United Arab Emirates ? Just a year after the global downturn derailed Dubai’s explosive growth, the city is now so swamped in debt that it’s asking for a six-month reprieve on paying its bills — causing a drop on world markets Thursday and raising questions about Dubai’s reputation as a magnet for international investment.

The fallout came swiftly and was felt globally after Wednesday’s statement that Dubai’s main development engine, Dubai World, would ask creditors for a “standstill” on paying back its $60 billion debt until at least May. The company’s real estate arm, Nakheel — whose projects include the palm-shaped island in the Gulf — shoulders the bulk of money due to banks, investment houses and outside development contractors.

In total, the state-backed networks nicknamed Dubai Inc. are $80 billion in the red and the emirate needed a bailout earlier this year from its oil-rich neighbor Abu Dhabi, the capital of the United Arab Emirates.
