Greetings from down under where I am on a week's whistle-stop tour. It is easy to sit in London and think that Europe is the universe and London its centre, but there are other thriving capital markets around the world. So I thought I would go forth and remind myself that there are other places where people buy and sell shares, bonds, currencies, commodities and their derivatives.

Where better than Sydney, the city that brought forth Mr M? (He, needless to say, did not accompany me as he wants to get in a bit more golf before winter sets in.)
