I am PhD student in credit risk.I want to calibrate the default probability by using the real CDS spread. Do you know where can I download the data for credit default swap (CDS) ? THe data for defaultable zero bond price is also OK. Creditgrades, creditex, enron don't have the history data. Morganmarkets needs an account. I am very sad now. I can't progress without any data. If any one of you have history data, I would like to buy it from you. Please pm me with any suggestion or help.Thanks a lot.

I suggest you talk to the people in research at JP Morgan,Moody's, S&P, Fitch and other banks and non-banks.Moodys has research avaliable on their website. You have to log in, but a student can sign up. I just did. Then download some of their credit related research.Look at the names of the people who do the research andcall them and ask for the dept. head to give you the data for yourresearch. Maybe you can even ask them for a stipend forexpenses or whatever. Call as many I-Bank research dept. heads as you can, or maybeeven junior people. Someone will likely give in and give you the data.Good luck.
