Sample text

This uses a time-changed or non-homogeneous Poisson process driving the hazard rate and an assumed recovery rate on default. The benchmark, par or fair market CDS spread for a CDS contract is the fixed fee for CDS protection, such that the present value of the contract is zero and is the premium obtained from the market for a range of different maturities (typically 1–5, 7 and 10 years for active reference entities). Standard CDS contracts have regular fee payments on a 20th March, June, September, December cycle.

The interpolation function over time could be any of the following. (a) Piecewise constant: The hazard rate is assumed constant between birthdays. This is unrealistic but simple and fast to implement; it is typically used in the credit markets where calibrating data is less smooth than human mortality data. (b) Piecewise linear: This is only a little more complicated and nearly as fast. The slope of the hazard rate shows jumps at birthdays but the rate itself is continuous. (c) A smooth function: Some smooth functions also have simple closed form implementations but this is not generally the case.

Currently piecewise constant is more commonly used because minor irregularities in the CDS curve are magnified by piecewise linear calibration and typically lead to a “sawtooth” shape of hazard rate curve. Natural Measure Pricing: Calibrating to Historical Data The above method takes historically derived recovery rates and market-implied hazard rates from traded CDS prices. The alternative approach of using historically derived data for hazard rates is simply applied as follows. Typically the rating for the reference entity is used (or a derived rating may be used).
