The findings indicate that monthly spread changes were strongly currency-dependent during the period May 1999{\textendash}May 2001. Sector-by-rating factor returns are at best weakly correlated across currencies, and U.S. dollar spread returns are generally more volatile than the other two by a factor of two or three. This is contrary to what would be expected from covered interest arbitrage. The conclusion is that analysts should estimate credit factor risk models separately in each market, as risk forecasting models using a single set of spread factors for different markets will not be accurate.}, issn = {0095-4918}, URL = {https://jpm.pm-research.com/content/29/2/90}, eprint = {https://jpm.pm-research.com/content/29/2/90.full.pdf}, journal = {The Journal of Portfolio Management} }
