Islamic finance can be seen as part of a wider movement towards the promotion of sustainability as a key element of economic life. The basic premise under sharia law that no one should profit purely from money leads to a shift in both parties' perspective away from the short-term transaction and towards the longer-term relationship and its consequences. Islamic finance is becoming an important part of important emerging economies in the Middle East and Asia – high-growth markets where American businesses will want to compete and succeed. And the Muslim population in the United States is continuing to grow and can be an engine for further growth here at home. Ignoring these developments will be harmful to American banks and investors, as well as to the American economy itself.
