Islamic banks are beginning to make inroads into the banking scene in the US. Chicago-based Devon bank, for example, has transformed itself into an interest-free financing establishment, with Islamic financing accounting for more than 75 percent of the bank's mortgage portfolio. Giant financial institutions in the US now have their own Sharia advisory boards, while banks like Devon Bank in Chicago, with relatively small assets, rely on opinions from the Sharia Advisory Board of America. Muslims in America are becoming a significant demographic force, so Islamic banking is here to stay and offers a lot of potential.
