Banks must mind their own back yards

With trouble at financial institutions in the Middle East concentrated in the Gulf, particularly in the UAE, Kuwait and to some extent Bahrain, the banks know that putting all of their investment eggs in the Gulf's basket makes for inadequate and ultimately dangerous geographical narrowness.
Given the Gulf's unique circumstances, it may make more sense for banks to sell off lines of business where they are weak and acquire parts of other banks where they want to become stronger.
