Family bonding: Two banks in Dubai get new Maktoum chairs. So what?

HH Sheikh Ahmed bin Mohammad bin Rashid Al Maktoum has been appointed Chairman of the Board of Directors of Noor Islamic Bank (NIB) and therefore replaced Sheikh Ahmed bin Saeed Al Maktoum.
Sheikh Ahmed bin Saeed Al Maktoum replaced in exchange Ahmed Humaid Al Tayer as the head of the UAE’s biggest bank by assets Emirates NBD.
The question is what could be the motive behind this. Bankers like Mashreq Capital CEO Kadir Hussein say that “People change senior management and board because they want things to move in another strategic direction.”
