Saudi Arabia’s central bank has joined the Islamic financial regulator Accounting and Auditing Organisation for Islamic Financial Institutions (AAOIFI). The move could increase cross-border financial deals in the region, as guidelines will apply to all financial institutions within Saudi Arabia. Both conventional and Islamic banks will now be subject to the same standards, potentially encouraging deals with other Muslim countries. AAOIFI Chairman Sheikh Ebrahim bin Khalifa Al Khalifa stated that the addition of the Saudi central bank would help foster closer collaboration with the kingdom. Saudi Arabia may now hold ambitions of becoming a global heavyweight in the Islamic finance sector. However, it will face intense competition from Malaysia, South Africa and the UK.
