Because Shariah compliance is essential for all Islamic banks, it does not distinguish one Islamic bank from another. Hence it is a foundation attribute. About 25 years ago, Price Waterhouse made a distinction between foundation attributes and leverage attributes. Foundation attributes convey no competitive advantage. Al Rayan Bank is the only Islamic bank in the UK which targets ordinary retail customers. The bank's homepage gives very prominent coverage to its Shariah compliance. That is because Al Rayan is not competing against other retail Islamic banks but rather seeking to create a retail Islamic finance market where none has existed before.
