Abu Dhabi is not going to crow publicly over Dubai’s troubles. But it will use the opportunity to assert control over its upstart neighbor. The price for Abu Dhabi’s help could be prize assets like airline Emirates. Dubai has little choice but to do what it is told.

Dubai is unable to service the $80 billion debt it has amassed during its meteoric rise to wannabe global financial hub. Oil-rich Abu Dhabi holds the political and financial trump cards. Not only is it the capital of the United Arab Emirates, its ruler is head of the UAE’s seven desert states — squeezed between Saudi Arabia and Oman.

Dubai’s success threatened the balance of power between the two emirates. Abu Dhabi has developed quickly, but not at the speed of Dubai, where until a year ago new skyscrapers popped out of the desert every few days.

A property market crash and the end of free-flowing credit have taken their toll. Abu Dhabi has already lent Dubai at least $10 billion and another $5 billion indirectly via two of its banks. That won’t be the end of it. Dubai has nowhere else to turn, particularly now it has alienated the international capital markets by admitting it can’t meet the debts of flagship holding company Dubai World. Abu Dhabi can afford to bail out Dubai, but it has not been immune to losses itself and won’t be signing blank checks.
