Fitch Ratings has downgraded its rating for the Islamic Republic of Iran from BB– to B+, to take account of what it calls the “escalating confrontation between Iran and the international community over Iran’s nuclear programme.” Although it contends that material sanctions are still some way off, it argues that the risk is increasing and events “are becoming increasingly unpredictable”. The agency acknowledges, though, that with high oil prices Iran’s external financial position remains strong.
