I am in the process of building zero coupon curves for some countries in the Eurozone.
I have the following data sets:
- Euribor and EONIA
- Swap rates
- Bond price and yields
The bond prices (and thus yields) reflect the relative credit worthiness of the sovereign issuer (a point that has come to the fore most recently). For the longer dated time buckets therefore, the yields "make sense". At the shorter end however, the official rates seems to be Euribor and EONIA (for s/n-o/n) - I can't see how this makes sense - since these are the same data points I would be using to evaluate "high quality" debt from Germany (for example). I can't see how it makes sense to use these same points for constructing yield curves for any of the peripheral Euro-zone countries - as the credit risk does not seem to be reflected at the short end - am I missing something?
What data points do professionals out there use to construct yield curves for Eurozone countries (with the exception of Germany)?
