According to KPMG Oman, conventional banks in Oman that do not offer any Islamic banking services will face the threat to lose numerous customers which will prefer a bank that offers Shari'ah-compliant financial services. Khalid Yousaf, Director of Islamic Finance Advisory Services, KPMG Oman, claims that opening an Islamic window operation is a safe strategy. As a reason he points out that it requires less capital while, at the same time, sharing a common cost base with additional business.
