Real estate bubbles and their subsequent collapses frequently accompany financial crises, especially the ones that linger and last a long time. The current Dubai default is merely the latest episode in the unwinding of a global real estate glut. Local authorities denied there was any problem right up to the end. Until the excesses are wrung out of the system, sustainable economic recovery is not possible - and even then it's not guaranteed. The crisis in Japan began 19 years ago and they have yet to get their economy fully functioning again. Japan also provides the worse case scenario for a drop in real estate prices - 90% for residential real estate and 99% for class A office buildings in Tokyo. While Dubai might not get that bad, real estate price drops there could be considerable.

The UAE central bank has pledged to provide funding for both domestic and foreign banks in an attempt to prevent bank runs in the region. It is estimated that a quarter of Dubai's $80 billion in real estate debt came from UAE banks. British and eurozone banks may hold as much as 70% of the remaining $60 billion. Exposure in the U.S. and Japan seems to be fairly minimal. Stock markets have been closed in the Gulf region due to an Islamic holiday since the crisis unfolded on Thanksgiving day. Dubai and Abu Dhabi opened on Monday and were down 7% and 8% respectively. The extent of contagion to other bourses in the region remains to be seen. Dubai is particularly vulnerable because it is not an oil producer; the other oil-rich countries in the region should ultimately be in much better shape.
