Credit-default swaps (CDS) associated with the Dubai Holding Commercial Operations Group LLC, a firm owned by Dubai ruler Sheikh Mohammed bin Rashid al-Maktoum, rose 90 basis points yesterday, part of a record, growing trend in the cost of insuring against losses on debt sold by Dubai companies on speculation that Abu Dhabi, the richest of the U.A.E.’s seven states, will not come to the rescue of those emirate firms who struggle to refinance debt maturing this year.  Per Bloomberg, “lending and investment banking in the Persian Gulf have slowed as oil prices and stock markets in Dubai and Abu Dhabi face the worst global economic slump since the 1930s.  The U.A.E. is also bracing for a real-estate slump after a five-year boom as banks cut back on loans and speculators desert the market.”
