By David French DUBAI, June 10 (Reuters) - Banque Saudi Fransi (BSF), the kingdom's fourth-largest listed lender, will complete a 2 billion riyal ($533 million) capital-boosting sukuk issue by the end of this month, banking sources said on Tuesday. Sources told Reuters last month the bank planned a 2 billion riyal deal by end-June, which would be arranged by its own investment banking arm, Saudi Fransi Capital. BSF's sukuk is the latest capital-boosting Islamic bond sale from a bank in the kingdom. Saudi Investment Bank said last week it had completed a 2 billion riyal sukuk with the same ten-year, **n-call five, lifespan as BSF's. It priced the Islamic bond at 145 bps over six-month Saibor.
