cuts across various country-specific circumstances and makes a preliminary assessment of the adequacy and limitations of the current toolkit. |

| Abstract: | Credibility is the bedrock of any crisis stress test. The use of stress tests to manage systemic risk was introduced by the U.S. authorities in 2009 in the form of the Supervisory Capital Assessment Program. Since then, supervisory authorities in other jurisdictions have also conducted similar exercises. In some of those cases, the design and implementation of certainelements of the framework have been criticized for their lack of credibility. This paper proposes a set of guidelines for constructing an effective crisis stress test. It combines financial markets impact studies of previous exercises with relevant case study information gleaned from those experiences to identify the key elements and to formulate their appropriate design. Pertinent concepts, issues and nuances particular to crisis stress testing are also discussed. The findings may be useful for country authorities seeking to include stress tests in their crisis management arsenal, as well as for the design of crisis programs. |

| Abstract: | In this paper we present a novel Bayesian approach for default probability estimation. The methodology is based on multivariate contingent claim analysis and pair copula theory. Balance sheet data are used to asses the firm value and to compute its default probability. The firm pricing function is obtained via a pair copula approach, and Monte Carlo simulations are used to calculate the default probability distribution. The methodology is illustrated through an application to defaulted firms data. |

| Abstract: | Theory and empirical evidence suggest short-run interactions between capital and risk. This paper analyzes the effects of reinsurance, as a new endogenous decision variable, on this policy mix. We examine this issue using a system of simultaneous equations applied to the U.S. property-liability insurance industry. The results identify significant interactions between capital, risk and reinsurance. The relationship between risk and capital is positive, indicating the effectiveness of regulatory mechanisms. Reinsurance is negatively associated with capital, for which it appears to act as a substitute. These results are sensitive to the level of capital held in excess of the regulatory minimum requirements. Weakly capitalized firms adjust their reinsurance and risk levels more quickly and try to rebuild an appropriate capital buffer. Unlike other decision variables, the capital ratio converges toward a long-run target level. |

| Abstract: | Government support to banks through the provision of explicit or implicit guarantees affects the willingness of banks to take on risk by reducing market discipline or by increasing charter value. We use an international sample of bank data and government support to banks for the periods 2003-2004 and 2009-2010. We find that more government support is associated with more risk taking by banks, especially during the financial crisis (2009-10). We also find that restricting banks' range of activities ameliorates the moral hazard problem. We conclude that strengthening market discipline in the banking sector is needed to address this moral hazard problem. |

| Abstract: | A new methodology to construct synthetic volatility derivatives is presented. The underlying asset price process is very general, since equity, commodities and interest rates are included. The focus is on volatility swaps and volatility swap options, but much more derivatives may be considered. The proposed methods optimize the conditional value at risk of the non-hedged risk, and yields both bid and ask prices, as well as optimal hedging strategies for both purchases and sales. Upper bounds for the broker capital losses under very negative scenarios are given. Numerical experiments are presented so as to illustrate the performance in practice of this new approach. |

| Abstract: | Estimating the effect of Federal Reserve’s announcements of Large-Scale Asset Purchase (LSAP) programs on corporate credit risk is complicated by the simultaneity of policy decisions and movements in prices of risky financial assets, as well as by the fact that both interest rates of assets targeted by the programs and indicators of credit risk reacted to other common shocks during the recent financial crisis. This paper employs a heteroskedasticity-based approach to estimate the structural coefficient measuring the sensitivity of market-based indicators of corporate credit risk to declines in the benchmark market interest rates prompted by the LSAP announcements. The results indicate that the LSAP announcements led to a significant reduction in the cost of insuring against default risk—as measured by the CDX indexes—for both investment- and speculative-grade corporate credits. While the unconventional policy measures employed by the Federal Reserve to stimulate the economy have substantially lowered the overall level of credit risk in the economy, the LSAP announcements appear to have had no measurable effect on credit risk in the financial intermediary sector. |

| Abstract: | We propose a network-based model of credit contagion and examine the e�ects of idiosyncratic and systemic shocks to individual banks and the banking system. The banking system is built as a network in which banks are connected to each other through the interbank market. The microstructure captures the relation between debtors and creditors, and the macroeconomic events capture the sensitivity of the banks' �nancial strenght to macroeconomic events, such as housing. We have demonstrated that while idiosyncratic shocks do not have a potential to substantially disturb the banking system, macroeconomic events of higher magnitudes could be highly harmful, especially if they also spur contagion. In a concerted default of more banks, the stability of a banking system tends to decrease disproportionately. In addition, credit risk analysis is highly sensitive to the network topology and exhibits a nonlinear characteristic. Capital ratio and recovery rates are two additional factors that contribute to the stability of the �nancial system. |

| Abstract: | In this paper we compare equity- and credit investors’ opinions on the price formation in the equity market. More exactly, we invert the CreditGrades model in order to back out credit-implied stock prices and stock return volatilities from credit default swap spreads for the firms in the DJIA index. The credit-implied stock prices often deviate significantly from actual stock prices over the longer term. Meanwhile, their day-to-day movements are significantly correlated with actual stock returns for most firms in the DJIA index. In an attempt to demonstrate potential applications of credit-implied stock prices we construct simple “capital structure arbitrage” trading strategies based on past credit-implied prices. Our strategies only require the buying and selling of stocks and differ from traditional cross-capital structure strategies by being suitable for retail investors and other investors without access to the credit derivatives market. The credit-implied volatilities, in turn, behave rather similarly to observed stock market volatilities but without any ghost effects. We demonstrate how an alternative credit-based “fear gauge”, comparable to the VIX index but emanating from the credit market, can be constructed using the credit-implied volatilities. We call this implied volatility index the Credit-Implied Volatility Index (CIVIX) index. Finally, a plot of the entire term-structure of implied volatilities demonstrates a distinct maturity volatility skew. |

| Abstract: | The G-20 Data Gaps Initiative has called for the IMF to develop standard measures of tail risk, which we identify in this paper with systemic risk. To understand the conditions under which tail risk is present, it is first necessary to develop a measure of what constitutes a systemic stress, or tail, event. We develop such a measure and uses it to assess the performance of eleven near-term systemic risk indicators as ‘early’ warning of distress among top financial institutions in the United States and the euro area. Two indicators perform particularly well in both regions, and a couple of other simple indicators do well across a number of criteria. We also find that the sizes of institutions do not necessarily correspond with their contribution to spillover risk. Some practical guidance for policies is provided. |

| Abstract: | Credit rating agencies face a difficult trade-off between delivering both accurate and stable ratings. In particular, its users have consistently expressed a preference for rating stability, driven by the transactions costs induced by trading when ratings change frequently. Rating agencies generally assign ratings on a through-the-cycle basis whereas banks' internal valuations are often based on a point-in-time performance, that is they are related to the current value of the rated entity's or instrument's underlying assets. This paper compares the two approaches and assesses their impact on rating stability and accuracy. We find that while through-the-cycle ratings are initially more stable, they are prone to rating cliff effects and also suffer from inferior performance in predicting future defaults. This is because they are typically smooth and delay rating changes. Using a through-the-crisis methodology that uses a more stringent stress test goes halfway toward mitigating cliff effects, but is still prone to discretionary rating change delays. |

| Abstract: | This paper reports in detail on a survey that was circulated to reserve managing central banks of IMF member countries in April 2012. The survey aims to gain further insight into how reserve managers have reacted to the crisis to date. The survey also aims to understand how reserve managers arrive at their strategic asset allocation and how they operate their risk management frameworks in practice. Some of the key themes that emerge from the survey include potential procyclical and counter cyclical behavior by reserve managers, increased focus placed on returns and wide variability across countries in how the currency composition of reserves is derived. |
