Moody’s on Wednesday downgraded five Dubai government-related issuers, citing the tighter conditions under which the government is likely to extend financial support.

The ratings agency downgraded from A3 to A1 DP World, the global ports operator; Dubai Water & Electricity Authority; and the investments arm of Dubai International Financial Centre; and from A3 to Baa1 Jebel Ali Free Zone; and the non-financial assets of Dubai Holding, the investment vehicle of the emirate’s ruler.
