Stuart Crocker, global head of private banking and wealth management at Abu Dhabi Islamic Bank and Merrill Lynch veteran, has left the bank. Regional private banks were supposed to be making a challenge to the dominance of big international players and Crocker was one of the landmark hires to bolster the case for the local Banks. Crocker joined Abu Dhabi Islamic Bank (ADIB) in May 2011 as global head of private banking and wealth management. Apparently, there is no replacement lined up and Crocker's exit comes amid a change of strategy at the bank. ADIB didn't respond to requests for comment.
