Vanguard: Islamic Banking makes headway in global finance—IMF
Since the inception of Islamic banking about three decades ago, the number and reach of Islamic financial institutions worldwide has risen from one institution in one country in 1975, to more than 300 institutions operating in more than 75 countries.
The entire banking systems of Sudan and Iran are based on Islamic finance principles. Although Islamic banks are concentrated in the Middle East and Southeast Asia, they are also niche players in Europe and the United States. According to McKinsey & Co., Islamic banking assets and assets under management reached $750 billion in 2006, and the Islamic finance sector is expected to reach $1 trillion by 2010.
