Qatar’s Barwa Bank and the International Bank of Qatar (IBQ), which last year agreed to merge, plan to cut more than 150 jobs and to appoint Barwa’s boss as chief executive of the combined lender, two sources familiar with the matter told Reuters.

The banks reached a final merger agreement late last year to create a lender with total assets of 80 billion riyals ($22 billion).

The combined lender will be rebranded as Lusail Bank, the sources said, adding the integration would begin towards the end of the first quarter. Barwa Bank did not respond to a request for immediate comment. A shake-up has been long mooted in Qatar’s banking system, where 18 local and international commercial banks serve a population of around 2.6 million.

Barwa Bank said last month its shareholders had approved the proposed merger.
