Pakistan's central bank has issued guidelines for banks that want to be fully-fledged sharia compliant, setting a three-year time frame for applicants to complete the process. The rules aim to accelerate the growth of Islamic banking in the country. Eligible applicants must have existing Islamic finance operations and the conversion process must start within six months of approval. After the conversion of conventional branches, the applicant can then apply for a fully-fledged Islamic banking license. Such conversions are rare in Islamic finance but are seen as a way to increase the scale of the bank and widen its reach into under-served rural areas. Islamic banking in Pakistan currently includes five fully-fledged Islamic banks and 16 conventional banks offering Islamic financial products. As of March, they held assets worth 1.9 trillion rupees ($17.9 billion), a 16% increase from a year earlier and 11.7% of total banking assets. However, their capitalization and profitability ratios remain below the industry average.
