The authors would like to thank, for their comments and suggestions, Stijn Claassens, Daniel Oks and Enrico Perotti, as well as the participants in a seminar held at the World Bank in October 1996. 2 Abstract This paper analyzes some aspects of the workings of the Brady bond (restructured LDC debt) market. It concentrates on the effects of the Mexican crisis on the risk assessment (as measured by the stripped spread) of other Brady countries (particularly Poland). The main findings are: i) the risk premium (on a single country) has one unit root; this is consistent with the hypothesis that risk premia reflect new information accruing to the market; ii) comovements among stripped yields were stronger during the high volatility period of the Mexican crisis; in particular, in our case-study on Mexico and Poland, we do not reject cointegration for the period July 94-July 95, but we do reject it for the period July 95-July 96. iii) the crisis has had a strong permanent effect on the risk assessment on Mexico (about 550 bs. pts.); iv) different Brady bonds responded differently to the Mexican crisis: countries with similar pre-crisis mean and volatility reacted in a similar way (in terms of both absolute deviation and degree of comovement with the Mexican bonds).
