A pricing model for sovereign bond

Abstract

Similar to the modeling used to evaluate ccnporate boncls, where it is a put optioo. 011 corporate assets, we modeled sovereign bonds. Instead of company's assets as underlining assets, we used foreign excbange reserves. The results show a fundamental pricing model for sovereign bond and an optimum relation between the debt size, term, mix between floating and fixed interest payments, and size of reserves. The model is tested with a Brazilian BradyBond.
