A Guide to Modeling Credit Term Structures

We give a comprehensive review of credit term structure modeling methodologies. The conventional approach to modeling credit term structure is summarized and shown to be equivalent to a particular type of the reduced form credit risk model, the fractional recovery of market value approach. We argue that the corporate practice and market observations do not support this approach. The more appropriate assumption is the fractional recovery of par, which explicitly violates the strippable cash flow valuation assumption that is necessary for the conventional credit term structure definitions to hold. We formulate the survival-based valuation methodology and give alternative specifications for various credit term structures that are consistent with market observations, and show how they can be empirically estimated from the observable prices. We rederive the credit triangle relationship by considering the replication of recovery swaps. We complete the exposition by presenting a consistent measure of CDS-Bond basis and demonstrate its relation to a static hedging strategy, which remains valid for non-par bonds and non-flat term structures of interest rates and credit risk.Comment: 54 pages, 13 figures (references fixed

Bank loans non-linear structure of pricing: empirical evidence from sovereign debts

The paper suggests an innovative contribution to the investigation of banking liabilities pricing contracted by sovereign agents. To address fundamental issues of banking, the study focuses on the determinants of the up-front fees (the up-front fee is a charge paid out at the signature of the loan arrangement). The investigation is based on a uniquely extensive sample of bank loans contracted or guaranteed by 58 less-developed countries sovereigns in the period from 1983 to 1997. The well detailed reports allow for the calculation of the equivalent yearly margin on the utilization period for all individual loan. The main findings suggest a significant impact of the renegotiation and agency costs on front-end borrowing payments. Unlike the sole interest spread, the all-in interest margin better takes account of these costs. The model estimates however suggest the non-linear pricing is hardly associated with an exogenous split-up intended by the borrower and his banker to cover up information. Instead the up-front payment is a liquidity transfer as described by Gorton and Kahn (2000) to compensate for renegotiation and monitoring costs. The second interesting result is that banks demand payment for all types of sovereign risk in an identical manner public debt holders do. The difference is that, unlike bond holders, bankers have the possibility to charge an up-front fee to compensate for renegotiation costs. Hence, beyond the information related issues, the higher complexity of the pricing design makes bank loan optimal for lenders on sovereign capital markets, especially relative to public debt, thus motivating for their presence. The paper contributes to the expanding literature on loan syndication and banking related issues. The study also has relevance for the investigation of the developing countries debt pricing

Liquidity Shocks, Systemic Risk, and Market Collapse: Theory and Application to the Market for Perps

Traditional explanations of market crashes rely on the collapse of an asset price bubble or the exacerbation of an information asymmetry sufficient to cause less-informed participants to withdraw from the market. We show that markets can crash even though asset prices have not deviated from fundamental values and information is shared symmetrically among all market participants. We present a model in which markets crash when investors shift their beliefs about the liquidity of the secondary market. While such shifts in liquidity may be a factor in explaining many market crashes, the collapse of the market for perpetual floating-rate notes (perps) provides an especially clear illustration of the theory because a shift in liquidity beliefs appears to have been the sole determinant of the market crash. Such a shift can be precipitated by a systemic liquidity shock that is transitory or permanent. The latter proved to be the case with perps because perceptions of the liquidity of the secondary market were permanently altered. In addition to providing new insights into why markets crash, our findings are particularly relevant for unseasoned financial products that are often priced and marketed on the assumption that liquid secondary markets will develop. The perp episode also highlights the importance of broad placement of securities. Since market liquidity arises endogenously from the diversity of liquidity needs across the investor base, the broader the investor base, the lower the probability of a systemic liquidity shock. We also show how simple modifications in security design can mitigate the impact of such a shock should it occur.

Combination notes: market segmentation and equity transfer

This paper empirically analyzes a particular type of notes observed in securitization transactions: combination notes. Combination notes are formed by combining parts of two or more tranches of securitization transactions, where one part usually consists of a share of the first loss piece. It is analyzed whether combination notes are purely demand driven, or whether combination notes also appear to be structured to enable equity transfer. Results indicate that combination notes serve both purposes: market segmentation severely determines the structuring of combination notes, but risk transfer needs seem to be catered by combination notes as well. Further, an analysis of launch spreads indicates, that the observed equity transfer via combination notes has an impact on the pricing of the ordinary tranches of each deal. This paper makes use of unique data on 126 deals containing 1385 tranches, thereof 398 combination notes

Collateralised loan obligations (CLOs) : a primer

The following descriptive paper surveys the various types of loan securitisation and provides a working definition of so-called collateralised loan obligations (CLOs). Free of the common rhetoric and slogans, which sometimes substitute for understanding of the complex nature of structured finance, this paper describes the theoretical foundations of this specialised form of loan securitisation. Not only the distinctive properties of CLOs, but also the information economics inherent in the transfer of credit risk will be considered, so that we can equally privilege the critical aspects of security design in the structuring of CLO transactions

Credit Spread Dynamics: Evidence from Latin America

This paper examines the behaviour of credit spreads on key sovereign issuers from the Latin American region, which accounts for more than one third of international bond issues by developing, or emerging, markets. Since the late 1990s, credit spreads on Latin American issues have declined broadly inline with those in other emerging markets. Recent empirical analysis has explained this phenomenon by identifying critical macroeconomic factors, including the reduction in systematic risk in individual markets, although the structural models from the theoretical finance literature also predict the importance of key default and interest rate variables. This contribution adds to the understanding of these issues by investigating the application of structural models to the Latin American setting, one historically characterized by excessive volatility and susceptibility to episodes of default.credit spreads, long-run dynamics, Latin America, sovereign bonds, cointegration
