The Church of Scotland has joined forces with Islamic finance experts to draw up a “practical ethical financial solution” to help the poor while sticking to the principles of both faiths. The agreement, which was announced on Tuesday, marks an unusual attempt to promote cross-religious financial innovation. Backers say it is too early to say what “solution” the initiative could yield, but possibilities include the creation of a new financial institution with cross-faith legal articles. The Scottish initiative is supported by international Muslim clerics and experts including Lamido Sanusi, a former Nigerian central bank governor famed for cleaning up the banking sector and now one of the country’s highest Islamic authorities.
