London-based Gatehouse Bank is developing new business lines and widening its investor base as the Islamic wholesale lender looks to build a more stable revenue stream. The bank remains focused on real estate in Europe and the United States but wants to expand its investor base beyond Kuwait, its traditional source of funds, while generating more deals outside the British property market. New chief executive Henry Thompson, who joined in April this year, says he wants to reduce the bank's dependence on transaction fees. This comes after fee and commission income dropped more than two-thirds during last year, partly because of lower deal activity in Britain. The bank also plans to launch an online retail deposit product in December and is considering structuring private investment funds.
