In recent years, the volatility of financial assets has significantly increased. High causes instability in markets and increases portfolio risks. Under these conditions, modeling volatility, determining relationships, spillovers are important for market actors. this study, period January 2, 2010 - April 10, 2020, it was investigated spillover correlation relationship between Borsa Istanbul (BI...

This paper presents a simple reduce-form approach to pricing credit derivatives. The definition of default is purely based on the market value of a risky bond and its potential recovery value. A risky bond is treated as a riskless bond with an embedded short position on a barrier option. The risky bond market implicitly prices this barrier option. The default implied volatility (DIV) curve for ...

This paper compares the pricing of credit risk in the bond market and the fast-growing credit default swap (CDS) market. The empirical findings confirm the theoretical prediction that bond spreads and CDS spreads move together in the long run. Nevertheless, in the short run this relationship does not always hold. The deviation is largely due to different responses of the two markets to changes ...

This paper examines the dynamic relationship between credit risk and liquidity in the sovereign bond market in the context of the European Central Bank (ECB) interventions. Using a comprehensive set of liquidity measures obtained from a detailed, quote-level dataset of the largest interdealer market for Italian government bonds, we show that changes in credit risk, as measured by the Italian so...

Credit risk has become a topical issue since the 2007 Credit Crisis, particularly for its impact on the valuation of OTC derivatives. This becomes critical when the credit risk of entities involved in a contract either as underlying or counterparty become highly correlated as is the case during macroeconomic shocks. It impacts the valuation of such contracts through an additional term, the cred...

We propose a general setting for pricing single-name knock-out credit derivatives. Examples include Credit Default Swaps (CDS), European and Bermudan CDS options. The default of the underlying reference entity is modeled within a doubly stochastic framework where the default intensity follows a CIR++ process. We estimate the model parameters through a combination of a cross sectional calibratio...

In this paper we compare market prices of credit default swaps with model prices. We show that a simple reduced form model outperforms directly comparing bonds’ credit spreads to default swap premiums. We find that the model yields unbiased premium estimates for default swaps on investment grade issuers, but only if we use swap or repo rates as proxy for default-free interest rates. This indica...
